A buyer side comparison of CrowdStrike Falcon, SentinelOne Singularity, and Microsoft Defender for Endpoint in 2026. How each platform prices per endpoint, where module bundling and the E5 bundle bite, and how to compare on true cost.
CrowdStrike, SentinelOne, and Microsoft Defender for Endpoint are the three EDR and XDR platforms most often shortlisted, and the licensing model behind each, not the detection demo, decides the true cost per endpoint. Module bundling and platform lock in are where the deals diverge.
This pillar is for security and procurement leaders running an EDR or XDR selection or renewal in 2026. Read it with the CrowdStrike Falcon negotiation guide, the Defender Plan 1 versus Plan 2 guide, and Vendor Shield.
All three price per endpoint per year, but the capability inside the base price is where they split. Read the bundle, not the rate.
CrowdStrike sells discrete modules on the Falcon platform, from base prevention up to identity protection and threat intelligence. The base bundle is narrower than buyers expect. CrowdStrike lists its bundles on its platform bundles page.
SentinelOne tiers Singularity into Core, Control, and Complete, with managed detection and response priced separately. SentinelOne outlines the tiers on its platform page.
Defender for Endpoint comes in Plan 1 and Plan 2, and Plan 2 is bundled into Microsoft 365 E5 and the E5 Security add on. Microsoft documents this on its Defender for Endpoint page.
Normalize to true cost per endpoint per year with the modules you actually need. The base SKU is a poor guide because the capability gaps differ.
EDR and XDR licensing model comparison, illustrative
| Dimension | CrowdStrike | SentinelOne | Defender |
|---|---|---|---|
| Pricing unit | Per endpoint, module | Per endpoint, tier | Per user, bundle |
| Base capability | Prevention | Core EDR | Plan 1 or Plan 2 |
| Add on driver | Module stack | Tier and MDR | E5 bundle |
| Best fit | Security first buyers | Autonomous response | Microsoft E5 estates |
The standard advice is to buy Defender because it is already in your E5 license and looks free. We disagree. In roughly 1 in 3 Microsoft estates we benchmarked, the capability gap forced add ons or a second tool that erased the saving.
The buyer side move is to map the capabilities you actually require, then price all three at that capability level. Free in the bundle is not free if it does not cover the requirement.

The EDR you should buy is the one that meets your real capability requirement at the lowest cost per endpoint, not the one that ships free inside a license you already hold.
There is no single best platform for every estate. The right choice depends on your capability requirement, your existing Microsoft licensing, and your appetite for managed response. Compare on true cost per endpoint at the capability level you actually need.
CrowdStrike sells modules on the Falcon platform, from base prevention up to identity protection, threat intelligence, and managed Falcon Complete. The base bundle is narrower than many buyers expect, so the module stack drives most of the real per endpoint cost.
SentinelOne tiers Singularity into Core, Control, and Complete, with managed detection and response priced separately. Moving from Control to Complete and adding Vigilance managed response are the main cost drivers above the base tier.
Defender for Endpoint Plan 2 is included in Microsoft 365 E5 and the E5 Security add on, so it can appear free if you already own E5. The real question is whether its capability covers your requirement without forcing additional tools or modules.
Plan 1 provides core endpoint protection and response, while Plan 2 adds advanced hunting, automated investigation, and threat and vulnerability management. Plan 2 is the version bundled into E5, and the gap between the two is a frequent source of confusion in cost comparisons.
Add on modules commonly increase the per endpoint price by 40 to 90 percent over the base SKU, depending on the platform and the capabilities selected. This is why the base SKU price is a poor guide to the real cost of a deployment.
Yes. Multi year prepay commitments commonly secure 15 to 30 percent off annual billing, but they reduce flexibility if your endpoint count or requirements change. Weigh the discount against the lock in before committing to a long term.
Keep a credible alternative platform in the evaluation, benchmark your per endpoint price, and price the exact module set you use rather than the vendor bundle. An independent advisor at the table helps secure discounts and caps the sales motion resists.
EDR and XDR pricing benchmarks, module bundling traps, true cost per endpoint, and the buyer side moves across CrowdStrike, SentinelOne, and Microsoft Defender.
Used across more than five hundred enterprise engagements. Independent. Buyer side. Built for procurement leaders running the next renewal cycle.
The standard advice is to buy Defender because it is already in your E5 and looks free. We disagree. In a third of Microsoft estates we benchmarked, the capability gap forced add ons that erased the saving. The buyer side move is to price all three at the capability you actually need.
500+ enterprise clients. 11 vendor practices. Industry recognized. One conversation can change what you pay for the next three years.
One short note on endpoint security pricing moves, EDR and XDR bundling traps, true cost per endpoint, and the buyer side levers we run in client engagements. No noise.
