Santa can run in one of two modes, Lockdown or Monitor. To check the current status run the following command:

The default mode. Running Santa in Monitor Mode will stop any binaries matching block rules, but will not stop unknown binaries from running. This is a flexible state, allowing virtually zero user interruption but still gives protection against known blocked binaries. In addition execution events that would have been blocked in Lockdown mode are generated and can be collected and analyzed by a sync server.
Running Santa in Lockdown Mode will stop all blocked binaries and additionally will prevent all unknown binaries from running. This means that if the binary has no rules or scopes that apply, then it will be blocked.
There are two ways to change the running mode: changing the configuration profile and with a sync server configuration.
