Email Security

What is Email Security?

Email security involves implementing measures to safeguard email communication systems from cyber threats and unauthorised access. It encompasses practices such as encryption, authentication, and anti-phishing measures to protect against risks like phishing attacks, malware, and spam. Regular updates are essential to patch vulnerabilities, making email security a crucial aspect of an organisation’s broader cyber security efforts.

What are the Key Elements of Email Security?


Encrypting emails ensures that the content is only accessible to authorised recipients, preventing eavesdropping and unauthorised access.


Implementing strong authentication methods, such as DKIM (DomainKeys Identified Mail) and SPF (Sender Policy Framework), helps verify the legitimacy of the sender, reducing the risk of phishing.

Anti-Phishing Measures

Deploying filters and technologies to identify and block email phishing attempts, which involve fraudulent emails seeking to deceive recipients into revealing sensitive information.

Anti-Malware Protection

Utilising software and tools that scan email attachments and links for malware, preventing the spread of malicious software.

Spam Filtering

Employing spam filters to automatically detect and filter out unwanted and potentially harmful spam emails.

Access Controls

Implementing access controls to restrict unauthorised access to email accounts, reducing the risk of compromised accounts being used for malicious purposes.

Employee Training

Educating users about email security best practices, including recognising phishing attempts, avoiding suspicious links, and using secure passwords, plus password management.

Regular Updates

Ensuring that email systems and security software are regularly updated to patch vulnerabilities and protect against evolving threats to ensure your organisation remains fully protected.
