Kerio Control includes protocol inspectors that monitor all traffic on application protocols, such as HTTP, SMTP, SIP, and FTP. Inspectors filter the communication or adapt the firewall's behavior according to the protocol type.
HTTP protocol inspector monitors traffic between browsers and web-servers. The protocol inspector blocks connections to particular pages or downloads of particular types of content.
Protocol inspectors apply to specific protocols and services. All available protocol inspectors are used in definitions of corresponding services.

Note: Each inspector should be used for the appropriate service only. The functionality of the service might be affected by using an inappropriate inspector.
