What it is

What you're actually getting.

Most app security testing finds yesterday's bugs in a PDF nobody reads. We embed testing into your delivery pipeline so vulnerabilities are caught early, cheaply, and continuously.

Who it's for

Is this the right fit for you?

This is a good fit when…

  • Annual pentests find issues that should have been caught at PR time.
  • Your SAST/DAST tools generate noise and your engineers ignore them.
  • Real-world threats (auth abuse, business logic flaws) slip past every scanner you've tried.

You probably don't need this yet if…

  • Your product handles no sensitive data and isn't yet live.
  • You only need a one-off scan a free tool already provides.

How it works

A clear path from first call to launch.

  1. Threat model the application

    Before scanning, we model your attack surface. STRIDE or a lighter model , the goal is shared intuition about where the real risks live.

  2. Tooling tuned per repo

    SAST, DAST, SCA, IaC scanning , tuned to your codebase, with rule sets that don't produce noise. False positives are a backlog item, not a tax.

  3. Manual testing where it pays back

    Pentesters work the surfaces tools can't reach: business logic, authn/authz flows, multi-step abuse. The high-yield surfaces.
