Kaspersky Sandbox provides various operating modes depending on the added keys.
No license
This is the mode in which Kaspersky Anti Targeted Attack Platform operates from the time the application is installed and the web interface is started until you add a key.
Unlicensed mode has the following limitations:
Commercial license
In this mode, the application updates databases, and receives and processes data from Kaspersky Endpoint Agent.
After expiration of the commercial license key, the application stops updating its databases and does not receive or process data from Kaspersky Endpoint Agent.
To renew full operation of the application, you must replace the key or add a key for commercial license.
