Service overview

Security expertise aligned with operational reality.

API risk often sits below the user interface. We test object authorization, function authorization, token handling, mass assignment, rate limits, shadow endpoints and data exposure across REST, GraphQL and integration APIs.

Reduced data exposureStronger tenant isolationSafer partner integrations

Core capabilities

Frameworks

OWASP API Security Top 10

Authorization, authentication, object properties, resource use and unsafe consumption reviewed against API risk categories.

Regression-friendly output

Where practical, findings can be translated into repeatable request collections for development teams.

Delivery model

Clear at every stage.

A structured approach keeps scope, communication and outcomes aligned throughout the engagement.

  1. 01

    Inventory APIs

    Build a working view of documented, observed and legacy endpoints across clients and integrations.
