Casco provides autonomous security testing services for web applications, APIs, infrastructure, and AI systems. The platform performs continuous security assessments without requiring constant human intervention, though human supervision is available as an option. The company positions itself as an alternative to traditional penetration testing services, offering year-round security monitoring rather than periodic assessments. The platform identifies vulnerabilities and provides detailed findings that include business impact analysis, step-by-step reproduction instructions, and remediation recommendations. Reports include CVSS scoring and context about why vulnerabilities matter to the organization. The system includes one-click retest functionality to verify fixes. Casco serves companies ranging from enterprises to startups, with customers including organizations in various sectors. The company provides onboarding support through forward-deployed security engineers who tailor the implementation to each customer's technology stack. The service offers direct technical contact and guided walkthroughs of critical findings. The platform tests for various vulnerability types including authentication flaws, authorization issues, and AI-specific security concerns. The autonomous testing approach enables continuous security validation as code changes, rather than point-in-time assessments typical of traditional penetration testing engagements.
