IAM Won’t Stop Data Exfiltration in GCP — This Will

Most cloud security stops at IAM.

That’s the problem.

In 2026, attackers don’t need to break in — they reuse what’s already trusted. A compromised identity, a misused workload, or a bad automation can still move data across your cloud.

And IAM won’t stop it.

That’s where VPC Service Controls, private endpoints, and endpoint restrictions change the model:

not just who can access,
but where data is allowed to go.

In this article, I break down how to actually prevent data exfiltration in Google Cloud — and why most setups still leave the door open.
