HOBOKEN, N.J., April 24, 2025 /PRNewswire/ -- Semperis, a leader in AI-powered identity security and cyber resilience, today announced that Guido Grillenmeier, Principal Technologist, EMEA, will be speaking at the RSAC 2025 Conference on The Microsoft Cloud Identity Crisis.

What: The Microsoft Cloud Identity Crisis

When: Tuesday, April 29, 2:25pm - 3:10pm PT

Where: RSAC 2025, Moscone West, 3001

Who: Guido Grillenmeier, Principal Technologist, EMEA

Why: For many years, Microsoft has successfully promoted cloud services and identities, leading to widespread adoption of hybrid identity models. However, cybercriminals increasingly target cloud identities, posing significant risks. This talk highlights the potential crisis businesses face when recovering Microsoft cloud identities after an attack and offers strategies to better prepare for such scenarios.

Guido Grillenmeier is the Principal Technologist of Semperis in EMEA. Based in Germany, Grillenmeier has been a Microsoft MVP for Directory Services for 12 years, helping organizations across industries secure their Active Directory environments and supporting their transition to Windows 10/M365 and Azure cloud services. He spent more than 20 years at HP/HPE as Chief Engineer. A frequent presenter at technology conferences and contributor to technical journals, Grillenmeier is the co-author of Microsoft Windows Security Fundamentals.

In addition, Grillenmeier will be hosting a Birds of a Feather session, Critical Role of Identity Security in Business Resilience: Myth or Reality, on Tuesday, April 29, 9:40 am in Moscone West 2012. He will explore how reliant businesses are on well-secured corporate identities and whether they could continue to operate if these identities were compromised. Grillenmeier will explore these questions and discuss strategies to better prepare for such critical situations.
