We use TeamViewer Enterprise with end-to-end AES-256 encryption, mandatory two-factor authentication, role-based access controls, and full session logging, centrally managed and restricted to authorized support staff only. Clicking the button below downloads the QuickSupport app, a run-only file that installs nothing and leaves no background processes. Once the session ends, the connection is permanently destroyed and the temporary file is deleted. No one can reconnect to your device after the session closes.
