You can detect SAPRouter applications using this tool.
SAP router is a standalone program that protects your SAP network against unauthorised access. SAP router is a proxy in a network connection between SAP systems, or between SAP systems and external networks. SAP router acts as an extra firewall to the existing firewall (port filter). It is usually installed directly on the firewall host. The SAP router port serves as a gateway, through which connections to your firewall-protected system can be opened. You can specify the connections you want to allow in a route permission table.
If attackers detect the technology used, they will try to detect vulnerabilities related to this application.
Only use components that do not have known vulnerabilities, only use components that when combined to not introduce a security vulnerability, and ensure that a misconfiguration does not cause any vulnerabilities.
