Customer proof
Why teams keep Casco running.
Hear from the teams that put Casco against their real attack surface and brought the findings back to engineering.
“In a matter of hours, Casco was able to find critical vulnerabilities that our other pentesters couldn't find for months.”
Bryan Chappell, CEO of Scout
“In my 15 years working in cybersecurity, Casco is the first cybersecurity product that makes security testing high-quality, fast, and easy.”
Matthew Broom, Head of Security at CrewAI
“Casco is mission-critical for enterprise deals. We started the security assessment on a Friday and completed the procurement process by Monday.”
Saarth Shah, CEO of SixtyFour

03 / The deliverable
A pentest report that clears the toughest security reviews
Casco pentests have cleared procurement with Microsoft, Google, AMD, and Apple. Every Casco pentest can optionally include human review by OSCE, OSCP, CREST, and PCI-certified security engineers.
AI pentesting, explained
Frequently Asked Questions
Clear answers for security teams, engineering leaders, and anyone evaluating a modern pentest.
Ask about your scope01What is AI penetration testing?
AI penetration testing uses security agents to explore a running product, build a threat model, follow attack paths, and validate impact. Casco can add an offensive security engineer to guide the test and review findings when the scope calls for human supervision.
02How does Casco know what to test?
Casco first discovers your applications, infrastructure, and networks. It maps domains, endpoints, authentication, roles, tenant boundaries, services, and AI interfaces. Casco learns from your application context, customer workflows, documentation, and public-facing artifacts. It uses that context to build scenario-based tests around potential issues in your system.
03Does Casco prove that a finding is exploitable?
Yes. A finding includes the affected resource, reproduced impact, remediation guidance, and the code or request used to validate it. Human verification is available when your security or procurement process requires it.
04What does Casco test?
Casco tests approved web applications, APIs, cloud infrastructure, mobile applications, browser extensions, AI applications and agents, MCP servers, and internal or external networks.
05Is Casco safe to run against production?
Yes. Casco is safe to run against production. It operates only inside approved targets, accounts, time windows, and rules of engagement. It does not perform DDoS or resource-exhaustion attacks. Stable source IPs, per-request IDs, and network-level scope controls keep testing traceable and constrained. Read about Casco’s network-observability safeguards
06Can Casco test black-box applications?
Yes. Casco only needs a single application entry point to begin black-box testing. If your application is self-serve, Casco security testing agents can automatically sign up and begin testing authenticated workflows.
07Can Casco test grey-box applications?
Yes. Casco can use optional source code, cloud context, architecture details, documentation, and test credentials to make scenario-based testing more precise. Integrations are available for AWS, GCP, Railway, Buildkite, Jira, Linear, and GitHub.
08How does Casco test authenticated applications? Are there any restrictions?
Casco can pentest authenticated applications of all types. Its security testing agents have true identities, including their own email inboxes, phone numbers, and TOTP devices. This allows them to sign in to applications protected by MFA, magic links, Google SSO, and Microsoft Entra ID.
09How is Casco different from a scanner or annual pentest?
Scanners look for known patterns. Annual pentests capture one version of a product. Casco combines adaptive agents, retained application context, optional human review, and exact-attack retesting after releases and fixes. It can run 24/7.
10Can I use Casco for SOC 2 and ISO 27001?
Yes. A Casco pentest exceeds SOC 2 and ISO 27001 compliance standards.
11Can I use Casco for procurement?
Yes. Casco pentest reports have cleared security and procurement reviews at Microsoft, Google, AMD, and other major enterprises. Each report packages approved scope, reproduced impact, evidence, remediation guidance, and retest results for buyer and security-team review. Optional human verification is available when required.
12How quickly does Casco deliver results?
Casco delivers findings immediately as they are validated. If you require a human-approved pentest, Casco delivers it within five business days.
13How is Casco priced?
Casco’s pricing depends on scope and the frequency of product changes. Book a demo to learn more.
14What happens after a vulnerability is fixed?
You can configure Casco to automatically replay the original attack. The retest records when the finding is remediated.
