Anti-Spam
It’s not only a nuisance to your network users. It costs your company
money, diverts vital bandwidth from business critical applications, clogs
your servers and is now mostly sent by criminal organizations intent on
defrauding individuals and businesses.
Anti spam solutions today are often integrated with anti virus and web filtering solutions, under the broader heading of ‘Email Security’. The reason for this is most spam emails invite recipients to click on a link which then takes them to a page infected with a virus, spyware or other form of malware.
Spam has increased to such a level that analysts now report that the amount of junk mail has grown to about 90 billion messages a day, with botnets and virus-infected computers accounting for about 80% of it.
How can you protect your business from spam?
The key to successful email security software is that it must block spam and malware, without blocking legitimate emails. There are some highly sophisticated solutions for controlling spam, and to ensure complete cover, Metadigm offers solutions that protect against email threats whether they are from SMTP, POP3, web-based email, or HTML embedded within an email.
Some products use list- or reputation-based techniques to identify spam, for example by checking sender IP addresses against blacklists of spammers maintained by ISPs and other organizations on DNS-based Blackhole Lists.
Others use Content Analysis technologies like graphics scans and linguistic heuristics to scan the content and attributes (such as size and format) of each incoming email, in order to classify them as spam or safe.
Within these technologies, some succeed in stopping email threats and spam better than others; others – including Aladdin - offer ‘blended threat’ protection taking a best of both worlds approach. Metadigm can advise on the best solution for your particular requirement, both at the gateway and desktop level.
