Trend Micro's InterScan Web Security Appliance (IWSA) is a real-time, security-rich tool for protecting organisations from web threats. IWSA's new web reputation feature blocks users' access to suspicious domains while performing website reputation scoring without the need of uploading updates. The device blocks both old and emerging FTP and HTTP protocols threats, as well as non-HTTP protocols such as IM communications.

This appliance is capable of stopping all outbound connections to known spyware and phishing websites. The IWAS integrates seamlessly with Trend Micro's Control Manager for even greater coordination, deployment and configuration by fitting into existing infrastructure such as LDAP, ICAPand WCCP.

In the ease of use category, not much has changed since we last saw this appliance. The setup and management are simple and intuitive from start to finish. There is no setup wizard for this device, but that does not hinder the process. Once network IP information is entered via the LCD screen, further configuration is done through the well-organised web interface. The default policy is fairly solid and we had no trouble adjusting policies as needed.

With LDAP proxy integration and specialised IM scanning via the Intellitunnel, this product goes above a standard anti-malware gateway. It also has an optional clean-up program that will quarantine and clean an infected machine before the user is allowed on the network.

Trend Micro provides an easy-to-understand step-by-step administration guide that leaves nothing to chance from a deployment standpoint. The quick-start guide is also excellent. The documentation makes good use of diagrams and screenshots and the table of contents is hot-linked.

Trend Micro offers a premium support program and various other options. The website has a large support area complete with documentation, downloads, technical notes and threat information.

At a price of £10,675 for 2,500 users, this product provides solid protection, even to some larger environments, without a high purchase cost or high administration overhead.
