Enhance Security with Safe Attachments
Activate Safe Attachments in Microsoft 365 to safeguard SharePoint, OneDrive, and Microsoft Teams against malicious files. Protect your digital workspace from unseen threats.

Why?
In the hustle of our daily work, files and documents are constantly shared across platforms like SharePoint, OneDrive, and Microsoft Teams. While this collaboration is key to productivity, it also opens doors to potential cyber threats hidden in these files. That’s where Safe Attachments plays a crucial role.
Safe Attachments acts like a diligent security guard for your files. It meticulously scans and blocks any suspicious files, ensuring they are isolated before they can pose a risk to your network. Imagine sending a file through a high-tech scanner that instantly detects and quarantines anything harmful—this is what Safe Attachments does. It works quietly in the background, causing minimal disruption to your work while significantly enhancing your defense against cyber threats. By setting up Safe Attachments, you’re not only protecting your data but also maintaining the trust and safety of your entire digital workspace.
