He is a cyber security expert who is known for his unique research into vulnerabilities that affect organizations as well as exposing identity theft risks to the average person. In May 2000, Stickley discovered a buffer overflow vulnerability in the Gauntlet Firewall manufactured by Network Associates. This vulnerability allowed an attacker to remotely execute arbitrary code which resulted in complete compromise of the firewall.
Before this discovery, application firewalls had been considered by many security experts to be the most secure solution for protecting networks on the Internet and Network Associates had claimed Gauntlet to be the "Worlds most secure firewall".
In September 2001, Stickley discovered an additional buffer overflow vulnerability in the same Gauntlet product.
