94% of orgs had some sort of breach via M365 last year. Most still think "Microsoft backs up my data" (spoiler-they don't).
M365 attacks are up 300%. One org lost $25.6M to a deepfake call.
Quick wins:
✅ Test your backup
✅ Enable admin MFA
✅ Kill legacy auth

What a blast during my session today! I love talking about reframing cybersecurity through the lens of digital wellness and collective resilience. Nothing better than helping orgs realize that security should enable, rather than prevent, meaningful connections between people and orgs. #CRLVIRTCON

Field Notice: FN - 70620 - Moving Existing HyperFlex ESXi Hosts to vCenter 7.0 Update 1 Can Unexpectedly Power Off and Delete the HyperFlex Controller VMs - Workaround Provided
An interoperability issue between HyperFlex and vCenter 7.0 Update 1 (U1) has been identified that impacts HyperFlex controller virtual machines (VMs) that are managed by vSphere ESX Agent Manager (EAM). At the time of initial publishing of this notice, vCenter and ESXi 7.0 and 7.0 U1 were not supported with HyperFlex, and this notice was issued out of an abundance of caution.HyperFlex Data Platform (HXDP) Software Releases 4.0(2) and 4.5(1) and later now support vCenter Server 7.0 U1c (build 17327517) and later. Refer to the HyperFlex product documentation links in the Background section for full interoperability details.
