MITRE ATT&CK Evals

the most credible independent EDR evaluation: MITRE Engenuity runs adversary simulations using real threat actor TTPs against submitted EDR platforms, measuring detection visibility, alert quality, and response capability. All three platforms participate; results are published without scores to prevent marketing manipulation

E5 licensing

Microsoft 365 E5 includes Defender for Endpoint Plan 2, Defender for Identity, Defender for Office 365 Plan 2, Defender for Cloud Apps, and Microsoft Sentinel -- the complete Microsoft security stack. Organizations already paying for E5 receive MDE at no incremental cost, making the cost comparison with CrowdStrike and SentinelOne asymmetric

AI-powered detection

all three platforms claim AI/ML-based threat detection, but the implementations differ: CrowdStrike Falcon AI uses behavioral models trained on its threat intelligence network; SentinelOne's Singularity AI focuses on autonomous response and rollback; MDE's AI uses Microsoft's threat intelligence signals across 65 trillion daily signals from Microsoft's global infrastructure

Autonomous remediation

SentinelOne's primary differentiation: Singularity can autonomously detect, isolate, and remediate threats without human intervention, including rollback of ransomware-encrypted files using VSS snapshots -- a capability that MDE and CrowdStrike also offer but which SentinelOne has historically made more central to its platform story

Detection Quality: The MITRE ATT&CK Evaluation Baseline

MITRE Engenuity's ATT&CK Evaluations are the most credible independent benchmark for EDR detection quality. All three platforms participated in the most recent enterprise evaluations, and the results provide a useful starting point -- with important caveats.

What MITRE measures

MITRE evaluations simulate real adversary behaviors (recent evaluations have used DPRK-affiliated Lazarus Group and ransomware operator TTPs) and measure: whether the platform detected each attack step (detection coverage), how the detection was presented (alert quality -- was it an automated alert or required human correlation?), and whether response actions were available. MITRE does not produce rankings or scores to prevent vendors from optimizing for the metric. Raw results are published at attackevals.mitre-engenuity.org.

Recent evaluation results (summary)

All three platforms consistently demonstrate high detection coverage in MITRE evaluations -- coverage rates above 90% for most techniques are common across MDE, CrowdStrike, and SentinelOne. The differentiators in recent evaluations have been in alert quality (how clearly the detection was presented -- as a correlated alert vs raw telemetry) and response actions (which platforms enabled automated responses vs manual-only). SentinelOne has consistently scored well on protection (blocking attacks before execution); CrowdStrike has strong detection breadth with high-quality correlated alerts; MDE benefits from Microsoft's threat intelligence signals across its product ecosystem.

The real-world detection quality caveat

MITRE evaluations use known adversary TTPs in controlled conditions -- the evaluation environment is not your actual environment. Detection quality in production is heavily influenced by your endpoint configuration (are GPO policies set correctly for MDE to have full telemetry?), your tuning investment (CrowdStrike and SentinelOne both require significant policy tuning to reduce noise), and your analysts' ability to act on alerts. A platform with 95% MITRE coverage and 400 daily false positives provides worse outcomes than a platform with 88% coverage and 50 actionable daily alerts.

Microsoft Defender for Endpoint

MDE is the native endpoint security platform for Windows environments, built into the Microsoft 365 Defender suite and tightly integrated with the Microsoft security ecosystem.

The E5 licensing dynamic

MDE Plan 2 is included in Microsoft 365 E5 and Microsoft Defender for Business. Organizations that are already paying for E5 (which many large enterprises are for Teams, SharePoint, and Exchange compliance features) receive MDE at no incremental endpoint security cost. This changes the cost comparison fundamentally: the decision is not MDE vs CrowdStrike on a per-endpoint basis, but rather whether the additional capability of CrowdStrike or SentinelOne justifies paying for a second EDR platform when MDE is already licensed.

Microsoft ecosystem integration depth

MDE's integration with the Microsoft security ecosystem is unmatched by either competitor: native integration with Microsoft Sentinel (SIEM), Defender for Identity (AD attack detection), Defender for Office 365 (email threat correlation), Defender for Cloud (cloud workload protection), and Entra ID (identity context in endpoint alerts). In an organization running the Microsoft security stack, MDE provides security signal correlation that requires substantial custom integration to achieve with CrowdStrike or SentinelOne.

Strengths

Cost (included in E5), deep Windows integration (native kernel visibility without a third-party agent), Microsoft Threat Intelligence (65 trillion signals/day across Azure, Bing, Xbox, and enterprise telemetry), Unified Security Operations Center (combined MDE + Sentinel + Defender for Identity in a single investigation surface), and ASR (Attack Surface Reduction) rules for hardening Windows endpoints against common attack techniques. macOS, Linux, Android, and iOS support has matured significantly in recent releases.

Weaknesses

MDE's agent on non-Windows platforms (macOS, Linux) is less mature than on Windows -- kernel extension requirements on macOS create deployment friction in some enterprise environments. Alert quality (signal-to-noise ratio) historically required more tuning investment than CrowdStrike to reach operational maturity. The Microsoft Defender portal (security.microsoft.com) provides a unified interface but can feel overwhelming given the breadth of the Microsoft security suite. Incident response capabilities (live response, remote isolation) are solid but less mature than CrowdStrike's incident response-focused tooling.

CrowdStrike Falcon

CrowdStrike Falcon is the market share leader in enterprise EDR among organizations that are actively selecting an endpoint security platform rather than defaulting to what is already licensed.

Architecture: single lightweight agent

Falcon's single-agent architecture is a genuine operational differentiator: one agent covering EDR, antivirus, device control, USB control, firewall management, vulnerability management, and identity threat detection. Organizations that have replaced multi-agent endpoint security stacks (legacy AV + EDR + vulnerability scanner) with Falcon report meaningful reduction in endpoint management complexity and resource consumption. The Falcon sensor is lightweight (typically <1% CPU overhead) and cloud-first -- telemetry goes to CrowdStrike's cloud for analysis rather than processing locally.

Threat intelligence and adversary tracking

CrowdStrike tracks 230+ named adversary groups (APTs, criminal groups, hacktivist groups) with detailed TTPs, infrastructure, and targeting profiles. The adversary intelligence is embedded in Falcon alerts -- when Falcon detects a technique associated with a specific threat actor, the alert surfaces that context. This adversary-attribution approach is CrowdStrike's strongest differentiation from MDE and SentinelOne: Falcon alerts tell you not just what happened but which threat actor's playbook it matches.

Strengths

Best-in-class incident response tooling (Falcon Forensics, RTR live response), adversary intelligence integration, proven performance at scale (500K+ endpoint deployments), strong managed detection and response (MDR) via Falcon Complete, and the Falcon platform's modular add-on architecture allowing organizations to start with EDR and add modules (Identity Protection, Cloud Security, Next-Gen SIEM) as needed. CrowdStrike's SOC integrations and API ecosystem are the most mature in the category.

Weaknesses

CrowdStrike is the most expensive option when paid for standalone (not as an E5 bundle). The modular pricing model can result in significant cost growth as organizations add modules -- Falcon Complete MDR, Identity Protection, and Exposure Management add materially to base EDR licensing. The July 2024 faulty content update incident (that caused 8.5 million Windows BSODs) raised questions about CrowdStrike's update validation processes, though the company implemented significant safeguards following the incident.

SentinelOne Singularity

SentinelOne differentiates on autonomous response, AI-powered detection, and the Singularity Data Lake -- a high-throughput data platform that underpins both SIEM and EDR use cases.

Autonomous response and Storyline

Singularity's Storyline technology contextualizes every process, file, network connection, and registry change into a coherent attack narrative (a 'Storyline') that updates in real time as the attack progresses. When Singularity detects a threat, it can autonomously remediate: killing malicious processes, quarantining files, rolling back ransomware-encrypted files using shadow copies, and isolating the endpoint from the network -- without human intervention. Autonomous response reduces mean time to respond (MTTR) in scenarios where SOC analyst availability is a constraint.

Singularity Data Lake

Singularity Data Lake (SDL) is SentinelOne's high-throughput data lake that ingests EDR telemetry, cloud logs, identity events, and third-party data sources. SDL positions SentinelOne as a SIEM alternative (or complement) -- organizations can query all security telemetry from a single interface rather than shipping EDR data to a separate SIEM. For SOC teams evaluating whether to consolidate their SIEM and EDR data plane, SDL provides a compelling path to simplification.

Strengths

Autonomous remediation depth (rollback is more robust than MDE's equivalent), Storyline AI-contextualized alerts reduce analyst investigation time, Singularity Data Lake for unified security data, strong cross-platform support (Windows, macOS, Linux, Kubernetes, cloud VMs), and competitive pricing relative to CrowdStrike's equivalent capability tier. SentinelOne's MITRE evaluation results have consistently shown strong protection (blocking attacks) and detection coverage.

Weaknesses

SentinelOne's threat intelligence and adversary tracking capabilities are less mature than CrowdStrike's -- Falcon's adversary intelligence integration is a category differentiator that SentinelOne has not matched. The Singularity platform's breadth (EDR + SIEM + CNAPP) has led some customers to report that individual modules are less mature than best-of-breed point solutions. Enterprise support reputation is more mixed than CrowdStrike's among large-scale deployments.

Head-to-Head Decision Framework

The choice between these three platforms should be driven by your existing ecosystem, operational model, and specific capability priorities.

Choose Microsoft Defender for Endpoint if...

You are already paying for Microsoft 365 E5 and want to maximize your existing licensing investment. Your environment is predominantly Windows and deeply integrated with the Microsoft ecosystem (Entra ID, Sentinel, Defender for Identity). You want a single unified security operations interface for endpoint, identity, and email. You have a lean security team and want to reduce platform proliferation.

Choose CrowdStrike Falcon if...

You are doing an active EDR selection (not defaulting to E5) and want the platform with the most mature incident response tooling. Adversary intelligence and threat actor attribution in alerts are important to your SOC's investigation workflow. You have a complex multi-platform environment (Windows + macOS + Linux + cloud) and need a proven single agent across all. You want the highest-confidence choice for a Fortune 500-scale deployment.

Choose SentinelOne if...

Autonomous response speed is critical -- you need containment without analyst availability. You want to consolidate SIEM and EDR telemetry into a single data platform (Singularity Data Lake). You are CrowdStrike-qualified but need a lower-cost option at equivalent capability tier. You are prioritizing strong macOS and Linux coverage alongside Windows.

The hybrid consideration

Some organizations run MDE for Windows endpoints (leveraging E5 licensing) and CrowdStrike or SentinelOne for macOS and Linux where MDE's agent is less mature. This hybrid model maximizes cost efficiency while ensuring platform maturity on all OS types -- but adds operational complexity from managing two EDR platforms simultaneously.

The bottom line

The three-way EDR decision is ultimately an ecosystem and operational model question, not a detection quality question -- all three platforms detect the vast majority of threats that matter. If you are an E5 shop, the burden of proof is on CrowdStrike or SentinelOne to justify incremental cost beyond what MDE already provides. If you are running an active EDR selection independent of Microsoft licensing, CrowdStrike is the safest large-enterprise choice and SentinelOne is the strongest challenger with better autonomous response and a lower price point. Run a 30-day proof of concept in your environment with real analyst interaction -- the platform that produces the right volume and quality of actionable alerts for your SOC is the right platform, regardless of benchmark results.
