Patch non-Microsoft applications

GFI LANguard also offers patch management support for non-Microsoft software, enabling administrators to detect, download and deploy missing patches for supported applications in the same way as is done for Micro
soft updates. GFI LANguard offers patch management support for many popular applications like Apple QuickTime, Adobe Acrobat, Adobe Flash Player, Adobe Reader, Mozilla Firefox, Java Runtime and others.
Deploy custom software and scripts
Besides providing automatic patch management, GFI LANguard permits the network-wide deployment of any custom software and scripts that can run silently.
Spotlight on PCI DSS and the Security Curve
Discover what the Payment Card Industry Data Security Standard (PCI DSS) is and why organisations that hold, process or exchange credit card info need to comply. This webinar will walk you through GFI's understanding of the PCI DSS requirements, and how the GFI product line can assist you to meet PCI compliance.
Vulnerability Management
GFI LANguard performs over 15,000 checks on your operating system, virtual environments and installed applications using vulnerability check databases such as OVAL and SANS Top 20. GFI LANguard allows you to analyse the state of your network security, what the risks are, how exposed your network is and how to take action before it is compromised.
Network and Software Auditing
GFI LANguard’s network auditing functionality gives you a detailed analysis of what is happening on your network – which applications or default configurations are posing a security risk. With GFI LANguard, you get a complete picture of what applications are installed, the hardware on your network, the state of security applications (AV, anti-spam, firewalls, etc.), what ports are open, any existing shares and services running on your machines.
Assets Inventory
GFI LANguard allows you to create an assets inventory of every device on your network; be they servers and workstations, virtual machines or IP-based hardware such as routers, printers, switches and so on. Asset inventories help you identify devices attached to your network that you were unaware of or had forgotten and these, unless properly patched and secure, could become entry points for hackers and malware.
Change Management
The best way to maintain a secure network over time is to know exactly what’s happening on your network. Changes to configurations that could have security implications, new applications that are installed, services that are started/stopped are all events that an administrator needs to know about. GFI LANguard gives you a complete history of network changes that are relevant to the security of your network and sends notifications when these occur.
Risk Analysis and Compliance
GFI LANguard makes it easier for the administrator to know what needs to be fixed with urgency. Security issues are rated by their severity level and each computer is given a risk and vulnerability rating so that you know where the main problems on your network are. GFI LANguard provides numerous executive, technical and statistical reports that help you to understand what is happening on the network, to prioritize remediation operations efficiently and to prove, if required, that the network is secure.

Patch Management for Microsoft Operating Systems and Applications
GFI LANguard’s patch management feature scans automatically, or on demand, your network and gives you all the functionality and tools you need to effectively install and manage patches on all machines across different Microsoft operating systems and products in all languages supported by the vendor.
GFI LANguard allows auto-downloads of missing patches as well as patch roll-back, resulting in a consistently configured environment that is secure against vulnerabilities.
Patch Management for Other Applications
GFI LANguard offers patch management support for other (non-Microsoft) software, enabling administrators to detect, download and deploy missing patches for supported applications in the same way as is done for Microsoft updates. GFI LANguard offers patch management support for many popular applications like Apple QuickTime, Adobe Acrobat, Adobe Flash Player, Adobe Reader, Adobe Shockwave Player, Mozilla Firefox, Mozilla Thunderbird, Java Runtime and others.
With GFI LANguard, not only is it possible to patch third party applications, but also to upgrade to their latest versions (i.e., if an old version of Adobe Flash is detected, GFI LANguard will provide an option to either upgrade to the latest version or to apply all patches for that version).
GFI LANguard is the first solution that automates patching for all major web browsers running on Windows systems: Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Apple Safari and Opera Browser.
Deploys Custom and Third Party Software and Patches Network-wide
Besides deploying patches and service packs, GFI LANguard also enables you to easily deploy third party software or patches network-wide. You can use this feature to deploy client software, and update software, virus updates and more; practically any application that can run silently can be pushed in the network using GFI LANguard.
NEW! Agents Technology
GFI LANguard can be configured to run either in agent-less or agent-based mode. The agents technology enables automated audits and distributes the scanning load across client machines. The administrator simply needs to define the network perimeter and provide credentials to enable automatic network discovery, agent deployment and auditing of the client machines. Manual intervention is necessary only when fine-tuning is required. This feature provides the following benefits:
- High speed: Scan hundreds or thousands of machines in just few minutes
- Automation: Agents update the client status on server on a regular schedule. Every time the application is opened, users can analyse a complete and up-to-date network security overview
- Scalability: Due to distributed load, it is possible to scan more machines in one go, even in WAN environments
- Accuracy: Local scans have less failure points than remote scans; agents will continue to work even when computers are not connected to the network.
Automatic Remediation of Unauthorised Applications
Remediation operations can be triggered automatically at the end of scheduled scans. Apart from reporting on all installed applications, GFI LANguard allows the user to define which applications are authorised or not authorised to be installed on the network. This list of applications can be easily defined for each scanning profile using the Applications Inventory Tool. During a scan, any unauthorised applications are identified and (optionally) uninstalled automatically by GFI LANguard. An integrated Auto-Uninstall Validation tool is provided to help identify which of the detected applications support silent uninstall and can thus be safely and automatically uninstalled.
Remote Desktop Connection
GFI LANguard allows the useful option of a remote desktop connection to fix security issues on scanned computers that cannot be fixed automatically.
Vulnerability Assessment
During security audits, over 45,000 vulnerability assessments are made - scanning the network IP by IP. GFI LANguard gives you the capability to perform multi-platform scans (Windows, Mac OS, Linux) across all environments - including Virtual Machines and to analyse your network’s security set-up and status. GFI LANguard gives you the power to identify and correct any threats before hackers can exploit them.
Set up your own Custom Vulnerability Checks
GFI LANguard allows you to easily create custom vulnerability checks through simple wizard-assisted set-up screens. The wizard is powerful enough to allow building of complex vulnerability checks and the scripting engine is compatible with Python and VBScript. GFI LANguard includes a script editor and debugger to help with script development.
Extensive, Industrial Strength Vulnerabilities Database
GFI LANguard ships with a complete and thorough vulnerability assessment database, including standards such as OVAL (5,000+ checks) and SANS Top 20. This database is regularly updated with information from BugTraq, SANS Corporation, OVAL, CVE and others. Through its auto-update system, GFI LANguard is always kept up-to-date with information about newly released Microsoft security updates as well as new vulnerability checks issued by GFI Software and other community-based information repositories such as the OVAL database.
Identify Security Vulnerabilities and Take Remedial Action
GFI LANguard scans computers, identifies and categorizes security vulnerabilities, recommends a course of action and provides tools that enable you to solve the problem. GFI LANguard comes with a graphic threat level indicator that provides an intuitive, weighted assessment of the vulnerability status of a scanned computer or group of computers. Wherever possible, a web link or more information on a particular security issue is provided - such as a BugTraq ID or a Microsoft Knowledge Base article ID.
Helps Ensure Third Party Security Applications Offer Optimum Protection
GFI LANguard integrates with over 1,500 critical security applications of the following categories: antivirus, antispyware, firewall, anti-phishing, backup client, VPN client, URL filtering, patch management, web browser, instant messaging, peer-to-peer, disk encryption, data loss prevention and device access control. It provides reports on their status, e.g., if antivirus is enabled and up-to-date, the firewall is turned on, the status of backup software, a list of which instant messaging or peer-to-peer applications are installed in your network, etc. It also rectifies any issues that require attention, e.g., trigger antivirus/antispyware update, start antivirus/antispyware scans, enable antivirus/firewall, or uninstall peer-to-peer, etc.
Easily Creates Different Types of Scans and Vulnerability Tests
You can easily configure scans for different types of information, such as open shares on workstations, security audit and password policies, and machines missing a particular patch or service pack. You can scan for different types of vulnerability to identify potential security issues. These include:
- Open ports: GFI LANguard scans for unnecessary open ports and checks that no port hijacking is in force
- Unused local users and groups: GFI LANguard removes or disables User Accounts which are no longer in use
- Blacklisted applications: With GFI LANguard, you can identify unauthorised or dangerous software and add to blacklists of applications you want to associate with a high security vulnerability alert
- Dangerous USB devices, wireless nodes and links: GFI LANguard scans all devices connected to USB or wireless links and alerts you of any suspicious activity
Network and Software Auditing
GFI LANguard’s Network Auditing gives you a comprehensive view of your network - what USB devices are connected, what software is installed, any open shares, open ports and weak passwords in use, and hardware information. The solution's in-depth reports give you an important and real-time snapshot of your network's status. Scan results can be easily analysed using filters and reports, enabling you to proactively secure the network by closing ports, deleting users or groups which are no longer in use, or disabling wireless access points.
Hardware Auditing
GFI LANguard shows detailed information about the hardware configuration of all the scanned machines on your network. All devices from the Device Manager tool from Windows operating systems are retrieved, including motherboard, processors, memory, storage devices, display adapters and much more. Using network history view, you can now check whether any hardware was added or removed since the last scan.
Automatically Receive Alerts of New Security Holes
By default, GFI LANguard generates a daily digest report that contains all relevant security changes that occurred on your network that day. Any new security holes or security set-up changes discovered on your network are emailed to you for analysis. This enables you to quickly identify newly-created shares, installed services, installed applications, added users, newly-opened ports and more. GFI LANguard will generate specific reports and email notification whenever there are software or hardware changes detected within the audited network. The reports also show what remediation operations were performed.
Check to Ensure Security Auditing is Enabled Network-wide
GFI LANguard checks if each XP/2003/VISTA/2008/2008 R2/7 machine has security auditing enabled. If not, GFI LANguard alerts you and allows you to enable auditing remotely. Security event auditing is highly recommended as it detects intruders in real time.
Scan and Retrieve OS data from Linux Systems
It is possible to remotely extract OS data from Linux-based systems and scan results are presented in the same way as for Windows-based computers. This means that both Linux and Windows-based computers can be analysed in a single scanning session! GFI LANguard includes numerous Linux security checks including rootkit detection. GFI LANguard can use SSH Private Key files instead of the conventional password string credentials to authenticate to Linux-based target computers.
Additional Features
New! Powerful Interactive Dashboard
GFI LANguard has a new powerful and interactive dashboard that processes all security audits ever made to the network. It provides a summary of current network security status and a history of all relevant changes in the network over time. It also drills down through information starting from network-wide security sensors to individual security scan results.
Multiply the Value of GFI LANguard with Powerful Reporting
Reports are designed to satisfy the requirements of both management and technical staff. In the latest version of GFI LANguard, reports are integrated within the main application. All reports are based on a computer’s current status, and not on specific scans. These reports can be exported to popular formats like PDF, HTML, XLS, XLSX, RTF and CVS, and can be scheduled and sent by email. They can also be used as a template to create new custom reports and are fully re-brandable.
Helps You Comply with PCI DSS and Other Regulations
All businesses handling cardholder data, regardless of size, have to be fully compliant with strict security standards drawn up by the world’s major credit card companies. GFI LANguard provides complete vulnerability management coupled with an extensive reporting. That makes GFI LANguard an essential, highly cost-effective solution for your organisation to safeguard your network and gauge the effectiveness of your PCI compliance program.
Silent Installation Support
You can perform an unattended default installation of GFI LANguard on multiple computers in the background without any user interaction or intervention.
New! Network Discovery Not Bound by License Limitations
With the latest version of GFI LANguard, license slots are no longer required for all computers and devices in the scan results database. Only the ones that are scanned beyond network discovery are bound by license limitations.
Predefine Authentication Details
GFI LANguard allows you to store separate authentication details for every target computer on your network, avoiding the need to specify authentication credentials prior to every scan. In a single scanning session, it is possible to audit all the targets in your network, even if they require different authentication details and/or methods.
New! Full Text Search Support
GFI LANguard makes it possible for users to instantly locate the information they are interested in. Searching the scan results is now as easy as searching on the Internet. The search displays instant results with links to relevant items. You can search for both current and past events and for specific items like vulnerabilities, installed applications, missing patches etc. Moreover, you can save and print search reports.
Support for Virtual Environments
Organisations that use or plan to use virtualisation on their network can install and use a range of GFI products with confidence. GFI LANguard supports and runs on the most common virtualisation technologies in use, namely VMware, Microsoft Virtual Server, Microsoft Hyper-V, Citrix and Parallel. It also offers detection of virtual machines hosted by the scanned computer.
