Before the release of Personal Quarantine Manager, it was up to IT administrators to decide which messages to send through and which to block.
"The IT people are often not qualified to make that decision," says Joe Fisher, vice president of product management for Tumbleweed.
Users click on a Release button to send a blocked message through. Email Firewall is delivering anti-spam capture rates of 99% with false positives below 0.1%, the company says. The addition of Personal Quarantine Manager enables companies to give their email end users access to the quarantined spam on a "self service" basis, thus reducing administrative costs. No desktop client software is required, and no separate authentication/password access is required.
The William Morris Agency is using the new capability, citing the advantage of letting the email users decide what to do with quarantined email.
Personal Quarantine Manager is being offered within Tumbleweed's Dynamic Anti-Spam Service (DAS) offered to users of Email Firewall. DAS is blocking more than 32 million spam messages per day on behalf of customers. It is an Internet-based subscription service that updates the firewall with new heuristic defenses as they are published, similar to the way antivirus engines work.
The base price for Email Firewall is $20,000 per CPU. The DAS component is priced at an additional $4,000 per CPU.
As anti-spam products and government regulation have combine to make life more difficult for professional spammers, many of them are moving towards "phishing," the theft of personal consumer information such as credit card and Social Security numbers, as a more profitable venture, says Fisher. As a result, Symantec is working with a number of companies to combat the problem, and more will be announced from the effort in coming months.
"Many spammers are finding that the economics are not as good as they were 12 months ago," says Fisher.
