There needs to be a way to verify the status of Host Integrity via the registry.
For SEP clients older than 14.3 RU5 the registry value: "HIEngineResult" can be used to determine the current status of Host Integrity.
Starting from SEP version 14.3 RU5 the same registry value can be checked in HKEY_LOCAL_MACHINE\Software\Symantec\Symantec Endpoint Protection\SMC, even though the system is 64 bit.
