Deep API Crawler

The Syhunt API scanner maps your entire API attack surface — all endpoints, methods, parameters, and data flows - and uncovers unique vulnerabilities by simulating a wide range of real-world attacks and sending thousands of crafted requests. The scanner offers full support for a variety of API specification formats such as API Blueprint, OpenAPI, Swagger, Postman Collections and beyond.

API Discovery & Management

• 

Continuously identify all APIs — including shadow, orphan, zombie, third-party, and AI endpoints — while maintaining a live inventory with vulnerability testing. Combines SAST, DAST, and log analysis for comprehensive discovery, and integrates seamlessly into CI/CD pipelines to track changes over time. The extension Syhunt API Plus (with API Discovery and Management) will be available by the start of 2026.

Code Analysis Extensions

• 
• 
• 

When used from within Syhunt Hybrid, the Syhunt API scanner is able to expand the scope of the API security testing, covering the API source code as well. Supported languages include ASP.NET Core (C#), Java, Node.js, PHP, Python & Ruby.
