enosix Link Proxy

Detailed documentation for enosix Link is available on the enosix Link Product page.

Introduction​

​SAP offers as part of SAP BTP/Cloud Foundry, SAP Cloud Connector that runs inside your firewall and opens a secure tunnel between your SAP ERP system and Cloud Applications. Using the enosix Link appliance deployed to the SAP Cloud Foundry instance on your account (that you completely own, control, and manage), a proxy to connect Salesforce and SAP ERP can be achieve.

Key features​

  1. The firewall for the on-premise network does not need to open an inbound port.
  2. Provides a secure connection with standard HTTPS with 2-way Transport Level (TLS) Encryption.
  3. enosix Link uses SAP Cloud Connector (that comes with SAP Cloud Foundry) and a proxy server running in SAP Cloud to establish a secure end-to-end channel from Salesforce to SAP ERP.
    • This solution is fully supported by SAP.
  4. The enosix Link app can run in any data center supported by SAP Cloud Foundry (from providers including AWS, Azure, GCP, and SAP), so you can put it close to your other applications, if desired.

Clients are welcome to use their own reverse proxy solution, see requirements for using a custom proxy.
