CrowdStrike vs Microsoft Defender in 2026: Prices, Detection Rates and the SKU Mismatch Buyers Miss

CrowdStrike vs Microsoft Defender is not one comparison

Most articles on this topic compare a product called “CrowdStrike” against a product called “Microsoft Defender.” Neither of those products exists. Both names cover a ladder of licences with very different capabilities, and the single most expensive mistake buyers make is comparing a tier from one ladder against a non-matching tier from the other.

Here is the detail that breaks most comparisons: CrowdStrike Falcon Pro does not include EDR. Read CrowdStrike’s own bundle comparison and you will see Endpoint Detection and Response listed with no description under Go and Pro, and described in full only under Enterprise. Go and Pro are next-gen antivirus with device control, mobile protection, and (on Pro) firewall management. If you buy Falcon Pro believing you bought EDR, you did not.

Microsoft has the mirror-image problem in reverse. Defender for Business — the SMB SKU — does include EDR, automated investigation and response, and vulnerability management, while Defender for Endpoint Plan 1, the enterprise entry SKU, does not. Microsoft’s own Defender for Business FAQ is explicit that Plan 1 covers next-generation protection and attack surface reduction, and that EDR, automated investigation, threat hunting, and six months of data retention arrive with Plan 2.

So the SMB product outranks the enterprise entry product on EDR. Lining the two ladders up by capability rather than by marketing tier gives you this:

Notice the gap in the CrowdStrike column. There is no CrowdStrike tier that sits where Defender for Business sits — real EDR without the full enterprise price and operational weight. That gap is the entire commercial story of this comparison at the small end of the market, and it is why the two vendors so often lose to each other for reasons that have nothing to do with detection quality.

CrowdStrike vs Microsoft Defender pricing in 2026

Both vendors publish list pricing, so this part is verifiable rather than estimated. What is not obvious from the price pages is that the two vendors do not price the same unit. CrowdStrike charges per device. Microsoft charges per user, and a Defender for Endpoint user licence covers up to five devices — a figure Microsoft states directly in the FAQ on its Defender pricing page. Neither vendor includes servers in those counts.

That single difference in billing unit moves the comparison more than any feature does. A 60-person firm where everyone has a laptop and a desk machine is 120 billable endpoints to CrowdStrike and 60 billable seats to Microsoft.

CrowdStrike Falcon list pricing

The 100-device ceiling on Falcon Go is a footnote on CrowdStrike’s pricing page, not a headline, and it catches growing companies who budgeted at the $59.99 rate. Crossing 100 devices means a bundle change, not just a bigger invoice.

Microsoft Defender list pricing

One practical note that trips people up in procurement: as of this writing Microsoft does not publish standalone Defender for Endpoint Plan 1 and Plan 2 prices on its main security pricing pages. Plan 2 reaches most buyers inside Microsoft 365 E5, inside the $12 Microsoft Defender Suite add-on for E3 tenants, or through a reseller quote. If a comparison article quotes you a crisp per-device figure for Plan 2, ask where it came from.

The headline gap is stark. Defender for Business at $3.00 per user per month is $36 per user per year, covering up to five devices. Falcon Enterprise is $184.99 per device per year. Both include EDR. That is not a rounding difference — it is the reason Microsoft wins so many SMB evaluations on paper before anyone opens a console.

Detection rates: what the 2026 test data actually shows

This is where the topic gets misreported hardest, so start with the fact that reframes everything else: there is no current head-to-head MITRE ATT&CK result for these two vendors.

In June 2025 Microsoft announced it would not participate in MITRE ATT&CK Evaluations: Enterprise 2025, saying the decision let it concentrate resources on the Secure Future Initiative and product development. SentinelOne and Palo Alto Networks followed in September. Infosecurity Magazine’s reporting put the participant count for that round at roughly a dozen, down from 19 the year before and 30 in 2022.

CrowdStrike’s widely quoted 100% detection, 100% protection, zero false positives result comes from that 2025 round — a round Microsoft was not in. It is a real result against genuinely hard tradecraft, including MITRE’s first cloud adversary emulation and a newly added Reconnaissance tactic. It is not a win over Defender, because Defender was not on the field. Forrester analyst Allie Mellen has also publicly cautioned that vendor claims of 100% deserve scrutiny, since they can reflect selective reporting or test configurations no one would run in production.

The one current head-to-head: AV-Comparatives H1 2026

The most recent independent test containing both vendors is the AV-Comparatives Business Security Test for March–June 2026, published 15 July 2026. It ran on Windows 11 with 400 real-world test cases. The results do not follow the script most buyers expect:

CrowdStrike took the malware protection test by 0.4 points. Microsoft took real-world protection by 0.3 points with a clean false-alarm sheet, and had roughly half the measured system impact. AV-Comparatives explicitly listed CrowdStrike among the vendors with above-average false positives on non-business software in that round.

Now the caveats that make this data useful rather than misleading, because they are the part nobody quotes:

• The products are not equivalent. AV-Comparatives tested “Microsoft Defender Antivirus with MEM” against “CrowdStrike Falcon Enterprise.” That is Microsoft’s prevention layer against CrowdStrike’s full EDR platform. It measures whether malware got blocked, not whether an analyst could reconstruct an intrusion afterwards.
• The configurations are not equivalent. Vendors configure their own products for these tests. CrowdStrike ran everything enabled at “Extra Aggressive,” with early-adopter sensor builds and every detection playbook on. Microsoft ran near-default with a longer cloud timeout and sample submission enabled. The false-positive spread is at least partly a consequence of that choice.
• Prevention rates converge at the top; response capability does not. Six vendors landed within 1.3 points of each other on real-world protection. The meaningful differences between these platforms live in hunting, retention, and investigation — which this test does not measure.

The honest summary: on raw blocking of commodity threats in 2026, these two are inside the margin of error of each other, and Microsoft’s false-positive and performance numbers are better. On deep detection against targeted adversaries, CrowdStrike has the stronger published record, but no current test puts the two in the same room to prove it.

Total cost of ownership beyond the licence line

Licence price is the smallest line in an EDR budget above about 200 endpoints. These are the costs that decide the real number, and they cut in opposite directions for the two vendors.

Two asymmetries matter more than the rest.

First, Microsoft’s cost is frequently negative at the margin. If a tenant already runs Microsoft 365 E5, Defender for Endpoint Plan 2 is already paid for. Adding CrowdStrike on top is entirely incremental spend for capability the organisation already licenses. That is a hard argument to beat in a budget review, and it is Microsoft’s single strongest commercial position in this market.

Second, Microsoft’s capability is only as deep as the weakest licence in the tenant. Buy Defender for Business and you get EDR but not advanced hunting or the full device timeline — you see the alert story Microsoft chooses to present, and you cannot query the raw telemetry behind it. During a real incident, that limit is discovered at the worst possible moment. CrowdStrike’s Enterprise tier gives every customer the same investigation surface regardless of what else they buy.

Concentration risk belongs in this section too, honestly and in both directions. On 19 July 2024 a faulty Falcon sensor content update caused blue screens on roughly 8.5 million Windows machines — a configuration failure, not a breach. CrowdStrike has since shipped staged rollout and content update controls, and any serious evaluation should confirm those controls are enabled rather than assume it. The Microsoft-side equivalent is different in shape but real: consolidating endpoint, identity, email and SIEM on one vendor means one vendor’s outage or compromise touches all of them at once.

CrowdStrike vs Microsoft Defender for small business

Below roughly 300 users, the comparison is Defender for Business against Falcon Go or Falcon Pro, and it is not close on value.

Defender for Business at $3.00 per user per month includes next-generation protection, attack surface reduction, web content filtering, EDR, automated investigation and remediation, and vulnerability management, across Windows, macOS, iOS and Android. Falcon Go at $59.99 per device per year includes antivirus, device control and mobile protection — and no EDR. Falcon Pro at $99.99 adds firewall management and still no EDR.

So for a small business, the cheapest CrowdStrike path to actual EDR is Falcon Enterprise at $184.99 per device per year. That is roughly five times the annual cost of Defender for Business per seat, before accounting for Microsoft’s five-devices-per-user allowance.

Three constraints keep this from being a clean sweep, and all three are worth checking before you commit:

• Defender for Business does not support mixed licensing within a tenant — Microsoft states this directly in its FAQ. You cannot run some seats on Defender for Business and some on Plan 2 and expect it to behave.
• Servers need the separate add-on. User licences do not confer server rights, and the server add-on carries its own per-subscription limit. A shop with a meaningful server estate should price that line explicitly rather than assume coverage.
• No advanced hunting. If your incident response plan involves querying raw endpoint telemetry, Defender for Business will not do it, and the upgrade path is Plan 2 via E5 or the Defender Suite add-on.

The realistic small-business recommendation: if you are already on Microsoft 365, start with Defender for Business or Business Premium and put the difference into a managed detection service. Buying Falcon Go instead of Defender for Business is paying more for less — you are giving up EDR to gain nothing.

The 50-endpoint math, both ways

Fifty endpoints is the size where this question gets asked most often, so here is the arithmetic at list price. Assume a 50-person Windows-centric company on Microsoft 365 Business Standard, no dedicated security operations staff, servers excluded from both columns.

Comparing like with like — the two options that actually include EDR — Defender for Business costs $1,800 a year and Falcon Enterprise costs $9,249.50. That is 5.1x.

Now change one assumption. Give those 50 people a laptop and a desk machine, so 75 devices. Microsoft stays at $1,800, because you are still buying 50 user licences and 75 is under the 250-device allowance. CrowdStrike goes to 75 × $184.99 = $13,874.25. The ratio moves to 7.7x, and nothing about the security posture changed — only the billing unit did.

What the extra spend buys, stated fairly: Falcon Enterprise includes Adversary OverWatch, CrowdStrike’s 24/7 managed threat hunting. Defender for Business includes no managed hunting and no advanced hunting at all. To reach comparable coverage on the Microsoft side you would move to Plan 2 — via E5 at $60 per user per month, or the $12 Defender Suite add-on on an E3 tenant — and add Defender Experts. At that point the gap narrows sharply and the decision stops being about price.

Which means the real 50-endpoint question is not “which is cheaper.” It is: do we have anyone who will read an EDR alert at 2am? If the answer is no, $1,800 on Defender for Business plus a managed detection provider beats $9,249 on a platform nobody is watching. If the answer is yes and that person is a competent analyst, the extra investigation depth starts earning its cost.

CrowdStrike vs Microsoft Defender for MSPs

For managed service providers the comparison inverts, because the constraint is not price per endpoint. It is uniformity across a client book.

Both vendors support multi-tenant operation. CrowdStrike offers Falcon Flight Control, a parent console that pushes policy into segregated child tenants, plus Falcon Complete for Service Providers for partners reselling managed response. Microsoft routes MSPs through the Cloud Solution Provider programme and Microsoft 365 Lighthouse, which Microsoft names in its own SMB security FAQ as the central place to manage customers across Business Basic, Standard, Premium, Defender for Business and the enterprise SKUs.

The structural difference is what each model does to your service delivery:

That first row is the whole argument. On Microsoft, a client on Business Premium gets EDR without advanced hunting; a client on E5 gets full Plan 2; a client on Business Standard gets essentially nothing until you sell them an upgrade. Your runbooks, your alert triage and your reporting have to branch per tenant, and the branch you forget is the client you cannot investigate properly during an incident. CrowdStrike removes that variability at the cost of a line item every client can see on their invoice.

The practical pattern that works: standardise security-led clients on one platform and let the licensing-led clients ride their existing Microsoft entitlements, but never pretend the two tiers of client get the same service. Where this gets operationally painful is reporting — producing consistent monthly security summaries across tenants with different data models is a data-pipeline problem, not a security one, and it is the kind of work worth handing to an automation build rather than absorbing into analyst hours.

Which is better? Four questions that decide it

There is no general answer, and any article that gives you one is selling something. There are four questions whose answers determine the outcome in almost every evaluation.

Beyond that, three judgements worth stating plainly:

• Do not buy Falcon Go or Falcon Pro as an EDR product. They are not one. If the requirement is EDR, the CrowdStrike answer is Enterprise and the budget is $184.99 per device per year.
• Do not treat “Defender is free” as true. The antivirus built into Windows is free. Everything a security team actually needs — central management, EDR, retention, hunting — is a paid SKU, and the useful ones start at $3.00 per user per month and climb to $60.
• Weight false positives properly. The 2026 AV-Comparatives data shows Microsoft with zero real-world false alarms against CrowdStrike’s eight, at near-identical protection rates. For a small team, alert fatigue is a more likely cause of a missed breach than a 0.3-point detection gap.

Run a proof of concept on your own fleet before committing either way. Both vendors offer trials — CrowdStrike a 15-day Falcon trial with a 30-day refund window, Microsoft a 30-day Defender for Business trial — and a fortnight of real telemetry from your own environment will tell you more than every comparison table on the internet, including this one.

If the endpoint decision is one piece of a broader technology review and you are not sure which problem to solve first, tell us what you are working with and we will point you at the right scope.
