What to look for

Signs the mailbox or payment request needs checking

Unexpected account activity or unexplained changes should be investigated. These signs can help identify what to review.

  • A client or supplier receives new payment instructions that nobody inside the organization can find.
  • Replies disappear, messages move folders, or forwarding and delegation change without explanation.
  • A user sees unfamiliar sign-ins or repeated prompts to approve a login.
  • Staff or clients receive messages from a lookalike domain or a misleading display name.
  • One person can approve new banking details using email alone.

What we do

How we reduce payment fraud risk

Stronger sign-in and mailbox monitoring

We use phishing-resistant MFA where the risk is highest, tighten account recovery, and watch for unusual sign-ins, hidden rules, forwarding, delegation, and connected applications.

Email and domain protection

We investigate suspicious email and review SPF, DKIM, and DMARC. Configuration and ongoing DMARC management are included when they are part of the agreed scope.

A second check before money moves

Changes to banking or payment details are confirmed through a known phone number or another trusted channel, with a clear approval path. The email thread is never the only proof.

Response to suspected account compromise

If an account appears compromised, we can revoke sessions, secure access, remove unauthorized rules and application access, and preserve the mailbox activity needed to understand what happened.

Fit

Is this the right place to start?

A good fit for organizations that

  • Send invoices, receive payment instructions, or handle client funds by email.
  • Use Microsoft 365 or Google Workspace for sensitive client correspondence.
  • Need account protection and a clear payment-verification procedure.

Important limits

  • No email or identity safeguard can promise to block every fraudulent message.
  • Your organization remains responsible for payment authority and for deciding who can approve a change.
  • If a payment may be in progress or a mailbox may be compromised now, treat it as an incident. Do not wait for a routine review.

FAQ

Questions owners and partners usually ask

What the service covers and who is responsible.

Is business email compromise just another name for phishing?

Phishing is often how the attacker gets in. Business email compromise is the fraud that follows, using a real mailbox or convincing impersonation to request money, information, or access.

Will MFA stop it?

MFA greatly reduces the risk, but weaker login methods can still be bypassed and stolen sessions may remain active. Stronger sign-in rules, account monitoring, and payment verification still matter.

Will DMARC protect a mailbox that has already been taken over?

No. DMARC helps other mail systems reject messages that falsely use your domain. It cannot stop an attacker who is sending from a real, compromised mailbox.

What happens if you detect suspicious mailbox activity?

With the organization’s authorization, we investigate, revoke sessions, secure the account, remove malicious rules or applications, preserve the useful records, and coordinate the next steps with your team.
