GK Data provides web application and API penetration testing focused on the systems attackers actually touch: login flows, authorization checks, business logic, user-generated content, API endpoints, integrations, and the places where small assumptions create real exposure.
Testing is recon-heavy and manually validated. Custom AI agents may help organize assets, routes, and research notes, but findings are reproduced by hand before they go into a report.
What gets tested
- Authentication, session handling, password reset, and account recovery flows.
- Authorization issues such as IDOR, broken object-level access control, and tenant isolation failures.
- API behavior across REST, JSON, GraphQL-style patterns, CORS, rate limits, and data exposure.
- Injection and browser-side risk including XSS, HTML injection, SSRF, open redirects, and unsafe file handling.
- Business logic paths where the application behaves securely in code but incorrectly in the real workflow.
What you receive
Reports include clear reproduction steps, affected assets, evidence, business impact, recommended remediation, and retest notes when validation is included. The goal is useful engineering output, not a giant PDF no one wants to read.
