Enhanced Security Features for Microsoft 365 Copilot Chat
Microsoft has recently introduced a series of security enhancements for users of Microsoft 365 Copilot Chat, a move that aims to bolster user safety while navigating through links provided by the assistant. Notably, the integration of SafeLinks from Defender for Office 365 marks a significant upgrade in security protocols.
What is SafeLinks and How Does It Work?
SafeLinks offers time-of-click URL protection, ensuring that every link generated by Copilot is evaluated before the user can access it. When you click on a link, a pop-up notification appears, informing you that Microsoft is assessing the link’s safety. Should the link pose a security risk, a warning will be presented to prevent potential threats.

Accessibility of the SafeLinks Feature
This critical feature is accessible to subscribers of Microsoft Defender for Office 365 Plan 1 or Plan 2 without any additional configuration required within their SafeLinks policy. Moreover, administrators can utilize the Microsoft Defender for Office 365 Security Center to generate reports, allowing them to track potential threats and monitor actions taken against them.
Time-of-Click URL Reputation Checks
Recognizing the importance of user security, Microsoft has further implemented time-of-click URL reputation checks for links in Copilot’s responses. If a link is identified as malicious, users will again receive a pop-up warning them not to proceed with the visit. This proactive approach helps ensure a safer browsing experience for all users.

Improved User Experience
In an effort to enhance the overall user experience, Microsoft 365 Copilot Chat will no longer redact any links from chat responses if they are part of the grounding data used to generate those outputs. This change allows users to dive deeper into topics of interest without unnecessary barriers, fostering a more informative engagement.
Future Updates and Enhancements
Looking ahead, Microsoft plans to extend SafeLinks protections to Copilot App Chats within popular applications like Word, PowerPoint, and Excel. This expansion reflects Microsoft’s commitment to making productivity tools not only efficient but also secure.
