Phishing emails remain one of the most widespread and costly cyber threats facing businesses today. According to industry reports, phishing is responsible for the majority of successful cyber attacks, often leading to data breaches, financial loss and reputational damage.
Recognising the common signs of a phishing email is the first step in protecting yourself and your organisation. In this blog, we break down the red flags you should be aware of, and how to safeguard your business against these threats.

What is a phishing email?
A phishing email is a fraudulent message designed to trick the recipient into sharing sensitive information or downloading malicious software. Cyber criminals often impersonate trusted organisations or individuals to lure victims into taking action.
Common signs of a phishing email
1. Suspicious sender address
Phishing emails often come from addresses that look legitimate at first glance but contain subtle differences. For example, swapping out letters or using domains like .net instead of .com. Always check the sender’s email address carefully.
2. Poor spelling and grammar
Legitimate organisations usually proofread their communications. If you notice repeated spelling mistakes, clumsy sentence structure or unusual formatting, it may be a phishing attempt.
3. Urgent or threatening language
Phrases like “your account will be suspended” or “immediate action required” are designed to create panic and pressure you into clicking links without thinking.
4. Unfamiliar or suspicious links
Hover over any link before clicking. If the URL looks unusual, mismatched or shortened to hide its true destination, treat it as a warning sign.
5. Unexpected attachments
Phishing emails often contain attachments such as invoices or documents that, once opened, release malware onto your device. Only open attachments you were expecting from a trusted source.
6. Requests for sensitive information
Legitimate companies will never ask for login credentials, bank details or personal information by email. Treat such requests as an immediate red flag.
How to protect yourself from phishing emails
- Always verify the sender before clicking links or opening attachments.
- Use multi-factor authentication (MFA) where possible.
- Train your staff regularly on recognising phishing threats.
- Keep software and security tools up to date.
- Report suspicious emails to your IT or security team.
