Internet Edge Design: Proxy or Not To Proxy?We are building a new Enterprise Internet Edge for our organization and are debating whether to use a web proxy for Internet traffic or not. Here are some of the requirements we see fitting for proxy solution:
So far we have looked at following vendors which offer both appliances and cloud-based solutions. We like the cloud based solution because it's simple. But, we have concerns about performance during peak Internet hours for our network.
-Bluecoat (Expensive + Too many appliances)
-Websense (Very Expensive but well known and single clustered appliance)
-Zscalar (Cloud based + Cheaper than previous two + No appliance required)
In this post I would like to see what others are doing and thinking for a web proxy solution for their network. Do you think a web proxy is still needed for a network where advanced firewalls on the edge have the capabilities to fight worms and viruses that can make their way into a network on HTTP/HTTPs ports?
Please leave your thoughts in the comment area.
