Cloud Storage Security (CSS) vs GLIMPS Malware for SharePoint OneDrive: Side-by-Side Comparison (2026)

Short answer

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. Mid-market and enterprise teams protecting Microsoft 365 collaboration spaces need GLIMPS Malware for SharePoint OneDrive because it's the only tool that combines 25+ detection engines with automatic quarantine directly into SharePoint, catching threats others miss before they spread across your tenant. The 15-minute PowerShell deployment and native Microsoft Graph API integration mean you're live without infrastructure overhead, and real-time SIEM forwarding closes your detection-to-response gap. Skip this if your organization runs primarily on file servers or lacks Microsoft 365 as a core collaboration platform; GLIMPS doesn't broaden beyond SharePoint and OneDrive.
