What to Look For

Signs the mailbox or payment request needs checking

One sign may have an innocent explanation. A pattern is a reason to check before the organization has to make a decision under pressure.

  • 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 make payment fraud harder to pull off

Each change has a clear purpose, a named owner, and a record the organization can use later.

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 configure SPF, DKIM, and DMARC so receiving systems can distinguish the organization’s legitimate mail from messages that only claim to come from its domain.

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.

A response when something looks wrong

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

Fit

Is this the right place to start?

A useful engagement is clear about the problem it solves and the decisions that remain yours.

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 both technical protection and a payment check the team will actually use.

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 flight 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

Straight answers to settle scope, responsibility, and expectations before the work starts.

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.

We strengthen the account, watch for mailbox misuse, protect the domain, and give your team a safer approval process.
