What we test

What's covered

  • Access control & authorisation

    Can one user reach another's data or admin-only functions? We test every role against every endpoint.

  • Injection & input handling

    SQL injection, cross-site scripting (XSS), command injection and template injection across every input.

  • Authentication & sessions

    Login, password reset, multi-factor auth, session fixation and token handling.

  • Business logic

    Abuse of your app's own workflows — checkout tampering, price manipulation, workflow bypasses.

  • File uploads & document handling

    Malicious uploads, path traversal and unsafe document generation.

  • Configuration & exposure

    Security headers, error handling, exposed files and leaked information.

FAQ

Common questions

How much does a web application penetration test cost?

It depends on the size and complexity of the application — the number of pages, user roles and inputs. Most web application tests run from a few days. Use our instant estimate tool for a guide price, then we confirm the scope with you.

How long does a web app pen test take?

A typical web application test takes between three and six days of testing, depending on scope, plus reporting. We agree the timeline with you before we start.

Do you test staging or production?

Either. Many clients prefer a staging or UAT environment that mirrors production. We agree the target and rules of engagement up front.

What do we get at the end?

A report with an executive summary, each finding risk-rated with evidence and clear remediation advice, and a debrief with your team. We also offer a retest to confirm your fixes work.
