input: [Tool] Zeus Extensible Traffic Manager (ZXTM) [By] Zeus Technology Ltd. [Description] 
output: I came across this product recently. Zeus Extensible Traffic Manager (ZXTM) is an interesting product. It looks like a network appliance that is paced between the internet and the servers hosting the Oracle database. ZXTM filters all network traffic destined for the Oracle database or application servers. Any hostile traffic is filtered out and not allowed to pass so thwarting hack attempts against the database. The link to the product includes a simple diagram of how the product works. ZXTM can be deployed on a fault tolerant cluster that acts as an application level firewall. It is also able to load balance the network traffic and filter dangerous network traffic at the same time. ZXTM also supports multiple protocols and can also act as a back end monitor checking that all services are running. A free 30 day trial is available.
