AWS data security risks in 2025: what governance teams should fix

TL;DR: The 2025 telemetry highlights the top 10 recurring AWS data security risks, showing how sensitive data is stored, accessed, and exposed at scale in cloud environments, according to Cyera. The pattern is clear: cloud security teams need tighter identity, access, and data governance, not just better discovery.

By the numbers:

• 72% of organisations have experienced or suspect they have experienced a breach of non-human identities , 46% confirmed, 26% suspected.

Questions worth separating out

Q: How should security teams reduce AWS data exposure without slowing cloud operations?

A: Start by reducing broad access paths to sensitive data, then recertify the remaining permissions against real workload and business use.

Q: Why do AWS environments create so much data security risk?

A: AWS environments combine scale, speed, and many identity types, which makes it easy for permissions to expand faster than governance can track them.

Q: What do security teams get wrong about data discovery in cloud environments?

A: They often assume that finding sensitive data is the same as securing it.

Practitioner guidance

• Map data to every reachable identity path Build an access graph for sensitive AWS stores that includes humans, roles, service accounts, automation, and third-party integrations.
• Tighten broad roles before expanding discovery scope If AWS roles still have wide permissions, reduce entitlement scope first.
• Recertify cloud entitlements against actual data use Review whether AWS permissions still match current workload behaviour, vendor access, and business need.
