Mark CollierChief Technology Officer SecureLogix

As the Chief Technology Officer at SecureLogix, I manage our technology roadmap, work with our strategic customers, perform security research, monitor for new threats, and architect our security solution. I am actively performing voice/VoIP/UC security research, especially in the area of call authentication, robocalls, spoofing, and Telephony Denial of Service (TDoS). In the area of call authentication, I am researching methods and orchestration approaches, to determine if a the calling number for a calls is legitimate, which has value to any organization, especially financial contact centers.

I have also managed our engineering team for most the history of SecureLogix and directed the development of our voice security products.

I have been working in the software industry for over 20 years. Most recently, I have been working in the voice/VoIP/Unified communications (UC) security and network industry. As CTO, I am focused on identifying new voice/VoIP/UC security threats, performing research including educating our customers and partners on these threats and developing commercial solutions. I am also working with the Department of Homeland Security (DHS) on multiple research projects, focused on call authentication, robocalls, spoofing, TDoS, and other security issues in critical environments such as financial services and Next Generation (NG) 9-1-1 centers. This includes research into detecting 9-1-1 specific threats such as SWATting.

I have also developed a number of SIP attack tools as part of this research and to support the books I have written (Hacking Exposed: VoIP – 2006 and Hacking Exposed: UC and VoIP – 2013).
