Today, over 270 million people use Microsoft Teams, as it is an efficient collaborative platform. With this increase in users, malware and phishing attacks also sneak into the peak. In these hybrid work environments, all we need is strong security for our collaborative platforms, right? Therefore, Microsoft started to equip Teams with several strong security measures, and now in the list, Microsoft introduced a ‘Zero-hour auto purge for Microsoft Teams. ZAP behaves as an extra layer of defense to safeguard Teams users and protect against potential security threats.

Safe links-Microsoft introduced safe links in Microsoft Teams to scan every incoming URL shared in group chats and Teams’ conversations. Once a suspicious URL is detected, it prevents the users from entering the spam website and protects the end users from ransomware attacks.

Report malicious messagesAlso, Microsoft offers users the ability to report messages in Microsoft Teams immediately. When users report a message, the security team gets notified and can review the reported message through Microsoft 365 Defender.

Zero-hour auto purge– Sophisticated cyber-attacks can rapidly propagate across an entire organization, causing widespread damage and compromising sensitive data. In this situation, the speed at which the SecOps unit can respond is somewhat difficult. So, Microsoft now brought zero-hour auto purge to Microsoft Teams. This new security feature will greatly enhance Microsoft Teams’ security and make it even more secure.
