The Webroot anti-virus solution not only includes multiple best-of-breed signature based engines, but also various zero-hour and heuristic filters to protect against new and unknown viruses.  The signature based engines provide a company with guaranteed protection against 100% of known viruses.  However, as new viruses appear and others quickly replicate into new strands, the time taken by signature based anti-virus vendors to capture, analyze and release definition updates exposes organizations to the threat of virus infection for a period of time.

To meet this challenge, Webroot employs zero-hour and heuristic filters to seek out new and unknown viruses through additional mail scanning with minimal impact to service delivery.

Spam Blocking

With spam levels regularly being measured at between 65 and 90 percent, Webroot has invested heavily in technology to manage the sheer volume of unwanted email being delivered. Careful attention to connection management and integration of multiple best of breed filters has led to blocking the maximum quantities of spam with the lowest possible rate of false positives.

Pornographic Image Scanning

Many organisations recognise the distress that can be suffered by users who innocently open email to find distasteful images attached. Increasingly, employers recognise that they have a duty of care to minimise these incidents and consequently, Webroot provides a filter specifically to address image analysis.

Protection from Distributed Denial of Service (DDoS) Attacks

DDoS attacks on mail servers consist of a concerted attempt by a person or persons to deliberately prevent a company’s mail communications from functioning. Because email traffic is routed through Webroot prior to reaching a customer’s network, Webroot E-mail Security SaaS protects against these types of attacks.

Protection from Directory Harvest Attacks (DHA)

Directory Harvest Attacks are used by spammers in an attempt to locate valid email addresses though guessing at various permutations of common user names and attaching the domain name. Webroot protects organizations from DHA threats and the associated divulgence of email addresses by transparently consuming emails within the service, rather than publicly rejecting invalid emails.
