I’m trying to find about deployment architectures for ASM but I don’t find anything. I’m comparing with other solutions like securesphere, fortiweb, etc and I guess some operation modes (bridge, transparent inspection, reverse proxy, offline) and if it’s posible to support fail open. But with BIG-IP ASM I don’t find this kind of things.
The doubt is… ¿Can F5 ASM works in a Transparent Proxy mode? I know it works as a Reverse Proxy with LTM but, can it runs in a Transparent Proxy mode? And in a Offline (sniffer) mode?
In the datasheets, knowledge base, etc I don’t find anything about it.
I would recommend talking directly to F5 sales, but to my knowledge the ASM cannot run in a sniffer mode, and does not offer a fail open option. It is an active participant in the conversation, so the options you are asking about really aren’t applicable. The options you are describing are more in-line with an IDS/IPS type solution. The ASM is more like an L7 firewall. Imagine running your primary firewall as fail open or on a sniffer port, the same applies here, it just doesn’t work like that.
