Cloud Security Posture Hardening
CSPM, IAM right-sizing, and detection tuning across AWS, Azure, and GCP.
Key results
- Critical findings -73%
- IAM over-permission -55%
- CIS benchmark compliance 94%
Context
A multi-cloud SaaS company had accumulated cloud security debt across AWS, Azure, and GCP. Open findings across the three accounts numbered in the thousands, many duplicative across environments; IAM roles carried broad permissions accumulated over years.
Challenge
The security team did not have capacity to remediate findings serially across three clouds. A prioritization framework was needed that attacked the highest-blast-radius issues first without treating every finding as equally important.
Approach
Thoughtwave deployed cloud security posture management (CSPM) tooling across all three clouds, ranked findings by exploitability plus blast radius, right-sized IAM roles using the principle of least privilege, and tuned detection rules to reduce alert noise. The 12-week engagement shipped the highest-priority remediations during the engagement itself.
Outcomes
Critical findings dropped 73%; IAM over-permission across the estate dropped 55%; CIS benchmark compliance reached 94% across all three clouds. The security team now runs a sustainable remediation cadence rather than drowning in accumulated debt.
