Our Mission
We wish to provide free, high-quality education and resources on all aspects of API security that are easily accessible across the globe.
After reading an interview with Corey in 2021, Dan stalked Corey and got on a call with him. The rest is history.
APIsec supported Corey in compiling his book on Hacking APIs. We read advanced copies, offered feedback, and helped promote it. Dan wrote the Foreword at Corey's request.
After publishing the book, we decided to create an online course to go with it. Corey recorded the API Penetration Testing course while I built the website. We launched it in August 2022.
APIsec U has exceeded our expectations. We're happy to offer high-quality courses and content for free. The community's response has been overwhelming, and we're grateful for the opportunity to make a positive impact in cybersecurity.
After the remarkable response to Corey's first course, we started hearing from organizations about their need to deliver training to their API developers and product owners. So, we created our second course, API Security Fundamentals. We now offer our courses to deploy in internal learning platforms (LMS). We plan to continue adding more courses on API security, API development, API governance, and much more - and we're partnering with remarkable experts in each of these areas to create these classes.

I highly recommend taking the API Penetration Testing course by Corey J. Ball on APIsec University. I had a blast working on this course. You will have the opportunity to learn and apply the concepts right after with a hands-on lab that you can install and deploy yourself."

David Bombal
I love what you’ve done, if you take the free course, within a month, two months, three months, you can do this. Thank you so much for creating a free course and making this available to people around the world."
