API security testing

APIs, or application programming interfaces, are omnipresent in modern web development. Service-oriented web applications are often built with a multitude of microservices that use APIs to communicate internally and exchange data with external systems. All those APIs expand your attack surface, so they need testing and securing just like all your other web assets—or you risk giving attackers an easy entry point for exploiting vulnerabilities in your applications and backend systems. Compounding this challenge further is the growth of vulnerabilities introduced by AI code assistants.

Shut the door to malicious hackers. Find, test and fix API vulnerabilities before they lead to a data breach. 

Find and test even the APIs you didn’t know about

Traditional dynamic vulnerability scanning often overlooks assets that a crawler can’t access and analyze, including unlinked or hidden files and (most importantly) unknown API endpoints. Adding to the server-side insights from its IAST sensor, Acunetix can now discover hidden and undocumented APIs, helping you systematically find, test, and secure APIs that were previously left off your security radar and greatly contributing to your overall risk.

Test your API endpoints for vulnerabilities

Adding API discovery findings to your known API definitions is a prerequisite for comprehensive testing. The next step is to put your APIs through detailed security checks to find exploitable vulnerabilities that you need to remediate. Acunetix provides in-depth vulnerability scanning for APIs alongside other application attack surfaces, supporting built-in security checks, definition imports, and discovery across REST, SOAP, and GraphQL—the three most popular API formats.

Embed API security testing into existing development workflows

Unlike with UIs, API updates and additions are often invisible outside of development, making it crucial to integrate API security tools into existing dev pipelines. Acunetix integrates out-of-the-box with popular tools like Jira and Jenkins to help you plug web application and API security testing right into your software development lifecycle (SDLC). Combined with good API inventory practices, this lets you test and retest all your endpoints automatically to catch vulnerabilities before they make it to production.

Run authenticated API scanning in a continuous process

The vast majority of production APIs require authentication, so testing them for vulnerabilities is only possible with authenticated scanning. Acunetix supports automated authentication for web applications and API endpoints alike to ensure your entire web attack surface is efficiently tested for vulnerabilities. API vulnerability scanning with Acunetix uses a wide array of mature security checks to deliver accurate and actionable results for prioritization and remediation.
