Hello Ninjatech,

I turned off my MFA temporarily and was able to register .

Couple of questions regarding this product

1. How often does it scan the users mailbox? Is this an everyday thing that scans the users mailbox

2.  Sophos Email gateway already quarantines email from the gateway if it detects a malicious URL. Why was this created ? Does that mean 

there are emails that has malicious content that gets through? ELI5 please TY

S&D is a after breach feature. 

Time of Click is the same technique and goes along with this feature. Attacks simply register a new domain, use this without malicious content. As a Gateway has a one time chance to scan, those emails will slip. With time of click, we check the URL again, after the user clicks the URL (hence the name). S&D is a addon to this feature. We target the mailbox of this particular user and get rid of this Email post deliver.
