> Theo de Raadt (/ˈθiː.oʊ dɛˈrɔːt/; Dutch: [ˈteː.o dɛˈraːt]; born May 19, 1968) is a software engineer who lives in Calgary, Alberta, Canada. He is the founder and leader of the OpenBSD and OpenSSH projects, and was also a founding member of the NetBSD project.
I'm open to specific examples if you have them of widespread changes in INFOSEC or massive adoption of better tech due to Theo de Raadt.
EDIT: I'm aware of many good apps they've made. To clarify, my comment is addressing this broad claim:
"The 'net is secure in no small part to his efforts and that of the rest of the OpenBSD team."
OpenSSH might get credit due to massive use. Good example. Past that, what else does most of the net on client side (mainly Windows & Mac) or server-side (mainly Win, FreeBSD, and Linux) depend on from OpenBSD developers?
And yes, that wee piece of software that is the secure gateway of choice and has been for a great length of time; among a great many other innovations mentioned in the link in another reply.
