About Me

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.
