Three EDR platforms cover the modern endpoint detection scope. The right choice turns on the M365 E5 entitlement already in place, the SOC maturity, and the MDR scope. This is the buyer side reference for 2026.
The three major endpoint detection and response platforms in 2026 are Crowdstrike Falcon, Sentinelone Singularity, and Microsoft Defender for Endpoint XDR. All three cover the core EDR scope of behavioral detection, threat hunting, automated investigation, and response. They diverge on price, threat intelligence depth, native integration with the wider security stack, and managed detection service quality.
The right platform turns on three inputs: the Microsoft 365 E5 entitlement already in place, the SOC operational maturity, and the appetite for vendor consolidation versus best of breed.
Pair this guide with the Defender P1 versus P2 reference, the M365 E3 versus E5 versus F3 guide, the Crowdstrike negotiation playbook, the Microsoft knowledge hub, and the Microsoft advisory practice.
The figures and terms here track primary vendor and regulator sources rather than reseller commentary: CrowdStrike bundles, SentinelOne platform, Microsoft Defender for Endpoint, Microsoft 365 plans, and MITRE ATT&CK Evaluations.
Crowdstrike Falcon is the cloud native EDR platform from Crowdstrike. The platform is sold as a modular set of Falcon SKUs, each addressing a security domain. Falcon Insight for EDR. Falcon Prevent for NGAV. Falcon Identity Threat Protection for identity. Falcon Cloud Security for CWPP.
Falcon LogScale for SIEM. The bundle approach allows the customer to start with EDR and expand into XDR and SIEM over time. Crowdstrike holds the strongest threat intelligence brand with Falcon Intelligence and the Overwatch managed threat hunting service.
Sentinelone Singularity is the AI led EDR platform from Sentinelone. The platform combines Static AI on the agent for offline detection with the Singularity Data Lake in the cloud for retrospective hunting. The platform is sold across Core, Control, Complete, and Commercial tiers, with Purple AI as the generative AI add on for natural language threat hunting.
Sentinelone holds the strongest brand in autonomous response. The Storyline graph view sets the visual investigation benchmark.
Microsoft Defender for Endpoint is the cloud native EDR platform from Microsoft. The platform is sold across Plan 1 and Plan 2 tiers. Plan 1 covers core NGAV plus baseline EDR. Plan 2 adds the full EDR feature set, automated investigation, threat hunting, and threat intelligence.
The platform is included in Microsoft 365 E5 and is bundled as the Microsoft Defender XDR umbrella alongside Defender for Identity, Defender for Cloud Apps, and Defender for Office 365.
Microsoft holds the strongest integration story with the wider Microsoft 365 estate and Microsoft Sentinel for SIEM.

|---|---|---|---|
| Behavioral EDR | Yes | Yes | Yes |
| NGAV (Next Gen Antivirus) | Yes (Falcon Prevent) | Yes (built in) | Yes (built in) |
| Threat hunting | Falcon Insight + Overwatch | Storyline + Purple AI | Advanced Hunting (KQL) |

| MDR service | Falcon Complete | Vigilance Respond | Defender Experts for XDR |
| Mac and Linux support | Yes | Yes | Yes (Linux GA 2024) |
List pricing varies by tier, deal size, and bundle scope. The benchmark bands below cover the buyer side benchmark across the Redress engagement base for 2026.
| Tier | Crowdstrike | Sentinelone | Defender |
|---|---|---|---|
| Entry NGAV only | Falcon Go at $4.99 | Singularity Core at $6 to $8 | Defender P1 at $3 (bundled with M365 E3) |
| Standard EDR | Falcon Pro at $8 to $12 | Singularity Control at $10 to $14 | Defender P2 at $5.20 standalone |
| Advanced EDR + threat intel | Falcon Enterprise at $14 to $18 | Singularity Complete at $14 to $18 | Defender XDR (E5 only) |
| Full MDR managed | Falcon Complete at $20 to $35 | Vigilance Respond at $18 to $32 | Defender Experts at $14 to $22 |
| Bundled with Microsoft 365 E5 | n/a | n/a | Included in E5 at $57 per user per month |
Defender for Endpoint P2 is included in Microsoft 365 E5. Organizations already on E5 carry the EDR scope at zero marginal cost. The buyer side decision is whether the broader Defender XDR set (Endpoint, Identity, Office 365, Cloud Apps) is good enough or whether the threat intelligence and MDR quality of Crowdstrike or Sentinelone justifies the third party add on.
The break even math typically favors keeping Defender for the majority of the endpoint population and adding Crowdstrike or Sentinelone only for the high value workload protection scope.
The TCO comparison covers the EDR license, the SOC operations team or the MDR service, the integration cost, and the response tooling. The bands below cover the recurring annual cost for a comparable EDR scope at typical enterprise discount.
| Scenario | License annual | MDR or SOC annual | Three year total |
|---|---|---|---|
| Defender (M365 E5 already in place) | $0 incremental | $0 to $1.5M MDR | $0 to $4.5M |
| Crowdstrike Falcon Enterprise self managed | $1.0M to $1.5M | Internal SOC | $3.0M to $4.5M plus SOC |
| Crowdstrike Falcon Complete | $2.0M to $3.5M | Included in MDR | $6.0M to $10.5M |
| Sentinelone Complete self managed | $1.2M to $1.6M | Internal SOC | $3.6M to $4.8M plus SOC |
| Sentinelone Vigilance Respond | $2.0M to $3.2M | Included in MDR | $6.0M to $9.6M |
MDR is the differentiator at scale. The 24x7 SOC capability the three platforms ship transforms the operations model. The right MDR choice depends on the internal SOC maturity and the incident response volume.
The EDR review compared the Crowdstrike Complete renewal at four point two million dollars per year against the Defender XDR equivalent at zero incremental on the existing M365 E5 plus Microsoft Defender Experts at one point eight million per year. The vendor consolidation saved two point four million per year with no measurable reduction in detection coverage.
The common advice is to buy the EDR with the best independent test scores and treat price as secondary. We disagree. In roughly 30 to 40 selections we advised, accounts that already held Microsoft 365 E5 were paying twice for capability they owned, because Defender for Endpoint P2 was already in the bundle. The buyer side move is to run the E5 entitlement check first, then scope a credible alternative to pull 15 to 30 percent off any incumbent renewal. The best score on paper is not the best deal on the invoice.
Microsoft Defender for Endpoint P2 has the lowest standalone list price at 5.20 US dollars per device per month. Sentinelone Singularity Core lists at 6 to 8 dollars per endpoint per month. Crowdstrike Falcon Go lists at 4.99 per endpoint per month but at the lower feature tier. The Defender advantage compounds when bundled with Microsoft 365 E5.
Defender for Endpoint P2 matches Crowdstrike Falcon Insight at the core EDR feature level in 2026. Both deliver behavioral detection, threat hunting, automated investigation, and response. Crowdstrike holds the advantage in threat intelligence quality and 24x7 managed detection. Defender holds the advantage in price and Microsoft 365 integration.
Purple AI is the Sentinelone generative AI threat hunting assistant. The Purple AI add on lets analysts query the Singularity Data Lake in natural language and automate investigation steps. The add on costs additional per endpoint per month and is the strategic differentiator Sentinelone leads with in enterprise deals through 2026.
Yes for the majority of mid market and many enterprise scopes. Microsoft 365 E5 includes Defender for Endpoint P2 plus Defender for Identity, Defender for Office 365 P2, and Defender for Cloud Apps. The integrated XDR scope often replaces third party EDR plus three or four adjacent tools. The math depends on the E5 license count already in place.
Crowdstrike Falcon Complete, Sentinelone Vigilance Respond, and Microsoft Defender Experts are the three managed detection and response service tiers from the platform vendors. The MDR service typically doubles the per endpoint cost but transfers the 24x7 SOC burden to the vendor. The right choice depends on internal SOC capacity and incident response maturity.
