Your web application is your front door

We test your web applications and APIs the way a real attacker would — authentication, authorisation, business logic, and the API endpoints your mobile app quietly depends on — then show your developers exactly how to fix what we find.

What this covers

  • OWASP Top 10 coverage, tested rather than scanned
  • Authentication, session handling and account recovery flows
  • Authorisation flaws including IDOR and broken object-level access
  • Business logic and workflow abuse that scanners cannot see
  • REST, GraphQL, webhook and third-party integration testing
  • Injection classes, SSRF, file upload and deserialisation
  • Client-side issues: XSS, CSRF, DOM and postMessage abuse
  • Rate limiting, enumeration and abuse-resistance review

Questions about web app testing

Usually yes, because that is where the real configuration and real data live — staging environments often have different rules and different mistakes. We agree scope and any off-limits functionality in writing first, and we run anything with a risk of disruption outside business hours.

Always. In most modern applications the API is where the actual risk sits, and a large share of the serious findings we report are API-only — reachable without ever loading the web interface. If we can find documentation or a mobile build, we will map the full surface before we start.

No, and anyone who says otherwise is selling you something. A test is a time-boxed sample of your attack surface carried out by fallible humans. What we can promise is that we will tell you exactly what we covered, what we did not, and where you should look next.

A 30-minute call, no pitch deck. We will tell you whether we are the right fit — and if we are not, we will point you somewhere better.
