How to Protect Your Business from Email Spoofing and Business Email Compromise

Email is still the number one way cybercriminals target small businesses.

A common method is email spoofing — where a scammer makes an email look like it’s from your boss, supplier, or even your own domain.

This often leads to Business Email Compromise (BEC) — where fraudsters trick staff into transferring money or handing over data.

📬 How spoofing works

  • Attackers send an email that appears to come from a trusted address

  • The “From” name looks genuine, but the underlying sender isn’t

  • Urgent or unusual requests (like “pay this invoice today”) push staff into quick action

🚨 Real-world examples

  • Fake invoice emails appearing to come from suppliers

  • HR asking for staff payslip details

  • Directors “authorising” urgent bank transfers

Many SMEs across the UK have lost thousands this way — often without insurance cover.

✅ How to protect your business

1. Train your staff
Help them spot red flags: urgency, odd email addresses, unusual payment requests.

2. Enable Multi-Factor Authentication (MFA)
Even if credentials are stolen, MFA can block attackers.

3. Use proper domain protections
Set up:

  • SPF (Sender Policy Framework)

  • DKIM (DomainKeys Identified Mail)

  • DMARC (Domain-based Message Authentication, Reporting & Conformance)

These stop criminals sending spoofed emails from your domain.

4. Have a process for financial requests
E.g. “Always confirm by phone before paying invoices over £X.”

👣 Practical first step

Check your domain setup. If SPF/DKIM/DMARC aren’t in place, your email is at risk.

Most SMEs aren’t aware these protections even exist — but they’re free to set up and highly effective.
