The use of Windows Terminal Services (WTS) is becoming more and more common in the small/medium enterprise sector. This is mainly due to the increasing bandwidth capacity of modern networks and the need for centralized management to reduce the risk of security breaches in the network. Terminal servers reduce the total cost of ownership (TCO) in an organization.

Companies using WTS solutions have a need for antivirus software that is designed for this environment, different from traditional antivirus software for servers and workstations.

Norman has taken this trend seriously and has developed NVCnet for Terminal Servers - a unique approach to the WTS challenges.

The Terminal Server AV scanning challenge

A problem with On-access virus scanning on terminal servers is unpredictable peaks in CPU usage for the scanning. Some files take a lot of CPU power to determine if they are infected or not, and there are also situations when many users copy or save files to the terminal server at the same time, e.g. at start of the workday. These situations can unpredictably slow down the server, interrupting normal workflow on all terminals.

Testing has proved that this is a problem common to all virus scanners, so moving to other antivirus products will not help. One solution has been to invest in additional servers, to spread the heavy load on more CPUs.

Key features of NVCnet for Terminal Services

• Reducing CPU load on the Terminal Server

• Creating a predictable load usage on the server, reducing risk of peaks

• Load balancing and failover solution

• Ensuring scanning resources always being available

• Norman SandBox - a revolutionary way to detect new and unknown malware
