AI-powered Data Loss Prevention (DLP) for Microsoft Teams

Automatically detect and secure secrets and credentials, sensitive PII, PHI, PCI data in Microsoft Teams

The Data Loss Prevention Challenges in Microsoft Teams

Microsoft Teams centralizes workplace collaboration but creates unique security blind spots that alternative solutions like Microsoft Purview cannot address.

Sensitive data everywhere

PII, PHI, PCI and credentials flow freely through conversations, often disguised in screenshots, attachments, snippets, or conversational context that pattern-matching tools miss completely.

Intelligent, automated policy enforcement.

1:1 chats, group chats, private teams, and public teams multiply exponentially, with new data exposure risks introduced daily in channels that security teams cannot monitor effectively.

‍

Failed traditional approaches

Current solutions force impossible tradeoffs between security, accuracy, and productivity with clunky interfaces, constant false positives, and frustrating user experiences that do not eliminate date exposure risks.

Key Benefits
