Managed network services are networking applications, functions and services that enterprises outsource to be remotely operated, monitored and maintained by a managed service provider (MSP).
Managed network services range from basic network access and transport services like traditional leased WAN and LAN lines to newer software-defined WAN (SD-WAN) connections and virtual network services. Beyond network access and transport services, the variety of available managed services includes the following examples:
• WAN optimization
• unified messaging
• network administration
• network provisioning
• cabling installation
• network monitoring
• managed security firewalls
• virtual private networks (VPNs)
