Varonis

Varonis is a deeply specialized, highly regarded platform focused entirely on securing the most critical layer of any organization: its data. While network firewalls and endpoint agents secure the perimeter and the devices, Varonis assumes that the perimeter will eventually be breached and focuses on protecting the sensitive information stored within unstructured data repositories—such as massive file shares, SharePoint environments, Microsoft 365, and cloud storage like AWS S3. It is designed to answer the fundamental questions: Where is my sensitive data? Who has access to it? And who is actually using it? The core engine of Varonis is its Data Security Platform, which begins by automatically discovering and classifying sensitive information (like PII, PHI, PCI, or intellectual property) hidden across vast, chaotic data stores. Once classified, Varonis analyzes the permissions structures to map out exactly who has access to that data. Crucially, it highlights instances of "overexposure"—where sensitive files are accessible to the entire company or have overly broad permissions (e.g., "Everyone" groups). Varonis doesn't just report on this risk; it provides a safe, automated remediation engine that can simulate and execute permission changes to enforce a least-privilege model without breaking business workflows. Beyond access governance, Varonis provides world-class User Behavior Analytics (UBA) specifically focused on data interaction. It continuously monitors every single file touch—opens, reads, writes, deletes, and permission changes. Using advanced machine learning, it builds a baseline of normal behavior for every user and service account. If an employee's account suddenly attempts to download thousands of sensitive files they've never accessed before (a classic sign of insider threat or compromised credentials), or if a ransomware variant attempts to rapidly encrypt files, Varonis instantly triggers high-fidelity alerts and can automatically disable the compromised account to stop the data exfiltration or destruction in its tracks.
