Network Security Monitoring Solution

Advanced network security threats, once inside your company, can quickly take advantage of the flat and open network. What can you do?

Network security is not simply about building impenetrable walls — determined attackers will eventually overcome traditional defences.

The most effective computer security strategies integrate network traffic analysis and security monitoring: the collection and analysis of data to help you detect and respond to intrusions.

Network security monitoring solutions add an extra level of security by monitoring wire data to protect key assets even when threats do get past your perimeter.

NetFort LANGuardian is network security monitoring software which uses wire data to ensure continuous visibility.

NetFort LANGuardian can be deployed on physical or virtual platforms. It uses network packets (wire data) as a data source so no need to install agents or client software. Look no further if you need an all-in-one network security and performance monitoring solution. Common use cases include:

  • Tracking the source of Ransomware.
  • Detecting source of malware such as Conficker.
  • Investigating reports of suspect traffic (both in and out).
  • Investigating and cleaning up after phishing emails.
  • Alerting on spoofed DNS traffic.
  • Dealing with external organizations reported malware originating from your network.
  • Inspect outgoing traffic from your network.
  • Find the source of SPAM originating from network.
  • Track down individual users downloading large volumes of data from internal shares.
  • Report on mobile device activity by MAC address.

Build security intelligence and protect your network, users and data with network traffic and security monitoring.

Getting visibility into all aspects of network and user activity coupled with instant drill down to actionable detail holds the key to improved detection and faster response for today’s sophisticated security threats. NetFort LANGuardian leverages Deep Packet Inspection (DPI) technology to transform network traffic into actionable security and operational intelligence, structured data that can be indexed, stored for long periods, easily searched and interpreted.

LANGuardian’s biggest benefit is that a non-technical user is able to drill down from a dashboard to meaningful and useful information in just a couple of clicks.

Given the recent huge increase in number and sophistication of attacks on networks today, it is absolutely critical that both network and security teams (the same person/team in many organizations) always have a centralized visibility into ALL of the activity across their networks. This visibility must be comprehensive and cover as much activity as possible but also be clear, concise and readable.

It is no longer acceptable for the security team to have to request data, to wait and NOT have a continuous visibility into all network and user activity.  Both the network and security teams need complete visibility sometimes down to a very granular level to protect the network.

LANGuardian is your ideal single pane of glass and includes rich detail on all internal traffic, events, active endpoints/servers/applications and what users are doing. Having all this data centrally at one’s fingertips initially at a high level to get the big picture and also easy to search, drill down and correlate ensures faster detection and resolution of issues.

LANGuardian includes an application level traffic analysis engine tightly integrated with a number of other key modules including an advanced network intrusion detection system (IDS) that enables real-time detection and alerting of malicious events that occur on the network.

LANGuardian seamlessly integrates data from the IDS with detailed application level and user traffic analysis to provide a unified continuous visibility, a rich single source of actionable metadata for many security and operational use cases and the ultimate single pane of glass for monitoring and troubleshooting activity on your network.

Track activity by IP or MAC address and see the actual user name associated.

Traditional network security solutions focus on the infrastructure and not on the actual user. Security teams usually have very limited visibility into internal user activity, traffic, bandwidth, applications, file transfers, access to sensitive data,  email, even Internet activity. This combined with an increasingly open and third-party-reliant business environment, weakens a company’s ability to detect and respond to the increased threat of user-targeted attacks and insider threats.

NetFort LANGuardian integrates with Microsoft Active Directory to track and report on network activity by IP address, MAC address or user name. This user centric approach ensures you know what users are doing on your network every day, can easily detect and investigate unusual or suspicious activity and go back, use the detail in the built in database for forensics, actual proof to eliminate any doubt and guesswork.

How it works

LANGuardian passively captures the traffic flowing through your network switch usually via a SPAN port or port mirror, analyses it using deep packet inspection techniques, and stores the results, events and even flows and rich metadata in one centralized database.  There are no agents, clients or logs required.
