About

APX Security builds autonomous AI agents that perform offensive security testing the way an attacker would — probing APIs, crawling web applications, reversing mobile binaries and mapping networks. Rather than emitting scanner alerts, its agents chain findings into a working exploit and deliver reproducible proof that the vulnerability is real. The company ships two products: Cipher, a managed assessment of internet-facing applications, and Niro, continuous self-managed pentesting wired into the software development lifecycle. It was founded by Gaurav Singhal, who previously led security tooling across engineering teams at AWS.

Every finding comes with a chained, reproducible exploit as proof, which removes the false-positive triage burden that makes conventional scanner output expensive to act on.

Product

Cipher

AI-driven offensive security testing

A managed AI pentesting service for internet-facing applications: the agent maps the target, finds a vulnerability, chains it into an exploit and returns a verified report with reproducible proof.

  • AI agent that reasons like an attacker across APIs, web apps, mobile binaries and networks
  • Exploit chaining to prove a finding is genuinely exploitable
  • Verified reports with reproducible exploits

Built for

Security teams and engineering organizations with modern CI/CD pipelines and internet-facing applications
