Your APIs outnumber your pages — attackers noticed

Modern products expose more logic through APIs than through any UI, and API flaws — broken object-level authorization, mass assignment, unbounded queries — don't show up in web scans. We test APIs the way they're attacked: as programmable business logic.

API breaches are quiet and complete: no browser, no alarms, just enumerable IDs and data leaving at machine speed. By the time misuse shows in metrics, the dataset is already gone.

What we do

Authorization testing

Object-level and function-level access control probed across every role and tenant boundary — the flaw class behind most real API breaches.

Input & injection testing

Injection classes, deserialization, and schema-validation gaps across REST, GraphQL, and event endpoints.

Business-logic abuse

Rate limits, workflow bypasses, replay, and enumeration — the attacks that are legal HTTP and illegal business.

Auth & session review

Token handling, JWT validation, key management, and session lifecycle — where one mistake is total compromise.

How it’s delivered

  1. 01

    Map

    API inventory from specs and traffic — including shadow endpoints.

  2. 02

    Test

    Manual assessment aligned to the OWASP API Security Top 10.

  3. 03

    Report

    Findings with working repro requests.

  4. 04

    Retest

    Fix verification, updated report.

Tools & standards

Tooling
Burp Suite Pro, OWASP ZAP, Postman, custom harnesses
Methodology
OWASP API Security Top 10; PTES-aligned reporting

What you receive

  • Endpoint-mapped findings with reproduction requests
  • Authorization-matrix results across roles and tenants
  • Remediation guidance your API team can apply directly
  • Retest verification

Evidence

300+ APIs, one program

We ran a structured security assessment across 300+ endpoints — authentication, authorization, rate limiting, and injection classes — with findings ranked by exploitability.

Who this is for

  • Platform teams whose public API is the product
  • Companies whose last web pentest barely touched the API surface
  • Teams shipping mobile or partner integrations backed by shared APIs
