6 Steps To Improve Your Email Security: A Guide for Irish Businesses

Email is an essential communication tool for both businesses and individuals in Ireland, but it’s also a prime target for cybercriminals. With the increasing sophistication of cyberattacks—now often powered by AI—it has never been more critical to strengthen your email security. Research shows that 95% of IT leaders believe cyberattacks are becoming more sophisticated, with over half already encountering AI-driven threats within their organisations. Taking proactive steps can protect your sensitive information, prevent unauthorised access, and maintain communication integrity. Here are six practical ways to boost your email security.

1. Use Strong, Unique Passwords

Your password is the first line of defence for your email accounts. A weak password is like leaving the front door open for cybercriminals. Strengthen your defences with robust, unique passwords.

Create Complex Passwords

A strong password should include:

• Uppercase and lowercase letters
• Numbers
• Special characters

Avoid common words, phrases, or easily guessable information, such as your name or date of birth. The more complex the password, the harder it is for attackers to crack.

Use a Password Manager

A password manager simplifies security by generating and storing unique passwords for all your accounts. You’ll only need to remember one master password while ensuring each account has a strong, unique password.

Avoid Reusing Passwords

Reusing passwords across accounts is a major risk. If one account is compromised, others using the same password become vulnerable. Ensure every email account has a distinct password to minimise risk.

2. Enable Two-Factor Authentication (2FA)

Two-factor authentication adds an extra security layer to your email accounts. Even if someone steals your password, they’ll need a second verification method to access your account.

Choose a 2FA Method

Popular 2FA methods include:

• SMS codes: A one-time code sent to your phone.
• Authenticator apps: Apps generating time-sensitive codes.
• Hardware tokens: Physical devices producing secure codes.

Pick the method that best suits your needs and preferences.

Set Up 2FA for All Accounts

Enable 2FA on all email accounts. Most providers, including Gmail and Outlook, offer this feature, and it only takes a few minutes to set up. This simple step dramatically enhances your security.

3. Be Cautious with Email Attachments and Links

Attachments and links are common tools for cyberattacks, including phishing and malware distribution. A single click on a malicious link can compromise your entire system.

Verify the Sender

Before opening attachments or clicking on links, confirm the sender’s identity. Unexpected emails—even from known contacts—should be verified through another communication channel. For unfamiliar senders, exercise extreme caution.

Scan Attachments

Use reliable antivirus software to scan attachments before opening them. Many email providers offer built-in scanning tools, but additional antivirus software provides extra protection.

Avoid Clicking on Suspicious Links

Hover over links to preview their destination before clicking. If a link looks suspicious or too good to be true, avoid it. Instead, visit the website directly through your browser.

4. Keep Your Email Software Updated

Keeping your email client up to date ensures you’re protected against known vulnerabilities. Software updates often include security patches that safeguard against emerging threats.

Enable Automatic Updates

Set your email client and operating system to update automatically. This ensures critical patches are applied promptly, without requiring manual intervention.

Regularly Check for Updates

Even with automatic updates enabled, it’s good practice to manually check for updates periodically. This keeps your email client running smoothly and securely.

5. Use Encryption for Sensitive Emails

Encryption protects email content by encoding it so only the intended recipient can read it. This extra layer of security is crucial for sensitive information.

Encrypt Emails Containing Sensitive Information

Use encryption when sending confidential information via email. Most email platforms offer built-in encryption options, but third-party tools can provide additional protection with end-to-end encryption.

Educate Recipients

Ensure recipients know how to securely access encrypted content. Provide clear instructions to avoid miscommunication or mishandling of sensitive information.

6. Watch Your Email Activity

Monitoring your email account regularly helps you detect and respond to suspicious behaviour early.

Set Up Activity Alerts

Enable activity alerts for unusual login attempts or changes to account settings. These notifications allow you to respond quickly to potential threats.

Regularly Review Account Activity

Review your login history and connected devices. If you notice unfamiliar activity, take immediate action to secure your account.

Respond Quickly to Suspicious Activity

If anything looks suspicious, change your password immediately, review your security settings, and consider enabling additional protections like 2FA.
