Patch management: Fix vulnerabilities before an attack

Patch management is vital to your business. Network security breaches are most commonly caused by missing network patches. GFI LanGuard scans and detects network vulnerabilities before they are exposed, reducing the time required to patch machines on your network. GFI LanGuard patches Microsoft ®, Mac® OS X®, Linux® and more than 60 third-party applications, and deploys both security and non-security patches.


Network auditing: Analyze your network centrally

GFI LanGuard provides a detailed analysis of the state of your network. This includes applications or default configurations posing a security risk. GFI LanGuard also gives you a complete picture of installed applications; hardware on your network; mobile devices that connect to the Exchange servers; the state of security applications (antivirus, anti-spam, firewalls, etc.); open ports; and any existing shares and services running on your machines.


Vulnerability assessment: Discover security threats early

More than 60,000 vulnerability assessments are carried out across your networks, including virtual environments, mobile and network devices. GFI LanGuard scans your operating systems, virtual environments and installed applications through vulnerability check databases such as OVAL and SANS Top 20. GFI LanGuard enables you to analyze the state of your network security, identify risks and address how to take action before it is compromised.
