Cloudflare API Shield

Identify and address your API vulnerabilities.
Enterprise-only paid add-on

​​ Why care about API security?

APIs have become the backbone of popular web services, helping the Internet become more accessible and useful.

As APIs have become more prevalent, however, so have their problems:

  • Many companies have thousands of APIs, including ones they do not even know about.
  • To support a large base of users, many APIs are protected by a negative security model that makes them vulnerable to credential-stuffing attacks and automated scanning tools.
  • With so many endpoints and users, it’s difficult to recognize brute-force attacks against specific endpoints.
  • Sophisticated attacks are even harder to recognize, often because even development teams are unaware of common and uncommon usage patterns.

Refer to the Get started guide to set up API Shield.
