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.
