Internet Connections

VPN
    VPN (Virtual Private Network) is a network that uses tunneling technique to transmit encrypted data from point to point over the public internet. A VPN provides hard data encryption at the hardware level. This approach requires a VPN switch (VPN gateway) at the customer site and at SAP and SAPRouter software.
SNC
    SNC (Secure network communication) connections are established between two SAPRouters. No additional hardware is required at either end of the connection. The technology of SNC makes the connection over the internet secure, using state-of-the-art encryption.

SAProuter

SAP has been using the software component SAProuter since 1995 to further increase access security to customer systems. SAProuter is only installed on one customer system. It contains information about all connected systems and forwards external requests to these systems, provided the appropriate authorizations exist. It is therefore only necessary for this one system to be accessible from outside. SAProuter also ensures that the customer only needs to know one IP address at SAP to establish a connection.
Internet connection

You can establish remote Internet connections to SAP in two ways:

    Secure network communications (SNC) via SAProuter software to deliver software encryption
    Virtual private networks (VPNs), which provide hardware-level encryption

Both options use three types of security measures to protect your systems and data from unauthorized access: state-of-the-art encryption, user authentication, and access-control technology. The method you select depends upon your existing infrastructure, your requirements, and your preferences.

Network providers which also offer access to the Internet are obligated by SAP to set up VPNs (virtual private networks) to screen outside access to the SAP Service Network. Please contact the providers for more information.
