SAP Cloud Connector
SAP Cloud Connector is the software component that enables SAP Business Technology Platform (BTP) to communicate securely with on-premise systems without exposing those systems directly to the internet. As SAP customers accelerate hybrid deployments, the Cloud Connector functions as a critical piece of infrastructure: controlling exactly which internal services are accessible from the cloud, enforcing encrypted reverse-proxy tunnels, and enabling BTP-based extensions, integrations, and analytics to operate against live on-premise data. It can be deployed on physical or virtual machines and supports connectivity to one or more SAP BTP subaccounts across regions. SAPinsider covers how organizations configure and secure Cloud Connector deployments across increasingly complex hybrid landscapes.
What Is SAP Cloud Connector?
SAP Cloud Connector is a lightweight, installable application that runs on Windows, Linux, or Mac OS, inside a customer’s on-premise or private cloud network. It establishes an encrypted, outbound-only reverse-proxy tunnel to an SAP BTP subaccount, meaning organizations do not need to open inbound firewall ports to connect cloud applications to internal systems. Once configured, it acts as the secure conduit for SAP BTP scenarios, including application extensions, data replication, analytics, and API-driven integrations. Multiple Cloud Connectors can connect to one or more SAP BTP regions or subaccounts, depending on landscape requirements.

What Use Cases Are Referenced?
Extending a Professional Services Timesheet Application to SAP BTP
A professional services firm built a multi-channel timesheet extension on SAP BTP, integrating data from SAP SuccessFactors, SAP S/4HANA Cloud, and two third-party systems. SAP Cloud Connector was used to link the on-premise SAP S/4HANA environment to SAP BTP in Step 1 of the build process. SAPinsider documented the end-to-end approach.
Layer Seven Security Deploys Cybersecurity Extension via BTP Cloud Foundry
Layer Seven Security’s Cybersecurity Extension for SAP now runs through SAP Build Work Zone on BTP Cloud Foundry. Setup requires a configured SAP BTP environment with connectivity through SAP Cloud Connector, a backend destination, Cloud Foundry services, and a Work Zone subscription. SAPinsider covered the architecture and deployment requirements.
Onapsis Scans SAP BTP and Cloud Connector Security Posture
Onapsis expanded its Control product line in Q4 2024 to cover SAP BTP security, including automated vulnerability scanning for Cloud Connector configurations. The solution validates security posture against SAP best practices and Onapsis Research Labs recommendations. SAPinsider reported on the product update and its implications for SAP BTP-connected landscapes.
Securing the SAP BTP Hybrid Connection Against Lateral Attack
When SAP Cloud Connector is misconfigured, attackers who compromise an SAP BTP application can pivot into on-premise SAP S/4HANA via overprivileged technical user credentials. Security leaders should configure Cloud Connector with a strict allowlist of exposed services and enforce least-privilege access for all destinations. SAPinsider outlined the attack path and layered security approach.
