Extra rules

We are developing extra rules to protect run harmful content (ex. webshell) on servers. When you enabling additional rules, it giving you a higher level of security. However, extra rules may also increase the possibility of blocking some legitimate traffic due to false alarms (also named false positives or FPs). It is likely that you will need to add some whitelist for certain applications that need to receive complex input patterns.

If in rules causing a problems, report to us that we may development them better suitable!
