CMMC Level 1 & Level 2 · NIST SP 800-171

CMMC compliance, without a consultant on retainer.

Sentry171 walks small defense contractors through every step: work out what applies to you, assess it objective by objective, get your SPRS score, and produce the policies, System Security Plan and records an assessor or prime will ask for.

No credit card. Your data is yours. Export everything any time.

CMMC is now in DoD contracts. Most small shops aren't staffed for it.

If you handle contract information for the Department of Defense, you need a current self-assessment, a score on file, and the documents to back it up.

110 requirements, 320 objectives

NIST SP 800-171 is long, and written for people who already speak it. Knowing where to start is half the battle.

Paperwork that has to agree

Your score, your SSP, your policies and your POA&M all have to tell the same story. Spreadsheets drift apart.

It never ends

Log reviews, training, access reviews, the annual affirmation. Compliance is a calendar, not a project.

How it works

Plain-language questions first. The paperwork follows from your answers, so nothing contradicts anything else.

Scope

Answer short questions about how your company works: where CUI lives, how accounts are managed, what you use. Your answers decide which requirements apply.

Assess

Mark each objective met, not met or not applicable, with suggested wording to start from. Your SPRS score updates as you go.

Prove it

Generate policies and your System Security Plan, plan fixes for the gaps, and keep signed, dated records of every affirmation.

What you get

Everything a small contractor needs for a self-assessment, in one place, with no consultant hours.

Guided scoping

Questions that settle what applies to your environment, so the assessment only asks about what's relevant.

Objective-level self-assessment

All 320 assessment objectives, with N/A justifications and suggested narratives.

SPRS score, with proof

Your score as of any date, rebuilt from history, and a proof package for an assessor or prime.

Policies from your answers

14 policy families, generated from your scoping and assessment, approved and versioned.

System Security Plan

An SSP built from everything above. Issue versions with a named approver.

POA&M as action plans

Turn gaps into corrective action plans with ready-made steps, owners and due dates.

Compliance calendar

22 recurring obligations, from log reviews to training, with evidence attached when done.

Records in one place

Assets, privileged accounts, personnel, training, incidents, maintenance, media disposal and changes.

Your team, your assessor

Invite colleagues as members, and give a consultant or assessor read-only access.

Built by a defense contractor, for defense contractors

Sentry171 was built inside a small defense contractor working through CMMC itself, because the tools we found were made for companies with a compliance department. It does what we needed: tells you what applies, walks you through it, and keeps the record straight.

Your data stays yoursEach company's records are isolated from every other's. Owners can export everything, or close the account, at any time.
Nothing is inventedMissing answers show as missing. A document can't be approved until it's complete.
A record that holds upApproved policies, issued SSPs and affirmations are kept as fingerprinted versions that can't be quietly edited.
