Bri Hatch is Director of IT at ExtraHop Networks, and Chief Hacker at Onsight, Inc.
He's been doing this security and IT thing so long it's obscene. He can craft sendmail.cf configs from scratch and then shun you for running sendmail. His coworkers swapped several letters on his keyboard and he did not notice until they pointed it out to him several weeks later.
Bri has taught security, Unix, and programming classes for corporations through Onsight and as an adjunct instructor Northwestern University. He has been securing and breaking into systems since before he traded in his Apple II+ for his first Unix system. He is also co-maintainer of Stunnel, an Open Source secure SSL wrapper used around the world to encrypt cleartext protocols.
