Atom Cybersecurity is a US-based managed security and compliance practice that works exclusively with the Defense Industrial Base. We help DoD contractors and their subcontractors reach CMMC 2.0 and ITAR compliance — and, just as importantly, sustain it between assessments, affirmations, and the next contract.
We didn't back into defense work. These are the positions we started from — and the reasons contractors keep us around after the assessment is passed.
An SSP that describes controls nobody actually runs is a liability, not a defense. We treat every control as something that has to be operated, monitored, and evidenced on a normal Tuesday — not reconstructed the week before an assessment.
A flattering SPRS score helps no one when a C3PAO shows up. Our readiness work starts with an honest score against all 110 NIST SP 800-171 controls, and we'd rather deliver an uncomfortable number early than an audit finding later.
CUI and ITAR-controlled technical data carry personnel and location obligations that ordinary IT ignores. Our operations are US-based and staffed by US persons, and we architect enclaves so that controlled data never lands where it shouldn't.
Passing an assessment and stopping a real intrusion are not the same test. We build programs that satisfy the assessor's evidence requirements and hold up when someone is actually trying to get into your CUI environment.
Most contractors don't need another tool — they need a defensible boundary, a plan the assessor will accept, and someone operating the controls after the kickoff excitement fades. Our operating model is built around that reality.
We want this to be unambiguous, because the distinction matters legally and practically. Atom Cybersecurity is a managed security service provider and a compliance enabler. We prepare you for certification and keep you compliant after it. We are not an accredited assessor.
The official CMMC Level 2 certification assessment must be performed by an independent, accredited Third-Party Assessment Organization (C3PAO). We do not issue CMMC certifications and we do not sit on both sides of that line — separating the party that builds the program from the party that judges it is the point.
CMMC 2.0 • 32 CFR Part 170 • DFARS 252.204-7021
The contractors we serve are held to a high evidentiary bar — so are we. This is where our team, certifications, and federal registrations are documented.
This practice exists for organizations that handle FCI, CUI, or ITAR-controlled technical data. If your security needs are commercial — managed detection and response, email defense, backup, and vCISO leadership without the CMMC and export-control overhead — that's our sister practice.
Same team, same standards, without the defense-specific compliance scope. Managed security operations for growing businesses that simply want to be well-defended.
Request a readiness assessment. We'll scope your CUI environment, score you against NIST SP 800-171, and hand you a prioritized, defensible path to the level your contracts require.
