As organizations expand their use of cloud storage and collaboration platforms, files are moving through more systems and more users than ever before. Collaboration tools such as Microsoft Teams and SharePoint Online are now central to daily operations and represent important paths where file-based threats can enter the environment.
MetaDefender Storage Security v4.3.0 extends file scanning and sanitization into Microsoft 365 collaboration workflows, simplifies cloud storage onboarding, and improves control, observability, and performance for large-scale deployments.
Protecting Files Shared Through Microsoft Teams
File sharing through collaboration platforms is now a primary business workflow.
With Microsoft Teams scanning, MetaDefender Storage Security v4.3.0 can scan and sanitize file attachments shared in Teams channels and chats. This extends file security controls into everyday collaboration workflows and helps organizations apply consistent file inspection policies across storage repositories and collaboration tools.
Simplifying SharePoint Online Onboarding
Connecting cloud storage securely should not require manual effort or complex configuration.
MetaDefender Storage Security v4.3.0 introduces SharePoint Online auto-discovery, allowing SharePoint Online sites to be automatically discovered and connected without manual setup. This reduces onboarding time and helps ensure that relevant repositories are protected from the start. In addition, SharePoint storage unit configuration has been standardized across cloud and on-prem deployments. Storage units now use Site URL and Document Library URL fields, with existing configurations remaining compatible, and a post-upgrade prompt to update settings.
Built for Cloud Scale and Multi-Tenant Environments
To support service providers and large enterprises, MetaDefender Storage Security v4.3.0 adds multitenancy support to MetaDefender Storage Security Cloud. Multiple tenants can be managed within a single deployment while maintaining tenant-level isolation and security controls.
This release also introduces initial support for OpenTelemetry, enabling MetaDefender Storage Security v4.3.0 to collect and export telemetry data for monitoring and observability using external tools.
Faster and More Targeted Remediation
Large environments require efficient remediation workflows.
With Reprocess Failed Files, administrators can create new scans that include only files that previously failed and apply any workflow. This allows targeted remediation without re-scanning entire repositories.
MetaDefender Storage Security v4.3.0 also adds flexible scan scheduling, allowing scans to be scheduled down to the minute, as well as real-time protection limits in MetaDefender Storage Security Cloud to help manage resource usage in high-volume environments.
Operational Improvements and Reliability Enhancements
MetaDefender Storage Security v4.3.0 includes multiple usability, performance, and reliability improvements designed to streamline day-to-day operations:
- Clearer scan priority configuration with reordered options and tooltips
- Storage unit names displayed directly in scan configuration
- Enhanced sanitization workflow control, including deleting original files only after successful sanitization and separate delete behavior for allowed and blocked files
- Automatic retry for temporary connection failures
- Faster remediation processing for large-scale deployments
- Improved scan report export experience with a loading indicator
- Improved SMTP host field validation with clearer error messaging
The release also includes bug fixes addressing concurrent SMB scans, partition scans, scan report retention behavior, and notification import validation.
