CrowdStrike vs Defender vs SentinelOne: 100% MITRE [2026]

Three vendors now define the endpoint detection and response conversation for most IT buyers: CrowdStrike Falcon, Microsoft Defender for Endpoint, and SentinelOne Singularity. Each takes a different route to the same job, stopping ransomware, catching credential theft, and giving security teams the forensic trail to figure out what happened after an alert fires. The differences show up in agent architecture, pricing structure, independent test scores, and how much manual tuning a security team has to do to keep false positives down.

This comparison pulls from CrowdStrike’s and SentinelOne’s fiscal year 2026 earnings releases, AV-Comparatives’ 2025 enterprise test rounds, MITRE’s 2025 ATT&CK Enterprise Evaluation results, and published vendor pricing pages to lay out what each platform actually costs and how it performs. It is built for security leads, IT admins, and MSPs deciding which endpoint detection and response platform to run in 2026, whether that means a first EDR deployment or a migration off legacy antivirus.

What Endpoint Detection and Response Actually Means in 2026

Endpoint detection and response grew out of a simple gap: traditional antivirus matches files against known-bad signatures, but it has no way to catch an attacker who logs in with stolen credentials and uses built-in Windows tools to move around a network. EDR platforms instead watch process behavior, network connections, and registry changes in real time, then use behavioral analytics and machine learning to flag activity that looks like an attack pattern even when no matching malware signature exists.

By 2026, the category has split into two overlapping tiers. EDR tools focus on the endpoint itself: laptops, servers, virtual machines. XDR (extended detection and response) platforms pull in signals from email, identity systems, cloud workloads, and network traffic, correlating them into a single incident timeline. CrowdStrike, Microsoft, and SentinelOne all sell products that span both categories now, which is part of why they get compared against each other so often: a buyer evaluating “EDR” and a buyer evaluating “XDR” frequently end up looking at the same three vendors.

Market-research estimates cited by Mordor Intelligence’s endpoint detection and response market report put the top five EDR vendors at roughly 58% of total 2025 category revenue, with CrowdStrike, Microsoft, and SentinelOne all inside that group alongside Palo Alto Networks and Trend Micro. Analyst estimates referenced in trade coverage put CrowdStrike around 18-22% EDR market share, Microsoft around 16-20%, and SentinelOne around 12-16% as of late 2025, though these figures are directional analyst modeling rather than audited numbers, since none of the three companies report EDR-specific market share as a filed metric.

That three-way split is why this comparison matters for 2026 buyers specifically. A few years ago, “best EDR platform” mostly meant picking between CrowdStrike and a handful of smaller specialists. Now Microsoft has pushed Defender for Endpoint into enterprise deals it would have lost outright five years ago, purely on the strength of Microsoft 365 E5 bundling, while SentinelOne has carved out a reputation for autonomous, agent-driven response that doesn’t lean on a 24/7 human SOC.

Ransomware economics are a big part of why this category keeps growing. When an attacker can encrypt an entire fileshare in minutes and demand a six- or seven-figure payment, the cost of a missed detection is no longer measured in a single infected laptop, it’s measured in days of downtime and, increasingly, regulatory notification obligations. That math is why boards that used to treat endpoint security as a line-item IT expense now treat EDR platform selection as a risk-committee decision, with security leadership expected to justify the choice against named benchmarks rather than gut feel.

CrowdStrike vs Microsoft Defender vs SentinelOne: Full Specs Comparison

The table below lines up the core architecture and feature differences across all three endpoint detection and response platforms, based on each vendor’s current published product documentation.

Capability	CrowdStrike Falcon	Microsoft Defender for Endpoint	SentinelOne Singularity
Agent architecture	Single lightweight cloud-native sensor	Built into Windows OS; separate agent for macOS/Linux	Single autonomous agent, static + behavioral AI
OS support	Windows, macOS, Linux, ChromeOS, mobile	Windows, macOS, Linux, Android, iOS	Windows, macOS, Linux, containers, cloud workloads
Detection model	Cloud-based ML + threat graph correlation	Cloud-based ML + Microsoft threat intelligence	On-device static AI plus cloud behavioral AI
Offline / air-gapped protection	Limited (cloud lookups needed for full features)	Limited (some cloud dependency)	Full protection maintained without cloud connectivity
Managed threat hunting	Falcon OverWatch (add-on, human-led)	Defender Experts for XDR (add-on)	Vigilance MDR (add-on)
AI assistant / copilot	Charlotte AI	Security Copilot (integrated across Microsoft stack)	Purple AI (launched 2025)
SIEM / log platform	Falcon Next-Gen SIEM	Microsoft Sentinel (separate product)	Singularity Data Lake
Ransomware rollback	Yes, via Falcon sensor	Limited, via cloud-based automated remediation	Yes, native one-click rollback
Native identity protection	Falcon Identity Protection (add-on)	Deeply integrated with Entra ID / Active Directory	Singularity Identity (add-on)
Cloud workload protection	Falcon Cloud Security (add-on)	Defender for Cloud (separate product)	Singularity Cloud Security (add-on)
Deployment complexity	Low; single-sensor rollout	Low if already on Microsoft 365; higher standalone	Low; single-agent rollout
Best-fit environment	Large enterprise SOC, MSSP, multi-OS estates	Microsoft 365 / Entra-centric organizations	Ransomware-sensitive, lean-SOC, autonomous response

The architectural split shows up most clearly in how each vendor handles a disconnected endpoint. CrowdStrike and Microsoft both lean on cloud correlation for their most advanced detections, which means a laptop that’s been offline for days has thinner protection until it reconnects. SentinelOne’s pitch has long centered on keeping its behavioral AI engine local to the endpoint, so protection doesn’t degrade when connectivity drops, a detail that matters more for field workers, ships, and remote industrial sites than for a standard office fleet.

Pricing Compared: What Each EDR Platform Actually Costs in 2026

Pricing is where the three platforms diverge the most in how they even present cost. CrowdStrike publishes per-device list pricing directly on its site. Microsoft prices Defender for Endpoint per user, not per device, and folds its top tier into broader Microsoft 365 E5 bundles. SentinelOne does not publish list pricing at all, quoting per-endpoint costs directly to prospects, which is common in the EDR space but makes a clean side-by-side harder for buyers doing early-stage research.

Platform	Tier	Price	Billing unit	Notes
CrowdStrike Falcon	Go	$7.99/month ($59.99/year)	Per device	Entry AV replacement tier
CrowdStrike Falcon	Pro	$14.99/month ($99.99/year)	Per device	Adds EDR to Go tier
CrowdStrike Falcon	Enterprise	$19.99/month ($184.99/year)	Per device	Adds threat hunting, XDR features
CrowdStrike Falcon	Elite	Custom quote	Per device	Full platform, identity, cloud add-ons
Microsoft Defender	for Business	$3.00/month	Per user	Included free in Microsoft 365 Business Premium
Microsoft Defender	for Endpoint Plan 1	$3.00/month	Per user	Next-gen AV, attack surface reduction only
Microsoft Defender	for Endpoint Plan 2	$5.20/month	Per user	Full EDR; included in Microsoft 365 E5
SentinelOne Singularity	Core	Custom quote	Per endpoint	Prevention + basic detection
SentinelOne Singularity	Control	Custom quote	Per endpoint	Adds device control, firewall control
SentinelOne Singularity	Complete	Custom quote	Per endpoint	Full EDR/XDR, rollback, Purple AI

On paper, Microsoft looks like the budget option: $3.00 per user for the entry Defender for Business tier undercuts CrowdStrike’s cheapest Go tier by roughly $5 per seat per month, and $5.20 for full EDR coverage under Plan 2 is well below CrowdStrike’s $19.99 Enterprise tier. But the comparison isn’t quite apples-to-apples. CrowdStrike bills per device, so a user with a laptop and a phone counts as two licenses; Microsoft bills per user, covering multiple devices under some plans. Full official pricing detail is available on CrowdStrike’s pricing page and Microsoft’s Defender for Endpoint documentation.

SentinelOne’s refusal to publish list pricing is itself a data point. Reseller and review-site estimates place Singularity Complete in a range that competes with CrowdStrike’s Enterprise and Elite tiers, but because SentinelOne negotiates per deal, actual cost depends heavily on endpoint count, contract length, and add-on modules like Vigilance MDR. Buyers comparing SentinelOne against the other two should budget time for a sales cycle before they get a real number, not just a demo.

None of these list prices capture the full bill, either. Falcon Next-Gen SIEM, Microsoft Sentinel, and Singularity Data Lake all charge separately for log ingestion and retention once an organization wants to keep more than a baseline window of telemetry, and that cost scales with fleet size and how verbose the logging policy is set. A security team budgeting for “EDR” without pricing out data retention separately is one of the most common ways a signed contract ends up costing more than the sales quote implied, regardless of which of the three vendors wins the deal.

Benchmark Results: MITRE ATT&CK, AV-Comparatives, and Independent Testing

Vendor marketing in the EDR space leans hard on independent test results, and for good reason: unlike consumer antivirus, there’s no simple “download and scan” way for a buyer to evaluate detection quality themselves before signing a contract. Three test bodies carry the most weight for 2026 evaluations: MITRE’s ATT&CK Evaluations, AV-Comparatives’ business and enterprise test rounds, and, to a lesser degree, Gartner Peer Insights and G2 user review aggregates.

In the 2025 MITRE ATT&CK Enterprise Evaluation, CrowdStrike Falcon reported 100% detection and 100% protection across all tested adversary techniques, with zero false positives, according to CrowdStrike’s own published results summary. That result builds on a pattern CrowdStrike has repeated across multiple MITRE rounds, and it’s the single most-cited benchmark figure in CrowdStrike’s own sales materials. Independently verified detection-percentage results specific to Microsoft Defender for Endpoint and SentinelOne Singularity in the same 2025 MITRE Enterprise round were not available in the public sources reviewed for this comparison at time of writing, which is itself worth flagging: CrowdStrike is considerably more aggressive about publicizing MITRE results than either competitor.

AV-Comparatives offers a more directly comparable dataset because it tests multiple vendors under identical conditions and publishes results for all of them in the same report. In the Malware Protection Test Enterprise, March 2025, both Microsoft Defender and CrowdStrike scored 99.3% malware protection rate with zero false alarms on common business software. In the Business Security Test 2025 (August-November) round, CrowdStrike posted a 98.0% protection rate but showed above-average false positives on non-business software, while Microsoft again logged zero false alarms on common business software. SentinelOne did not appear with a directly comparable protection-rate figure in the AV-Comparatives rounds reviewed for this piece.

Test	CrowdStrike Falcon	Microsoft Defender	SentinelOne Singularity
MITRE ATT&CK Enterprise 2025	100% detection, 100% protection, 0 false positives	Not independently published in reviewed sources	Not independently published in reviewed sources
AV-Comparatives Enterprise Malware Protection, March 2025	99.3% protection, 0 false alarms	99.3% protection, 0 false alarms	Not included in reviewed round
AV-Comparatives Business Security Test, Aug-Nov 2025	98.0% protection, above-average false positives (non-business software)	0 false alarms on common business software	Not included in reviewed round

The honest reading of this data: CrowdStrike and Microsoft both post strong, independently verified protection scores in the 98-100% range across 2025 test rounds, with Microsoft showing a slight edge on false-positive discipline in the business security round. SentinelOne’s marketing repeats strong historical MITRE and AV-TEST results from earlier evaluation rounds, but this comparison could not independently verify SentinelOne-specific 2025 protection-rate figures from AV-Comparatives’ most recent published rounds, so treat vendor-supplied SentinelOne benchmark claims with the same scrutiny you’d apply to any single-source number.

Independent testing has also gotten more important as attackers lean on AI-generated malware variants to slip past signature-based detection. AV-Comparatives and MITRE both design their evaluation rounds around realistic adversary technique chains rather than known malware samples, which is closer to how a real 2026 intrusion unfolds: living-off-the-land binaries, credential replay, and lateral movement through legitimate admin tools, not a single flagged executable. That’s precisely the pattern behind incidents like the Windows Netlogon flaw, where attackers escalate privileges using a protocol weakness rather than dropping obviously malicious files, and it’s why a platform’s behavioral-detection score matters more than a simple virus-scan pass rate.

CrowdStrike Falcon: Strengths, Weaknesses, and Where It Fits

CrowdStrike built its reputation as the incumbent enterprise EDR platform, and its FY2026 numbers back that up: full-year revenue of $4.81 billion, up 22% year over year, with ending annual recurring revenue of $5.25 billion as of January 31, 2026, a 24% year-over-year gain, according to CrowdStrike’s Q4 and full-year FY2026 earnings coverage. That scale funds a threat-intelligence operation and a managed-hunting team (Falcon OverWatch) that smaller vendors can’t easily match.

Falcon’s single-sensor architecture is genuinely lightweight compared to older-generation endpoint suites, and its 2025-2026 push into Falcon Next-Gen SIEM plus Raptor AI-powered inline threat disruption extends the platform well past classic EDR into full XDR territory. For a security operations center running its own analysts, Falcon gives the deepest self-service investigation tooling of the three platforms.

The weaknesses are cost and complexity for smaller teams. Falcon Enterprise at $19.99 per device per month is the most expensive list-priced tier among the three vendors, and the full platform experience (identity protection, cloud security, next-gen SIEM) requires stacking multiple paid modules. CrowdStrike also still carries reputational weight from the July 2024 global outage caused by a faulty content update, a widely reported incident that grounded flights and disrupted hospitals worldwide. It remains the reference point competitors bring up in sales conversations, even as CrowdStrike has continued shipping product updates through 2025 and 2026.

Microsoft Defender for Endpoint: Strengths, Weaknesses, and Where It Fits

Microsoft’s advantage isn’t really about EDR features in isolation, it’s about what Defender for Endpoint plugs into. Any organization already running Microsoft 365 E5 or Entra ID gets identity signal, email security, and endpoint detection correlated inside one console without buying a separate platform. Microsoft expanded that story further in March 2026 with enhanced Defender XDR capabilities, adding AI-driven threat detection and cross-domain analytics that tie endpoint alerts directly to identity and cloud app signals.

Price is the other clear advantage. At $3.00 per user per month for Plan 1 and $5.20 for Plan 2, Microsoft undercuts both competitors on list price, and Defender for Business ships free inside Microsoft 365 Business Premium, meaning some organizations are already paying for EDR without realizing it’s included. Full plan detail is documented on Microsoft’s official Defender for Endpoint page.

The tradeoffs show up outside pure Microsoft shops. Licensing across Plan 1, Plan 2, Business, and E5 bundles is genuinely confusing, and organizations report needing a licensing specialist just to figure out which SKU covers which capability. Defender’s threat-hunting tools are also less mature as a standalone, human-led service compared to CrowdStrike’s OverWatch, and mixed-OS environments (heavy Linux or macOS fleets) tend to get a less polished experience than Windows-first estates.

SentinelOne Singularity: Strengths, Weaknesses, and Where It Fits

SentinelOne’s pitch is autonomy: a single agent that runs static AI models locally, on the endpoint, rather than depending entirely on cloud round-trips for every detection decision. That matters most for ransomware response, where SentinelOne’s native one-click rollback can restore an encrypted machine to its pre-attack state without a restore-from-backup cycle. The company reported FY2026 full-year revenue of $1,001.3 million and ending ARR of $1,119.1 million as of January 31, 2026, per SentinelOne’s fourth-quarter and full fiscal-year 2026 results, crossing the billion-dollar ARR mark.

SentinelOne’s 2025 launch of Purple AI, a generative-AI threat-hunting assistant that converts natural-language questions into detection queries, targets the same problem CrowdStrike’s Charlotte AI and Microsoft’s Security Copilot address: SOC analysts spending too much time writing query syntax instead of investigating. For lean security teams without a dedicated detection-engineering function, that kind of natural-language interface can meaningfully cut the skill floor needed to run the platform well.

The tradeoffs are scale and transparency. SentinelOne’s roughly 12-16% estimated EDR market share is real but smaller than either competitor, meaning fewer publicly documented large-enterprise deployments to reference, less third-party tooling built around its API by default, and fewer independently published 2025 benchmark results in the test rounds reviewed for this piece. Pricing opacity compounds this: buyers can’t rough out a budget from a public price list the way they can with CrowdStrike or Microsoft.

Real-World Deployment Scenarios: Matching the Platform to the Organization

EDR buying decisions rarely come down to a single feature. They come down to what an organization already has, how big its security team is, and what kind of attack it’s most afraid of. These five scenarios reflect the patterns that show up repeatedly in how each platform gets deployed, drawn from how CrowdStrike, Microsoft, and SentinelOne each position their own case studies and partner documentation around fleet size, industry, and incident history.

• A 3,000-employee financial services firm with a 24/7 SOC: Falcon Enterprise plus OverWatch fits organizations that want to run their own detection engineering and lean on CrowdStrike’s threat graph for cross-customer intelligence, an approach large regulated firms favor when audit requirements demand a documented, mature EDR history.
• A 150-person professional services company already on Microsoft 365 E5: Defender for Endpoint Plan 2 is effectively a marginal-cost decision here, since the organization is already paying for E5 and gains XDR correlation across email, identity, and endpoints without a new procurement cycle.
• A regional healthcare network that has been hit by ransomware once already: SentinelOne’s autonomous rollback directly targets the recovery-time problem that made the first incident costly, letting IT restore an encrypted endpoint in minutes rather than waiting on a full backup restore.
• An MSP managing endpoints across 40 small-business clients: multi-tenant management console quality and per-device pricing predictability both matter more than any single detection benchmark, which is why CrowdStrike and SentinelOne both maintain dedicated MSP partner programs, while Microsoft’s licensing model is harder to resell across separate client tenants.
• A manufacturing company with field technicians and industrial sites with unreliable connectivity: SentinelOne’s locally resident detection engine keeps working when a device is offline for extended stretches, a scenario where cloud-dependent detection from CrowdStrike or Microsoft is functionally degraded until the device reconnects.

These scenarios also explain why ransomware and credential-theft coverage keep showing up in EDR sales conversations. Attacks like The Gentlemen ransomware operation, which overtook Qilin’s victim count in recent reporting, and credential-stealing malware like Lumma Stealer, which resurfaced after two law-enforcement takedowns, are exactly the threat classes EDR platforms are built to catch before they escalate into a full breach. Large-scale credential and data breaches, including incidents affecting KDDI’s 12.2 million users and 200 firms tied to a four-year-old leaked credential, are frequently traced back to an endpoint that either had no EDR agent installed or had one that wasn’t tuned to catch the initial access technique.

Best Use Cases: Which EDR Platform Should You Choose

Beyond the deployment scenarios above, here’s a more direct breakdown by evaluation priority.

• Choose CrowdStrike Falcon if: you run or want a dedicated SOC, need the broadest independently verified MITRE track record, and budget is secondary to detection depth and managed threat-hunting quality.
• Choose Microsoft Defender for Endpoint if: you’re already licensed for Microsoft 365 E5 or Business Premium, want the lowest incremental cost, and prioritize identity and email correlation over standalone endpoint depth.
• Choose SentinelOne Singularity if: ransomware recovery speed is the top concern, your environment includes offline or intermittently connected devices, and you want a smaller, lean-SOC-friendly footprint with AI-assisted investigation.
• Choose CrowdStrike or SentinelOne over Defender if: your estate is majority Linux or macOS, where both platforms offer more mature non-Windows detection than Microsoft’s Windows-first product history.
• Choose Microsoft over the other two if: procurement simplicity matters more than best-in-class detection, since bundling into an existing Microsoft agreement avoids a new vendor contract and a new console for IT to learn.

Migration Guide: Switching EDR Platforms Without Leaving Coverage Gaps

Ripping out one EDR agent and installing another sounds simple until you consider that every endpoint has to stay protected during the transition. Security teams that rush this step end up with silent coverage gaps that only surface during the next incident. The process below reflects how CrowdStrike, Microsoft, and SentinelOne all recommend structuring a cutover, regardless of which platform you’re migrating to.

1. Inventory every endpoint first. Pull a full device list from your current EDR console, your MDM/Intune tool, and your network access control logs, then reconcile the three. Endpoints that show up in only one source are usually the ones that get missed during cutover.
2. Run both agents in parallel during a pilot window. Install the new agent alongside the old one on a pilot group (typically 5-10% of the fleet) for two to four weeks. Most EDR agents are built to coexist temporarily, though CrowdStrike explicitly documents supported coexistence configurations with Microsoft Defender for organizations running both during migration.
3. Tune detection policies before full rollout. Default detection policies generate more noise than a tuned environment. Use the pilot window to suppress known-safe internal tooling and adjust sensitivity, rather than pushing default policies to the full fleet and drowning the SOC in false positives on day one.
4. Migrate by business unit, not all at once. Sequencing the rollout by department lets the security team handle alert volume in manageable batches and gives IT a rollback path if a specific device image or software stack conflicts with the new agent.
5. Decommission the old agent only after confirming telemetry flow. Verify the new platform is receiving and correctly classifying events from each migrated endpoint before removing the legacy agent, not just confirming the install succeeded.
6. Retrain the SOC on the new console before go-live, not after. Investigation workflows, query syntax, and alert triage differ meaningfully between Falcon, Defender, and Singularity consoles. Analysts who learn the new interface during a live incident make slower, worse decisions.

A typical silent uninstall during a Windows-based migration, run through a management tool like Intune or SCCM, looks like this for a CrowdStrike Falcon sensor removal once the replacement agent is confirmed healthy:

WindowsSensor.exe /uninstall /quiet CID=<your_customer_id>
# Confirm removal
Get-Service -Name CSFalconService -ErrorAction SilentlyContinue

The specific removal command differs by vendor and by whether the deployment uses a maintenance token, but the sequencing principle holds across all three platforms: confirm the new agent is reporting correctly before removing the old one, never the reverse.

Timeline expectations matter too. For a fleet under 1,000 endpoints, a well-planned migration with a proper pilot window typically runs four to eight weeks from kickoff to full decommission of the old agent. Larger, multi-site enterprises with segmented networks and change-control requirements should budget two to four months, particularly if the migration also involves consolidating a separate antivirus product and a separate SIEM into the new platform’s unified console. Rushing that timeline to hit a contract renewal deadline is how coverage gaps happen, since the pilot window is the step teams cut first when a migration falls behind schedule.

EDR/XDR Market in 2026: Revenue, ARR, and Vendor Stability

Vendor financial health matters more in security tooling than in most software categories, because switching EDR platforms mid-contract is expensive and disruptive. A vendor that’s losing money or shrinking is a real procurement risk, not just an abstract concern.

CrowdStrike’s FY2026 numbers show a company still growing at scale: $4.81 billion in full-year revenue, up 22% year over year, and $5.25 billion in ending ARR, up 24%, as reported in its fourth-quarter and full fiscal-year 2026 results released March 4, 2026. SentinelOne’s FY2026 results, released March 12, 2026, show $1,001.3 million in full-year revenue and $1,119.1 million in ending ARR, crossing the billion-dollar ARR threshold for the first time and confirming it’s grown into a durable second-tier public security vendor rather than an acquisition target running out of runway.

Microsoft doesn’t break out Defender for Endpoint revenue as a standalone line item, folding it into its broader Security business segment, which Microsoft has previously disclosed crossing $20 billion in annual revenue across the full security portfolio (identity, cloud, endpoint, and email combined). That makes a direct product-line comparison against CrowdStrike or SentinelOne impossible from public filings, but it does confirm Microsoft has no financial incentive to under-invest in Defender, since it’s a retention lever for the much larger Microsoft 365 subscription business.

The gap between CrowdStrike’s $5.25 billion ARR and SentinelOne’s $1.12 billion ARR is also a useful lens for procurement risk. CrowdStrike’s scale means it can absorb a bad quarter, a lawsuit, or a slow enterprise sales cycle without threatening its roadmap. SentinelOne’s smaller base makes it more sensitive to a slowdown, though a billion-dollar ARR company growing at the pace SentinelOne has posted through FY2026 is a long way from the acquisition-bait profile smaller EDR vendors carried five years ago. Buyers running procurement risk assessments should weigh vendor scale as one input alongside benchmark performance and pricing, not as a disqualifying factor on its own.

Common Mistakes to Avoid When Choosing an EDR Platform

A few patterns show up repeatedly in botched EDR evaluations, regardless of which platform the organization ends up choosing.

• Treating list price as total cost. Add-on modules for identity protection, cloud workload security, managed threat hunting, and next-gen SIEM can double the effective per-endpoint cost on any of these three platforms.
• Skipping the false-positive question. A platform with a marginally higher detection rate but a heavier false-positive burden can cost more in analyst time than it saves in caught threats, which is why the AV-Comparatives false-alarm columns matter as much as the protection-rate columns.
• Ignoring non-Windows coverage until after signing. Organizations with meaningful Linux or macOS fleets should test detection quality on those specific operating systems during the pilot, not assume feature parity with the Windows agent.
• Underestimating the licensing map. Especially with Microsoft’s tiered plans, buyers frequently discover mid-deployment that the SKU they purchased doesn’t include a capability they assumed was standard.
• Not budgeting migration time. A rushed cutover, without a parallel-run pilot period, is the single most common cause of coverage gaps during an EDR platform switch.

The Verdict: Which EDR Platform Wins in 2026

There isn’t a single winner across all three platforms, because the data doesn’t point to one. On independently verified detection performance, CrowdStrike’s 100% MITRE ATT&CK Enterprise result and its 99.3% AV-Comparatives enterprise protection score put it at or near the top of every benchmark reviewed here, and its scale ($5.25 billion ARR) funds threat intelligence smaller vendors can’t match. That performance comes at the highest list price of the three, and it’s the right trade for organizations that run their own SOC and treat detection depth as the top purchasing criterion.

Microsoft Defender for Endpoint wins on cost and integration, not on raw detection ceiling. Its matching 99.3% AV-Comparatives protection score alongside CrowdStrike, at roughly a quarter of the price for Plan 2, makes it the strongest choice for any organization already committed to the Microsoft 365 ecosystem, and arguably the most underrated option for mid-market companies who assume they need to shop outside their existing licensing to get real EDR coverage.

SentinelOne is the platform to choose when the deciding factor is ransomware recovery speed or offline resilience rather than raw benchmark supremacy. Its FY2026 numbers prove the business is durable at scale, but its comparative lack of publicly available 2025 independent benchmark data (relative to CrowdStrike and Microsoft) means buyers evaluating it purely on third-party test scores will have a harder time verifying vendor claims than they will with the other two platforms.

The practical takeaway for most buyers: if you’re already deep in Microsoft 365, start your evaluation with Defender for Endpoint and only look elsewhere if it fails your pilot. If you’re building or already running a dedicated SOC and detection depth is non-negotiable, CrowdStrike remains the benchmark leader to beat. If ransomware recovery time or field-device connectivity are your top risk, put SentinelOne through a proof-of-concept before you rule it out on pricing opacity alone.

Frequently Asked Questions

Is CrowdStrike Falcon better than Microsoft Defender for Endpoint?

CrowdStrike scored 100% detection and protection in the 2025 MITRE ATT&CK Enterprise Evaluation, while Microsoft Defender matched CrowdStrike’s 99.3% protection rate in AV-Comparatives’ March 2025 enterprise malware protection test. CrowdStrike generally leads on standalone detection depth and managed threat hunting; Microsoft Defender leads on price and native integration for Microsoft 365 environments. Neither is universally “better” independent of what the buying organization already runs.

What is the difference between EDR and XDR?

Endpoint detection and response focuses specifically on laptops, servers, and other endpoints. Extended detection and response (XDR) expands that same detection and correlation approach to email, identity systems, cloud workloads, and network traffic, combining signals from all of them into a single incident view. CrowdStrike, Microsoft, and SentinelOne all sell products spanning both categories today.

How much does CrowdStrike Falcon cost per endpoint?

CrowdStrike Falcon’s published list pricing runs from $7.99 per device per month for the entry Go tier up to $19.99 per device per month for the Enterprise tier, billed annually at $59.99 and $184.99 respectively. The top Elite tier is custom-quoted based on the modules and endpoint count involved.

Does SentinelOne publish public pricing?

No. SentinelOne Singularity’s Core, Control, and Complete tiers are all quote-based, with pricing determined by endpoint count, contract length, and add-on modules like Vigilance MDR. Buyers need to go through a sales conversation to get an actual number, unlike CrowdStrike and Microsoft, which both publish list prices.

Can you run two EDR agents on the same endpoint during migration?

Temporarily, yes. CrowdStrike documents supported coexistence configurations with Microsoft Defender specifically for migration windows, and most vendors expect a parallel-run pilot period before full cutover. Running two EDR agents long-term as a permanent setup is not recommended, since it can cause resource conflicts and duplicate alerting, but a two-to-four-week overlap during a planned migration is standard practice.

Which EDR platform is best for a small business?

For small businesses already on Microsoft 365 Business Premium, Defender for Business is already included at no extra cost, making it the lowest-friction starting point. Organizations outside the Microsoft ecosystem, or those specifically worried about ransomware recovery time, should evaluate CrowdStrike Falcon Go or SentinelOne Singularity Core as entry-tier alternatives.

Does Microsoft Defender for Endpoint work on Linux and macOS?

Yes, Microsoft Defender for Endpoint supports Windows, macOS, Linux, Android, and iOS. However, its detection maturity on non-Windows operating systems is generally considered less developed than its Windows coverage, and both CrowdStrike and SentinelOne are commonly viewed as stronger choices for majority-Linux or majority-macOS environments.

What happened with the CrowdStrike outage, and does it affect Falcon’s reliability today?

In July 2024, a faulty CrowdStrike content update caused widespread Windows system crashes, grounding flights and disrupting hospitals and other services globally. It remains one of the most cited incidents in enterprise IT history and a common talking point competitors raise during sales conversations. CrowdStrike has continued to ship product updates and post strong independent benchmark results through 2025 and 2026, including its 100% MITRE ATT&CK Enterprise Evaluation result, but the incident is still a relevant risk factor for buyers evaluating vendor concentration and change-management practices.
