I have had experience with other courses, but this was by far my favorite! The instructor has an amazing ability of teaching complex topics while keeping it simple enough for someone just starting out as well as seasoned developers alike. He also brings his own personal experiences into every class he teaches which makes learning from him even more interesting than usual. As others mentioned before me, sometimes there are too many slides at once so you can miss some important information or details. But overall great course! This course covers all aspects of security including input validation/sanitizing, output sanitization, buffer overflows (including stack vs heap), cross site scripting attacks, SQL injection etc.
