In one implementation, a network device provides a single signoff service to one or more endpoints in software as a service (SaaS) sessions. The network device is configured to monitor a session between a software as a service (SaaS) provider and an endpoint device and to identify a network event trigger associated with the session. In response to the network event trigger, a signoff message is generated to the SaaS provider by the network device. The SaaS provider is configured to purge the session in response to the signoff message.
