We're a software company and our support staff uses Rescue to help our customers who are in a pinch and for regular maintenance. It's a tool that we use to take over servers because that's typically what most of our support works on. But we also use it to pop into an iPad for a sales rep out in the field who's struggling.
It's a SaaS model. It's an app that resides on our technicians' computers but it goes through their Cloud.
We primarily use the LogMeIn Central program for established connections. But LogMeIn Rescue is a little easier to get into when you're in a pinch. If somebody is really in trouble, Rescue has been a great supplement to the other LogMeIn products that we've used for decades.
