About Trend Micro InterScan Web Security

Trend Micro Interscan Web Security gives you comprehensive protection against the full scope of web threats with anti-malware, advanced threat protection, URL filtering, and real-time web reputation. Flexible deployments models mean you can deploy onsite, in the cloud, or a mixture of both. And you can manage all deployments through a single management console.

Loadbalancer.org’s web filter expertise helps us to guard against filter failure – ensuring uninterrupted service and excellent user experience.

Key benefits of load balancing

Implementing Loadbalancer.org appliances enables multiple Trend Micro InterScan Web Gateways to be deployed in a cluster. This provides the following key benefits:

• High-availability – If a Web Gateway fails, service is not interrupted
• Maintenance – Web Gateways can easily be taken out of the cluster for maintenance
• Performance – For additional performance simply add more Web Gateways to the cluster

How to load balance Trend Micro InterScan Web Gateways

We recommend deploying in Layer 4 DR mode. In this mode, traffic from the client to the Web Gateway passes via the load balancer, return traffic passes directly back to the client which maximizes performance. Direct routing works by changing the destination MAC address of the incoming packet on the fly which is very fast. This mode is transparent by default meaning that the Web Gateway sees the real client IP address and not the IP address of the load balancer. Due to its speed, overall simplicity and effectiveness, Direct Routing (DR) mode with source IP persistence is our recommended method and can be used in both Explicit Proxy Mode & Transparent Routed Proxy Mode.
