What changed

Yesterday, a typo gave the scam away. Today, AI writes it.

The email is flawless. It knows your supplier’s name, your CFO’s first name, your company’s tone of voice. And what used to cost a fraudster a full day now costs nothing.

The answer

Where a filter sees nothing, our AI sees the scam.

A flawless email gives a filter nothing to catch: no virus, no known link, no typo. And you can no longer ask an employee to spot what an AI was built to slip past them. You need an AI stronger than the one on the other side.

What a filter does
  • Compares the email against lists of threats already known
  • Judges each message once, on arrival
  • Has no grip on plain, well-written text it has never seen
What SAFE MAIL does
  • Reads the message like a fraud expert: who is writing, what they ask for, whether it adds up
  • Recognises an attack it has never seen, in any language, however well written
  • Removes the email from every mailbox it reached, even after delivery
One secondAn AI built to decide

Not an assistant that chats: a specialised engine that rules in about a second. The fraudulent email is dealt with before its reader has finished it.

One sentenceAn AI that explains itself

“Announces new bank details, from an address one letter away from your supplier’s.” Every alert says why, in plain words. Your people understand, and decide.

10 or 10,000 mailboxesAn AI that scales with you

The same fraudulent email in 12 mailboxes? Removed everywhere, in one click.

An attack rarely targets one person. As soon as our AI spots a fraudulent email, it finds everyone who received it. You remove it from every mailbox in a single click — even from those who already opened it. Change your mind, and you put it back.

Your spam filter cannot do this: once an email is delivered, it can no longer take it back.
