API security testing

Scan for API security vulnerabilities

More comprehensive scans. More vulnerabilities identified. More time saved. Enhance your API security with Burp Suite.

API security testing represented by a torch

API security is more important now than ever before

APIs are a vital component of modern web applications, but security in this area is often poorly implemented and maintained. Many web vulnerability scanners lack visibility when it comes to APIs, which means the organizations using them lack visibility too.

Burp Scanner's built-in API security testing functionality can help to solve this problem.

Improved visibility of APIs means more endpoints scanned

Burp Scanner allows you to scan your APIs as part of your wider web app crawl & audit, and as a standalone too.

Upload an API definition file directly to the Burp Scanner and test for vulnerabilities without the need to host your own API specification, easily identify whether you have left a hosted API that can be accessed by attackers, test a wider range of endpoints by including HTTP headers, and scan APIs that require authentication.

Because many organizations struggle to manage their APIs, Burp Scanner's API discovery and scanning capabilities can mean a real boost to attack surface visibility. What you can't see, you can't test - making visibility paramount in today's API-connected world.

Burp Scanner's API scanning capabilities are continually evolving

As with all Burp Suite features, API scanning is constantly evolving - enabling increased productivity and reliability for customers. Given the rising popularity of microservice architectures, and the need for fast, reliable API security testing tools, Burp Scanner will be introducing enhanced API security features in each release.

These enhancements will include exciting changes to the way Burp Scanner detects and scans APIs. You can find out more about upcoming plans for API scanning in our blog.
