Every service account you create across AWS, Azure, and Google Cloud has its own lifespan, its own permissions, and its own risks. One forgotten credential can open a door you never meant to leave unlocked. This is the reality of multi-cloud service accounts: powerful, necessary, and dangerously easy to lose control of.
Multi-cloud strategies promise flexibility and resilience. But with multiple providers come multiple identity systems. AWS IAM roles differ from Azure service principals, which differ from Google Cloud service accounts. Each platform speaks its own language for authentication, key management, and rotation. Keeping them in sync is not optional—it’s survival.
Unmanaged service accounts sprawl. Some live far beyond the workloads that needed them. Others carry permissions that grew bloated over time. You may think these are dormant—but many have tokens or keys that still work. Attackers hunt for them. Internal teams accidentally misuse them. The more providers you use, the harder it gets to track them all.
The baseline for multi-cloud security is complete visibility: a real-time inventory of every service account across every cloud. This is followed by automated credential rotation, and finally, principle-of-least-privilege enforcement that adapts as systems change. Anything less leaves blind spots.
