When using any security tool, it is vitally important for it to help you to find a threat quickly. For most tools, there is a learning curve before you can use the tool effectively, as well as a period during which the tool is tuned for the specific environment in which it is installed. In an ideal world, these processes would take a short period of time to complete, and the tool would then be effective in finding security issues on the installed network. In reality, this is an ongoing process, with the user continually learning how to operate the tool more effectively and tuning it to better detect threats.
