LeBlanc, who was charged with improving the security of some of the most widely deployed software products at Microsoft Corp., will become Chief Software Architect at Boulder, Colo.-based Webroot Software Inc.
During his six-year stint at Microsoft, LeBlanc served as a senior technologist for Microsofts network security group and wrote two security-themed titles for Microsoft Press.
He was also a founding member of Microsofts Trustworthy Computing Initiative, a group dedicated to advancing and exploring users trust in computers.
LeBlanc also served as a member of the Mitres CVE (Common Vulnerabilities and Exposures) editorial board.
At Webroot, LeBlanc will be responsible for providing architectural oversight for the development and enhancement of the companys Spy Sweeper and Spy Sweeper Enterprise products.
Webroot also announced the hiring of Henry Rodriguez to fill the newly created position of vice president of software development. Rodriguez was most recently chief technology officer at Dynix, a company that sold automation technologies for libraries.
At Webroot, Rodriguez will manage and drive the software development and quality assurance teams for the consumer and enterprise software suites.
The senior-level hires come just three months after Webroot banked $108 million in a first round of venture capital funding.
The round was led by TCV (Technology Crossover Ventures), a VC outfit with a track record of big-name investments. Accel Partners and Mayfield also participated.
