How Customs works

It reads each email the way a security analyst would — and tells you, in plain English, whether to trust it. No tech knowledge needed.

Connect
One approval connects your Microsoft 365 — then Customs watches the inboxes you choose.
→
Check the sender
Is the email really from who it says? We verify the email's signature matches the claimed brand.
→
Spot impostors
Fake-brand & lookalike senders (lCIoud→iCloud), and vendors emailing from the wrong domain.
→
Inspect the links
We follow shortened/redirect links to the real destination and flag mismatches.
→
Catch invoice fraud
Payment & “our bank details changed” scams, checked against the vendors you actually pay.
→
Plain verdict
Clear / Caution / Malicious + the reasons — so anyone can decide with confidence.
→
Right in your inbox
A warning label, a banner, auto-move, or a daily summary — automatic, your choice.

Works automatically once connected. Catches phishing, fake-brand logins, and the invoice/banking-change scams that cost businesses the most.
