Mail Defender - Complete managed email security

Email is now a business critical application for many businesses and when their email performs badly, so do they. Ensuring email performance under ever increasing threats from viruses and spam is a key priority. Email communications have been targeted by viruses and spam sources for a number of years, to the extent that many users struggle to use the medium productively. The aggressive proliferation of phishing mails has only worsened this trend.
MailDefender provides unrivalled email protection from all email borne threats without requiring an investment in hardware or software or incurring an ongoing maintenance overhead.

The Spam Problem

Spam is an unpleasant fact of life for all companies that use email extensively. Leaving end users to struggle with endless unsolicited mails is unproductive and demoralising, but installing a simple filter is no longer enough. Techniques to generate new forms of spam are highly advanced and proliferate rapidly. In addition, phishing emails, which contain no actual malicious software, are typically designed to lure email users into giving their personal data to fake banking web sites or their PC becoming infected simply by browsing a compromised website.
By incorporating a range of detection mechanisms including, Cloudmark spam detection technology, MailDefender delivers industry leading performance. It is able to block spam with an exceptional degree of accuracy: over 98% of spam and phishing attacks with near zero false positives.

Battling the Virus Problem

Running anti-virus software in-house, has a high degree of latency in the level of protection provided. Your AV vendor has to identify a new threat, produce an update and make it available so you can download and apply it. This can take up to 24 hours leaving you vulnerable to so-called ’zero day’ threats . MailDefender uses Cloudmark technology amongst multiple other scanning engines to identify and block new worms and virus strains in near real time. This results in an unparalleled level of protection from mail borne threats.

Cloudmark: real time protection for online business

With MailDefender in your arsenal, you can ensure once more that email is a valuable tool in your organisation.

Anti-Spam

Identifying spam requires a more modular approach. This is because the interpretation of what makes a virus is standard, whereas what is spam to one person may be another’s must have email.
MailDefender utilises the following methods to identify spam email, each of which can be modified or turned on or off by individual users:

Cloudmark

Anti-Virus

MailDefender uses multiple methods to identify virus emails. The first method is Cloudmark which analyses email payloads for suspicious signs that might indicate that an email is carrying a new form of virus. On passing this test, email is then passed across to the Sophos anti-virus engine to be analysed for the presence of known viruses.
The Sophos anti-virus engine checks for the latest updates from Sophos every 5 minutes, meaning that it is always up-to-date. In the same way, the email is then passed to the Clam anti-virus engine and inty heuristic scanner for further analysis.
