Welcome

Welcome to my website! I created this site as a platform to share my contributions to the information technology and information security communities. You may have arrived here because you have come across one of my freeware applications or perhaps you have seen my commentary somewhere on some security forum. I frequently contribute to security related discussions online both here and overseas, especially around the topics of Digital Forensics and Incident Response (#DFIR), Security Auditing, and around Security Awareness. I hope that you will find the content and resources on the site to be worthwhile and I welcome any comments and discussions.
