Concepts and technologies for providing virtualized network monitoring as a service are provided. In an embodiment, a method can include providing, by a processor of a computer system within a service host network, a network monitoring portal to a user equipment associated with a private network. The method also can include receiving, from the user equipment via the network monitoring portal, access credentials that enable access to the private network. The method can include receiving a selection of a plurality of network monitoring service modules for monitoring the private network, and instantiating a plurality of virtual network monitoring probes that each correspond to at least one of the plurality of network monitoring service modules selected. The method can include injecting the plurality of virtual network monitoring probes within the private network, where the virtual network monitoring probes are activated in response to being injected within the private network.
