Breachline is the world's first fully autonomous black-box pentesting platform. Its AI engine, Nebula, deploys specialist agents with a full offensive toolkit to discover, exploit, and report vulnerabilities without any human input. 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.

Careers at BreachLine Labs

Build the World's Most Advanced Hacking Intelligence

We're a small, ambitious team in London building Nebula -an autonomous black-box pentesting AI that thinks like a senior red teamer. We need people who hack, build, and ship. If that's you, keep reading.

Why us

Why BreachLine?

Ship Real Attacks

Your code goes into production Nebula. You will watch it chain exploits, pop shells, and find real vulnerabilities in real organizations.

London HQ, Remote-Friendly

Based in Great Portland Street, London. Work from the office, from home, or anywhere across the UK and EU. Your call.

Early-Stage Impact

Small team. No layers. Every person shapes the product, the culture, and the direction. You will not be a cog here.

Cutting-Edge Stack

LLMs, multi-agent swarms, Docker sandboxes, real-time exploit chains. If it sounds like a research paper, we are probably shipping it.

Open roles

Open Positions

Every role reports directly to the founders. No middle management, no ticket queues. You ship from day one.

Culture

What We Value

Hack first, ask later

We value hands-on security experience over credentials. Show us what you have broken, not what you have memorized.

Ship it

We move fast and iterate in production. Perfect is the enemy of deployed. Get it out, learn, improve.

Stay curious

The threat landscape changes daily. So should you. We hire people who read CVEs for fun and tinker on weekends.

General Application

Don't see your role?

We're especially interested in offensive security researchers, bug bounty hunters, red teamers, and anyone who has found vulnerabilities in real-world systems. If you have a terminal open right now, we should talk.
