Editorial Verdict
Best for
Security-conscious startups needing fast, continuous pentestingEnterprise teams requiring year-round compliance-ready security testingPlatforms handling sensitive data (e.g., health records, PII) that need HIPAA-level assuranceCompanies using AI systems (LLMs, agents) that need specialized security testing
Not ideal for
Teams seeking a free or low-cost scanning tool (pricing is contact-only)Organizations that require manual-only pentesting without automationBeginners without security knowledge to interpret reports (reports are detailed but require intermediate skill)Projects with a need for on-premises or air-gapped deployment
Casco is a strong choice for teams needing continuous, autonomous penetration testing. Its CREST accreditation, OWASP sponsorship, and proven track record with FAANG-approved pentesting make it a serious alternative to traditional human testers. However, the lack of public pricing is a hurdle; contact sales for a quote. For budget-conscious teams, consider open-source tools like OWASP ZAP or Burp Suite.

About Casco
Contact SalesIntermediateNo APIWeb · API
Casco provides continuous, autonomous security testing for modern applications, covering web apps, APIs, infrastructure, and AI systems. It scans for vulnerabilities year-round, outperforming traditional penetration testers by finding critical issues in hours that others miss for months. The platform integrates into development workflows and delivers clear, actionable reports with full context, business impact, and step-by-step reproduction. Human supervision is optionally available. Casco recently achieved CREST accreditation, underscoring its quality commitment. It is trusted by 300+ companies and is a Gold Sponsor of OWASP. Pricing is contact-based.
Behind the Verdict
Casco fills a clear gap: year-round security testing without the wait times and high cost of traditional penetration testers. Its autonomous scanning covers web apps, APIs, cloud, and AI systems, with specific attention to AI vulnerabilities like LLM data leakage and MCP tool poisoning. The platform produces reports that include full reproduction steps and business impact, which is valuable for compliance and developer remediation. One-click retesting after fixes is a standout feature. The company is transparent about its findings, as shown by its recent disclosure of a database takeover vulnerability in ElectricSQL. However, the pricing model is opaque — you must book a demo to get a quote, which may deter smaller teams. The tool is not designed for on-premises or air-gapped deployments, which may limit its use in highly regulated environments. Overall, Casco is a premium solution for security-conscious organizations that can afford it.

Integrations
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 contact-based pricing is suitable for mid-market and enterprise teams that already budget for annual pentests. Compared to traditional pentesting firms charging $10k+ per engagement, Casco can be more cost-effective for year-round coverage. However, small startups or solo developers may find it prohibitively expensive.
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 CI/CD integration: 30 minutes to set up using GitHub or GitLab. For a one-time full-site scan: a few hours to configure target URLs and authentication. For complex enterprise environments: 1-2 days with support from Casco's team.
