What is a whitelist?
The whitelist is used to allow logins from specified IP addresses or IP address ranges only. Depending on your company security policies, you can restrict users such as agents, admins and owners to log on to the Agent Panel only from the company IP address.
A whitelist is a direct opposite of a blacklist, also called a deny list. As opposed to a blacklist address, whitelisting grants access to a site. You can blacklist email addresses, IPs, usernames, etc. When you blacklist someone, they won’t be able to get access to the site.
In LiveAgent, you can setup Whitelisting IP addresses in Configuration>General
Examples of supported values: exact match (e.g. 192.168.1.1), wildcard notation (e.g. *.*.*.*), range (e.g. 1.1.1.1-1.2.1.1), range defined in form of subnet mask (e.g. 192.168.0.0/16).

Watch what is IP whitelisting
LiveAgent does provide the functionality of IP whitelisting and blacklisting. This advanced security feature enables you to allow or restrict access to your LiveAgent account based on a list of IPs or IP ranges you define in the settings. With IP whitelisting, only users with approved IP addresses can access your LiveAgent account, while IP blacklisting prevents access from specific or potentially malicious IP addresses. This added layer of security helps protect your account and customer data from unauthorized users, ensuring a safe and secure environment for your team and customers.

Expert note
A whitelist is a security tool used to allow login access only from specified IP addresses or ranges, reducing the risk of unauthorized access.
