Latest Release of Webroot® E-Mail Security

SaaS Provides Protection Against Bounce Back Messages Generated

by Spammers

BOULDER, Colo.–(EMWNews)–Webroot,

a leading provider of security software for the consumer, enterprise and

SMB markets, today announced the latest release of Webroot®

E-mail Security SaaS which features advanced protection against the

growing threat of e-mail “backscatter.”

A side effect of spam, viruses and worms, backscatter occurs when a

spammer spoofs a legitimate e-mail address to send an unsolicited

message to large distribution lists, causing the e-mail server to flood

an unsuspecting e-mail address owner’s mailbox

with hundreds or thousands of failed delivery messages or bounce backs.

“Ninety percent of over 6 trillion business

e-mails this year will be spam. This volume puts IT resources under an

incredible strain to manage not only the spam but the ensuing

backscatter. Just recently an ISP was driven offline while trying to

absorb 10,000 backscatter messages per second,”

said Mike

Irwin, COO, Webroot. “The impact of

backscatter is especially hard on businesses with fewer IT resources or

appliances that just can’t scale to meet the

processing load. With network security in the cloud, companies of all

sizes can enjoy a scalable enterprise-class security solution that is

easy to manage and provides better protection and value than traditional

appliances and software.”

Failed delivery messages – triggered by an

e-mail sent to an invalid address or a full mailbox –

can be difficult to block and tag as spammed messages, and require

significant time and resources to be cleared from the network. The

latest release of Webroot E-mail Security SaaS employs a technique

called Bounce Address Tag Validation (BATV) to mark every message sent

through its servers with a timestamp and unique cryptographic signature

that cannot be duplicated. If an e-mail enters the network as a failed

delivery message without this signature, customers can then configure

the service to automatically mark the message as spam and block it from

entering the user’s mailbox.

“Companies still struggle to keep up with spam

volume and attack tactics years after spam first became a serious

problem, and many see a continued investment drain for spam management,”

wrote Chenxi Wang, Ph.D., Principal Analyst, Forrester in the June 2008

report Spam Management Best Practices. “To

keep a step ahead of spammers, organizations should adopt a hybrid of

filtering solutions, strengthen this connection to management

technologies, and treat antispam as part of a wider email content

security strategy that includes content protection and compliance.”
