This is an overview of new security features in Office 365. These features were put into place from November 2021 to January 2022.
Safe Links is a feature that helps protect you from malicious links in email and other Office 365 applications. Safe Links will “re-write” links so that when you try to visit them, they are checked against known lists of bad links. This process will be invisible to you unless a malicious link is detected; in this case you will see one of the warning pages shown here: https://docs.microsoft.com/en-us/microsoft-365/security/office-365-security/safe-links?view=o365-worldwide#warning-pages-from-safe-links This link also includes more detailed specifications about Safe Links, if you are interested.

Safe Attachments is an additional layer of protection for email attachments in addition to the existing malware scanning that already takes place. This feature is mostly to help IT identify and respond more quickly to threats. You shouldn’t notice any difference on your end with this feature enabled.
