Secure the Environment.
Qualify for the Work.
Sustain Compliance.
Common Cyber helps defense contractors and federal programs design and build secure environments, prove they meet the requirements, and sustain them for national security work.
Built for defense and federal environments
We work where cybersecurity, compliance, engineering, and mission execution intersect — with organizations that handle controlled information or need a clear posture to pursue defense work.
Three markets. One operating standard.
Defense Contractors
CMMC and NIST SP 800-171 readiness for organizations handling FCI or CUI.

RMF, ATO support, security engineering, and Cross Domain Solution execution.

Every engagement is organized around decisions and operating outcomes, not activity for its own sake.
Qualify for defense work
Protect FCI and CUI
Establish a defensible scope
Reduce authorization delays
Close technical and documentation gaps
Sustain compliance after implementation
Start with an assessment
A full assessment and gap analysis of your environment against the program requirements, and a written statement of work for the remediation that follows.
CMMC Readiness and Scope Assessment
A defined first step that establishes scope, readiness, and a practical remediation path.
Federal Authorization Readiness Review
Where does authorization stand, and what is blocking the path forward? The review identifies missing evidence, engineering dependencies, and the critical path.
How we work
Each phase produces the inputs the next one needs.
1. The first step
Assess
Find the boundary, the gaps, and the risk.
2. The project
Remediate
Turn findings into owned, prioritized work.
Engineer & Implement
Build controls, documentation, and evidence that holds up.
Prepare & Authorize
Get the evidence and the package ready for the assessor or the authorizing official.
3. Ongoing
Sustain
Keep controls and evidence operating as the environment changes.
Why Common Cyber
What we bring that a generalist does not.
- Defense and federal specialization, not a bolt-on compliance offering
- Technical implementation — we build controls, not just documents
- Leadership experience in RMF, ATO, and security engineering
- Leadership experience in aviation and operational environments
- Disciplined scope, delivery, and acceptance criteria
- SBA-certified Service-Disabled Veteran-Owned Small Business
- Support that continues after the initial project
- Cross Domain Solution support and authorization readiness
Compliance is an operating function
Compliance decays quietly. Someone changes a system, the person who owned a control leaves, the evidence goes stale, and nobody notices until an assessor asks.
Managed compliance keeps controls, evidence, and assigned ownership operating after the project ends.
Explore managed complianceWhat managed compliance covers
- Continuous monitoring
- Evidence maintenance and documentation updates
- Recurring risk reviews
- Authorization and compliance sustainment
- Advisory support
Partner ecosystem
We work with partners that need defense-focused technical, compliance, and engineering work without stepping on their customer relationships.

What a CMMC Readiness Assessment Actually Produces
You are spending $30,000. Here is what you get, what each piece is for, and how it connects to the decisions that come next.
Read moreWhat a Prime Contractor Is Actually Asking For, and What It Means
A prime sends a questionnaire, a flow-down clause, or a request for your SPRS score. They are testing whether you know your information, your obligations, your boundary, and your evidence.
Read moreWhat Your SPRS Score Tells a Prime Contractor
Your SPRS score tells a prime how seriously to take your cybersecurity program. The number matters less than whether the evidence behind it holds up.

Define the boundary before you build.
The fixed-fee assessment clarifies what is in scope and turns the findings into a practical statement of work.
