Best Endpoint Security for Defense Contractors (CMMC) (November 2026)

Executive summary

CMMC and DFARS do not name a product: a small defense supplier handling only Federal Contract Information can address CMMC Level 1's malicious-code practices with a centrally managed endpoint product that scans in real time and updates itself, while a supplier handling Controlled Unclassified Information has a practical reason to run EDR that keeps enough monitoring data to help support DFARS 252.204-7012's 90-day preservation duty. The difference matters now. CMMC Phase 1 began on 10 November 2025, and Phase 2, in which DoD intends to make a third-party Level 2 assessment a condition of award for applicable contracts (it may delay that to an option period), starts one calendar year later, on 10 November 2026 (32 CFR 170.3(e)).

Across 17 tracked products (vendor data as of 2026-11-01), 6 come from vendors that publish CMMC relevance and 3 have vendors holding FedRAMP authorisation. No product makes a company compliant. The product supplies part of the evidence an assessor examines.

This is general information, not legal advice.

What does CMMC Level 1 require of endpoint security?

Level 1 applies the 15 basic safeguarding requirements of FAR 52.204-21. Three are about malicious code, and they read like a specification for business antivirus:

• (b)(1)(xiii): provide protection from malicious code at appropriate locations within organisational information systems;
• (b)(1)(xiv): update malicious code protection mechanisms when new releases are available;
• (b)(1)(xv): perform periodic scans of the information system and real-time scans of files from external sources as files are downloaded, opened or executed.

Any business product in this database with a central console can help address those three on the devices where it is installed. The Level 1 work is making sure it is installed on every device in scope and keeping the console export for the annual self-assessment.

What does CMMC Level 2 require the endpoint to prove?

Level 2 is built on the 110 requirements of NIST SP 800-171, which add audit logging, system monitoring and incident handling. The endpoint product becomes a Security Protection Asset, which under 32 CFR 170.19(c)(1) is assessed against the Level 2 requirements relevant to the capabilities it provides. In plain terms, the assessor will look at whether your EDR does what your System Security Plan says it does.

DFARS 252.204-7012, which already sits in contracts involving covered defense information, adds three incident duties (clause text):

Antivirus alone keeps almost nothing of use for 7012(e). That, more than any CMMC practice number, is the practical reason a CUI supplier should consider EDR.

Which products are positioned for CMMC?

These are the products whose vendors publish CMMC relevance, with their other compliance positions:

Product	HIPAA BAA	Supports PCI DSS	CMMC-relevant	FedRAMP
CrowdStrike Falcon Go	Unknown	Yes	Yes	authorized
Sophos Endpoint	Unknown	Yes	Yes	none
SentinelOne Singularity Control	Yes	Yes	Yes	authorized
Huntress Managed EDR	No	Unknown	Yes	none
SentinelOne Singularity Complete	Yes	Yes	Yes	authorized
Cynet All-in-One	Unknown	Yes	Yes	none

And what each of them includes. The SIEM column matters because Level 2 audit-logging requirements are easier to evidence when endpoint events land in a central log:

Product	EDR	24/7 managed response	SIEM integration
CrowdStrike Falcon Go	Not offered	Not offered	Not offered
Sophos Endpoint	Not offered	Not offered	Included
SentinelOne Singularity Control	Included	Not offered	Included
Huntress Managed EDR	Included	Included	Included
SentinelOne Singularity Complete	Included	Not offered	Included
Cynet All-in-One	Included	Included	Included

The FedRAMP column answers a narrower question than it seems to. 7012(b)(2)(ii)(D) requires a cloud service that stores, processes or transmits covered defense information to meet security requirements equivalent to the FedRAMP Moderate baseline. Whether the endpoint vendor's console is such a service depends on what telemetry it holds and how your assessor scopes it. Vendors disagree: Huntress, for example, argues that it operates as a Security Protection Asset and does not need FedRAMP authorisation. Settle the point with your assessor before you buy, not during the assessment.

What does CMMC-ready endpoint security cost?

Product	Per unit per month	10 seats / yr	25 seats / yr	100 seats / yr
CrowdStrike Falcon Go	$5.00 /endpoint/mo	$599.90	$1,499.75	$5,999.00
SentinelOne Singularity Control	$6.67 /endpoint/mo	$799.90	$1,999.75	$7,999.00
SentinelOne Singularity Complete	$15.00 /endpoint/mo	$1,799.90	$4,499.75	$17,999.00
Huntress Managed EDR	Min 50 seats	Min 50 seats	Min 50 seats	$9,588.00

The endpoint licence is usually a small part of a Level 2 budget next to assessment and remediation work, so do not choose on licence price alone. For a product this table leaves out, the SMB endpoint security price index lists every published price from 5 to 100 seats.

What should each supplier buy?

Machine shop or small supplier with FCI only (Level 1). A centrally managed product on every device that touches contract information, set to update automatically, with a monthly export saved for the self-assessment. CrowdStrike Falcon Go ($59.99 per endpoint per year) is on the CMMC-relevant list with a published price, though it has no EDR, which Level 1's three malicious-code practices do not ask for.

Subcontractor of 10 to 50 people handling CUI (Level 2). EDR with a 24/7 team or an in-house process that meets the 72-hour report, plus a documented way to keep telemetry for 90 days after a report. SentinelOne Singularity Complete ($179.99 per endpoint per year) carries a FedRAMP authorisation, but its 24/7 managed response is not offered, so the 72-hour clock rests on your own staff or an MSP. Huntress Managed EDR ($107.88 per endpoint per year) includes the team; bought direct it starts at 50 endpoints, so a smaller subcontractor gets it through an MSP, where Huntress sets no minimum.

Supplier whose MSP runs its IT. If the MSP's services process CUI, 170.19 puts those services inside your assessment scope as an External Service Provider. Ask the MSP for its own evidence pack before Phase 2 solicitations reach you.

Supplier building a CUI enclave. Put only enclave devices on the Level 2 product. Fewer devices in scope means a smaller licence bill and a shorter assessment.

What endpoint security mistakes do defense suppliers make?

• Believing a product is "CMMC certified". Organisations are assessed; products are not.
• Buying antivirus for CUI systems. It keeps little of the monitoring data 7012(e) asks you to preserve for 90 days.
• Leaving the MSP's console out of the System Security Plan. An External Service Provider's services are assessed as part of yours.
• Waiting for Phase 2 to start. A C3PAO assessment needs evidence gathered over time, and 10 November 2026 is weeks away.

Methodology and caveats

On 9 October 2026 we checked FAR 52.204-21, 32 CFR 170.3 and 170.19 and DFARS 252.204-7012 in the official eCFR text; the 10 November 2025 effective date of the DFARS CMMC rule (published 10 September 2025) was confirmed through the Federal Register's API. Tables are filtered to products whose vendors publish CMMC relevance. "CMMC-relevant" is the vendor's own positioning, recorded with its source and date.

A CMMC Registered Practitioner or C3PAO, not a buyer's guide, decides what your assessment will accept.
