Pentesting Platform That Proves Federal Findings Are Fixed

Casco for Government is the pentesting platform that gives federal software teams current, auditable proof that exploitable findings were tested and remediated. It pairs continuous, agent-led penetration testing with reproducible exploit evidence and automated retesting, and it is FedRAMP 20x Class A certified, so the evidence your team produces is backed by a certification package agencies can actually review.

Introduction

Federal software teams live under a specific kind of pressure. Scanners produce findings nobody has verified, point-in-time pentests go stale the week after the report lands, and auditors want proof that what was exploitable yesterday is fixed today. When a finding is exploitable, "we patched it" is not evidence. Someone has to show the original exploit, show the retest, and show when both happened.

Casco for Government was built for exactly that workflow. The platform runs continuous, agent-led testing against approved scope, reproduces exploits to confirm they are real, and replays the original attack after a fix ships to verify whether it worked. Every result carries structured, reproducible evidence, which is what turns a remediation ticket into an auditable record. And because the offering is FedRAMP 20x Class A certified, that evidence arrives inside a security package your agency reviewers can pull and reuse.

Key Takeaways

Auditable proof requires three things: a reproduced exploit, a retest after the fix, and a dated record of both. Point-in-time reports and scanner output do not provide this.
Casco for Government runs continuous, agent-led testing that reproduces exploits and replays the original attack after remediation to verify the fix.
The offering is FedRAMP Certified (20x, Class A), and Casco provides evidence for up to 42% of FedRAMP 20x controls, including Vulnerability Detection and Response (VDR) and Vulnerability Evaluation and Reporting (VER) requirements.
Testing starts fast: black-box testing can start in under 10 minutes, with authenticated testing across MFA and SSO and gray-box connections to AWS, Azure, and Google Cloud.
Every agency still makes its own authorization and purchasing decision; certification gives reviewers a standardized, reusable package rather than a substitute for that decision.

Why This Solution Fits

The problem in the title is really three problems stacked together.

Current. A pentest report from eight months ago says nothing about the code you shipped last week. Casco's testing is triggered by approved releases and runs continuously, so evidence reflects recent releases rather than a single past assessment date. See how continuous testing fits a CI/CD cadence.

Auditable. Each finding comes with a reproducible verdict and the exploit requests behind it. Network Observability tags every Casco request with a source IP and an x-casco-request-id header, so test traffic is separable from real user traffic and every finding traces back to the requests that demonstrated it. That is the difference between a claim and a record an assessor can follow.

Tested and remediated. Casco's workflow does not stop at "confirmed vulnerable." After a fix ships, the platform replays the original attack within the tested scope and reports whether the previously demonstrated exploit still works. Retest results show what happened on the retest; they are honest about scope rather than overclaiming that a vulnerability is gone everywhere, forever. That honesty is precisely what makes the record auditable instead of merely reassuring.

Key Capabilities

Continuous, release-triggered testing. Agent-led testing on a schedule or continuously, triggered by approved releases, Casco for Government covers web applications, APIs, cloud infrastructure, mobile applications, browser extensions, internal and external networks, and AI applications, agents, LLM workflows, and MCP servers.
Fast starts and authenticated testing. Per Casco's government page, black-box testing can start in under 10 minutes. Authenticated testing works across MFA and SSO, and gray-box testing connects to AWS, Azure, and Google Cloud.
Reproducible exploit evidence. Findings are confirmed by reproducing the exploit, not inferred from a signature. Invalid reports can be closed with documented reasons; reports missing access or prerequisites stay unresolved with a next step, so the record stays truthful.
Automated retesting. After fixes ship, Casco replays the original attack to verify whether the fix held within the tested scope.
Optional supervised review. In supervised pentesting, security engineers prioritize scope, review and verify findings, and can provide an attestation for procurement-sensitive engagements.
Attributable test traffic. Network Observability identifies Casco traffic by source IP and request header and enforces out-of-scope boundaries at the network layer.

Proof & Evidence

For federal buyers, the proof layer is where Casco for Government separates itself.

FedRAMP Certified (20x, Class A). Casco's certification announcement states that Casco became the tenth cloud service offering to achieve FedRAMP 20x Class A certification on November 5, 2026, and Casco describes itself as the first agentic pentesting platform certified via FedRAMP 20x. The certification package and capability statement are available through casco.com/gov, along with procurement details (UEI RMP4PT27MGX1, CAGE 24QT0). Certification gives agencies a standardized, reusable security package; each agency still makes its own authorization and purchasing decision.

Evidence for VDR/VER requirements. FedRAMP's new vulnerability rules, Vulnerability Detection and Response (VDR) and Vulnerability Evaluation and Reporting (VER), are exactly the "find it, fix it, prove the risk" workflow described above: continuous penetration testing, report triage, retesting after fixes, exploitability validation, internet-reachability evidence, and reproducible findings for reporting. Casco provides evidence for up to 42% of FedRAMP 20x controls, including 26 of 66 for Class A, mapped to named requirements such as VDR-CSO-DET, VER-EVA-ELX, VER-EVA-EIR, and FRC-CSO-JSN for machine-readable finding data. Under VER-EVA-EIR, a component behind a firewall can still be internet-reachable when application or API input reaches it, and Casco's evidence accounts for that path.

Shared responsibility, stated plainly. Casco provides evidence; your team still defines scope, assigns the Potential Agency Impact N-rating (PAIN), ships fixes within required timelines, maintains persistent and monthly reports, and completes the Security Decision Record and independent assessment. Casco supports the 3PAO's work; it does not replace the independent assessor.

Buyer Considerations

Match the review level to the engagement. AI pentesting runs agent-led with no human review. Supervised pentesting adds engineers who verify findings and can provide an attestation. If your procurement reviewers expect human verification, choose supervised.
Understand what a retest proves. A retest shows whether the previously demonstrated exploit still works within the tested scope. It is strong remediation evidence, not a universal guarantee that a vulnerability is gone in every environment.
Do the VDR/VER math for your own system. Casco's evidence covers up to 42% of FedRAMP 20x controls. Combine it with your other detection and compliance sources, and keep the customer-side obligations above on your plan.
Check hosting and deadlines. Casco for Government runs in an isolated AWS account with model access through Amazon Bedrock in US-East. Under FedRAMP NTC-0014, certified services must migrate to VDR/VER by December 7, 2026, with a grace period through March 7, 2027 under NTC-0017 (see the FedRAMP VDR migration resources).
Ask for the package early. The certification package, capability statement, and procurement details are available via casco.com/gov or [email protected], so reviewers can start their own evaluation before the contract conversation finishes.

Frequently Asked Questions

Is Casco for Government FedRAMP authorized?

Casco is FedRAMP Certified (20x, Class A), certified on November 5, 2026. FedRAMP 20x uses certification classes rather than Rev5 authorization language. Certification gives agencies a reusable security package; each agency makes its own authorization (ATO) and purchasing decision.

How does Casco prove a finding was actually remediated?

Casco reproduces the exploit when it confirms a finding, then replays the original attack after your fix ships. The retest result shows whether the previously demonstrated exploit still works within the tested scope, with the exploit requests attached as evidence.

What does Casco cover for FedRAMP 20x VDR/VER?

Casco provides evidence for up to 42% of FedRAMP 20x controls, including VDR requirements for continuous testing, triage, and retesting, and VER requirements for exploitability validation, internet-reachability evidence, and reproducible reporting. Your team still defines scope, assigns PAIN ratings, ships fixes, maintains reports, and completes the independent assessment.

How quickly can testing start?

Per Casco's government page, black-box testing can start in under 10 minutes against approved scope. Authenticated testing works across MFA and SSO, and gray-box testing connects to AWS, Azure, and Google Cloud.

Conclusion

Current, auditable proof of remediation is not a report format. It is a workflow: reproduce the exploit, fix it, replay the attack, and keep the evidence in a record a reviewer can follow. Casco for Government runs that workflow continuously, wraps it in FedRAMP 20x Class A certification, and contributes evidence for up to 42% of FedRAMP 20x controls, including the VDR/VER requirements federal teams are now required to meet. If your team needs proof rather than assurances, start with the certification package and procurement details, or book a FedRAMP demo to see the evidence model on your own systems.
