AI-powered Data Loss Prevention (DLP) for Gmail

Automatically detect and secure sensitive data in Gmail while preventing unauthorized data transfers and risky sharing.

The Data Loss Prevention Challenges in Gmail

Gmail handles your organization's most critical communications but creates significant data security risks that legacy solutions fail to address.

Unmonitored sensitive content

Credentials, PII, PHI and financial data flow freely through outbound emails and attachments with security teams blind to which employees are creating the greatest exposure to external domains.

Intelligent, automated policy enforcement.

Employees download sensitive attachments to personal or managed devices and subsequently upload them to unauthorized cloud services or personal accounts with no data lineage to trace these movements.

Partner collaboration risk

Employees lack simple tools to self-encrypt sensitive content when collaborating with external partners, forcing impossible choices between business velocity and compliance when sharing necessary information.

Key Benefits

AI-powered

Pre-trained LLM and Computer Vision models detect sensitive content with 95% precision - even identifying data within complex spreadsheets, presentation decks, and images where conventional DLP tools consistently fail.

Complete Data Lineage

Trace sensitive email attachments from sending through downloading, subsequent sharing, and final destination - maintaining visibility even after data leaves your Gmail environment.

Comprehensive coverage

Monitor outgoing emails inline and all mailbox messages dating back years. Detect every instance of inappropriate sharing regardless of recipient domain or attachment type.

Streamline Security Operations

Instantly block, quarantine, or encrypt emails containing sensitive data based on recipient domain, content sensitivity or by risk. Apply consistent protection without relying on employee judgment.

Human Firewall

Coach employees with monitor-only policies that educate without blocking productivity. Enable self-encryption through an intuitive plugin workflow that gives users flexible controls to disable forwarding, revoke access, and permanently protect attachments when sharing sensitive content.
