Most CrowdStrike-versus-Defender comparisons compare the wrong things: a CrowdStrike entry tier that has no EDR in it against a Microsoft plan that does, or a marketing claim about detection quality against a benchmark neither vendor actually lost. This comparison uses two sources and nothing else — the vendors' own published pricing and documentation, and SE Labs' independent enterprise endpoint tests from 2026.
The short version: on prevention quality these two are close enough that it should rarely decide the purchase. What should decide it is tier structure, licensing model, and what you already own.
Every price below is a list price read from the vendor's published pricing page in August 2026. Actual pricing varies with term, seat count, partner discount and negotiation.
What each tier actually includes
This is the single most misread part of the comparison. Both vendors sell an entry tier without EDR, and both sell EDR a tier up.
| CrowdStrike | Microsoft | |
|---|---|---|
| Entry tier, no EDR | Falcon Go — $59.99/device/year. NGAV, device control, mobile device protection, Express Support. Max 100 devices. | Defender for Endpoint Plan 1 — next-gen protection, manual response actions, attack surface reduction, central management. Included in Microsoft 365 E3. |
| Middle tier | Falcon Pro — $99.99/device/year. Adds firewall management. | (no direct equivalent) |
| EDR tier | Falcon Enterprise — $184.99/device/year. Adds EDR, threat intelligence and hunting. | Defender for Endpoint Plan 2 — adds EDR, automated investigation and remediation, threat and vulnerability management, threat analytics, deep analysis sandbox, Microsoft Threat Experts, six months data retention. Included in Microsoft 365 E5. |
| SMB bundle | (no separate SMB SKU) | Defender for Business — $3.00/user/month paid yearly. Includes EDR, next-gen AV, vulnerability management, automated investigation and remediation, ASR. Up to 300 users, up to 5 devices per user. |
| Managed service | Falcon Complete Next-Gen MDR — quote only. Includes Breach Prevention Warranty. | Defender Experts for XDR — quote only. |
Two consequences fall out of that table.
Falcon Go is not an EDR product. If your requirement is endpoint detection and response — because a customer security questionnaire, a cyber insurance application, or an auditor asked for it — the CrowdStrike line item is $184.99 per device per year, not $59.99. Comparisons that quote Falcon Go's price alongside Defender for Endpoint Plan 2's capability set are comparing an antivirus to an EDR.
Defender for Business is the outlier on price-per-capability. At $3.00 per user per month paid yearly, covering up to five devices per user, with EDR and automated investigation included, it has no direct CrowdStrike counterpart. For a 50-person business where most people have a laptop and a phone, that is roughly $1,800 a year. Falcon Enterprise across 50 devices at list is roughly $9,250. That gap is real and it is the reason a lot of SMBs never seriously evaluate CrowdStrike.
The counterweight is that Defender for Business caps at 300 users, and that Microsoft's per-user model rewards organisations with few devices per person while CrowdStrike's per-device model is indifferent to how you allocate them.
Independent test results: closer than the marketing suggests
SE Labs runs a quarterly Enterprise Endpoint Security (Protection) evaluation that includes both products, using the same threats against every participant across a full attack chain. Two rounds are available for 2026.
April–June 2026 (published July 2026):
| Product | Protection Accuracy | Legitimate Accuracy | Total Accuracy | Award |
|---|---|---|---|---|
| CrowdStrike Falcon | 100% | 100% | 100% | AAA |
| Microsoft Defender Antivirus (enterprise) | 96% | 100% | 99% | AAA |
In the underlying detail, CrowdStrike blocked 100 of 100 threats and was compromised zero times. Microsoft blocked 98 and was compromised twice.
January–March 2026:
| Product | Protection Accuracy | Legitimate Accuracy | Total Accuracy | Award |
|---|---|---|---|---|
| CrowdStrike Falcon | 100% | 100% | 100% | AAA |
| Microsoft Defender Antivirus (enterprise) | 100% | 100% | 100% | AAA |
Here they tied outright. Microsoft blocked 100 of 100 threats outright; CrowdStrike blocked 99 and neutralised the remaining one after it began executing. Neither was compromised.
Three things are worth drawing out of this, because they cut against claims made in a lot of comparison content — including, until this update, ours.
Both products scored 100% Legitimate Accuracy in both rounds. Neither misclassified a single legitimate application or website. The widely repeated claim that Microsoft Defender generates materially more false positives than CrowdStrike is not supported by these results. SE Labs' April–June report states flatly that "all of the products allowed all legitimate applications and websites."
CrowdStrike's edge in the most recent round is real but narrow. Two compromises out of 100 against zero is a genuine difference and worth weighing if you are a high-value target. It is not the difference between protected and unprotected, and it reversed direction between quarters.
Scope caveat, and it is an important one. SE Labs tests "Microsoft Defender Antivirus (enterprise)" — the prevention engine — not the full Defender for Endpoint Plan 2 stack with EDR, automated investigation and remediation, and threat hunting layered on. It is a prevention comparison, not an EDR comparison. Treat it as evidence about how each product stops threats at the endpoint, not as a verdict on detection-and-response workflow quality, which no public benchmark cleanly measures.
If you want to weigh managed-service options rather than software tiers, our MDR vendor selector compares Falcon Complete against Arctic Wolf, Sophos MDR, Red Canary, Expel, Huntress and others on coverage and response model.
Platform coverage
Microsoft's minimum requirements documentation lists Defender for Endpoint support for Windows 10 and 11, Windows Server 2012 R2 and later, Mac, Linux, Windows Subsystem for Linux, Android and iOS. The "Defender is Windows-only" objection is out of date, though Microsoft publishes a separate supported-capabilities-by-platform matrix because parity across those platforms is not identical — check it against the specific controls you need rather than assuming a capability travels.
CrowdStrike delivers Falcon as a single cloud-managed agent across its supported platforms, which is a genuine operational simplification if you run a heterogeneous fleet and want one console and one deployment mechanism.
The server licensing trap. Microsoft's documentation states that Defender for Endpoint Plan 1 and Plan 2 do not include server licenses. Onboarding servers requires Microsoft Defender for Servers Plan 1 or Plan 2 (through Defender for Cloud), Microsoft Defender for Endpoint Server, or Microsoft Defender for Business servers. CrowdStrike prices per device without that distinction. If you have a meaningful server estate, model both totals before concluding Microsoft is cheaper — this is the line item that most often closes the gap.
Operational reality
Neither vendor's documentation settles deployment effort, so treat what follows as engineering judgment rather than sourced fact.
Defender for Endpoint's configuration surface is large. Attack surface reduction rules, controlled folder access, web content filtering, network protection and application control are each independently configurable, typically through Intune or Group Policy, and the defaults are conservative. That flexibility is an asset if you have someone to use it and a cost if you do not. Falcon's policy model is narrower and opinionated, which shortens time-to-value and lengthens the list of things you cannot change.
The corollary: Defender's value rises sharply when the rest of the Microsoft security stack is in play. Signals shared with Defender for Office 365, Defender for Identity and Entra ID conditional access produce correlation that a standalone endpoint agent cannot replicate. If you are on E5, you have already bought that correlation, and running a second endpoint agent alongside it duplicates spend rather than adding a layer.
Running Falcon does not require removing Microsoft Defender Antivirus — Microsoft's documentation notes that when Defender Antivirus is not the active anti-malware solution it moves to passive mode — but you should be deliberate about which product is authoritative rather than discovering it during an incident.
Who should pick which
Choose Microsoft Defender for Endpoint / for Business if:
- You already hold Microsoft 365 E5 (Plan 2 is included) or Business Premium (Defender for Business is included). Buying a second endpoint product on top is duplicate spend that needs a specific justification.
- You have fewer than 300 users, several devices per person, and want EDR at the lowest defensible cost — Defender for Business is hard to beat at $3.00 per user per month.
- Your security operations already live in the Microsoft Defender portal and you want endpoint signal correlated with identity and email signal.
- You have someone who can configure ASR rules and tune policy, or a partner who will.
Choose CrowdStrike Falcon if:
- You need EDR and are willing to pay for Falcon Enterprise at $184.99 per device per year to get a narrower, faster-to-deploy configuration surface.
- You run a genuinely mixed fleet and want one agent, one console and one vendor relationship without mapping Microsoft's per-platform capability matrix.
- You want a managed option — Falcon Complete Next-Gen MDR — from the same vendor as the agent, and the Breach Prevention Warranty carries weight in your risk conversation.
- You are a high-value target where a two-in-a-hundred difference in a quarterly prevention test is worth paying for.
- You are deliberately avoiding vendor concentration risk in Microsoft.
It probably does not matter much if: you are a small Windows-centric business with a competent managed provider, no EDR requirement in writing, and no Microsoft 365 licence above Business Standard. Both products will stop what you are likely to encounter. Choose on price and on who supports it.
What we would actually check before signing
- Pull your current Microsoft licence position first. If E5 or Business Premium is already in place, the incremental cost of Microsoft is zero and CrowdStrike has to justify its full price, not its price difference.
- Count servers separately. Microsoft licenses them apart from Plan 1 and Plan 2. This is where per-endpoint comparisons most often mislead.
- Get the requirement in writing. "EDR" in a customer questionnaire or insurance application rules out Falcon Go and Defender for Endpoint Plan 1 entirely, and changes which prices you should be comparing.
- Trial both. CrowdStrike publishes a 15-day free trial with no credit card required; Microsoft offers trials through the Defender portal. Prevention scores are near-identical, so the deciding factor will be console workflow and alert quality in your environment, which no benchmark can tell you.
- Ask for the managed-service quote early. Both Falcon Complete and Defender Experts for XDR are quote-only and can change the total materially.
If you are not yet sure which controls you need at all, our cybersecurity maturity assessment will size the gap before you shortlist products. If you have already chosen Falcon and are deploying it, the CrowdStrike Falcon command reference covers sensor installation, troubleshooting and policy operations.
If your question is broader than these two products — whether you need EDR, MDR, XDR, an MSSP or a co-managed SIEM at all — start with our cybersecurity service selector instead, and see choosing between MDR, EDR, MSSP, XDR and SOC.
