Problems sign-in into office.com after reebot to apply endpoint updates - January 2025

Question

Hello, 
 After reboot the PC to apply the latest Sophos Intercept X updates (Core agent 2024.31.3.0/ Sophos Intercept X 2024.1.2.1.0) is not possible to login into office 365 web page via Office.com. The page loads but hitting the Sign.in button the page get completely blank. 
 Disabling the web-control on the endpoint it works fine. 
 This is happening to all computers with Sophos Endpoint, after rebooting to apply the latest updates. 
 Can anyone help me with this situation? 
 Thank you.

Hello, Rafael Sardinha , 
 We appreciate your reaching out to the Sophos Community Forum. 
 
 This might happen because Sophos scans files and URLs using a combination of real-time analysis, static and dynamic analysis techniques, and threat intelligence from SophosLabs to identify malicious content; when a file or URL is accessed, Sophos checks it against its database to determine if it's a threat and can block access to malicious content based on its findings. Therefore, it might block this site. 
 You can check files and URLs on this link if it's malicious: https://intelix.sophos.com/ 
 I suggest you add the web control exclusion on the central console. As you mentioned, turning off the web control works fine.
