Varonis' AI data classification

At Varonis, our industry-leading data classification engine is strengthened by powerful AI data classification capabilities. 

Using novel machine learning techniques to analyze sentiment and business context, Varonis can automatically discover, understand, and categorize customers’ unique data.  

Without accurate and complete data classification, it’s impossible to prioritize risk, remediate exposures, or enforce downstream security controls. Gartner reports that over 35% of data security projects fail due to inadequate data discovery and classification. 

Every Varonis customer is different, each with its own proprietary data types and formats. By combining the power of AI classifiers and Varonis’ battle-tested classification, organizations can reap the benefits of multiple techniques for maximum accuracy, performance, and cost. No rigorous tuning, no black boxes.  

Read on to learn more about how our next-gen AI classification works and what sets us apart from first-gen AI classification solutions.  

Building on our market leadership  

Varonis has long been considered the leading data security solution on the market, with nearly two decades of data classification expertise. Our classification engine is recognized in the Forrester Wave™ for Data Security Platforms for its scalability, accuracy, contextual awareness, and incremental scanning functionality.  

Our data classification approach is based on a principle we call the three Cs:  

  • Complete. We perform full scans on huge data stores. No blind spots.  
  • Contextual. We can determine if sensitive data is exposed, misplaced, mislabeled, or under attack.  
  • Current. We know what’s created and changed as it happens, so visibility is updated in real time.  

Other solutions rely on sampling — even where it is illogical to do so. They provide limited or no context into exposure, identity, or data access activity, rendering them unaware of new or changed data without performing time-consuming rescans. 

A CISO who switched to Varonis from another classification technology said, “Our three-year contract expired before our first scan finished. By then, the results were completely obsolete.”  

We pride ourselves on the ability to act on classification results with real-time alerting on sensitive data sharing, misconfigurations, abnormal access, excessive access — anything that puts data in harm’s way or violates policy.  

The ability to classify multi-petabyte environments has been essential for our success. We’ve addressed the gaps left by first-gen AI-based classification tools, making Varonis the ultimate classification solution for all your data, wherever it lives.

AI data classification done right  

In speaking with customers about their experiences with first-gen AI classification, we identified several challenges with other solutions that were rushed to market or are over-reliant on general-purpose LLMs. These conversations translated into functional requirements for our AI.  

Zero training requirements  

First-gen AI models require well-curated training data — often industry- or company-specific — to deliver accurate results and avoid errors from guesswork or hallucinations. Unlike other vendors, customer data is not needed to train our AI models. Varonis’ AI classification is zero-touch, 98% accurate, and works on any format of data—structured, semi-structured and unstructured. 

The power of context 

Unlike first-gen AI classification, Varonis’ AI classification can identify novel data types specific to your organization without pre-training or configuration and handle ambiguity to reduce false positives and enable more granular controls. Our model understands the business purpose of your data just like a human analyst would, giving you the power of context.  

Transparency and flexibility  

Users of first-gen AI classification reported that it was hard to know whether AI models were identifying the required data sets consistently, especially when combined with sampling, as is the practice with many vendors. 

In other cases, when customers were able to verify that the AI was not identifying the required data sets consistently, they had no recourse but to wait for the vendor to assist — the AI models were a “black box.” Varonis AI models are reasonably transparent and adjustable for customers. 

The magic combo of AI and pattern-matching  

AI classification allows Varonis to expand its already vast classification capabilities to provide teams with a full arsenal to choose the right tool for the job.  

AI specializes in determining context and sentiment. However, AI can be less efficient and less accurate than rule-based classification methods when used to identify many data elements our customers are tasked with finding, such as credit card numbers, credentials, account numbers, and other identifiers. 

The real magic is in combining the two. In current testing, adding trainable classifiers to our existing classification policies increased default accuracy from ~95% to better than ~99%, reducing both false negatives and false positives. 

Ready to secure your data?  

The right data classification strategy can help your company prevent breaches, investigate incidents quickly, and ensure you're meeting increasingly stringent regulations. By focusing on coverage, accuracy, and scale, the Varonis Data Security Platform can help you overcome your biggest security risks with virtually no manual effort.  

  • Combine LLM-based and rule-based classification for fast and accurate results  
  • Understand context around sensitive data exposure, permissions, and access activity  
  • Automatically remediate exposures, enforce least privilege, and apply security policies  
  • Automatically label data to enforce downstream DLP and DRM  
  • Continuously monitor sensitive data and respond to abnormal behavior  

If you have any questions, don’t hesitate to contact us and hear from our customers.
