Introduction
Traditional antivirus products operate on signature detection — they compare files and processes against a database of known malware patterns. That model fails against modern threats: fileless attacks that execute entirely in memory, ransomware that disables AV services before encrypting files, and living-off-the-land attacks that abuse legitimate system tools to evade detection.
Endpoint Detection and Response (EDR) platforms address this gap with behavioral monitoring: instead of matching signatures, EDR continuously records process executions, network connections, file operations, and registry changes — and applies machine learning to identify anomalous patterns that indicate a threat actor. When a threat is detected, EDR provides both automated response (isolate the endpoint, kill the process) and forensic telemetry for investigation.
This guide compares three EDR platforms: CrowdStrike Falcon, SentinelOne, and Microsoft Defender for Endpoint. Pricing is drawn from each vendor's published rate cards and Microsoft's licensing documentation as of Q1 2026.

How We Evaluated Each Platform
Five criteria shaped this comparison:
- Detection capability — performance in independent MITRE ATT&CK Evaluations.
- Autonomous response — can the platform contain and remediate threats without human intervention?
- Platform coverage — what operating systems and workloads are fully supported?
- Forensic telemetry — what data is captured for post-incident investigation?
- Total cost of ownership — per-endpoint cost including required add-ons.
1. CrowdStrike Falcon
Overview
CrowdStrike Falcon is a cloud-native endpoint protection platform built on a single lightweight agent (the Falcon sensor) that streams telemetry to the CrowdStrike Security Cloud for analysis. The platform was designed from the outset without an on-premise management server or local signature updates — all detection logic runs in the cloud against continuously updated threat intelligence.
The platform holds a 4.7/5 G2 rating across 700+ reviews as of Q1 2026. In MITRE ATT&CK Enterprise Evaluations, CrowdStrike achieves top-tier detection rates.
Pricing
| Module | Price (approx., annual billing) | Coverage |
|---|---|---|
| Falcon Go | ~$4.99/endpoint/mo | Next-gen AV, basic threat intelligence |
| Falcon Pro | ~$8.99/endpoint/mo | Full EDR, real-time response |
| Falcon Enterprise | ~$14.99/endpoint/mo | Full EDR + threat intelligence + identity protection |
| Falcon Complete (MDR) | Custom | Fully managed detection and response |
Pricing source: crowdstrike.com/products/pricing as of Q1 2026.
Strengths
- MITRE ATT&CK performance — CrowdStrike consistently ranks among the top-performing platforms in independent evaluations, testing detection against advanced persistent threat (APT) behaviors.
- Threat Intelligence integration — Falcon Intelligence surfaces threat-actor attribution and campaign context alongside endpoint alerts.
- Cloud-native architecture — sub-1% CPU impact in normal operation (per CrowdStrike's benchmarks). No on-premise infrastructure required.
- Falcon Complete MDR — managed detection and response service allows SMEs without a dedicated SOC team to outsource 24/7 threat monitoring at a per-endpoint cost.
- Identity protection (Falcon Identity Threat Protection) monitors Active Directory for credential-based attacks.
Trade-offs
- No built-in 1-click rollback — VSS snapshots or separate backup are required for full file recovery after ransomware.
- Pricing is typically quote-based for Pro and above — not self-serve.
- Alert richness can overwhelm smaller IT teams without a dedicated security analyst.
Recommended For
SMEs and mid-market companies with security analyst resources, organizations in regulated industries where threat intelligence matters, teams considering MDR as an alternative to in-house SOC staffing.
2. SentinelOne
Overview
SentinelOne is built around autonomous AI-driven response — its patented Behavioral AI engine detects and responds to threats without human intervention. When a threat is detected, it can automatically kill the malicious process, quarantine files, and roll back all changes made since the attack began — including restoring encrypted files to their pre-ransomware state.
The platform holds a 4.8/5 G2 rating across 1,500+ reviews as of Q1 2026 — the highest of the three platforms reviewed.
Pricing
| Tier | Price (approx., annual billing) | Key Features |
|---|---|---|
| Singularity Core | ~$6/endpoint/mo | Next-gen AV, basic EDR, behavioral AI |
| Singularity Control | ~$8/endpoint/mo | Full EDR, firewall control, device control |
| Singularity Complete | ~$14/endpoint/mo | Full EDR + threat intelligence + 1-click rollback + ActiveEDR |
Pricing source: sentinelone.com/pricing as of Q1 2026.
Strengths
- 1-click rollback — Storyline technology tracks all OS-level operations associated with a threat. When ransomware is detected, a single command reverses all file changes, registry modifications, and process creations — restoring the pre-attack state.
- ActiveEDR — autonomous response detects, contains, and remediates threats in seconds without waiting for analyst review. Reduces attacker dwell time to near-zero for organizations without 24/7 SOC coverage.
- Storyline AI — every endpoint event is linked to a root-cause Storyline showing the full attack chain: initial entry, lateral movement, persistence mechanism, and payload.
- Broad platform coverage — Windows, macOS, Linux (kernel and user-space), Kubernetes containers, and major cloud VMs.
- Highest G2 rating among the three platforms reviewed (4.8/5, 1,500+ reviews).
Trade-offs
- Autonomous response requires trust calibration — the default aggressive posture may generate false-positive actions in early deployment.
- Complete tier pricing (~$14/endpoint/mo) is in the same range as CrowdStrike Enterprise.
- Vigilance MDR is available at an additional per-endpoint cost.
Recommended For
Organizations wanting autonomous threat response without dedicated SOC resources, SMEs that have experienced ransomware and want native file rollback, environments with diverse OS (Windows + Linux + macOS + containers).
3. Microsoft Defender for Endpoint
Overview
Microsoft Defender for Endpoint (MDE) is Microsoft's enterprise EDR solution built on the Windows Defender antimalware engine. For organizations already running Microsoft 365 Business Premium, E3, or E5 licenses, MDE provides EDR capability without a separate endpoint agent on Windows devices — the Defender sensor is a native OS component.
The platform holds a 4.4/5 G2 rating across 400+ reviews as of Q1 2026. In MITRE ATT&CK Evaluations, MDE has consistently improved and is now a credible top-tier performer in Windows-focused evaluations.
Pricing
| Plan | Price (standalone) | Included In |
|---|---|---|

| Plan 2 | $5.20/user/mo | Microsoft 365 E5, Microsoft 365 E5 Security |
| Plan 2 (standalone add-on) | $5.20/user/mo | Add-on to M365 Business/E3 |
For organizations on Microsoft 365 E5 ($57/user/mo), MDE Plan 2 is included at no incremental cost.
Pricing source: microsoft.com/security/business/endpoint-security/microsoft-defender-endpoint as of Q1 2026.
Strengths
- Zero-incremental-cost for M365 E5 customers — the most cost-effective path to full EDR for Microsoft-native environments.
- Native Windows integration — no additional agent required on Windows 10/11. Eliminates agent compatibility issues and reduces performance overhead.
- Microsoft Defender XDR integration — correlated alerts across endpoints, email, identity (Entra ID), cloud apps, and network — significant detection advantage in the Microsoft ecosystem.
- Threat and Vulnerability Management — built-in TVM engine continuously scans endpoints for unpatched software and exploitable vulnerabilities, prioritizing by severity and exploitability score.
- Microsoft Intune integration — conditional access policies (only healthy endpoints access corporate resources) and automated remediation workflows.
Trade-offs
- Full feature parity outside Windows is limited — macOS and Linux agents have fewer advanced features than the Windows-native implementation.
- No 1-click rollback equivalent to SentinelOne's Storyline rollback.
- Alert volume can be high in complex environments without proper tuning.
- Advanced threat intelligence requires a separately licensed add-on.
Recommended For
Organizations on Microsoft 365 Business Premium, E3, or E5 where MDE is partially or fully included, Windows-centric IT environments, organizations using Microsoft Intune and Entra ID, SMEs wanting enterprise EDR at lowest total cost of ownership.

FAQ
Q: What is the difference between EDR and traditional antivirus?
Traditional antivirus detects known malware by matching files against a signature database. EDR continuously monitors endpoint behavior — process executions, network connections, file operations — and detects anomalous patterns indicating a threat, regardless of whether it matches a known signature. EDR is designed for advanced threats that evade signature detection.
Q: Does Microsoft Defender for Endpoint replace the need for a third-party AV?
Yes. When fully configured, Microsoft Defender for Endpoint Plan 2 provides full EDR, next-generation antivirus, and threat and vulnerability management. Organizations running Plan 2 do not require a separate third-party AV product on Windows devices.
Q: What is MITRE ATT&CK and why does it matter for EDR evaluation?
MITRE ATT&CK is a publicly available knowledge base of adversary tactics, techniques, and procedures (TTPs) observed in real attacks. The MITRE ATT&CK Evaluations are independent tests that emulate advanced threat groups and measure how well each EDR platform detects them — a useful proxy for real-world detection capability without vendor bias.
Q: Can SMEs without a security team effectively use CrowdStrike or SentinelOne?
Yes, with a managed service. CrowdStrike Falcon Complete and SentinelOne Vigilance MDR provide 24/7 threat monitoring and response by the vendor's analysts. SMEs pay a per-endpoint fee and the vendor's SOC handles alert triage, investigation, and containment.
Q: How does SentinelOne's 1-click rollback work in ransomware scenarios?
SentinelOne's Storyline technology journals every OS-level change associated with a running process in real time. When ransomware is detected and terminated, the rollback function reverses all OS changes — including file encryption, registry modifications, and new process creations — restoring files to their pre-attack state. This requires the Complete tier.
Q: What is the total cost comparison for 50 endpoints across these platforms?
At Q1 2026 published pricing for 50 endpoints annually: CrowdStrike Falcon Pro ~$5,394/yr; SentinelOne Singularity Complete ~$8,400/yr; Microsoft Defender Plan 2 (standalone) ~$3,120/yr. Microsoft is significantly cheaper for Windows-centric environments where M365 licensing overlaps.
Conclusion
For most SMEs, the endpoint protection decision in 2026 comes down to infrastructure and team capacity, not raw detection capability — all three platforms perform competitively in independent evaluations.
If your organization is Windows-centric and already paying for Microsoft 365 Business Premium, E3, or E5, Microsoft Defender for Endpoint is the most cost-effective path to enterprise EDR. If you need cross-platform coverage and best-in-class autonomous response without a dedicated SOC, SentinelOne Singularity Complete delivers the strongest autonomous remediation — including file rollback. If threat intelligence and MITRE ATT&CK top-quartile performance are primary criteria, CrowdStrike Falcon is the standard against which others are measured.
