How to Protect Your Business Against Phishing

Most cyberattacks do not begin with a sophisticated hack — they begin with a convincing email. Phishing tricks an employee into revealing credentials, clicking a malicious link, or approving a payment, and it is the single most common entry point for business cyberattacks. Defending against it is part technology and part people.

What phishing looks like now

Modern phishing is far beyond the obvious scam email. It impersonates colleagues, suppliers, and executives; it creates urgency ("approve this payment now"); and it increasingly uses well-crafted, personalised messages. Anyone can be fooled by a good one — which is why defense cannot rely on people alone.

The technical defenses

• Email filtering — catch the majority of phishing before it reaches inboxes.
• Multi-factor authentication — so a stolen password from a phish is not enough to get in (MFA).
• Endpoint protection — block malicious links and attachments that get through (endpoint security).
• Least-privilege access — limit what a compromised account can reach.

The human defense

Technology stops most phishing; awareness stops much of the rest. Regular, practical training — and simulated phishing tests — turn staff from the most common vulnerability into an active line of defense. The goal is not to shame people who click, but to build instinctive caution.

What to do when someone clicks

Have a simple, blame-free process: report it immediately, change affected credentials, and let IT investigate. Speed matters far more than blame — the faster a suspected phish is reported, the smaller the damage.
