Multi-Agent Orchestration: Teams of AI pentesters collaborate on reconnaissance, exploitation, and validation and scale across large surfaces.
Developer-First CLI: Actionable findings surfaced through a command-line interface with concrete remediation guidance for engineers.
CI/CD Integration: GitHub Actions and pipeline integration to automatically scan every pull request and block insecure code before it reaches production.
Auto-Fix and Compliance Reports: Generates suggested patches and produces compliance-ready pentest reports for auditors and customers.

Application Security Testing: Detect and validate critical vulnerabilities in web and API applications during development.
Rapid Penetration Testing: Complete pentests in hours instead of weeks and produce compliance-ready reports for SOC 2, ISO, or PCI.
Bug Bounty Automation: Automate reconnaissance and PoC generation to accelerate bug-bounty research and reporting.
