About Us

MX Guardian is a cloud-based email spam and malware filtering service that works silently in the background to protect your users from phishing attacks, viruses, spam, denial-of-service (DoS) attacks and other email threats. It frees up your mail server so it only has to deal with legitimate messages and provides a backup MX service to prevent messages from bouncing in case your server is temporarily down or unreachable.

MX Guardian is designed for businesses, ISPs, web-hosting companies, or anyone who has a domain that receives email. We’re also compatible with popular cloud platforms such as Microsoft Office 365 and Google G Suite.
