Breachline is an autonomous AI penetration testing platform backed by a UK offensive security team. Its AI engine, Nebula, uses multiple reasoning models and a swarm of specialist agents to discover, exploit, and verify vulnerabilities, with every finding backed by real tool output and a working proof-of-concept. It delivers compliance-ready reports mapped to PCI-DSS 4.0, SOC 2, HIPAA, ISO 27001, OWASP Top 10, and NIST CSF.

How does autonomous pentesting work?

Nebula AI follows a multi-phase autonomous attack lifecycle: (1) Planning - classifies target and assembles optimal agent team, (2) Recon - runs tools in parallel to map attack surface, (3) Analysis - specialist agents test every vulnerability class with MITRE ATT&CK mapping, (4) Exploit - builds working PoC exploits in sandboxed containers, (5) Report - delivers executive summaries and technical deep-dives to Slack and email instantly.

What compliance frameworks does Breachline support?

Breachline automatically maps findings to 6 compliance frameworks: PCI-DSS 4.0, HIPAA, SOC 2 Type II, ISO 27001, OWASP Top 10, and NIST CSF with specific control IDs. Reports are audit-ready and delivered instantly via Slack and email.

Is Breachline safe to use on production systems?

Yes. Nebula runs all exploits in isolated Docker containers with fresh network namespaces. Containers self-destruct after each test, leaving zero artifacts on your infrastructure.
