What firewall do you recommend

[mghq]

I am trying to choose a firewall and want yalls opinion too.

Also i have mod_security installed with default but removed the following code as i saw on this forum it caused a problem. Should i readd this piece of the default config or leave it removed

# Check decodings
SecRule REQUEST_FILENAME|ARGS|ARGS_NAMES|REQUEST_HEADERS|!REQUEST_HEADERS:Referer "@validateUrlEncoding" \
	"chain, deny,log,auditlog,msg:'URL Encoding Abuse Attack Attempt',id:'950107',severity:'4'"
SecRule REQUEST_FILENAME|ARGS|ARGS_NAMES|REQUEST_HEADERS|!REQUEST_HEADERS:Referer "\%(?![0-9a-fA-F]{2}|u[0-9a-fA-F]{4})"
