Add-on
Armor Mail
Cloudflare email security that catches invoice fraud, phishing, and spoofed suppliers — set up, tuned, and monitored by Tremhost engineers. Works with Microsoft 365, Google Workspace, or your own mail.
Invoice fraud is how money actually leaves a Zimbabwean business
Armor Mail is Cloudflare’s email security, managed for you. It reads every incoming message for the signs a spam filter misses — a supplier’s address one letter off, a reply inside a real thread asking for new bank details, a link to a fake Microsoft login — and quarantines it. Our team tunes it to your mail flow, handles quarantines, and sends you a monthly report on what it stopped.
How invoice fraud takes money from Zimbabwean businesses:
01 The thread is real
Same people, same subject line, same friendly sign-off. Everything checks out because everything is real except the account number.
02 Procurement pays it
They're doing their job. Nothing looked wrong, because nothing was wrong until the last message.
03 The money is gone
Cross-border, withdrawn within hours, and your bank's recall process is a formality. Recovery is rare.

Questions people actually ask
1. Does this work with Microsoft 365 and Google Workspace?
Yes, both — and with mailboxes hosted here. Deployment is by API for Microsoft and Google, which means no MX record change and no interruption at all.
2. Will we lose legitimate mail?
That's what the two-week monitor period is for. We tune against your actual mail flow before anything is blocked, and we manage the quarantine ourselves so a false positive is our problem, not your staff's.
3. Is it cheaper than Microsoft's own add-on?
Yes. Defender for Office 365 Plan 1 lists at $2 per user a month. Our ten-pack works out at $1.20 a mailbox, and $1.50 standalone — with the tuning and the quarantine handled for you.
4. We already have spam filtering. Isn't this the same thing?
No. Spam filters catch bulk junk. Invoice fraud arrives as a single, well-written, personally addressed message in a real thread — exactly the kind of mail a spam filter is designed to let through.
5. What if someone clicks anyway?
Tell us immediately. We'll help contain it: reset credentials, check for forwarding rules the attacker set, and look at what else in your mail was touched.
6. How many mailboxes do we actually need to protect?
The ones that receive invoices and the ones that can authorise payment, at minimum. In most businesses that's finance, procurement, the directors and reception. Ten covers a typical small office.
