Are software like NTRconnect and LogMeIn safe enough for businesses with sensitive data?

I have about 30 offices connected through LogMeIn Central (which is about 200 computers). When I log into their site, an email is dispatched to my phone with an 8 digit/character randomly generated value. I have to enter that value before I can access my account. I find this to be extremely secure.

Also, LogMeIn is a very reputable company and is used by companies such as SonicWall for their technical support team. I was surprised when I had a technical problem with SonicWall and their tech connected to me via LogMeIn. I expect that a lot of companies will be migrating from WebEx to LogMeIn over the next couple years.

I use the paid version of LogMeIn (LogMeIn123 and LogMeIn Central). However, I still use the FREE version of the daemon on the client computers. Annual fee for LogMeIn Central is about $250, while LogMeIn123 has a monthly fee of about $110.

Update: Their website states, "All communications by LogMeIn products use industry-standard algorithms and protocols for encryption and authentication. Nobody will be able to see or access the data transmitted between your computers - not even us." More information about their security and encryption is available at https://secure.logmein.com/products/central/security.aspx
