API Penetration Testing

API Penetration Testing

APIs run the business.
Few ever get tested.

A deep, 49-module API security course β€” REST & GraphQL hacking, JWT and OAuth attacks, SSRF, CORS, XXE and automated API pentesting, mapped to the OWASP API Top 10.

Course positioning

Rarely tested. Rarely tested well.

APIs power most modern platforms but are rarely put through rigorous, dedicated security testing.

Without dedicated API testing

βœ• Testing stays limited to the web UI, not the underlying API.
βœ• JWT, OAuth and GraphQL-specific flaws go unchecked.
βœ• Excessive data exposure passes silently through responses.
βœ• No repeatable, automatable testing workflow.

Ignite's hands-on approach

βœ“ 49 modules covering REST, GraphQL, JWT, OAuth & OWASP API Top 10.
βœ“ Hands-on Postman & Burp Suite integration for real API traffic.
βœ“ GraphQL introspection, SSRF, CORS, XXE and template injection.
βœ“ Automated pentesting with Burp, ZAP, and CI/CD integration.
β€œI was nervous and filled with self-doubt. Despite trying various resources, I struggled to grasp the conceptsβ€”until I discovered Ignite Technologies.”— Kinjal Patel, verbatim Google review
