Sguil (pronounced sgweel) is built by network security analysts for network security analysts. Sguil's main component is an intuitive GUI that provides access to realtime events, session data, and raw packet captures.
SQueRT was created to make most of the data from Sguil accessible via a web browser. While most analysts shun the idea of this, it is especially useful for some people (management, techs) that do not require the real-time event handling and analytical aspects (complexity) of the TCL/TK Sguil client. SQueRT is simply meant to provide a quick overview for non-analysts so that they can address certain obvious problem areas; for example policy violations.
