MetaDefender Storage Security
Multi-layered security for your enterprise storage
About MetaDefender Storage Security
MetaDefender Storage Security is OPSWAT's platform for scanning files at rest and on upload across cloud, hybrid, and on-premises storage such as Amazon S3, Azure Blob, NetApp, SharePoint Online, and Box. It runs files through MetaDefender Core technologies, including 30+ antivirus engines, Deep CDR sanitization, Proactive DLP, and an adaptive sandbox, then applies automated remediation like block, move, encrypt, or delete. It is licensed through quote-based packages sized to storage coverage and deploys on VMs, Kubernetes, cloud marketplace images, or as a service via MetaDefender Cloud.
Pros & Cons
Pros
- Multiscanning with 30+ AV engines plus Deep CDR covers threats a single engine misses, including zero-days
- Broad storage coverage across S3, Azure Blob, GCP, NetApp, SharePoint, Box, and generic SMB/NFS/SFTP
- Combines malware scanning, DLP redaction, sandboxing, and vulnerability checks in one workflow
- Flexible deployment, from air-gapped on-prem to Kubernetes autoscaling or SaaS
- Reviewers report straightforward setup for cloud storage such as Azure Blob, backed by solid documentation
Cons
- No public pricing; every deal goes through sales, and the MetaDefender family is considered expensive for smaller organizations
- Self-hosted deployments require running MetaDefender Core plus PostgreSQL, Redis, and RabbitMQ
- Policies need careful tuning to avoid blocking legitimate business files
- Few independent reviews of the storage product specifically; reviewers want more detailed alerts and dashboard customization
Key Features
Metascan Multiscanning
Scans every file with 30+ anti-malware engines at once to raise detection rates over a single AV engine.
Deep CDR
Content disarm and reconstruction for 200+ file formats that strips active content, recurses into nested archives, and regenerates usable files.
Proactive DLP
AI-based classification and redaction of PII, PHI, and PCI data across 125+ file types, including OCR on images.
Adaptive Sandbox
Emulation-based sandboxing that detonates suspicious files, extracts IOCs, and flags zero-day threats.
File-Based Vulnerability Assessment
Checks installers and binaries against a database of known vulnerable software (30K+ associated CVEs) before they spread.
Real-time, scheduled, and on-demand scans
Event-driven scanning of new uploads plus scheduled and ad hoc sweeps of existing data, with identity scanning to skip unchanged files.
25+ storage integrations
Connects to Amazon S3, Azure Blob, Google Cloud, NetApp ONTAP (including FSx), Dell Isilon, SharePoint Online, OneDrive, Box, Wasabi, MinIO, and any SMB, NFS, SFTP, FTP, or S3-compatible storage.
Automated remediation workflows
Policy-driven actions to copy, move, encrypt, block, or delete files, with up to five destinations and file tagging for forensics.

Best For
Securing file uploads to S3 or Azure Blob
Scan and sanitize user-uploaded files the moment they land in a bucket, before downstream apps or users open them.
Cleaning legacy file shares
Run scheduled sweeps across NAS, NetApp, and SMB shares to find dormant malware and sensitive data at rest.
Compliance with PCI DSS, HIPAA, and GDPR
Detect and redact PII, PHI, and payment data in stored documents and keep audit trails of remediation.
Collaboration platform protection
Scan SharePoint Online, OneDrive, and Box content, including historical versions, to stop malicious files from spreading internally.
Critical infrastructure and classified environments
Deploy fully air-gapped with cross-domain transfer support for OT and government networks.
