Phoenix Security

Founded in London in 2020, Phoenix Security connects application code to production runtime so security teams can see which vulnerabilities are actually reachable and exploitable, rather than chasing every finding a scanner produces. The platform auto-assigns ownership to the right engineering teams, prioritises exposure using real-world context, and uses AI agents to drive opt-in fixes and remediation campaigns at scale, keeping humans in control of the final decision.

Phoenix Security has raised around $5.7M to date, backed by investors including Kerr Ventures and Founders Factory.
