Limitations

• As a reverse proxy, WebApp Secure is a Layer-7 device, and must be assigned an IP address. Therefore, Layer-2 bridging functionality (hardware fail-safe) capabilities are not available, and WebApp Secure should not be physically in-line with protected application servers; see the high availability section that begins here High Availability Overview for information on how to reduce the risk of downtime.
• WebApp Secure only accepts HTTP and HTTPS 1.0 and 1.1 traffic because it is the only traffic it monitors.
• WebApp Secure is not a network firewall and should not be an edge device. While firewall capabilities exist on the device, they are not available to the user and are there to protect the WebApp Secure device itself.
• WebApp Secure does not support NTLM authentication.
