How to Protect Business Email from Phishing

Phishing messages try to trick employees into clicking links, opening attachments, sharing passwords, or approving fake payments.

Why this matters

Small businesses can be especially vulnerable because employees often move quickly and may not have a formal reporting process.

A practical phishing process combines employee awareness with account protection and mailbox reviews.

Common signs of the problem

Small businesses usually notice the issue through daily confusion, delays, repeated support requests, or security gaps.

• Employees are unsure how to report suspicious email.
• Fake invoices or payment requests reach staff.
• Multi-factor authentication is not required for key accounts.
• Suspicious messages are deleted without review.
• There is no follow-up after a phishing attempt.

What to review first

Start with the items below. The goal is to create a clear, practical process that can be repeated.

1. Create a phishing reporting process.
2. Train employees on common phishing signs.
3. Enable multi-factor authentication.
4. Review mailbox forwarding rules.
5. Review account sign-in activity when needed.
6. Document phishing incidents.
7. Update procedures after suspicious messages.
