⏚ Summary

What this engagement is, plainly.

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.

Problems we solve

  • 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.

⏚ Approach

How we run this engagement.

  1. 01Phase

    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. 02Phase

    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. 03Phase

    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.

⏚ Deliverables

What you get, signed off.

  • Threat model document

  • Tuned SAST + DAST + SCA pipeline

  • Manual penetration test + report

  • Remediation tracking + retest

  • Security regression test suite

⏚ Stack we typically use

Tools, not religion.

We pick on workload and team shape, not on fashion. Anything below is a default — swappable when your context demands.

  • Semgrep
  • CodeQL
  • OWASP ZAP
  • Burp
  • Snyk
  • Trivy

Outcome

Vulnerabilities caught at PR time, not pentest time. A security signal your engineers actually trust. Audit and compliance evidence as a side-effect.
