Antispam

Email is generally considered to be the most beneficial application to organizations that use the Internet. In fact, most would probably argue that email is now the most mission-critical application within their company.

Spam is no longer just a nuisance: It is quickly becoming both a potential legal liability and a major productivity drain for corporate IT departments and corporate users alike. More than 40% of the respondents to IDC’s email retention survey (which recently surveyed 557 North American organizations) indicated that the number of spam emails received during an average day has risen 50–100% compared with the number received 12 months earlier.

Two Schools of Thought - Filtering & Challenge/Response

Filtering

UTM antispam Filtering technology offers a wealth of features to detect, tag, quarantine, and block spam messages and their malicious attachments. UTM platforms and UTM end-point security agents offer integrated antispam functionality as part of their multi-layered protection, backed by UTM antispam services. UTM appliances complement this functionality with additional features that offer an even more effective barrier against the ever-rising volume of spam, providing the maximum levels of protection against sophisticated email attacks, and with UTM appliance's content archiving functions, assistance with regulatory compliance.

Today's UTM filtering technology provides excellent protection against unwanted emails however they are still subject to the issue of "false positives", the blocking of legitimate emails and "unsolicited" email that slides through the net.

Challenge/Response

Challenge/Response gives users the tools to manage who sends them email. It's a permission based spam blocker that customizes itself to the user.

The result is 100% spam-free email, seamlessly integrated to meet the needs of each user and the organization as a whole. Challenge/Response updates itself as people send and receive mail.

Permission-based means Challenge/Response assumes email is spam unless it knows otherwise.

Only approved email gets into your inbox. Challenge/Response can automatically approve email from people you know and trust. It lets you create simple rules to approve email that is important to you. And it lets you automatically query unknown senders to find out who they are and what they want before their email gets into your inbox. Then you get to decide if this is someone you want to hear from. Legitimate senders respond to this query, but spammers never do.
