What does the company do well? Their remote access solution simply just works. Our company uses it on almost all of our installations as well as our home PCs. What's especially nice are their client apps, we can remote support our customers using our phones or with the client app on the pc without having to go to their website. They also offer two factor authentication to make it that much more secure.
What does the company not do well? The only problems we have with them are minor. Their solution can no longer be installed on Windows XP (yes, some of our sites still use this). I also wish they had been more assertive in establishing themselves as PCI compliant early on, this caused some of our customers to not allow logmein.
What do you wish you had known about the company before using? We have been using logmein almost since their inception when it was still free. I wish we had known about how they were going to change their pricing models over the years, but now we are happy and their pricing is very competitive compared with similar solutions
