I’m an OpenBSD developer who enjoys hacking on network related features, such as PF, divert(4), libpcap, the Snort port, and various other bits and pieces.
I’m also the co-founder of Calyptix Security where I lead the development of an OpenBSD-based firewall that protects small businesses and non-profits all over the USA and in a growing number of countries around the world.
In a past life, I was in the Ph.D. program at the University of North Carolina of Charlotte where I did research on Internet security, specifically intrusion detection. A list of my publications can be found on the Writings page.
In an even more distant past life, I was an undergrad at Monash University in Melbourne, Australia.
If you wish to contact me, I’m on Twitter or you can email me at lteo()this.domain.
