GFI LANguard Network Security Scanner (N.S.S.) checks
your network for all potential methods that a hacker
might use to attack it. By analyzing the operating
system and the applications running on your network,
GFI LANguard N.S.S. identifies possible security holes.
In other words, it plays the devil's advocate and
alerts you to weaknesses before a hacker can find them,
enabling you to deal with these issues before a hacker
can exploit them.

GFI LANguard N.S.S. scans your entire network, IP by
IP, and provides information such as service pack level
of the machine, missing security patches, wireless
access points, USB devices, open shares, open ports,
services/applications active on the computer, key
registry entries, weak passwords, users and groups, and
more. Scan results can easily be analyzed using filters
and reports, enabling you to proactively secure your
network - for example, by shutting down unnecessary
ports, closing shares, installing service packs and
hotfixes, etc.

GFI LANguard N.S.S. is also a complete patch management
solution. After it has scanned your network and
determined missing patches and service packs - both in
the operating system and in the applications - you can
use GFI LANguard N.S.S. to deploy those service packs
and patches network-wide. It can also deploy custom
software network-wide.
