Most companies prepare for CMMC backwards.
Here's the right way.
SentinelSSP helps defense contractors start with scope, work through controls, map evidence, track gaps, and generate readiness outputs in one connected workflow.
No credit card required. Upgrade when you're ready for the full Level 2 workflow.
110 CMMC Controls
Full Level 1 and Level 2 coverage
Accurate SPRS Score
Control-by-control, DoD Assessment Methodology
The Problem
CMMC compliance is overwhelming. It doesn't have to be.
The consultant quote
You call a CMMC consultant or RPO and get a quote for $25,000 to $50,000. That price covers their time, not your compliance.
The blank SSP
Every template online is a generic starting point that assumes you already know what you're doing. You're still on your own.
The deadline pressure
Your contract requires CMMC certification and the timeline is real. Every week without a plan is a week closer to losing the work.
The Solution
A guided workspace that takes you from
overwhelmed to organized.
SentinelSSP replaces the blank page with a structured, step-by-step process built around exactly how CMMC assessments work.

How It Works
From blank page to a complete CMMC
documentation package - step by step.
1
Define Your Scope
Map your CUI environment and identify exactly which systems, people, and locations are in scope. Skip everything that isn't.
2
Get Your SPRS Score
Work through the controls with guided, plain-language explanations to get an accurate SPRS score calculated with the DoD methodology. Know exactly where you stand.
3
Build Your Documentation
Generate your System Security Plan and your full CMMC policy document set, pre-populated with your actual environment details.
4
Track Your Gaps
See exactly which controls you still need to address, prioritized by severity, so you know what to fix before your assessment.
Not a document dump.
One connected CMMC workflow - scoping, scoring, policies, evidence, and your SSP all feed into each other. Change something upstream and the downstream is already there.
Features
Everything you need. Nothing you don't.
Scoping Advisor
Know exactly what's in scope before you start.
Most contractors waste months working on the wrong systems. Our Scoping Advisor walks you through your environment step by step so you only document what actually matters to CMMC assessors.
Scoping Advisor
Which systems process, store, or transmit CUI?
SPRS Assessment
An accurate SPRS score, control by control.
Assess each of the 110 Level 2 controls with guided, plain-language explanations - no NIST expertise required - and get an SPRS score calculated with the DoD Assessment Methodology. Assessor-grade accuracy, not a quick guess or an AI estimate.
SPRS Score
Control Tracker
Work through all 110 controls with clear guidance.
Every CMMC Level 1 and Level 2 control explained in plain English, with implementation guidance written for IT professionals and business owners across the DIB. Mark controls as implemented, in progress, or not applicable with a full audit trail.
Access Control
22 controlsEvidence Mapping
Know exactly what evidence each control needs.
For every control, see the evidence an assessor actually examines - grounded in the CMMC Assessment Guide and NIST 800-171A - then track what you have against each requirement. Map your existing artifacts to the controls they satisfy and go into your assessment knowing exactly where your coverage stands.
Recommended evidence
From the CMMC Assessment Guide
Evidence Traceability and Gap Analysis
Generate a complete evidence traceability package.
Map every control to its evidence and generate a professional traceability matrix - in PDF or Excel. See exactly which controls are covered and which still need evidence, so you walk into assessment prep organized, with a clear view of coverage and gaps.
Your evidence stays yours - we document where it lives without storing your files, so you keep your artifacts in your own environment.

Ask anything. Get a straight answer.
Sentinel is trained on CMMC assessment guides, NIST 800-171, and DoD methodology. Ask any compliance question and get an answer grounded in the actual standards, not generic advice.
Does AC.L2-3.1.1 apply if we only work on government contracts part of the year?
Yes. AC.L2-3.1.1 applies whenever your systems could process, store, or transmit CUI, regardless of the time of year. Per 32 CFR Part 170, CMMC requirements attach to the contract. If you handle CUI at any point, the controls must be implemented and maintained continuously.
What counts as authorized access in practice?
Security-first. Built for the defense industrial base.
Encrypted and isolated
All data is encrypted in transit with TLS and at rest. Every organization's data is isolated at the database level with row-level security, so your workspace stays separate from every other account's.
Built by practitioners
We built the tool we wished existed when CMMC first landed on our desk. Every feature exists because a real defense contractor needed it.
Standards-grounded
Every control, question, and piece of guidance is grounded in CMMC 2.0, NIST SP 800-171, and the DoD assessment methodology. No paraphrasing, no generic advice.
Simple, transparent pricing.
No hidden fees. No surprise charges. No enterprise contracts.
