By whitelisting an IP address or a CIDR range you can instruct Threat-X to not inspect requests from those IPs. The ThreatX portal allows you to easily whitelist an IP Address or a CIDR range.
As first step you will have to log into the ThreatX portal at x.threatx.io and access
Settings > IWAF from the navbar.
Select the Whitelist tab and click on Add Entry in the top right corner.
This will present you with a pop to add the IP address or the CIDR range. Add and click Submit.
If you are whitelisting an entry previously in the blacklist make sure that you remove it from the blacklist.
