1. Martin Roesch
VP, Chief Architect, Cisco Security Group
Sourcefire, which Roesch founded in 2001, was already attracting lots of attention for its open-source intrusion detection and prevention technology when Cisco announced a deal to acquire the company for a stunning $2.7 billion. The acquisition, completed in early October, provides Cisco with a deeper threat protection portfolio.
Roesch was Sourcefire's CTO and also served as interim CEO between June 2012 and April of this year. But Roesch is best known for his work developing leading-edge network security tools and technologies for businesses and government agencies.
The Sourcefire acquisition brought to Cisco the security technology it needed to compete against Check Point Software Technologies and Palo Alto Networks. But Cisco also gained Roesch and it will be interesting to see what he develops for his new employer.
