CrowdStrike vs SentinelOne vs Microsoft Defender: Real AI Endpoint Security Cost per Device
Short answer
CrowdStrike and SentinelOne both publish real, checkable self-serve tier pricing — a rarity in enterprise security software — and at their top public tiers they land within about $5 per device per year of each other, despite SentinelOne's broader reputation for being 50–67% cheaper than CrowdStrike at lower tiers. Microsoft Defender's story is completely different: for any organization already licensed for Microsoft 365 E5 or Business Premium, its full EDR capability (Defender for Endpoint Plan 2, or Defender for Business) is bundled in at zero incremental cost — making it, in practice, the industry's most effective price-negotiation lever against both CrowdStrike and SentinelOne, not just a budget alternative.
Pricing at a glance
| CrowdStrike Falcon | SentinelOne Singularity | Microsoft Defender | |
|---|---|---|---|
| Entry tier | Falcon Go: $59.99/device/year, prevention-only, capped at 100 devices | Singularity Core: ~$69.99/device/year, basic endpoint protection | Defender for Endpoint Plan 1: ~$3.00/user/month (~$36/year) — a per-user license, not a confirmed per-device rate; see note below on why this isn't directly comparable to the device-based figures in this row |
| Lowest tier with full EDR/XDR | Falcon Pro: $99.99/device/year (adds host firewall management) | Singularity Control: ~$79.99/device/year (adds device control, firewall, app inventory) — full EDR arrives at Singularity Complete, ~$159.99/device/year | Defender for Endpoint Plan 2: full EDR platform, not basic antivirus — standalone per-device price not officially published |
| Top public tier | Falcon Enterprise: $184.99/device/year (adds Falcon Insight XDR + Falcon OverWatch 24/7 managed threat hunting) | Singularity Enterprise/Commercial: ~$179.99–209.99/device/year depending on source | Bundled into Microsoft 365 E5 or Business Premium at zero incremental cost |
| Fully managed MDR | Falcon Complete: custom-quoted, reported $200–400/device/year at 1,000-endpoint scale | Not confirmed in available sources | Not applicable in the same form |
| Flexible/enterprise licensing | Falcon Flex: quote-based, reportedly most useful above ~2,000 endpoints for shifting spend across modules | Not confirmed | N/A |
| Volume discount behavior | Reportedly begins around 500 endpoints (10–15% off list); negotiated enterprise rates reported as low as $11–50/device/year at scale | Reported to price within 10–15% of CrowdStrike at negotiated enterprise volume | N/A — already zero incremental for E5/Business Premium customers |
A genuinely important nuance about the "SentinelOne is cheaper" reputation: multiple sources describe SentinelOne as pricing 50–67% below CrowdStrike generally, which is true at entry and mid tiers. But at the top public tier — the one with genuinely comparable full-XDR capability — CrowdStrike Falcon Enterprise ($184.99/device/year) and SentinelOne's equivalent tier ($179.99/device/year, per one source) price within about $5/device/year of each other. The two vendors converge sharply once you compare equivalent capability rather than headline entry prices.
What headline pricing excludes
Microsoft licenses Defender for Endpoint Plan 1 per user, not per device — a genuinely different billing unit than CrowdStrike's and SentinelOne's per-device pricing, and this article does not treat the two as interchangeable. A single licensed user can legitimately cover multiple devices under Microsoft's own licensing terms in some scenarios, which means multiplying a device count directly by the $3.00/user/month rate — as this article's 25-endpoint scenario does, for illustration — relies on an explicit, stated assumption that each device maps to exactly one licensed user. Where that assumption doesn't hold (a user with a laptop and a phone, for instance, both needing protection under one license), the real per-device economics of Plan 1 would differ from a simple per-device multiplication.
Microsoft doesn't publish official standalone per-device pricing for Defender for Endpoint Plan 2 at all. A commonly cited $62.40/device/year figure circulates in third-party comparisons, but it's explicitly an unverifiable estimate, not a Microsoft-published rate — because Microsoft's actual go-to-market for full EDR capability is almost entirely through E5 or Business Premium bundling, not standalone sale.
CrowdStrike's list prices are genuinely just the starting point for full-EDR tiers. Marketplace and reseller data puts the real, fully-loaded per-endpoint total cost of ownership — once managed services and add-on modules are included — at $200–400 per endpoint per year for mid-market deployments at roughly 1,000-endpoint scale, well above the $184.99 Falcon Enterprise list price alone.
SentinelOne's tier names and prices show some genuine variance across sources — one source uses "Complete" and "Commercial" as the top two tiers ($159.99 and $209.99/device/year respectively), while another uses "Enterprise" at $179.99/device/year for what appears to be a comparable capability level. This article presents both rather than picking one as definitively correct.
Hidden costs
- Server endpoints typically cost 1.5–2x the workstation rate on CrowdStrike specifically — a company with a meaningful server fleet alongside its workstations should budget accordingly rather than assuming a flat per-device rate across the whole environment.
- CrowdStrike's Falcon Complete managed detection and response service is a completely separate, custom-quoted cost layer on top of the base Falcon platform — reported at $200–400/device/year at 1,000-endpoint scale, this can roughly double or triple the effective per-device cost versus self-managed Falcon Enterprise alone.
- The single most powerful negotiating lever against both CrowdStrike and SentinelOne is a genuine Microsoft Defender E5 comparison — multiple sources describe CrowdStrike as viewing Microsoft as a category-level competitive threat (not just another vendor), meaning a credible E5-bundling comparison during negotiation reportedly unlocks larger discounts (30–45% off list) than a SentinelOne-vs-CrowdStrike comparison alone would.
Worked scenarios
25 endpoints (small business)
| Estimated annual cost | |
|---|---|
| CrowdStrike Falcon Go | 25 × $59.99 = $1,499.75/year (comfortably under the 100-device cap) |
| SentinelOne Singularity Core | 25 × $69.99 = $1,749.75/year |
| Microsoft Defender for Business (bundled in Microsoft 365 Business Premium) | $0 incremental if already on Business Premium. A standalone Defender for Endpoint Plan 1 comparison is possible only under an explicit assumption: if each of the 25 devices corresponds to exactly one licensed user, 25 × $3.00 × 12 = $900/year — but Plan 1 is licensed per user, not per device, so this figure should be read as a per-user-license cost applied under a stated 1-user-to-1-device assumption, not a confirmed per-device rate |
At small-business scale, a company already on Microsoft 365 Business Premium gets meaningful endpoint protection at zero additional software cost — a real, quantifiable advantage that a pure CrowdStrike-vs-SentinelOne price comparison would miss entirely.
250 endpoints (mid-size company)
| Estimated annual cost | |
|---|---|
| CrowdStrike Falcon Pro (lowest full-EDR tier) | 250 × $99.99 = $24,997.50/year |
| CrowdStrike Falcon Enterprise (adds managed threat hunting) | 250 × $184.99 = $46,247.50/year |
| SentinelOne Singularity Complete | 250 × $159.99 = $39,997.50/year |
| Microsoft Defender for Endpoint Plan 2 (standalone, unverified estimate) | 250 × $62.40 = ~$15,600/year (explicitly an unverified third-party estimate, not a Microsoft-published rate); $0 incremental if already on Microsoft 365 E5 |
At this scale, the gap between CrowdStrike's entry full-EDR tier (Falcon Pro) and its top tier (Falcon Enterprise) is nearly double — a company should carefully evaluate whether it actually needs Falcon Insight XDR and 24/7 managed threat hunting, or whether Falcon Pro's lighter feature set is sufficient, before defaulting to the top tier.
2,500 endpoints (enterprise)
| Estimated annual cost | |
|---|---|
| CrowdStrike Falcon Enterprise (list price) | 2,500 × $184.99 = $462,475/year |
| CrowdStrike Falcon Enterprise (reported negotiated enterprise rate, midpoint ~$30/device) | 2,500 × $30 ≈ $75,000/year — illustrating how dramatically negotiated pricing can diverge from list at this scale |
| CrowdStrike Falcon Complete (fully managed, at the reported 1,000-endpoint reference rate, scaled) | 2,500 × $200–400 = $500,000–1,000,000/year |
| SentinelOne (reported negotiated enterprise rate) | Reported to land within 10–15% of CrowdStrike's negotiated rate — roughly $65,000–86,000/year using the same midpoint logic |
| Microsoft Defender for Endpoint Plan 2 | $0 incremental if already on Microsoft 365 E5 — the scenario where this option's advantage is most dramatic in relative terms |
At enterprise scale, the gap between list price and negotiated price is enormous for both CrowdStrike and SentinelOne — an organization evaluating either vendor at 2,500+ endpoints should treat the list price as a starting point for negotiation, not a real budget number, and should specifically use a genuine Microsoft E5 alternative as negotiating leverage given how seriously both vendors reportedly treat that particular competitive threat.
Break-even and crossover
The most useful "crossover" in this category isn't between CrowdStrike and SentinelOne — it's between paying for either of them at all versus using Microsoft Defender capability an organization may already own. Any organization already licensed for Microsoft 365 E5 or Business Premium should treat its Defender for Endpoint Plan 2 (or Defender for Business) capability as a zero-incremental-cost baseline, and evaluate whether CrowdStrike's or SentinelOne's additional capability (managed threat hunting, ransomware rollback, cross-platform depth) justifies paying for a second, fully separate endpoint security product on top of software already being paid for through existing Microsoft licensing.
Who pays more, and when
- A small business already on Microsoft 365 Business Premium gets real endpoint protection at zero incremental software cost — the lowest-friction, cheapest starting point of any option in this article.
- A mid-market company outside the Microsoft ecosystem, or one specifically prioritizing autonomous on-agent AI and ransomware rollback, should compare CrowdStrike Falcon Pro against SentinelOne Singularity Control/Complete directly — the two are closely matched in both price and capability at this tier.
- A large enterprise evaluating either CrowdStrike or SentinelOne should never treat list price as the real number — negotiated enterprise rates are reported to run a fraction of list, and using a credible Microsoft E5 comparison as leverage is reported to be a more effective lever than comparing CrowdStrike and SentinelOne against each other alone.
- An organization specifically needing 24/7 managed threat hunting or fully managed MDR should budget for CrowdStrike Falcon Complete or an equivalent managed-service layer as a separate, substantial cost on top of the base EDR platform — not an incremental add-on to the base per-device price.
Limitations and uncertainty
CrowdStrike's and SentinelOne's list prices for self-serve tiers are reasonably well-corroborated across multiple sources, though SentinelOne's exact top-tier naming and price shows some genuine variance ($159.99–209.99/device/year across different tier names in different sources). Negotiated enterprise pricing for both vendors is reported rather than officially published, and the specific dollar figures used in the 2,500-endpoint scenario above are illustrative midpoints from reported ranges, not confirmed quotes. Microsoft does not publish standalone per-device pricing for Defender for Endpoint Plan 2 at all; the $62.40/device/year figure used in this article is explicitly flagged in its source as a third-party estimate that cannot be verified against any Microsoft-published rate. Separately, Defender for Endpoint Plan 1's confirmed $3.00/user/month rate is a per-user license, not a per-device one — any comparison in this article that applies it against a device count does so under an explicit stated assumption (one user per device), not as a confirmed like-for-like per-device rate.
