Network Security Scanner & Port Scanner

Automatically detect security vulnerabilities on your network
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.

Provides in-depth information about all machines/devices
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.

Patch management
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.
