Your sensitive files left email years ago. Your security should follow them.

One policy set, four places work happens
Email, chat, personal file storage and team sites share one set of rules for what is sensitive and who may see it.
Sensitive data types recognized out of the box, per Trustifi.

Threats in shared files
Malicious files and links dropped into chats and folders are scanned, not just email attachments.
Regulated and confidential data
Financial, identity, health and personal information is recognized in documents and messages, then blocked, flagged or restricted by policy.
Find the files that are already overshared
A short review with your provider shows where sensitive data sits in Teams, OneDrive and SharePoint today.
Email security stops at the inbox. Your data does not.
Most businesses secured email years ago, then moved day-to-day collaboration into Teams channels, OneDrive links and SharePoint sites. The contracts, client lists and payroll exports went with it, and the email policies did not.
The result is two standards: strict rules for an email attachment, and almost none for the same file shared as a link to anyone.
Switched on without changing how people collaborate
Collaboration Shield connects to your Microsoft 365 tenant and applies the data loss prevention policies you already rely on for email. Nobody installs anything, and Teams, OneDrive and SharePoint work exactly as before.
Connect the tenant
Trustifi links to Microsoft 365 and starts seeing what is shared, where and with whom.
Reuse your policies
The sensitive data rules protecting email now apply to chats, files and sites.
Fix the riskiest first
Overshared files and risky links are prioritized so the biggest exposures close first.
your IT provider runs the cleanup, then keeps it clean
your IT provider connects Collaboration Shield to your tenant, reviews the first sharing report with you, agrees which exposures to close first, and watches for new ones as your teams keep working. You get one provider accountable for email and collaboration security together.
Protect the files your team shares, not just the ones it emails
Data loss prevention and threat scanning for Teams, OneDrive and SharePoint, from the platform already guarding your inbox.
