The ZeroGap Methodology

How every engagement works.

The ZeroGap Methodology Compliance Execution Framework follows four phases — the same process whether you're doing a CMMC Level 1 self-assessment or preparing for a FedRAMP authorization. Scaled to your organization.

1

Discover

Map Your World
We capture your entire environment — tech stack, CUI boundaries, identity platform, endpoints, cloud, VDI, home office access — in plain language before a single practice is assessed.
2

Analyze

Gap Assessment
Every interview question and finding is built from your intake data. We reference your actual tools by name. Your SPRS score updates live with every practice decision.
3

Execute

Close the Gaps
Every NOT MET finding comes with prioritized remediation steps written for your specific tools. Auto-built POA&M with 90/180/270-day target lanes.
4

Deliver

Action Plan Handoff
Complete assessment package with scoring, domain heatmap, evidence checklists organized by assessment method, and a stakeholder briefing your leadership can act on.

FAQ

Frequently asked questions.

Quick answers to the questions we hear most from defense contractors and federal organizations.

What is CMMC and who needs it?
The Cybersecurity Maturity Model Certification (CMMC) is a DoD framework that requires defense contractors to demonstrate cybersecurity practices before being awarded contracts. Any organization in the Defense Industrial Base (DIB) that handles Federal Contract Information (FCI) or Controlled Unclassified Information (CUI) needs CMMC certification. Level 1 covers basic FCI safeguarding (17 practices), while Level 2 aligns with NIST SP 800-171 (110 practices) for CUI protection.
What's the difference between CMMC Level 1 and Level 2?
Level 1 requires a self-assessment against 17 basic safeguarding practices and an annual SPRS score submission. Level 2 maps to all 110 practices in NIST SP 800-171 and — for most contracts — requires a third-party assessment by a C3PAO (Certified Third-Party Assessment Organization). Level 2 is required when your contract involves CUI.
How long does CMMC certification take?
Timeline depends on your starting point. Organizations with mature security programs can be assessment-ready in 3–6 months. Those starting from scratch typically need 6–12 months for gap remediation before scheduling a C3PAO assessment. The ZeroGap Methodology accelerates this by providing environment-specific remediation steps rather than generic checklists.
What is a vCISO and why would I need one?
A virtual Chief Information Security Officer (vCISO) provides executive-level cybersecurity leadership on a fractional basis. Instead of hiring a full-time CISO, you get strategic security guidance, governance oversight, board-level reporting, and compliance leadership at a fraction of the cost — especially valuable for small and mid-size defense contractors.
What frameworks does Threat Zero Cyber support?
We support CMMC, NIST SP 800-171, NIST SP 800-53, FedRAMP 20x, NIST RMF, NIST CSF, PCI DSS, HIPAA, FISMA, DFARS, NIST SP 800-37, and ISO 27001. Our ZeroGap Methodology scales across all these frameworks — the same rigorous process whether you're doing a CMMC Level 1 self-assessment or preparing for FedRAMP authorization.
How is Threat Zero Cyber different from other compliance firms?
Most firms hand you a gap assessment spreadsheet and walk away. We close the gaps. Our AI-powered ZeroGap Methodology generates environment-specific findings, references your actual technology stack, and provides prioritized remediation steps. Every engagement gets better through our continuous quality feedback loop.
