Unleash the Power of AI to Find API Vulnerabilities Before Hackers Do

How it works

You write code. We’ll make sure it’s secure.


Learn your API

All APIsec needs to learn your API is a list of endpoints and methods. Or give us an OpenAPI spec, Swagger, Postman collection, etc. Or integrate directly into your API platform.


Create tests

APIsec automatically creates thousands of attack playbooks to test every corner of your API. The playbooks address the entire OWASP API Security Top 10 and more, giving you complete coverage.


Run attacks

APIsec runs playbooks against your APIs to make sure there are no loopholes for hackers. We can run these in test/staging or production.


Find vulnerabilities

The APIsec playbooks are designed to find the trickiest vulnerabilities - business logic flaws, not just standard security issues. We’ll find any loopholes and integrate issues into your ticketing systems.

API Challenges

The challenges of securing APIs


APIs are highly complex applications with myriad functions, all interoperating to deliver business objectives. Testing frameworks must cover the entire surface area of APIs, exercising every possible feature against all API threat types.


API can be made up of dozens or hundreds of separate endpoints, each supporting 3-5 different methods. Then add the myriad API threat vectors. Comprehensive testing can easily require thousands of unique attack playbooks.


APIs can change daily as Developers release new functionality, fix bugs, update logic, and more. Security assessments cannot get in the way and delay product releases. So testing needs to operate at Developer speed.

In 2019 OWASP led the industry with a clear definition of the Top 10 vulnerabilities that APIs faced. It became the lightening rod for development and security leaders to measure their APIs.

  1. 1Injection
  2. 2Broken Authentication
  3. 3Sensitive Data Exposure
  4. 4XML External Entities (XXE)
  5. 5Broken Access Control
  6. 6Security Misconfiguration
  7. 7Cross-Site Scripting (XSS)
  8. 8Insecure Deserialization
  9. 9Using Components with Known Vulnerabilities
  10. 10Insufficient Logging & Monitoring

APIsec brings the mind of a hacker into API development.

APIsec is an innovator in the field of API security, starting with development, staging and production. It’s our experience working with applications that resulted in the genesis of our product.

"Our customers ask us what we are doing to protect their sensitive data on Seismic, and once they see what we have done with APIsec, their confidence in us grows."

VP Info Security

"As we looked towards building our API focused products we were at a cross-road; do we build API security validations ourselves or do we leverage external companies. APIsec impressed us with what they were able to do quickly and the price to value ratio was incredible."
