Trustifi BEC and Phishing Defense

Forty minutes from a polite email to a wire you cannot recall

Business email compromise carries no malware and no suspicious link. It is one convincing message to the person who pays your invoices. Trustifi's AI reads the intent behind each email and stops it before anyone acts on it.

The incident

How a normal Tuesday becomes a six-figure loss

The timeline on this page is a composite of how business email compromise typically unfolds. Nothing in it would trip a traditional spam filter, because nothing in it is technically malicious.

Every step relies on a busy person doing their job. That is exactly why it works, and why the defense has to understand context rather than just scan attachments.

Illustrative scenario, not a specific customer Hands holding a phone above paperwork on a desk

Monday, 16:10
A lookalike domain goes live
The attacker registers a domain one character away from a real supplier's and studies public details about your accounts team.
Tuesday, 09:14
The email arrives
"Our bank has changed, please use the new account for invoice 4471." Correct invoice number, correct supplier name, a familiar signature.
09:22
It is read between meetings
Nothing looks wrong on a phone screen. The sender name matches the contact card, and the tone is routine.
09:31
Pressure is applied
A follow-up says the payment is overdue and asks for email-only contact. The phone call that would expose the fraud never happens.
09:54
The payment is released
Funds move to an account the attacker controls. By the time the real supplier chases the invoice, the money has left the destination bank.

The stakes

Why the filter you already have waves it through

Most email security still asks one question: is there something dangerous inside this message? Business email compromise answers no. The danger is in the request, the relationship and the timing.

No attachment to sandbox

Plain text passes every malware scan, because there is no malware.

No link to block

The attacker only needs a reply, so there is nothing to rewrite or detonate.

A sender that almost checks out

New lookalike domains often pass basic authentication checks, and a compromised real account passes all of them.

The response

The same Tuesday, with Trustifi in the path

Trustifi's Inbound Shield evaluates who is writing, whether they have written before, how their domain compares to people you trust, and what they are asking for. Here is how the same sequence plays out.

Moment	Without context-aware protection	With Trustifi
09:14	Delivered to the inbox like any supplier email.	The lookalike domain and first-time sender are recognized, and the message is quarantined or delivered with a warning.
09:22	Read on a phone with no cues that anything is off.	A plain-language Smart Banner explains the risk: new sender, imitated supplier, changed payment details.
09:31	The pressure follow-up lands and works.	The follow-up is linked to the first message and treated with the same suspicion.
09:54	Funds are gone.	The payment is verified by phone, the fraud is reported, and nothing leaves the account.

The capability behind it

Three layers aimed at the attacks people fall for

AI inbound scanning

Every message is checked for phishing, business email compromise, impersonation, spoofing, malware and zero-day files, with URLs and attachments inspected before anyone clicks.

Smart Banners people understand

Warnings are written in plain language and explain why a message is risky, so employees learn to spot the pattern instead of ignoring another generic caution label.

Account Takeover Protection

When the attacker is inside a real colleague's mailbox, Trustifi notices that the account no longer behaves like its owner and flags or blocks it.

With your IT provider

your IT provider connects Trustifi to your mail system without an MX record change, tunes the policies to your payment workflows, and runs phishing simulations so your team keeps its instincts sharp.
