Casco
AI penetration testing platform that continuously tests web apps, APIs, cloud, and AI systems, proving exploitable paths and retesting every fix.
Casco is the closest thing to a permanent pentester, with continuous, evidence-based AI testing and a rare FedRAMP listing. Its Slack bot and MCP integration make it unusually developer-friendly. However, pricing is contact-only and there's no free tier, so smaller teams may hit a wall; compare with Pentester.io or HackerOne if you need cost certainty or a lighter lift.

Skip Casco if you need a free, self-serve scanner with transparent pricing, or if your environment requires on-premises deployment and you lack the budget or willingness to engage in a sales cycle.
Casco's pricing is contact-only, so you won't see actual costs until you book a demo—expected to be enterprise-level.
Casco's pricing is bespoke and tailored to mid-market and enterprise customers. It's likely more expensive than self-serve scanners like Nessus or OpenVAS, but competitive with premium pentest services. For companies needing FedRAMP-listed, continuous testing, the value justifies the cost—compare with Pentester.io for a more transparent per-test model.

About Casco
Casco is an AI penetration testing platform that replaces annual pentests with continuous, always-on autonomous security testing. It maps your live attack surface—web applications, APIs, cloud infrastructure, mobile apps, browser extensions, and AI systems—and uses AI agents to probe authenticated workflows and prove exploitable paths. Every finding ships with reproducible evidence: the affected resource, impacted business context (like PII exposure or HIPAA violations), and step-by-step reproduction and remediation guidance. Designed for development speed, Casco triggers tests on every approved release, retaining attack context and replaying the attacks that matter. A one-click retest replays the proven exploit to verify fixes without waiting on human testers. Recent releases have added a Slack bot (July 2026) for pentest alerts and Q&A, MCP integration (July 2026) for agentic workflows, and improved network observability (July 2026) to make every request attributable and reviewable. Casco integrates with GitHub, GitLab, CircleCI, Jenkins, AWS, GCP, Railway, Buildkite, Jira, and Linear, so security checks run with every deploy and findings route to the team that owns the fix. Now serving 400+ customers—including Scout, CrewAI, and SixtyFour—Casco has cleared procurement with major enterprises including Microsoft, Google, AMD, and Apple. Its pentests optionally include human review by OSCE, OSCP, CREST, and PCI-certified engineers. Casco holds CREST accreditation, is an OWASP Gold Sponsor, and recently raised a $100M Series A (July 2026). Notably, Casco is the first standalone FedRAMP-listed agentic offensive security platform.
Behind the Verdict
Casco's main strength is continuous, evidence-based security testing. Unlike static scanners that start from scratch each run, Casco retains attack context and replays proven attacks, providing reproducible proof rather than point-in-time narratives. The platform's coverage is broad—web apps, APIs, cloud, AI systems—and its authenticated testing with real identities (email, phone, TOTP) makes it realistic. The 2026 updates enhance workflow integration: the Slack bot brings alerts and Q&A into chat, the MCP integration lets AI agents trigger tests, and improved observability attributes every request. These features make Casco a strong fit for engineering teams that want security woven into their daily workflow. However, Casco requires commitment: pricing is contact-only, with no transparent tiers or free trial, which may deter small teams or individual developers. On-premises deployment is not mentioned, so air-gapped environments might not be supported. Additionally, while Casco is agentic, complex scenarios may still benefit from human review, which could come at an extra cost. For organizations needing full manual testing or those without in-house security expertise, a traditional pentest or a managed service might be simpler to digest.

Where the pricing makes sense
The company stage and team size where Casco's pricing actually pencils out — and where peers do it cheaper.
Casco's pricing is bespoke and tailored to mid-market and enterprise customers. It's likely more expensive than self-serve scanners like Nessus or OpenVAS, but competitive with premium pentest services. For companies needing FedRAMP-listed, continuous testing, the value justifies the cost—compare with Pentester.io for a more transparent per-test model.
Setup time & first value
How long it actually takes to get something useful out of Casco — broken out by persona, not the marketing-page minute.
For a straightforward web app: connect your repo and cloud, and Casco can start testing within hours. CI/CD integration takes a day. Full enterprise onboarding with SSO and custom integrations may take 1–2 weeks, depending on scope.
Switching to or from Casco
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From automated scanners (e.g., Nessus, Qualys): Casco provides continuous, authenticated testing with proven exploit paths, replacing periodic scans.
- →From traditional pentest firms: Casco offers continuous coverage, but you may need to adapt to the autonomous workflow and evidence-based reporting.
- ↗To Pentester.io or HackerOne: If you need transparent pricing or a pay-per-finding model, export Casco's evidence and reports to hand off.
- ↗To an internal security team: Export all findings and context to build your own testing infrastructure.
