Deep Packet Inspection Software
NetFort LANGuardian provides full packet capture and deep packet inspection (DPI) of network traffic. Unlike other packet capture and DPI products, LANGuardian is a software-only product that runs on industry standard hardware and virtualized environments.
Affordable and easy to use, LANGuardian deep packet inspection gives network engineers the highest level of visibility into activity on the network. Its customizable reports and dashboards, drilldown capabilities, and powerful search provide extremely detailed information without requiring you to understand and interpret raw data packets.
LANGuardian collects network traffic data by connecting to a SPAN (monitoring) port on a network switch. It can monitor and report on internal network activity (such as access to intranet servers and file shares) as well as external activity (such as access to websites, use of cloud services, and social media activity). LANGuardian also includes an intrusion detection system that detects and reports on network security events.
The LANGuardian database
LANGuardian uses deep packet inspection to consolidate and correlate the traffic data it collects, storing it in a secure, structured built-in database that can be accessed via the browser-based user interface. Network engineers can drill down into the database and see details such as actual web pages accessed, files downloaded, bandwidth consumption, individual file share operations, and mail header fields.
The traffic database is also the foundation for LANGuardian’s advanced troubleshooting and forensic analysis capabilities. Issues and trends that cannot be identified on the basis of real-time data alone can be identified by analyzing data collected over long periods, while past incidents can be investigated based on the date and time on which they occurred. The LANGuardian database is an ideal platform for network-based analytics, compliance, and management reporting.
Detailed traffic data with no performance penalty
Since all of the information gathered by LANGuardian comes from comes deep packet inspection of traffic data captured from a SPAN port, there is no client software to install, no interaction with the devices on the network, and no impact on network performance. LANGuardian is also scalable and can be deployed anywhere from a single office to a global corporate network.
