DLP for GenAI: Prevent Sensitive Data Leaks into AI Tools
Harmonic’s inline controls prevent leaks of source code, M&A data, and PII with 96% greater accuracy than legacy DLP.
The GenAI Data Leakage Challenge
Employees are pasting your most valuable IP into AI tools that may retain or train on that data. Traditional controls cannot meaningfully prevent this. Regex pattern matching is too noisy to enforce at scale and only catches predictable formats, not the unstructured sensitive data that employees share in natural language.

Harmonic Security: Context-Aware GenAI DLP
Move beyond pattern matching and use Small Language Models (SLMs) to understand the intent and context behind every prompt.
Harmonic Security acts as an intelligent layer between your employees and the AI tools they love. Our inline SLMs sit on the endpoint to analyze and redact sensitive data in real-time, ensuring you can embrace GenAI safely.
96% More Accurate Than Regex
Stop wasting time chasing false positives. Our specialized Small Language Models interpret the nuance of natural language, allowing them to separate routine queries from prompts that contain sensitive materials such as Sales Pipeline data, M&A documents, or proprietary source code. They deliver far higher precision than traditional regex methods, which struggle with unstructured data. All analysis completes in under 200 milliseconds, keeping the user experience seamless.
Prevent Model Training
Automatically categorize AI tools based on their Terms of Service. Instantly detect if a tool explicitly trains on your data or hosts it in insecure regions (e.g., China).
Granular controls let you allow the use of an AI tool for general tasks, but block the submission of PII or IP to preventing that data from becoming part of the public model's training set.
Secure Data in Personal Accounts
Employees using free, personal versions of ChatGPT or Claude pose a massive flight risk.
Harmonic allows you to enforce the use of Enterprise accounts where data is ring-fenced, or restrict the upload of corporate context into personal accounts that employees take with them when they quit.
FAQs
Quick answers about Harmonic Security
Harmonic does not rely on a fixed list or single category of AI tools. It finds AI wherever it appears and evaluates the actual data being shared, delivering controls that Netskope and Zscaler cannot match.
Harmonic uses purpose built small language models that understand user intent and sensitive data in milliseconds. This low latency analysis lets you enforce inline controls without slowing work down, rather than staying stuck in passive monitor mode.
Harmonic can be installed with a range of MDM tools, such as Kandji, Intune, or Jamf. Read more here https://docs.harmonicsecurity.app/browser-extension
