By default, what protocol are links protected by Targeted Threat Protection URL Protect rewritten to?

The correct answer is HTTPS, as Targeted Threat Protection URL Protect is designed to enhance security by rewriting URLs to use the HTTPS protocol. This approach ensures that any links included in emails are directed to secure versions of websites, thereby providing a layer of encryption and security for data transmission. When users click on a link that has been rewritten, they are taken to the secure site, which helps protect against potential threats such as phishing and malware.

Implementing the HTTPS protocol not only secures data between the user and the web server through encryption, but also helps validate the identity of the website being visited. This is pivotal in preventing attackers from intercepting or altering the web content. In contrast, protocols like FTP and SSH do not offer the same web browsing security that HTTPS does, while HTTP lacks encryption entirely, making it less secure for sensitive data exchanges. Therefore, rewriting URLs to HTTPS is a strategic move to safeguard users against malicious attacks.
