A service desk acts as a single point of contact for all IT-related questions and monitors each layer of client service from beginning to end. It optimizes IT service delivery by remotely monitoring networks and systems, managing incidents, performing security tasks like vulnerability scans, and ensuring seamless transitions when replacing technologies. This improves client satisfaction by keeping networks running smoothly and minimizing disruptions. While a help desk focuses on immediate user issues, a service desk has a broader focus on processes and the client experience overall. For best results, an IT provider should implement both to gain the benefits of each.
