Why Email Signature Security Matters
Email signatures are used in nearly every professional email you send, making them an easy target for cyber criminals. You might not realise it, but the information in your signature – such as your name, title, and contact details – can be manipulated to create convincing phishing emails. These scams can lead to compromised data, financial loss, and damage to your company’s reputation.
1. Limit the Information You Share
Including too much information in your email signature, like direct phone numbers or your exact location, can make it easier for cyber criminals to impersonate you. Stick to the essentials: name, job title, and company contact information.

2. Be Aware of Phishing and Spoofing
Phishing and spoofing are two of the biggest threats to your email credibility. Cyber criminals can use familiar-looking signatures to trick recipients into revealing sensitive information or clicking malicious links. These scams often mimic the style and formatting of legitimate emails, making them hard to detect.

3. Use Encryption and Digital Signatures
To verify the authenticity of your emails, consider using encryption and digital signatures. Encryption ensures that only the intended recipient can read the email, while digital signatures verify that the email hasn’t been tampered with. This extra layer of protection is critical for businesses that deal with sensitive information.

4. Standardise Signatures Across Your Business
Consistency is key when it comes to email signatures in your business. Having a standardised format across your business makes it easier to spot anomalies and reduces the risk of spoofed signatures. Make sure everyone in your organisation uses the same signature format to maintain uniformity.
If you need help standardising email signatures across your business, we can offer a centrally managed cloud signature service which gives every member of staff the same signature regardless of where they are or what device they are using. You can even set up seasonal signatures
5. Regularly Audit and Update Your Signatures
Outdated information can be exploited by cyber criminals. Regularly reviewing and updating your email signatures ensures that only relevant and secure information is included. Consider scheduling audits to check for outdated links or unnecessary personal details.
