Whitelisting a website is the process of adding it to a "whitelist" of approved websites. This can be done in order to ensure that the website is safe and secure to use. Once a website is whitelisted, it is given access to specialized resources or services that can help to protect it from malicious threats such as viruses, malware, and other malicious software. Whitelisting is generally done by security software that uses a list of websites with verified security information and will only give access to those websites.
