Link Lock provides protection against phishing, business email compromise, and zero day attacks by removing the possibility of a user clicking on a malicious link in an email. Our SpamTitan spam filter does this by rewriting all links in every inbound email. Subsequently, when a link is clicked, SpamTitan can verify if the destination URL is safe or malicious. If the link is potentially malicious, the user is presented with a TitanHQ block page indicating that there is a security risk.
With Link Lock the links always remain rewritten, even if an email is forwarded. Links are checked in real-time once clicked. SpamTitan allows you to exclude URLs from Link Lock by adding them to an allowed URLs list. If you need assistance with Link Lock, or if you would like this feature disabled for your email address, please contact support@estreet.com.
If Link Lock is not able to determine that a link is safe then you will see the warning message displayed below when you attempt to open the link. You can still proceed to the link but you should only do so if feel confident that the link is legitimate and safe.
