SendGuard for Outlook serves as a security enhancement tool specifically tailored for organizations using Microsoft Outlook and Microsoft 365, with the primary goal of improving email safety. It effectively reduces the chances of messages being mistakenly sent to the wrong recipients and helps prevent accidental data leaks by prompting senders to verify their recipient lists and attachments, as well as highlighting external email addresses and issuing alerts before a "Reply All" action occurs. Administrators can set up customizable rules for outgoing emails that can enforce checks for sensitive information and initiate various responses, including blocking, delaying, or prompting the sending of messages; those on premium plans can also take advantage of attachment content scanning. Furthermore, SendGuard offers additional functionalities like message delay and cancellation, branding customization options, and comprehensive activity logging for users. This add-in is designed to work seamlessly with Windows desktop and Microsoft 365 versions, allowing for centralized management and deployment. Importantly, the Microsoft 365 edition is accessible via New Outlook, Outlook on the web, and Outlook for Mac, and it also supports mobile use of Outlook. This solution is particularly advantageous for teams in industries such as professional services, healthcare, finance, and the public sector, where handling sensitive email communications is a routine aspect of their operations. In summary, SendGuard not only bolsters email security within organizations but also enhances overall communication efficiency and practices among teams.
