• The new features Secure Links and QR Code Analyzer are available for Advanced Threat Protection. Secure Links replaces URL Rewriting. If a user opens a link in an email, Secure Links analyzes the link and either redirects the user to the web page or blocks it. The QR Code Analyzer scans the target link of QR codes that are included in images attached to an email. If the link leads to a malicious web page, the email is blocked and not delivered to the recipient.
