FireHost the cloud hosting company that gained fame by offering its services to ace-hacker-turned-security-consultant Kevin Mitnick to prove its security model, now has $12 million in new Series D funding. This round, led like the other by the family-owned Stephens Group LLC -- brings total investment to about $34 million.

safeOne priority will be to boost marketing and raise FireHost's profile to make itself more of a familiar name, CEO Chris Drake told me. And, given that FireHost competes with big companies like CenturyLink (s ctl) Savvis, Verizon (s vz) Terremark and AT&T it's a bit of a David against several Goliaths.

Drake makes some big claims for his cloud: "What we offer is a way to protect customers from the Chinese and the Russians as well as themselves -- you should be as concerned with your database administrator as you are with the NSA because if that person goes rogue, you're in trouble."

Mitnick is just one of several high-profile customers which also include Wal-Mart(s wmt) (the Stephens Group helped take the retail giant public), Kaiser Permanente and Casio as well as high-profile sites for Rush Limbaugh, the Clinton Foundation and the magician David Copperfield all of which are magnets for hackers. (David Copperfield, really?).

FireHost is based in Dallas but hosts cloud servers in Phoenix, London and Amsterdam as well.

"Mitnick has been using us since 2009 and there have been more than 1 million block attempts and zero breeches," Drake said. As Derrick Harris reported last year Mitnick, a non-paying customer, is happy with FireHost but still does not trust any valuable or mission-critical data to any cloud.
