How to Protect Your Business from Phishing (2026)

Phishing — fake emails and messages designed to steal logins or money — is the most common threat facing small businesses. The good news: a few practical habits stop the vast majority of attacks.

What Phishing Looks Like

• An urgent message pushing you to act fast (“your account will be closed”).
• A request to log in via a link, or to pay/change bank details.
• A sender address that’s slightly wrong, or a display name that doesn’t match the email.
• Unexpected attachments or login pages.

How to Prevent It

• Turn on multi-factor authentication. Even if a password is stolen, MFA usually blocks access.
• Use email filtering. Business suites filter most phishing before it reaches inboxes.
• Train your team. A 20-minute session on the signs above prevents most clicks.
• Verify money and credential requests. Confirm any payment or bank-detail change by phone using a known number.
• Use a password manager. It won’t auto-fill credentials on a fake look-alike site, which is a useful warning sign.

What to Do If Someone Clicks

1. Change the affected password immediately and sign out other sessions.
2. Confirm MFA is still controlled by your team.
3. Tell your provider/IT contact and check for forwarding rules or new accounts.
4. Watch bank and payment activity closely.
