About the OSTIF Staff

Derek Zimmer – President and CEO

Derek is a privacy activist, hacker and mathematician. He started his first business in 2000, selling hand-designed PCs to gamers, engineers, and businesses. In 2012 Derek helped found VikingVPN, a VPN service focused on speed, security, and privacy in response to the increasing problems with surveillance on the internet by marketing entities. The May 2013 disclosures by Edward Snowden motivated him to work in the privacy and infosec sector full-time, and to focus his work on countermeasures against advanced persistent threats like governments.

He has personally funded the entirety of the startup costs for OSTIF. He truly believes that the only real response to the death march of surveillance is technological in nature, not political. The ultimate goal of the OSTIF is to liberate the citizens of the world from the oppression of information.

In his free time, Derek enjoys nature, relaxing on a nice patio, reading, dining at new restaurants, travel, art, music, movies, theater and all forms of digital entertainment.

Zachary Graves – Vice President – Design

Born and raised in rural southeastern Ohio, Zach grew up on a beef farm. His parents were both teachers which led him on the path to study math education at Ohio University and landed him a profession as a math teacher in Chillicothe, Ohio. Zach taught at the high school level for 6 years before deciding to change his career to something that put him back outside working with his hands. He now works for a local power company in his current hometown of Chillicothe as a lineman. Aside from his diverse career, Zach has independently worked with graphic design and website management, and has always had a passion for drawing both digitally and on traditional mediums.

In his free time, Zach enjoys golfing, working out, and traveling with his wife.

“This organization and the things we fight for is something I am incredibly passionate about. If we don’t stand up for the rights, safety, and security of the people, who will?” – Zach Graves
