He has also consulted for a wide variety of companies, providing managed security services and security assessments of various sorts. Stephen has recently joined iON Secured Networks as a Director in order to allow him to better focus on his passion, network security.
Stephen says, "I have had the good fortune to see the IT and security worlds from a variety of perspectives. I have experienced the challenges of security practice on both a very small and very large scale. I very much enjoy technology and enjoy employing my knowledge hands-on. Teaching for SANS enables me to pass my knowledge and experience on to others while benefiting from my student's unique experiences and perspectives."
He currently holds the GSEC, GICSP, GCIH, GCFA, GWAPT, GAWN and GXPN certifications.
