Re: Deployment Options

Thank you for your prompt response.

We currently have HAProxy serving our sites as a reverse proxy which doesn't nativily support modsecurity. 

What would you recommend in this scenario?

Good evening to you, Kyle,

ModSecurity is usually sitting inline on the proxy. But it's perfectly OK to
have the proxy serve several if not hundreds of backends. The problem is much
more a problem of overall throughput (expect ModSec to eat 10% of throughput
for an average internet site, but your mileage may vary greatly) and in 
some cases a RAM problem with rule set duplication in memory.

Generally: ModSec should not have any problem serving your scenario (if you
change it to "the proxy is the WAF")

Cheers,

Christian
