13. Chris Wysopal
Co-Founder, CTO, Chief Information Security Officer, Veracode
Under Wysopal's direction, Veracode developed a SaaS-based application code security analysis service that helps software developers identify vulnerability and configuration weaknesses in their software that hackers can exploit. The technology attracted the attention of In-Q-Tel, the CIA's venture capital operation, which bought a stake in Veracode in 2008.
