Experience

Venafi-to-BeyondTrust Connector

For some years, I wondered why Venafi only supported CyberArk as a privileged access management (PAM) solution. After meeting with the CEO and other leaders at Venafi, I presented my vision of a plug-in connector for other PAM suites, such as BeyondTrust. From that initial moment, my vision became a reality.
