Zero-hour Virus Outbreak Detection

With global spam rates reaching 87 % and

higher, and massive botnets capable of spewing

millions of messages per hour, e-mail and security

providers are faced with bloated bandwidth

and deteriorating customer satisfaction. ZyXEL’s

Recurrent Pattern Detection (RPD) technology

provided by Commtouch protects against spam

outbreaks in real-time as messages are mass-

distributed over the Internet. The unique content-

agnostic technology detects and blocks spam in

any language. Rather than evaluating the content

of messages, the Commtouch Detection Centre

analyses billions of e-mails in real-time, recognising

and protecting against new spam outbreaks the

moment they emerge. Also integrated ’Zero-hour

Virus Outbreak Protection’, USG blocks or delays

suspect messages hours before commercial Anti-

virus signatures are available.

Highly accurate classication

The new solution oers a highly improved

detection rate in comparison to other anti-spam

solutions. With the sender-based IP reputation

lter both the necessary systems resources and

bandwidth can be reduced, which enhances

the network performance greatly. The improved

detection rate increases the security and in

addition false positives are eliminated.

The query-based solution blocks spam based on

its most fundamental characteristic – it's mass

distribution. This makes it equally eective against

all types of spam – in any location, format, content,

or language. This proven technology is deployed

in more than 130 countries and analyses billions of

messages per week. It supports double-byte spam

detection and its use is widespread among leading

security vendors.

The new license comes as a 1-Yr and a 2 Yr version

and is available for the whole ZyWALL USG range

from January on.
