The Opportunity

Problem

Enterprise teams risk internal data leaks due to the absence of fine-grained access controls in AI tools.

Solution

LeakSentinel deploys lightweight SDKs to your AI apps, scanning prompts for sensitive data and enforcing granular controls. IT teams get instant dashboards with ML-powered risk scoring and auto-blocks. Perfect for securing custom internal AI workflows without proxies.

Target Audience

Enterprise IT security teams and admins deploying AI tools for internal workflows
