You can customize your account via the Account Preferences.
You can participate in testing new features by enabling the beta test option. This will enable new beta features for you in the user interface and the SenseDeep agent.
In learn mode, SenseDeep accumulates a profile of expected behavior for your site that is used to detect future aberrant behavior that indicates attacks or threats. Learn mode is currently only performing data gathering. Overtime, this profile will be used to detect latent threats and attacks based on patterns of behavior.
If you enable or disable Beta test or Learn mode, you may need to log out and log back in for the change to take effect in the user interface.
