Secure the Storage Platforms Your Business Relies On
A Product for Storage Trust
MetaDefender Storage Security connects to your existing storage and inspects files in real time, on a schedule, or on demand. Files are sent to MetaDefender Core, where the technologies scan, sanitize, and assess them. Based on the result, MetaDefender Storage Security allows, sanitizes, blocks, or quarantines the file and records the outcome for audit.

Protection for Enterprise Data Storage
Protect files at rest with a secure data storage solution that delivers robust malware and data security for both on-premises and cloud storage, keeping your critical workflows secure.
All-in-One Enterprise Data Protection Platform for Storage Security
- Deliver real-time and continuous threat detection and prevention across on-prem, hybrid, and cloud environments

- Integrate seamlessly with Amazon S3, SharePoint Online, Azure, NetApp, Wasabi, Scality RING… any SMB/NFS/SFTP/FTP or S3 compatible storage

Rapid Deployment within Your Existing Infrastructure
- Deploy into infrastructure you already run, as virtual machines, on Kubernetes, or from a cloud marketplace image
- Guided onboarding takes you from connecting your first storage unit to your first scan results the same day
- Connect to SIEM and existing workflows through the web interface or the REST API

Automated File Privacy Controls for Regulatory Compliance
- Customize policies and workflows to help meet stringent regulatory requirements for PCI DSS, HIPAA, GDPR and more
- Prevent sensitive data loss or leakage by detecting, blocking, quarantining, and controlling data entry, flow, and exit within the organization

Performant & Scalable Architecture with High Availability for Uninterrupted Protection
- Scale horizontally with additional MDSS and MetaDefender Core instances as file volume grows

Deployment Flexibility: Choose the Right Model for Your Infrastructure
Integrate MetaDefender Storage Security with your existing IT infrastructure, whether on-premises, in microservices architectures, or through SaaS. Choose the deployment model that fits your needs for an enterprise data protection platform that adapts to your environment.

On-Premises
Virtual machines on your own infrastructure, including fully air-gapped environments. You run MDSS, MetaDefender Core and the shared services (PostgreSQL, Redis, RabbitMQ). Scales by adding MDSS and Core instances. Suits regulated and classified environments where nothing leaves the network.

Hybrid
Deploy from AWS, Azure or Google Cloud marketplace images and hand the shared services to managed equivalents such as Amazon RDS, ElastiCache and Amazon MQ. Reduces operational overhead while keeping the deployment in your own cloud account. Containerised deployment on Kubernetes (EKS, AKS or GKE) adds automatic scaling that matches capacity to queue depth.

Cloud through MetaDefender Cloud
SaaS, no infrastructure to run, multi-tenant with tenant-level administration. The fastest route to protecting cloud storage such as SharePoint Online or S3 without standing anything up.
Trusted Globally to Defend What's Critical
Support Your Compliance Requirements
with Confidence
MetaDefender Storage Security helps support a wide range of compliance efforts by scanning stored files for malware, sensitive data, and vulnerabilities, providing capabilities that can help address requirements associated with regulations such as HIPAA, GDPR or PCI DSS.

FAQs
MetaDefender Storage Security is an enterprise-grade file security platform that protects data at rest across on-premises, hybrid, and cloud storage environments. It applies multiple security technologies — including Metascan™ Multiscanning, Deep CDR™ Technology, Proactive DLP™, Vulnerability Assessment, and Adaptive Sandbox — to detect, remediate, and prevent threats in stored files.
Yes. MetaDefender Storage Security handles storage connectivity, file discovery, workflow and remediation, and MetaDefender Core performs the analysis. Every MetaDefender Storage Security package includes a MetaDefender Core engine package, so the scanning depth you need is sized and licensed together with the storage coverage. Core can be self-hosted, deployed from a cloud marketplace image, or consumed as MetaDefender Cloud.
It integrates with more than 25 storage platforms, including AWS S3, Microsoft Azure Blob Storage, Google Cloud, Alibaba Cloud, NetApp ONTAP, Dell EMC Isilon, SharePoint Online, OneDrive, Box, Wasabi, MinIO, and any SMB/NFS/SFTP or S3-compatible storage.
Deep CDR™ Technology processes files by removing potentially harmful content — such as embedded scripts and macros — from over 200 file types, then regenerates a clean, fully functional copy. This approach eliminates threats that evade signature-based detection without blocking the file from use.
Yes. MetaDefender Storage Security can help support your compliance efforts by scanning stored files for sensitive data and generating detailed reports that can be used as part of your audit and compliance documentation, relevant to frameworks such as HIPAA, GDPR, and PCI DSS.
MetaDefender Storage Security can be deployed as Virtual Machines for on-premises and hybrid environments, via Kubernetes (supporting EKS, AKS, and GKE), or as an IaaS/SaaS cloud-native solution requiring no dedicated hardware.
