What it is

What you are 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.

The result XpansionIT delivers for Application Security Testing.

Who it is 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 do not 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. 01

    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. 02

    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. 03

    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.

What you gain

The outcomes that matter to your business.

  • Security flaws caught at build time, not after a breach.
  • A clear, prioritised list of real risks with fixes confirmed.
  • Evidence of your security posture, ready for clients and auditors.

What is included, signed off.
