Leak Prevention
Stop email leaks
from the inside out


A treasure trove of sensitive content

Leak Prevention from Material
Find and Redact
Automatically protect messages with PII, financials, customer data, and other built-in classes of sensitive content. Secure one-offs manually using native labels or folders.
Challenge
Use your SSO or MFA provider or a custom verification mechanism to authenticate access requests.
Unlock
Access messages directly in mailboxes after verification. Unlocking works across all devices and mail apps without any per-user installs.

Grace Periods
Customize when messages will be redacted to secure content while staying out of users’ way.
Tailored Protection
Set classification, redaction, and unlocking settings by data type, user, department, or domain.
Audit Log and Alerts
Monitor, alert, and rate-limit sensitive content access with built-in audit logs and controls.
Designed for simple deployment and full control
Flexible deployment
Implement protections selectively for specific users or teams. Material deploys via APIs without affecting email delivery. No agents, plugins, or end-user onboarding required.
Your data, owned by you
Every deployment of Material is an isolated, private instance that can be managed by Material or exclusively by your team for total control and includes audit logs.
Extends existing investments
Material integrates with identity providers such as Okta, Duo, and OneLogin as well as common SIEMs.
