I've decided to make the WASEC ebook free during these trying times

Short post for the day to address an hopefully even shorter-lived situation we’re all in.

I’ve decided to make the WASEC book free, on LeanPub, for the time being. During these uncertain times, folks might find themselves home from their jobs or, even worse, having to deal with the loss of their livelihood.

If you, like many others, are facing uncertain times and would want to spend time learning and educating yourself on the topic of web application security feel free to have one on me.

Update: 7th June 2020

The book is now back on sale for $9.99, as anticipated by my tweet. In line with my original announcement, I want to provide a path for those who cannot afford the book, so feel free to get in touch if unable to pay.


Hi there! I recently wrote an ebook on web application security, currently sold on leanpub, the Amazon Kindle store and gumroad.

It contains 160+ pages of content dedicated to securing web applications and improving your security awareness when building web apps, with chapters ranging from explaining how to secure HTTP cookies with the right flags to understanding why it is important to consider joining a bug bounty program.

Feel free to skim through some of the free chapters published on this blog and, if the content seems interesting enough to you, grab a copy on leanpub, the Amazon Kindle store, gumroad or simply checkout right down below!
