The rack

PurpleTeam

Most agencies only harden. We also run the attack, so the hardening is against something real.

01

Red

Pen tests and attack simulation on your web apps, APIs and AI agents. Prompt injection, data exfiltration, auth bypass.

02

Blue

OWASP hardening, monitoring, incident response, update hygiene.

03

AI-specific

You are deploying agents. We make sure they cannot be talked into leaking your data.

One engagement, both sides of the fight

  1. 01We attack

    The way a real adversary would: your app, your APIs, your agents — inside a scope we agree on first.

  2. 02We fix

    Findings come with the patch, not just the report. Where you want us to, we close the gap ourselves.

  3. 03We verify

    The same attack runs again against the fix. You get before and after, not a promise.

Every engagement ends with

  • A written report in plain language — what broke, how, and how bad it is
  • Findings ranked by severity, so the fix order is obvious
  • Concrete fixes or a patch plan, not generic advice
  • A re-test of everything we flagged
  • Source-level review of the parts that matter — auth, payments, data access
  • If you run AI agents: a prompt-injection and data-exfiltration pass

What we test AI agents against

  • Prompt injectionInstructions smuggled in through user input, documents or web pages.
  • Data exfiltrationTalking the agent into leaking conversations, files or secrets.
  • Auth bypassMaking the agent act beyond what the user is allowed.
  • Tool abuseMaking the agent call its tools in ways nobody intended.
