To protect data that is received and transmitted via the HTTP and FTP protocols, the Web Threat Protection component applies various groups of settings. Such groups of settings are called web traffic security levels. There are three pre-installed web traffic security levels: High, Recommended, and Low. The Recommended web traffic security level is considered the optimal setting, and is recommended by Kaspersky. You can select one of the pre-installed security levels for web traffic that is received or transmitted via the HTTP and FTP protocols, or configure a custom web traffic security level. If you change the web traffic security level settings, you can always revert to the recommended web traffic security level settings.
To change the web traffic security level:
When you have configured a custom web traffic security level, the name of the security level in the Security level section changes to Custom.
