WEB/API

Web Application & API Penetration Testing

Manual, attacker-driven testing of your web applications and APIs — from authentication and access control to the business-logic flaws automated scanners can't see.

What we test

  • Broken access control — IDOR / BOLA, privilege escalation and multi-tenant isolation
  • Authentication, session management, MFA and SSO / OAuth 2.0 / OIDC flows
  • Injection — SQL & NoSQL, OS command, SSTI and XXE
  • Client-side attacks — XSS, CSRF, CORS misconfiguration, postMessage and clickjacking
  • Server-side request forgery (SSRF) and cloud-metadata exposure
  • Business-logic abuse — payments, workflows, coupons and race conditions
  • REST, GraphQL and gRPC APIs — mass assignment, rate limiting and schema exposure
  • File uploads, insecure deserialization and vulnerable third-party components

A strong fit for

  • SaaS platforms preparing for SOC 2 or ISO 27001 audits
  • Fintech, e-commerce and products that handle personal data
  • Major releases, new APIs and customer security questionnaires

How the engagement runs

  1. Scope & rules of engagement

    A short call to understand your architecture, risks and goals. You receive a fixed-price proposal and written rules of engagement.

  2. Reconnaissance & threat modeling

    We map your attack surface — endpoints, roles, integrations and trust boundaries — and decide where an attacker would strike first.

  3. Manual exploitation

    Hands-on testing beyond checklists: chaining weaknesses, abusing business logic and proving real impact — safely.

  4. Report & debrief

    A prioritized report with executive summary, technical findings, proof of concept and remediation guidance — walked through with your team.

  5. Retest & attestation

    After you fix, we verify every remediation and issue an updated report and a letter of attestation for customers and auditors.
