Secure Email Filtering


MailGuard proactively secures and protects networks from email-borne threats, assisting you to meet security and compliance objectives


The Business Challenge


IT teams are waging a significant security battle on two fronts: stopping attacks via the web and through email. With spam constituting approximately 95% of corporate email, trying to manage the day-to-day volume in–house is a thankless task.


The drawbacks to owning and managing in–house email security infrastructure are now well recognised. On–site email security software and appliances can constitute a single point of failure. And with a multiplicity of new variants of spam and virus bombarding corporate networks, internal IT resources may be diverted from strategic projects in an attempt to manage the huge volume of internet threats.


MailGuard is the most effective solution to protect your email gateway. It provides an end–to–end hosted security delivering consistent protection against new and evolving spam and virus methods, whilst protecting against data leakage and breaches of


Multi–Layered Security ‘in the Cloud’


MailGuard proactively stops harmful viruses and spam from entering your network. Sitting outside the flow of network traffic, it filters all inbound and outbound email through multilayered protection systems located across our global data centres. Supported by comprehensive email usage reports, MailGuard protects against the unauthorised distribution of confidential or commercially sensitive information by providing a 360 degree view of your inbound and outbound email traffic. MailGuard’s fully managed service delivers peace of mind. Our dedicated team of security specialists and our systems are working 24 x 7 to stop email threats before they enter your network.
