Before Edward Snowden smashed its digital doors wide open, the National Security Agency was seen as the mysterious keeper of an arsenal of dark-voodoo hacking weapons. Now we know the truth: NSA employees are almost too good at what they doas are their counterparts at Israels elite military signal intelligence group, Unit 8200. Unlike people at most government agencies, NSAers and Unit 8200 alums include world experts in their craft, in this case hacking and defending networks and devices. With data breaches now a daily news item, a stint at either agency has become rsum gold for entrepreneurs. Some agency folks are leaving more out of a moral duty to restore some balance back to the private sector. In the last year ex-NSA founders have snagged $9 million for bug-bounty firm Synack, $2.5 million for attack-detection firm Area 1 Security and $10.3 million for e-mail encryption play Virtru. I think its a direct correlation to Snowden, says Ted Schlein, a veteran cybersecurity venture investor at Kleiner Perkins Caufield & Byers. The path from spy to startup is also in full swing in Israel, where entrepreneurs envy the earlier success of 8200 alums such as Gil Shwed and Marius Nacht, the billionaire cofounders of Check Point Software, and Nir Zuk, founder of Palo Alto Networks (market value: $6.6 billion). Here are some of the more high-profile defectors and players in the spy-versus-spy game.

1. LEV KADYSHEVITCH, Head Of Research, Biocatch Its algorithms determine the identity of users based on how they interact with apps, exploiting research on human response to certain phenomena, such as the brief disappearance of a mouse cursor. The 8200-alum-packed firm has $14 million in funding.

2. GIORA ENGEL, Cofounder, LightCyber With his Unit 8200 buddy Michael Mumcuoglu he established LightCyber in 2011 to detect breaches using a network appliance that flags strange-looking traffic. It has raised $12 million to date from VCs and Check Points billionaire cofounder Marius Nacht.

3. TED SCHLEIN, Managing Partner, Kleiner Perkins Caufield & Byers Schlein did not belong to either spy agency but he recognizes their potential. Silicon Valleys top cybersecurity financier recently backed two NSAer firms: Synack and Area 1 Security. The portrayal of the NSA doing things that are bad is not making it the hot place to work inside the intelligence community. I think a lot of their creativity is being curtailed, says Schlein. As a VC, I think its wonderful. As a citizen of the U.S., Id make a different argument.

4. LIOR DIV, CEO, CybeReason The Unit 8200 alum moved his startup from Israel to Boston to tap talent and a bigger market. Its software infers the presence of an attack under way and displays the situation in an easy-to-grasp graphical interface. Div raised $4.6 million earlier this year from Charles River Ventures.

5. JAY KAPLAN and 10. MARK KUHR,Cofounders, Synack Kaplan and Mark Kuhr, both 28, spent four years in offensive security at NSAs counterterrorism division, hacking around for weak spots and finding plenty to exploit. They quit early last year and quickly raised $1.5 million to launch Synack, an army of several hundred freelancers who get paid if they find bugs in clients codesexcept this time the bugs get fixed. We dont work for the NSA anymore. We wouldnt leave a vulnerability or anything like that, says Kaplan. But we would turn away Chinas elite hacking force as a customer.

6. ERAN BARAK, CEO and cofounder, Hexadite Barak was a five-year veteran and officer at Unit 8200 before going into business earlier this year. Hexadite plans to bring automated incident response to the masses. It already has four customers in Israel and the U.S. YL Ventures backed Barak and his colleagues with $2.5 million.
