Nothing asserted that evidence cannot support.

Six practices, one discipline: we help defense contractors, cloud providers, and boards make cybersecurity assertions — to assessors, primes, agencies, SPRS, and investors — that hold up under examination.

The practices

Six fronts. Every one ends in evidence.

Every practice exists because a different counterparty examines your security — an assessor, an agency, a prime, a board, an adversary. Start on the front where you're being examined next.

01CMMC & DIB Assurance CMMC · NIST 800-171 · CUI · SPRS Protect federal contract eligibility by making every assertion — SPRS score, SSP, executive affirmation — supportable under assessment. → 02FedRAMP & Federal Cloud FedRAMP 20x · KSI · Evidence · ConMon Turn a commercially successful product into a federally usable service — with a boundary, evidence engine, and ConMon that keep pace with releases. → 03RMF & Zero Trust RMF · 800-53 · Identity · Segmentation Security architecture that carries authorization, modernization, and mission — not a compliance layer bolted on after the design is done. → 04Executive Cyber & vCISO Boards · Governance · Investment · Council Senior, founder-level judgment for the decisions leaders must sign and defend — materiality, spend, governance, and affirmations. → 05Resilience & Supply Chain Incident Command · Ransomware · Suppliers Rehearsed incident command, tested recovery, and supplier assurance — so one bad weekend never becomes a mission or contract failure. → 06Emerging Tech & AI Secure R&D · AI Governance · Post-Quantum Security designed in while the product is still on the whiteboard — before requirements, diligence, or production make change expensive. →

The discipline

Work backwards from the moment of examination.

Compliance documents are easy to write and hard to defend. Whatever the framework, every engagement runs the same arc:

01 Determine what actually applies

CMMC level, FedRAMP pathway, RMF baseline — and just as important, what doesn't apply yet. No overbuilding, no premature spend.

02 Draw a defensible boundary

Where FCI, CUI, and federal data actually live — enclave, federal edition, or enterprise-wide — decided before a single control is bought.

03 Build operating evidence

Controls implemented so they generate their own proof — logs, artifacts, and dashboards an assessor, prime, or board can pull on.

04 Keep it defensible

Continuous assurance as the product, suppliers, and requirements change — so the assertion still holds in year two, not just on assessment day.

Why NSC

A boutique firm, built for the moment of examination.

National Security Corporation is a boutique cybersecurity firm for federal compliance — CMMC, FedRAMP, and RMF. Founded in 1988 and founder-led ever since: no bench of juniors, no templated binders.

Same frameworks

CMMC, FedRAMP, RMF, NIST SP 800-171 and 800-53 — the same control families and assessors run through every practice.

Same discipline

Evidence first. Nothing is asserted — to an assessor, a prime, a board, or SPRS — that operating evidence cannot support.

Same seniority

The practitioner who briefs Fortune 1000 boardrooms is the same one who scopes your boundary and stands behind your evidence.

The record

Serving government, military, and commercial clients since 1988.

Sound familiar?

The moment this becomes urgent.

"A solicitation just dropped with CMMC Level 2 in it — and our SPRS score is a guess." Practice 01 · CMMC & DIB → "An agency loves the product. Then they asked if we're FedRAMP authorized." Practice 02 · FedRAMP → "Our zero-trust roadmap is three diagrams and a mandate — no executable plan." Practice 03 · RMF & Zero Trust → "I'm the one signing the affirmation — and I can't tell if the evidence is real." Practice 04 · Executive Cyber → "We have an incident-response plan. We've never once rehearsed it." Practice 05 · Resilience → "Diligence flagged our security debt — two weeks before the term sheet." Practice 06 · Emerging Tech & AI →

Start with the assertion you have to defend.

An SPRS score, an authorization, a board representation, an affirmation — tell us what you have to stand behind, and we will tell you what it takes to support it.
