Web Application and API Penetration Testing

We attack your web apps and APIs the way real attackers do, to find logic flaws, access control gaps and data exposure that scanners miss.

All services

// Overview

What this service is.

Application and API testing simulates attacks against application logic, interfaces and supporting services. We focus on weaknesses that could lead to unauthorized access, data exposure, privilege escalation or abuse of business functionality.

Testing can be performed with or without credentials and can cover both anonymous and authenticated user scenarios, including multiple roles, so we can show how an attacker could bypass authentication or authorization.

// Questions

Frequently asked questions.

Can you test APIs without documentation?

Yes, though documentation or collections speed things up and improve coverage. We will agree the approach during scoping.

Do you test authenticated flows?

Yes. We recommend testing with several user roles to find access control problems.

Will this help with customer security questionnaires?

Yes. A third-party penetration test report is commonly requested by customers and auditors.
