Contracts depend on your CMMC certification. Your certification depends on the evidence.
CMMC Level 2 incident response controls require evidence of a live, practiced exercise, not just a documented plan.
What if the entire exercise, from scenario to assessor-ready report, took less than 60 minutes? You could run it this week.

Why now
The cost of getting it wrong
The assessment finding isn't a remediation plan. It's a failed certification. A failed certification means the contract goes to someone else. For many contractors in the DIB, that's more than a setback. It can be existential.
The clock is already running
CMMC Level 2 requirements are already appearing in new DoD contracts. From November 2026, it will be mandatory to get a C3PAO assessment before you can win work. IR testing is where many contractors find gaps. You have months, not years to close it.
Annual testing is the floor, not the ceiling
IR.L2-3.6.3 requires at least annual testing, but threat actors targeting CUI don't operate on your compliance calendar. Primes are increasingly expecting continuous readiness from their subs, not just annual compliance.
What your C3PAO assessor is looking for
3.6.1 requires an operational incident-handling capability. That means documented processes, defined roles, and a team that knows what to do when CUI is compromised. A C3PAO assessor won't just check the documentation. They'll look for evidence the capability is real and practiced, not just written down.
3.6.2 requires that incidents involving CUI are tracked, documented and reported to appropriate authorities. Your assessor will look for evidence that the right people know what to capture, when to escalate, and who to notify. A tabletop exercise is how you demonstrate that process has been rehearsed before it's needed.
3.6.3 is the testing control, and the one assessors check most directly. It requires the IR capability to be tested at least annually. A dated, named after-action report from a live exercise is what a C3PAO needs to mark this control as Met. Without it, the control is open regardless of how strong your documentation is.
Don't see your framework?
Handrails covers more than CMMC Level 2. If your framework is listed here, or you don't see it at all, let us know.
- FedRAMP (US)Cloud systems supporting federal agencies require IR testing as part of the ATO process. Also relevant for FISMA-obligated agencies and contractors under NIST SP 800-53 IR-3, and GovRAMP for state and local government.
- Essential Eight / DISP (AU)Australian government and defense suppliers face equivalent requirements.
- Cyber Essentials Plus (UK)UK government and MoD suppliers. Security posture assessment with overlapping IR expectations.
From scenario to C3PAO-ready report, in under 60 minutes.
Built around your context
Answer a few questions about your setup, including whether you're a prime or sub, your CUI scope, even upload your existing IR plan. The scenario is custom generated from your context, not pulled from a generic library.

Run it live, virtually
Your team joins a video call. A fictitious but realistic CUI incident unfolds. Each person makes the decisions they would actually make. The session is recorded. That recording is your evidence trail.
The report is ready before you close the call
A C3PAO-ready after-action report is generated from the session. Dated. Named. Mapped to IR.L2-3.6.1, 3.6.2 and 3.6.3. Hand it to your assessor, your prime or your contracting officer. Done.
Tailored, not templated
CUI exfiltration via compromised VPN
An engineer's creds are phished. The 72-hour DFARS 7012 clock starts. Who notifies DoD and with what?
Prime contractor flow-down breach
Your prime reports an incident. Your obligation to cooperate, preserve evidence and re-attest runs on a tight clock.
Quarterly mini: phishing to lateral movement
Short-form exercise satisfying the cadence CMMC recommends. 30 minutes, five roles, full evidence packet.
Turn flow-down obligations into a competitive advantage.
Under 32 CFR §170.23, primes must verify sub-contractor CMMC compliance before sharing CUI. The primes that get ahead of this don't just check the box. They give their subs a fast, affordable path to C3PAO-ready IR evidence, maintain visibility across the supply chain, and arrive at every contract with a compliant network already in place.
Make IR testing the easiest part of every CMMC engagement.
The C3PAO assessment is coming. Your IR evidence needs to be ready first.
Sign up, pick a scenario, invite the team. The report is ready before the session ends.
