Fraud screening on every signup (Veritus)

Veritus risk-scores new signups before an account goes live, using email, phone, country and IP signals to catch throwaway and high-risk registrations automatically.

It protects both you and any customers you go on to host — which is particularly valuable if you resell, because it stops fraudulent accounts before they cost you anything. Like the mail security, it's built into the platform rather than a paid add-on. More at https://veritus.uk
