Free pentest / 15-team cohort

Put Apex against the attack surface you worry about most

Apex is Cantina's autonomous OffSec agent. It investigates your attack surface, validates exploitable paths, and helps close the security loop by verifying that the fixes hold.

From first signal to verified fix

The pentest closes the loop

The pentest carries context from investigation through remediation, then verifies each fix against the original attack path.

  1. 01

    Investigate

    Apex maps the attack surface, identities, application behavior, and reachable paths.

  2. 02

    Validate

    Apex follows promising paths until it can prove impact or close the lead.

  3. 03

    Fix

    Your team receives a targeted fix or fix-ready remediation inside the scope you approve.

  4. 04

    Verify

    Apex retests the same path and records whether the vulnerability is closed.

A fit for the cohort

Bring a real attack surface

This cohort works best when you can define the target and assign an engineer to carry validated findings through the fix.

  • 01 A defined application, API, or running service
  • 02 Written authorization for the agreed test surface
  • 03 An engineering owner ready to work through findings

Cantina is the first platform we have used that carries the work through from finding an issue to driving the fix, and it lets my team operate like one far larger than it is.
