SpamTitan Protects Networks from Unwanted Guests

Installing SpamTitan is certainly not for those unfamiliar with how networks and addressing work. The initial configuration requires stepping through a maze of settings that should only be attempted by experienced network engineers. However, businesses without their own IT staff, or engineers with limited experience with this type of product, can take advantage of SpamTitan's remote support and configuration capability. Simply select the remote support option, and the SpamTitan support team can remotely access the system, fine tuning or troubleshooting your setup. Figure 1 shows the various setup categories.

Like all email filtering solutions I've seen, SpamTitan prices by user. However, the price is more than manageable. The smallest number of licenses available is 100 for $550, or $5.50 per seat. The price falls as the number of licenses increases, as shown in Table 1. The purchase price includes the first year's maintenance. But don't let the low price throw you. There is a lot of functionality packed into this product.

Three anti-spam filters scan email for spam content. See Figure 2. SpamTitan also offers OCR scanning to stop spammers using images instead of text. Messages are scanned for viruses, worms, and other message-borne malware with two anti-malware scanners: Clam AV and Kaspersky AV. SpamTitan is configured out-of-box to auto-update all scanning engine signature files, and for-fee product licenses, like Kaspersky, are included in the per seat cost.

Once SpamTitan is configured, it is easy to use. Day-to-day operations start with a look at the system dashboard, shown in Figure 3. The Scan Summary is a useful tool for justifying email security expenses to management. The System Overview provides performance data so you know when it might be time to add another SpamTitan appliance. Other information, useful for network vulnerability and source IP blocking tasks, includes:

• Top 10 Virus Relays
• Top Viruses
• Top 10 Spam Relays

The dashboard also provides at-a-glance status of the AV scanners. An additional management feature is a series of graphs, supplied out of the box, that depict daily statistics. See Figure 4.

Overall, monitoring system health and identifying email anomalies are easy tasks to perform.

Once any email filtering system is configured and running smoothly, the biggest potential time-waster can be supporting users who believe important email was incorrectly flagged and placed in the message quarantine area. SpamTitan minimizes this effort with easy-to-use reporting, search, and quick-check tools. Figure 5 shows the quarantine search/management utility. Messages can either be delivered, whitelisted, or deleted from this interface. Other quarantine features include:

• Assignment of administrators by domain, providing granular control that allows distributed management
• User or group whitelisting or blacklisting

Messages users claim are valid, but appear questionable, can be checked with SpamTitan's built-in spam test. Sample results are shown in Figure 6. Using these results, email administrators can decide whether a message presents significant risk or whether delivery is warranted.

Help is available for every panel under every tab. And this isn't just a half-hearted attempt so the vendor can claim it exits. Rather, the help provided is clear, limits technical jargon, and is actually helpful. If an administrator gets stuck, there's always the built-in remote support functionality.
