My take on remote support software.
TeamViewer Host
$750 1-time fee. But it only is good for that version. And versions don't intermingle. If you upgrade your server, you must upgrade all your clients. :-(
Remote Utilities
$500 1-time fee. Windows only. No mac support. :-(
LogMeIn Rescue
$1299 per year :-( But it's a final solution with reboot into safe mode plus other goodies. ;-) Many large support companies use.
Ammyy
I can't figure out the pricing. I think it's around $30 per remote pc. It only works on windows. No Mac support. :-(
CrossLoop
No longer available.
Aero Admin
$280 1-time fee. Not seemless. No service. Must config via Windows task scheduler. Yuck. :-(
Join.Me
$240 per year. I've had trouble with UAC, no mouse moving, etc. :-(
RAdmin
$50 per client :-(
GoToAssist
$850 per year. But it's enterprise ready.
Bomgar
$7000 1-time fee. Enterprise ready.
ServiceConnect
$350 1-time fee. :-) Many features.
GovernLan
$950 1-time fee. :-) Seems to be just for LAN/AD/MPLS/VPN. WAN capabilities limited.
DameWare
$350 1-time fee. :-) SolarWinds portfolio. :-) WAN capabilities limited.
CentraStage / Autotask
$24 per node annually. I'm not sure but many are upset at Autotask. I'll choose to stay away.
GFI Max
$12 per computer annually & $150 per server annually.
Continuum
$15 per computer annually & $175 per server annually or little higher than GFI Max is all I found. But they have an interesting white label tech support with 24 hour availability.
LabTech
Can't find much but I know it's similar to those above. Price per node per month.
