Semperis has appointed Alex Weinert as its new Chief Product Officer, leveraging his extensive experience in identity security to drive advancements in hybrid identity protection. Weinert previously led Microsoft’s identity defense team, which protected nearly 45 billion sign-ins daily across the company’s large-scale identity platform.
At Semperis, Weinert will oversee product strategy and development, focusing on enhancing security for hybrid IT environments and enabling enterprises to combat sophisticated cyber threats. “Semperis has been advancing a visionary mission to secure hybrid identities since its inception, and it’s an exciting time to be joining the company as they improve the operational resilience of global organisations,” Weinert stated.
Weinert’s background includes serving as Vice President of Identity Security at Microsoft, where he was responsible for the core defense components of the firm’s Zero Trust offerings. This included technologies such as Entra ID Protection, Entra Conditional Access, and multifactor authentication. His experience also spans engineering and product management roles at Microsoft, contributing to various products including Active Directory and identity-focused solutions.
Mickey Bresman, CEO of Semperis, welcomed Weinert, noting, “He is widely recognised as one of the world’s foremost experts in identity security. His deep technical skills and strategic vision will be instrumental as we continue to innovate at the intersection of identity security and cyber resilience.”
Semperis specialises in safeguarding enterprise identity services for organisations operating in hybrid and multi-cloud environments. The company’s technology secures over 100 million identities globally and is designed specifically for hybrid identity environments. It offers various cyber community resources, including the Hybrid Identity Protection Conference and identity security tools like Purple Knight.

Weinert emphasised the importance of identity security, stating, “Today, there is no more critical place to invest for global security than in digital identity. Semperis is positioned beautifully to extend its already impressive suite of offerings to provide identity integrity to organisations worldwide.”
