Enterprise Gateway uses persistent connections. These connections eliminate the huge overhead of establishing SSL connections, while providing all the benefits of encryption.

With Enterprise Gateway, you can configure your inner firewall to deny all inbound connections, isolating the Internal Server from the DMZ.

Enterprise Gateway requires no changes to the external client.

Enterprise Gateway rules can be defined to filter client requests.

An Integration Server acting as an Enterprise Gateway Server can handle both HTTP and HTTPS requests. Typically, third-party proxy servers can handle only one or the other.
