Why is API scanning important?​

APIs are now a critical part of most mobile, SaaS and web applications. But as more organizations build APIs to increase automation and improve performance, the attack surface for hackers is growing.

Knowing where your APIs are, and understanding how attackers can exploit them, is more important than ever. Regular API scanning helps to secure your application by identifying weaknesses so you can fix them before they're exploited.

I really like how Intruder integrated with our internal company comms (ie Slack), this meant we stayed on top of the notifications it produced. Time is critical when it comes to security vulns so it’s helpful to have messages from Intruder next to our daily workflows.

Frequently asked questions

What is API security?

API security refers to the processes required to protect APIs from cyber attacks. This typically includes the use of an API scanner to detect weaknesses that could be exploited by attackers.

How does Intruder scan APIs?

Intruder conducts authenticated or unauthenticated vulnerability scans for APIs with 1:1 mapping using the OpenAPI or Swagger protocols. Simply upload your OpenAPI/Swagger schema to start running automated checks for security weaknesses.

Which plan do I need to scan APIs?

To start scanning your APIs you need an Application License, which is available across all our plans (Essential, Pro, Premium, and Vanguard). As well as API security scanning, this license covers web applications (including authenticated areas).

Why is API security testing important?

API security testing is essential for preventing service disruption and lost business, in addition they can be a goldmine for customer data. Without a robust API security solution, they can lead to devastating data breaches. For example, an insecure API resulted in a breach for Australian telco Optus; the details of 11 million customers were accessed by attackers.

How do I best secure APIs?

One of the best ways to secure APIs is by using an API scanning tool to check for vulnerabilities. Here are four more API security best practices:

  • Use tokens
  • Use encryption and signatures
  • Use quotas and throttling
  • Use an API gateway

What is an API endpoint?

An API endpoint is the final touchpoint in an API communication system; typically a URL. Protecting these endpoints with an API security solution is essential, because they make the entire API system vulnerable to attack.
