Aiming to stem the tide of viruses at their most common propagation point, antivirus company Kaspersky Labs Ltd. announced its Antivirus for SMTP Gateways product Monday at the Comdex trade show here.
The software, which sits on the SMTP (Simple Mail Transfer Protocol) servers that transfer e-mail from the Internet to local mail servers, filters e-mail messages and attachments using Kasperksy's antivirus engine and related updates. The software's virus data, or definitions, are updated daily, or more than once a day during a serious virus outbreak, said Denis Zenkin, head of corporate communications at Kaspersky. New updates can be downloaded manually, or automatically pushed to systems as they are released, he said.
Putting antivirus software on the SMTP server, rather than the mail server, improves overall e-mail performance and security by filtering the mail before it makes it very far into the corporate network, Zenkin said.
Kaspersky Antivirus for SMTP Gateways runs on the Linux and Windows NT/2000/XP operating systems. The software will add support for Solaris, FreeBSD and OpenBSD early next year, Zenkin said. The software, which will be available worldwide by the end of November, is priced based on the number of mailboxes protected per year, he said. Software for two hundred mailboxes costs roughly US$10 per mailbox each year, he said.
Kaspersky isn't limiting itself to antivirus software in its drive to improve computer security, Zenkin said. Early next year, the company will expand its product line to include both personal and distributed firewalls, as well as content filtering systems, he said.
