Rubix Technology
SecureDesk is a self-hosted remote support and device management platform for Windows environments, built so the operator's own infrastructure, not a third-party cloud sits in the middle of every session. It supports two connection modes: attended sessions for real-time, on-demand remote assistance where the end user is present to approve the connection, and unattended access for managing devices that aren't actively staffed, such as servers or kiosks. For deeper troubleshooting, technicians can drop into a SYSTEM-level shell to run administrative commands directly on the endpoint. The core of its design is the encryption model: both the technician's console and the remote endpoint generate their own AES-256-GCM keys, and endpoints connect outbound-only. The self-hosted relay that brokers each session only ever forwards ciphertext it holds no key for, so even the relay operator can't see or decrypt session content.Starting Price: $249/year -
