Email Security

Protect Against the Top Attack Vector

Email security protects against phishing, malware, data breaches and business email compromise, safeguarding sensitive information and ensuring business continuity.

What is Email Security?

Email security refers to measures and technologies implemented to protect email systems, users, and data from cyber threats. It aims to prevent unauthorised access to user mailboxes, ensure email communications’ confidentiality and integrity, and defend against attacks such as phishing, malware, spam, and business email compromise.

Email security solutions typically include email encryption, data leak prevention mechanisms, spam filtering and malware scanning to minimise the risks associated with email-based threats.
