Partner with the leader in data security.

Forrester’s report states "Varonis is a top choice for organizations prioritizing deep data visibility, classification capabilities, and automated remediation for data access."

Go beyond native capabilities.

Windows and NAS devices are home to an immense amount of unstructured data, much of which is sensitive. These platforms have several built-in security auditing capabilities, but the massive event flow is often noisy and difficult to understand — not to mention expensive to store and process. With Varonis, you can understand how users share, access, and use data so you can detect the early signs of threats and remediate risk.

Discover and protect sensitive data.

Varonis automatically discovers and classifies sensitive data hidden in Windows file shares and NAS devices and shows you where you’re at risk. Our least privilege automation determines who needs access and who doesn’t and then automatically replaces high-risk groups with tightly managed groups.

Stop attackers and rogue insiders.

Varonis detects suspicious activity – such as accessing an unusual number of records, escalating privileges, or encryption of multiple files – that could put your file shares at risk.

Varonis solves common Windows and NAS data security challenges

Varonis tackles hundreds of use cases, making it the ultimate platform to stop data breaches and ensure compliance.

Sensitive data discovery and loss prevention

  • Varonis continuously finds and classifies sensitive data hidden in your Windows and NAS files shares  
  • Pairs classification results with permissions to reveal where sensitive data is overexposed  
  • Finds and fixes files that have been misclassified by end users or not labeled at all    

Managing entitlements, permissions, and stale accounts

  • Varonis gives you a clear view of effective permissions, including what users can do, and how they got that access  
  • Decipher complex permission structures like nested groups and inheritance 
  • Easily limit access change permissions to a small group of admins, archive and delete stale users to enforce least privilege, or correct org-wide permissions associated with sensitive files 

Gaps in native auditing

  • Varonis provides a comprehensive audit trail to answer key questions that can’t be determined using only the event log, such as when a file is created vs. modified or when someone failed to access a file  
  • Process millions of events per hour and monitor everything you need with minimal server and network overhead  
  • Accelerate cross-platform security investigations for cloud and on-prem environments 

One platform for multi-cloud, SaaS, and on-premises data.

Varonis protects enterprise data where it lives — in the largest and most important data stores and applications across the cloud and behind your firewall.
