Profile bio
About Mark Tanui
Professionally, I am about cyber security research and its application in making the Internet safer and more meaningful for everyone.When I consider how I would like to spend my days on this earth, I imagine giving my all to everything I do. Some people call this ‘dying broke’ - having used every moment, every opportunity, and maybe some good fortune to live a life worth dying. It’s more like when I like it, I crown it. It’s about putting my heart into everything I enjoy and finding fulfillment.
