Details

What to expect from this engagement

What is included?

A practical API security assessment for product teams that depend on REST or GraphQL backends. I map documented and discovered endpoints, review token and authentication behavior, test object-level authorization, inspect sensitive data exposure, validate injection signals, and identify abuse paths that affect real users or business workflows.

Who is it for?

API-first companies, mobile backend teams, SaaS products, and developers preparing an API for production.

What do you need to provide?

Written authorization, API documentation when available, test credentials, target environment details, and expected user roles.
