Executive Leadership

Founder and CEO

Paramount Defenses is led by Sanjay Tandon, formerly, Program Manager for Active Directory Security at Microsoft.

From the United States Government to the Fortune 1000, at the foundation of cyber security and privileged access at 85% of all organizations worldwide lies Microsoft Active Directory (AD).

Tandon was Program Manager for Active Directory Security on Microsoft's Windows Server Development Team in the early 2000s, and as Microsoft's authoritative subject matter expert, he was responsible for all security aspects of AD.

In 2004, Tandon also proposed, conducted and delivered a risk-assessment of Microsoft's own global AD deployment, the very foundation of Microsoft's security, to the highest offices at Microsoft, materially enhancing Microsoft's security.

At Microsoft, Tandon helped improve the cyber security posture of thousands of Microsoft's customers worldwide. In 2005, he left Microsoft to pursue his passion for cyber security, and founded Paramount Defenses in 2006.
