Your Partner for the Security a Defense Contract Requires.
Pass Your Assessment.
CMMC Level 2 and NIST 800-171, scoped tight and assessment-ready on a schedule you can plan around. Aegis installs and documents the controls; our team scopes the boundary, prepares the evidence, and sits with you while the C3PAO assesses.
CMMC and NIST 800-171 →Stay Secure.
Alerting tuned to your environment, high-priority alerts reviewed by Atomus, and when one triggers we declare an incident and run the response — DFARS 7012 reporting included. Managed Security on the same platform — no second vendor, no second console.
Managed Security →Run on Government Cloud.
GCC High tenants, migration, licensing, virtual desktops, mobile. We stand it up, harden it, and manage it; you keep working.
Microsoft Government Cloud →Atomus Aegis: Implemented by Software, Managed by People.
Deployed across your whole organization, or as an enclave for the users who handle CUI — your scoping call decides.

We confirm your company details, the systems that will hold CUI, and the shape of the deployment: whole organization or enclave.
Government Cloud
Microsoft validates your organization; we stand up or connect your GCC / GCC High tenant, order the licenses, and configure the tenant to a hardened baseline.
Users and Devices
You choose which users come onto Atomus; we agree the first rollout group, then deploy Aegis to their computers or provision virtual desktops, and enroll mobile devices.
Compliance Build
With our team, you complete the asset and system inventories and required registries, and your policies, procedures, and plans are drafted to your scope and reviewed by Atomus for you to customize and sign in the Compliance Portal.
Assessment Readiness
We work the Level 1 and Level 2 checklists with you, prepare the evidence, and coordinate with your C3PAO. After you pass, Managed Security and Managed Compliance keep running.
Choose How Your Team Runs Atomus.
A Hardened Desktop in Government Cloud.
CUI stays in the tenant, not on the machine. Right for shared workstations, contractors, and users on personal or customer-owned hardware.
Aegis on the Computers People Already Use.
Controls, monitoring, and encryption applied in place — no new hardware, no change to the CAD, CAM, and engineering software your team runs locally.
Enrolled Phones for Mail and Messages.
Government-cloud mail, Teams, and files on managed iOS and Android, so people on the floor or on the road stay inside the boundary.
Most companies use a mix. VDI alone is the wrong answer for most engineering-heavy contractors, and we’ll tell you which is which.

We were looking for someone who could tell us what we needed, who understood what the problems were and what level of compliance we needed. We knew we needed a partner specialized in Aerospace and Defense cybersecurity.
It's cybersecurity and compliance in a can for small businesses. Simply put, it works.
Atomus radically simplified the cybersecurity and compliance process for my company. We now have an industry leading cybersecurity and compliance program, and the SPRS score to show it.
Why Defense Companies Choose Atomus
We Only Do Defense.
Spun out of a DoD Cybersecurity Initiative, and every customer since has been a US defense or aerospace company. The platform, the documentation, and the team were built for NIST 800-171, DFARS 7012, and CMMC — not adapted from a commercial product. We hold CMMC Level 2 ourselves, 110/110.
You’re Never Alone with the Assessor.
We lock the scope in writing, prepare the evidence package, coordinate with your C3PAO, and sit with you through assessment week. Then we run the quarterly reviews so you stay ready for the next one.
We Partner with Your IT Provider.
Keep the IT provider you already trust. Atomus runs security and compliance — and now AI you can use with CUI — managed together, alongside them. Partners, not competitors.
Already Have an IT Provider? Keep Them.
They run IT; Atomus runs security and compliance.
Questions We Get on the First Call
How much of my environment is in scope?+
Only the users and systems that handle CUI. We scope the boundary with you on the scoping call and lock it in writing before anything is deployed.
Do we have to build a separate enclave?+
No — most customers run Atomus across the whole organization. An enclave for the users who handle CUI is an option when it makes scoping sense.
Do I have to replace my computers or move to virtual desktops?+
No — endpoint, virtual desktop, or mobile, chosen per user. Most companies use a mix.
Can I keep my current IT provider?+
Yes. They keep running IT; Atomus runs security and compliance alongside them.
How long until we’re ready for assessment?+
You get a timeline to assessment as part of our free consultation, before you sign anything with Atomus. It depends on scope: most of the time goes to migration and evidence collection, and Aegis handles the control implementation in the background.
Who performs the assessment?+
An independent C3PAO. Atomus coordinates with them and supports you through the assessment.
What happens after we pass?+
Managed Security and Managed Compliance keep running: alert review and incident response, quarterly reviews, and documentation reviewed by Atomus and kept current.
