If new devices are released in the market by other vendors which support IPSec Tunneling, an enhancement can be done in smarts to support those devices also.
In case if you wish to add any other device which has the IPSec Tunneling and not supported by Smarts, please raise a re-certification request for the device & mention the need to support the IPSec tunneling.
This will be evaluated by the product management team taken up as a device certification in the future releases of the product.
