Managed IT · Cybersecurity · Compliance · Specializing in CMMC

We run your IT, secure it, and keep you compliant.

One team for managed IT, cybersecurity, and compliance, built for regulated industries and the defense supply chain. We specialize in CMMC and NIST 800-171, and we run the controls day to day, not just write them down. The same people who secure your environment carry your compliance on it.

Cyber AB Registered Practitioner (RP). Advisory and implementation under the Cyber AB Code of Professional Conduct.
One provider

Your IT, your security, and your compliance. One team, one environment.

Most contractors run this across an MSP, a security vendor, a compliance consultant, and a cloud provider, then spend their time refereeing the gaps between them. We are all of it, which is the only way the controls you document stay the controls that are actually running.

Managed IT

We run it

Microsoft 365 and Entra administration, endpoints, networks, identity, and helpdesk, including the GCC High or enclave environment your CUI lives in. Tickets answered, patches landing, backups verified, the day-to-day handled and off your desk.

Managed security

We secure it

Hardening, monitoring, patching, vulnerability management, and incident response. Your controls get operated and watched, not written down once and forgotten.

Compliance

We keep you compliant

CMMC and 800-171 scoping, implementation, SSP and POA&M, SPRS, and assessment readiness, built on the same environment we run, so the evidence is real and current.

One team, one environment, one number to call. The people who write your compliance are the same people who pick up when something breaks on a Friday afternoon.

Recognize these?

If these clauses are on your contract, the clock has already started.

These are the DFARS clauses that put CUI obligations on you. They are usually the reason a prime or a contracting officer is suddenly asking questions. We work all of them.

252.204-7012
Safeguarding CUI & incident reporting

Secure covered defense information to NIST 800-171, report a cyber incident to DoD within 72 hours, keep CUI in a FedRAMP-Moderate cloud, and flow the same down to your subs. In contracts since 2017.

252.204-7021
CMMC status

Hold and maintain a CMMC status at the level your contract names, affirm continuous compliance in SPRS every year through an affirming official, and flow the requirement down. This is the clause Phase 2 turns on, paired with the 252.204-7025 solicitation provision.

7019 / 7020 changed
If your contract still cites the old numbers

As of February 1, 2026, DoD’s class deviations under the Revolutionary FAR Overhaul direct the new numbering: the self-assessment provision at 252.204-7019 is retired, 7020’s assessment requirement is used as 252.240-7997 under the new DFARS Part 240, and FCI’s 52.204-21 becomes 52.240-93. Your existing contracts and the codified DFARS may still show the old numbers, so both have to be recognized. We track both.

An 80% score, 88 of 110, with only the lower-weighted gaps parked on a POA&M, earns conditional status, enough to win the award. But every one of those gaps has to be closed within 180 days or the status expires.

The difference

A binder isn’t compliance. Running the controls is.

Plenty of shops will sell you a binder: a generic SSP, a confident SPRS score, an invoice. Then they disappear. None of it is wired to what’s actually running, and none of them are there when something breaks.

That gap is the whole problem. An assessor checks the claim against the system. When the document says one thing and your tenant says another, that’s a finding. And since the 48 CFR rule took effect, an affirmation you can’t back up carries real exposure, not just a failed assessment.

We work the full cycle. We build the document out of your environment, implement and harden the controls ourselves, and stay on to operate and defend them. The score is the score, and the system keeps passing.

“If we can’t show it, it doesn’t go in the document.”

No inflated SPRS numbers. No invented credentials. No control marked met without an artifact behind it. As a Cyber AB Registered Practitioner, that conduct standard isn’t optional. It’s also the only version that survives an assessment.

Who we serve

Built for regulated businesses. Deepest in the defense supply chain.

If you carry a compliance obligation, whether it flows from a DoD contract, a health regulator, or a financial one, we run the IT and the security underneath it. The defense supply chain is where we go deepest, but the model is the same: one team that operates the environment and proves it.

Manufacturers & DIB subs

Defense and aerospace suppliers handling CUI and ITAR-controlled technical data. CMMC Level 2 and export control are the same job here, run as one program with the CUI enclave to match.

Service & consulting firms

Professional, engineering, and IT services that receive CUI as a subcontractor to a prime or an agency. Same Level 2 obligation, often arriving through a flow-down you did not expect.

GSA & civilian suppliers

Schedule holders and civilian-agency contractors carrying Section 889, FCI, and TAA today, and the CUI requirements heading their way under the proposed FAR rule.

Healthcare, finance & other regulated SMBs

Practices and firms answering to HIPAA, the FTC Safeguards Rule, or NYDFS. Same managed model, a different rulebook, run by people who already work inside regulated environments every day.

What we do

From flow-down to certified, and everything after.

One practice runs the whole lifecycle: scope, implement, document, prepare, and operate. We prepare you for the assessment; an accredited C3PAO performs it. After that, we keep it running.

01

Scope the CUI boundary

Find where CUI actually lives and draw the assessment boundary so you are securing what is in scope, not paying to harden everything by default.

02

Gap assessment

Measure current state against the 320 assessment objectives in 800-171A. An honest SPRS picture and a prioritized list of what is missing.

03

Implement and harden

We put the controls in place across Microsoft 365, Entra, and endpoints: conditional access, MFA, logging, encryption. We harden the environment, not just describe it.

04

SSP and POA&M

Documentation built from your environment and mapped to evidence, structured the way an assessor reads it. Open items tracked with real close dates.

05

Assessment readiness

Walkthroughs, a dry run against the objectives, and the artifact index the C3PAO will ask for. You go into the assessment knowing every answer.

06

Operate, maintain, and respond

Compliance drifts the day after the assessment. We run the controls, keep evidence current, and respond when something gets through. Managed upkeep and incident response under one roof.

How we work

One accountable practitioner, not a ticket queue.

Compliance work is judgment work. You should know who is making the calls on your environment, and the person who scopes the job should be the one who does it.

The practitioner model
Senior-led, and accountable.

Every engagement is run by a Cyber AB Registered Practitioner, hands-on across Microsoft 365, Entra, and Defender. The person who scopes your CUI boundary is the one who writes your SSP and stands up the controls behind it. Nothing is handed to a junior you never meet. And because we prepare you for assessment without ever assessing you, there is no conflict of interest in the room.

01You own everything.

Every policy, SSP, POA&M, and admin credential is yours and stays in your tenant. Nothing is locked behind our tooling. If we ever part ways, your compliance does not leave with us.

02Fixed scope to start.

We begin with a defined scoping engagement, not an open-ended retainer. You see exactly what the work involves, and what it costs, before you commit to it.

03Straight answers.

If a control is failing, if your SPRS score is overstated, or if you do not actually need what someone sold you, you will hear it from us plainly.

04Inside your scope, not around it.

As the team that also runs your IT, we are built into your environment as your External Service Provider. We document that relationship in your SSP with a customer responsibility matrix, and we scope our own footprint deliberately so it strengthens your assessment instead of complicating it.

Evidence, not assertions

Every control we claim, we can show.

Anyone can write that a requirement is met. We build the proof underneath it, so each control traces from the standard to a real artifact in your tenant. Here is the control most programs get wrong, start to finish.

The requirement 800-171 · 3.1.3

Control the flow of CUI in accordance with approved authorizations. Five objectives in 800-171A, from defining the flow-control policy to enforcing approved sources and destinations. It is the scoping control, and the one weak programs fail most often.

What we implement The control

We map where CUI actually enters, moves through, and leaves your environment, then enforce those paths: boundary and proxy rules, Conditional Access, DLP, and a scoped CUI boundary. Every authorization is written down, then enforced, never assumed.

The artifact we leave The proof

A CUI data-flow diagram tied to the authorizations, boundary and DLP rule exports, and the scoped boundary definition. Mapped objective by objective, [a] through [e], in your SSP for the assessor to open.

The assessor sees the artifact, not just the claim. We do this across all 110 requirements and their 320 objectives.

Scope of practice

Specialist in CMMC. Fluent in what surrounds it.

Our depth is CMMC and the standard underneath it: NIST SP 800-171 Revision 2, the revision DoD assessments and SPRS scoring run against today. We build to Rev 3 where a contract or a forward-looking client calls for it, and we treat the export-control rules that ride alongside CUI as part of the same job, not a separate vendor.

Where we specialize
CMMC Level 1 (FCI) CMMC Level 2 (CUI) NIST SP 800-171 (Rev 2 & Rev 3) ITAR / EAR export control CUI enclaves (GCC High / GovCloud) SPRS scoring & affirmation
Also supported, for contractors who answer to more than one regulator
HIPAA Security Rule FTC Safeguards Rule NIST SP 800-53 NIST CSF 2.0 ISO 27001 SOC 2 CIS Controls

On state law we anchor on the regimes that carry real weight rather than reciting all fifty. The one to know is New York’s NYDFS 23 NYCRR 500, the cyber rule the federal Safeguards Rule was modeled on, alongside California’s CCPA/CPRA for privacy. From there we map breach-notification duties and the widening state privacy patchwork to the states you actually operate in.

Where the rule stands

Readiness is now a scheduling problem too.

CMMC is no longer a policy you can watch from a distance. It’s in contracts, and the people who run the assessments are in short supply.

NOV 10, 2025

It became contractual

The 48 CFR final rule took effect. CMMC requirements now appear in DoD solicitations and awards through DFARS 252.204-7021, and at award there is no grace period.

NOV 10, 2026

Third-party assessments arrive

Phase 1 leans on Level 2 self-assessment. Phase 2 begins on this date, when a C3PAO-led certification becomes a condition of award for most CUI contracts, on a ramp that runs to full implementation in 2028.

THE BOTTLENECK

~100 assessors, tens of thousands waiting

Around 100 authorized C3PAOs and roughly 760 certified assessors exist for the tens of thousands of contractors that will need a Level 2 certification. Wait times are already projected past 18 months. Ready early gets you on the calendar; the rest queue.

Sources: 48 CFR final rule, Federal Register, Sept 10 2025 (eff. Nov 10 2025); 32 CFR Part 170; Cyber AB town-hall figures, Q1 2026.

Starting early is not caution. It is how you get on a C3PAO’s calendar before the queue forms.

And it will not stop at Defense. The proposed FAR CUI rule would extend the same 800-171 baseline to every federal contractor handling CUI, civilian agencies included. It is not final yet, but the clients who build the program once, for CMMC, are the ones already standing when that wave lands.

Start here

Find out where you actually stand.

The first call is a scoping conversation, not a sales pitch, and there is no charge for it. We will tell you what CMMC level you are really on, what the work involves, and whether we are the right fit. You do not need your scope figured out before you reach out. That part is the job.
