Securing SharePoint and OneDrive

SharePoint and OneDrive platforms are facing an unprecedented escalation of cyber threats in 2024-2025, with users 7 times more likely to click on malicious links hosted on these legitimate Microsoft domains. Native Microsoft protections detect only 40% of sophisticated malware.

Today, all organizations use Microsoft 365 for collaborative work. But have you considered the risk posed by malicious files transiting through SharePoint and OneDrive? These cloud storage spaces may unknowingly contain dormant threats waiting for a user to activate them.

Why SharePoint and OneDrive Spaces Must Be Better Secured

  • Underestimated attack vectors: Unlike emails, cloud spaces (SharePoint, OneDrive) are overlooked despite automatically synchronizing across all endpoints and integrating with the entire Microsoft 365 ecosystem, making them a major attack surface.
  • Insufficient native protections: Microsoft Defender for Office 365 detects only ~40% of sophisticated malware. It’s ineffective against zero-day threats and polymorphic variants.
  • Rapid propagation: A malicious file deposited in your collaborative spaces can instantly infect all endpoints via automatic synchronization, contaminate cloud backups, and compromise entire projects before detection.
  • Vulnerable external sharing: Sharing links can allow third parties to deposit files without strong authentication, creating supply chain attack risks with difficult source traceability.
  • Volume and diversity of files: SharePoint and OneDrive can host a wide variety of files (Office, PDF, archives, executables, scripts), representing numerous possible attack vectors.
  • Critical business impact: A compromise can result in encryption of all data, disruption of collaborative processes, and significant remediation costs (averaging €4.45M per major incident). This is why solutions like GLIMPS Malware for SharePoint OneDrive, offering multi-layered analysis with proprietary AI, continuous 24/7 monitoring, and automatic quarantine, have become essential for security-conscious organizations.

Real-World Use Cases and How Files Deposited on Your SharePoint and OneDrive Spaces Are Analyzed by GLIMPS Malware

When a user deposits a project document on a team SharePoint site, such as a Word, Excel, or PDF file, the file is automatically detected by our connector via Microsoft Graph API and analyzed in real-time by GLIMPS Malware. Our proprietary Deep Learning instantly identifies zero-day malware and sophisticated variants that Microsoft Defender consistently misses. If a threat is detected, the file is immediately quarantined in a secure SharePoint site, preventing any propagation within your organization.

When an employee synchronizes personal files from their computer to OneDrive for Business or downloads a file from the Internet, GLIMPS Malware continuously monitors new uploads and modifications. Each file undergoes multi-layered analysis with over 25 detection engines. All analyses can be reviewed through the GLIMPS Malware Expert investigation interface, allowing your SOC teams to access IOCs, MITRE ATT&CK TTPs, and complete behavioral analysis.

When an external partner shares a file via a SharePoint link or deposits a document in a shared folder, the risk of compromise increases significantly. GLIMPS Malware for SharePoint OneDrive automatically analyzes every file from external sources, ensuring potentially dangerous content doesn’t affect your information system. This protection is crucial for preventing supply chain attacks and protecting your company’s and customers’ sensitive data.

When your users save email attachments directly to SharePoint or OneDrive, these files are automatically analyzed by GLIMPS Malware. This dual protection complements your Email Security Gateway and ensures no malware can infiltrate your storage spaces, even if the initial attachment bypassed email protections.
