Dell Secure Connect Gateway is an application that runs on the Management VM and is used to automate technical support for Dell servers. Secure Connect Gateway monitors your devices and proactively detects hardware issues that may occur. When a hardware issue is detected, Secure Connect Gateway automatically opens a support case with Dell Technical Support. Secure Connect Gateway automatically collects the system state information that is required for troubleshooting the issue and sends it securely to Dell. The collected system information helps Technical Support to provide you an enhanced, personalized, and efficient support experience. Secure Connect Gateway also includes a response from Dell Technical Support to help you resolve the issue.
