The SKALE Network is suitable for enterprise apps, where data privacy is a concern due to the security that the network offers. More on SKALE security can be found here:
The SKALE Network is permissionless, and blockchain data is publicly accessible. However, the use of this type of environment in enterprise applications means that the enterprise apps put a stronger focus on security and privacy within their entire app and not just the blockchain parts. A good example of an enterprise app that requires both privacy and security is a health care app that is improving the way health care data is shared between systems, all while integrating with layer 2 solutions like SKALE.
