Cloud Storage Security (CSS) vs Solvo: Side-by-Side Comparison (2026)

Cloud Storage Security (CSS)

Mid-market and enterprise teams storing sensitive data across AWS S3 and related services need Cloud Storage Security because its malware scanning actually runs inside your VPC, eliminating the risk of exfiltrating data to third-party scanning infrastructure. Fifteen-minute CloudFormation deployment and native integration with GuardDuty, Security Hub, and EventBridge mean you're detecting threats in your storage layer without rebuilding your monitoring stack. Skip this if you need a multi-cloud solution; CSS is AWS-native only, which is exactly why it works so well for shops committed to that ecosystem.

Solvo

Mid-market and enterprise teams drowning in AWS IAM complexity will get immediate value from Solvo's Policy Manager, which generates least-privileged policies from actual runtime behavior instead of guessing at permissions. The tool covers four of six NIST CSF 2.0 core functions, with particular strength in ID.AM and PR.AA where it maps permissions visually and detects over-privileged access automatically. Skip this if your environment is multi-cloud; Solvo is AWS-only and won't help you manage GCP or Azure identity sprawl.
