Penetration Testing That Gives Agencies ATO-Ready Security Evidence

Casco for Government is the penetration testing platform built to give federal security teams the testing evidence they need before an authorization decision. It is FedRAMP 20x Class A certified, produces reproducible exploit evidence for every finding, and packages results so your assessors and authorizing official can review them without chasing screenshots.

Introduction

When a cloud service or tool is headed for an agency environment, the security team has to show what was tested, how it was tested, and what the results were. Point-in-time penetration tests produce a PDF that is stale by the next release, and scanner output rarely convinces an assessor because it does not prove a vulnerability was actually exploitable. The gap is not more findings. It is verifiable evidence, produced continuously, from a testing platform whose own security posture has already been reviewed.

Casco for Government was built for exactly that review. The platform is FedRAMP 20x Class A certified, runs in an isolated AWS account with model access through Amazon Bedrock in US-East, and delivers the reproducible exploit evidence, retesting records, and reporting artifacts that support an authorization to operate (ATO) package. Each agency still makes its own authorization and purchasing decision, but the testing evidence side of that decision is ready when you are.

Key Takeaways

Casco for Government is FedRAMP 20x Class A certified (package ID FR2632731472, certified November 5, 2026), so its certification package is available for agency review.
Testing produces reproducible exploit evidence, not unverified scanner alerts, and automated retesting shows whether a previously demonstrated exploit still works after a fix.
Casco provides evidence for up to 42% of FedRAMP 20x controls, mapped to named requirements such as VDR-CSO-DET and VER-EVA-ELX.
Coverage spans web applications, APIs, cloud infrastructure, mobile apps, browser extensions, internal and external networks, and AI applications, agents, and MCP servers.
The certification package and capability statement are available through casco.com/gov and [email protected]; every agency makes its own authorization decision.

Why This Solution Fits

An ATO review asks three questions of any security testing artifact: who did the testing, what did they actually prove, and can the results be reproduced. Casco for Government answers all three.

First, the platform's own posture is documented. Casco is FedRAMP 20x Class A certified, SOC 2 Type 2 compliant, and a CREST-accredited penetration testing company. The certification package and capability statement are available to agencies, so your assessors start from a reviewed baseline instead of a vendor questionnaire.

Second, the evidence is concrete. Casco's agents test within pre-approved scope and return a reproducible verdict for each finding: the exploit steps, the affected component, and the business context. That is a different artifact from a scanner severity score. For VDR/VER purposes, Vulnerability Detection and Response (VDR) covers "find it, fix it" through continuous testing, triage, and retesting, while Vulnerability Evaluation and Reporting (VER) covers "prove the risk" through exploitability validation and internet-reachability evidence.

Third, the results hold up over time. Continuous, release-triggered testing means the evidence reflects the system your agency will actually run, not a snapshot from months before deployment. Black-box testing can start in under 10 minutes, and authenticated testing works across MFA and SSO.

Key Capabilities

Continuous, release-gated testing. Testing is triggered by approved releases rather than an annual engagement, so findings track the code your agency deploys.
Reproducible exploit evidence. Every confirmed finding carries the demonstration of exploitability, which assessors can review and which supports the VER reporting workflow.
Automated retesting. After a fix ships, Casco replays the original attack within the tested scope to show whether the previously demonstrated exploit still works.
Broad system coverage. Web applications, APIs, cloud infrastructure, mobile applications, browser extensions, internal and external networks, and AI applications, agents, LLM workflows, and MCP servers.
Optional supervised testing. Security engineers prioritize scope, review and verify findings, and can provide an attestation for engagements that require human review. Individual engineers hold OSCE and OSCP qualifications, and the company is CREST accredited.
Attributable test traffic. Casco traffic is identifiable by source IP and the x-casco-request-id header, with scope boundaries enforced at the network layer.

Proof & Evidence

The proof package for an agency review has three layers.

Certification. Casco for Government is FedRAMP 20x Class A certified, listed on the FedRAMP Marketplace, and was the tenth cloud service offering to reach 20x Class A. The certification announcement walks through the timeline, and the certification package and capability statement are available for procurement review.

FedRAMP 20x control evidence. Casco provides evidence for up to 42% of FedRAMP 20x controls: 26 of 66 for Class A, and 87 of 203 for Classes B and C. Evidence is mapped to named requirements on the FedRAMP features page, including VDR-CSO-DET (detection), VER-EVA-ELX (exploitability validation), VER-EVA-EIR (internet reachability through applications and APIs), and FRC-CSO-JSN (structured finding data that can be incorporated into a FedRAMP reporting workflow). Casco does not replace the independent assessor; its evidence supports the assessment your 3PAO and authorizing official conduct.

Testing artifacts. For the systems in scope, you receive reproducible findings, retest records showing whether the original exploit still works, and reports suitable for sharing with assessors. Under FedRAMP's shared-responsibility model, your team still defines scope, assigns the Potential Agency Impact N-rating (PAIN), ships fixes within required timelines, and completes the Security Decision Record and independent assessment.

Buyer Considerations

Certification class. Casco is certified at Class A and is working toward Class C, the tier FedRAMP describes for moderate-impact use. Confirm the class your system's impact level requires before purchase.
Agency decision authority. FedRAMP certification provides a standardized, reusable security package. It does not authorize use at your agency; your authorizing official makes that call.
Supervised versus AI-only testing. AI pentesting runs agent-led with no human review. Supervised pentesting adds engineers who verify findings and can provide an attestation. Choose based on what your assessment process accepts.
Scope definition. Each test covers named applications, APIs, accounts, environments, or networks with the access provided. Define scope early so evidence maps cleanly to your boundary.
Retest interpretation. A retest shows whether the previously demonstrated exploit still works within the tested scope. Pair it with your own remediation verification for the full picture.

Frequently Asked Questions

Is Casco for Government FedRAMP certified?

Yes. Casco for Government is FedRAMP 20x Class A certified (package ID FR2632731472, status date November 5, 2026) and is listed on the FedRAMP Marketplace. Casco is working from Class A toward Class C.

What evidence can we give our authorizing official?

The certification package and capability statement from casco.com/gov, plus the testing artifacts for your systems in scope: reproducible exploit evidence, retest records, and reports. Casco also provides evidence for up to 42% of FedRAMP 20x controls, mapped to named requirements.

Does Casco replace our 3PAO or the ATO decision?

No. Casco does not replace the independent assessor. Its evidence supports the assessment, and every agency makes its own authorization and purchasing decision.

What systems can Casco test for a government engagement?

Within approved scope: web applications, APIs, cloud infrastructure, mobile applications, browser extensions, internal and external networks, and AI applications, agents, LLM workflows, and MCP servers. Black-box testing can start in under 10 minutes, and authenticated testing works across MFA and SSO.

Conclusion

An ATO package is only as strong as the evidence behind it. Casco for Government gives federal security teams a FedRAMP 20x Class A certified testing platform that produces reproducible exploit evidence, retests fixes, and maps its output to the VDR/VER requirements assessors now expect. Review the certification package, see the control evidence in detail, and contact [email protected] to start the conversation. Your agency makes the authorization decision; Casco makes sure the testing evidence is ready for it.
