Enterprise:

Network masking addresses the business requirement to segment networks as well as information assurance requirement to secure Layer 2 and Layer 3.  This is particularly true for Energy, Finance and Healthcare. Examples applications include isolating a SCADA network from the utility's IT network, protecting privacy information and financial transactions, as well as network segmentation for trade and export compliance.

Small and Medium Business:

Network masking also provides small and medium businesses with an easy due care option to maintain a reasonable security posture without adopting a large configuration management burden.
