One continuous defence

Detect the signal.
Verify the human.
Protect the payment.

Detect

Behavioural AI scans supplier conversations, domains and payment patterns for signals that manual checks miss.

Verify

High-risk actions — a bank-detail change, a new payment request — are verified independently with the supplier before anyone pays.

Protect

Clear guardrails stop high-risk payments and give business owners the evidence they need to act with confidence.

How it works

From request to decision in three clear steps.

TrustWall sits before approval, combining behavioural detection with human identity verification so only trusted requests reach approval.

Connect your inbox

TrustWall links to Gmail or Outlook and reads incoming supplier emails — no changes to how you work.

TrustWall analyses it

AI and rules examine the sender, domain, tone, deepfake patterns, bank changes and payment behaviour.

Trusted by UK businesses

Small businesses feel the difference.

“It literally saved us from a £12,000 loss.”

Everything looked genuine until TrustWall flagged the supplier invoice for review.

“Finally, something built for small businesses, not just banks.”

Simple setup, smart alerts and real-time insights that actually make sense.

“We sleep better knowing TrustWall is running.”

Our team no longer has to manually double-check every supplier email.

Our story

Turning pain into protection.

Built because one convincing request was one too many.

TrustWall began after a close family member lost years of savings to a supplier payment request that looked completely genuine—from the company logo to the trusted tone.

That experience became a mission: give small and medium-sized businesses enterprise-level protection, and stop fraud before honest people have to face the loss.

“Trust isn’t just our name. It’s our promise.”
