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.

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.

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.

Best practices: Strategies for boosting your practice’s information immunity

Physicians know how to treat human-borne viruses but are often unprepared to deal with the ones disseminated by computers. These threats, which carry legal, financial and public relations consequences, must be managed effectively to protect your practice and its patients.

Vulnerability management: Key questions you should be asking

Is vulnerability management critical for a business? Aren’t traditional security tools sufficient to protect and secure the network? Yes, to the first question and a resounding no, to the second! Every system can be made more secure and vulnerability management solutions will not only show where to secure, but how to do it and deliver the patches and updates to achieve it. This whitepaper explains why.

Vulnerability scanning: Your company's personal virtual security consultant

Managing a large and growing PC estate is no simple matter, particularly if you are doing it manually.
