Secure Email

Our CT Secure Email gateway provides comprehensive protection against the full suite of common email threats.



Email remains the most common form of business communication and therefore represents one of your organisation’s greatest vulnerabilities. In addition, as more and more organisations move to the cloud, there are multiple new avenues for cybercriminals to attack.

We’ve therefore developed an advanced Secure Email gateway that easily integrates into cloud platforms to provide all-inclusive protection for email channels. Our best-in-class gateway contains built-in threat tracking and response. It’s also been verified for accuracy and overall security by testing firms including SE Labs, VB Labs, ICSA and NSS.

We protect against inbound and outbound traffic and work with all common email infrastructure, such as Exchange, Microsoft 365 and Gmail. We’ve also developed customised tactics to protect against URL revalidation, data leaks, identity-based encryption and many other cyber security challenges.

Improve your security posture with an ISO 270001-certified company. We’ve built secure technology solutions for organisations in the business, government, education and not-for-profit sectors. Focus on what you do best while we protect you.
