Stop Sensitive Data Before It Reaches AI
Healthcare employees are increasingly using ChatGPT, Claude, Copilot, Gemini, and other AI tools to improve productivity. Unfortunately, these tools can also become a pathway for Protected Health Information (PHI), Personally Identifiable Information (PII), and other sensitive data to leave your organization.
Praevenio intercepts prompts before they reach external AI systems, evaluates content against healthcare-specific governance policies, and blocks risky submissions in real time.
The Challenge
A healthcare employee attempts to submit patient information to ChatGPT:
Without governance controls, this information would be transmitted directly to an external AI platform.
For healthcare organizations, this creates significant risks:
Four Steps to Real-Time Protection
From detection to investigation — a complete governance workflow for every AI interaction.
Detect Sensitive Data
Praevenio's Browser AI extension continuously monitors prompts, file uploads, screenshots, images, and audio content before they are sent to AI applications. By detecting sensitive information and enforcing over 10+ custom built healthcare policies in real time, Praevenio prevents unauthorized disclosures while providing complete visibility into workforce AI usage.
Block the Prompt
Rather than allowing sensitive data to leave the organization, Praevenio immediately intercepts and blocks the request before it reaches the AI platform. Users are presented with a clear explanation of what was detected, why it may be sensitive, and how to remediate the issue.
Rather than relying solely on restrictive policy enforcement, Praevenio empowers users to make safer decisions. Employees can cancel the submission, copy and revise the content to remove sensitive information, or submit a false-positive request for review. This creates a continuous education and awareness loop that helps organizations strengthen AI governance while coaching users toward responsible AI usage.
The result is more than just prevention—it is a scalable approach to risk reduction, user enablement, and long-term behavioral change.
Generate a Security Event
Blocking the prompt is only the beginning. Praevenio provides security and compliance teams with the visibility needed to understand who attempted to share sensitive data, what was detected, which policies were triggered, and why the decision was made. Every event becomes a searchable, auditable record that can be investigated, escalated, and correlated with broader user and organizational risk. The result is complete AI governance—from real-time prevention to investigation, reporting, and compliance oversight.
Investigate and Respond
Detection without accountability creates noise. Praevenio enables organizations to elevate high-risk AI events into formal investigations, ensuring that sensitive data exposures, policy violations, and workforce AI misuse are reviewed, documented, and resolved through a structured governance process. Every case becomes a defensible record containing evidence, investigation notes, ownership, remediation actions, and an auditable timeline—providing the oversight needed to manage AI risk with confidence.
What Was Detected
In this scenario, Praevenio identified the following signals:
| Detection | Result |
|---|---|
| Patient Name | Detected |
| Date of Birth | Detected |
| Clinical Diagnosis | Detected |
| Healthcare Context | Detected |
| HIPAA Identifiers | Detected |
| Unauthorized AI Usage Risk | Evaluated |
Key Capabilities Demonstrated
