I'm 3+ years in, other products have come along (SCCM, Kace), we still use Lansweeper for getting real work done.
Look at the
membership, a number of users (paid, too) all across the world - should tell it must do something well...
🙂Network: This number continues to drop it seems with each update. The devs are doing a good job on finding ways to keep this low enough to work across some slow lines. On a LAN, it's not something I've needed to look at. If you have slow remote sites, you can look at the Enterprise license to allow local scanning. You can tell the scan system to only look for specific internal hardware (say you don't have floppy drives, you can have that scan ignored). Or you can tell the scan server to only check for a floppy drive once a month, not every time the computer is scanned.
Software on a Windows system is discovered with remote WMI calls. Windows system's hardware is also inventoried by remote WMI calls. Other hardware, printers, Macs, NAS, phones, switches, all can be inventoried with SSH or SNMP (you can configure different authentication for each type of scan, down to the individual network or device.)
No client/agent is required. If you wish, you can have a small exe run a user logon to "ping" the scanning server to come give that person's PC a scan. In the beta 4.2, there is a new exe that can run on the PCs that does the scanning locally, and forwards the results to the scanning server (great for systems behind a firewall, or non-domain connected systems).
If you use AD credentials to operate the scan server, it can pull user information into the the Lansweeper database (you can use this info for reporting/searching). With AD credentials in use, the scan server can operate under a service account that has remote admin access to your computers to perform the WMI scans. Or you can choose to use different credentials per network - even scan a different domain's computers. I'm not sure it's best for large shops, but you give the scan server credentials to your Domain Controller's and their logs can be scanned looking for computers as the come online, the adding them to the scan queue.
With basic, standard, configuration of your systems, Lansweeper will operate securely. Without a required agent installed on all your systems (or .NET 1.1 like the Kace does...), the threat profile is reduced.
We have a good community and good support in the forums. Go for it.
