By definition, network security describes the technical and organizational protection of the internal IT infrastructure with all its data, systems, devices, and applications to enable secure digitalization. These security mechanisms not only protect the data center, but also all locations and the cloud itself. Effective network security fends off unauthorized access, data manipulation or data theft with blackmail, system paralysis (DDoS attacks), and other damage caused by hackers, malware, and viruses.
It ensures that data is exchanged confidentially and with integrity and is always available via VPN (Virtual Private Networks) or ZTNA (Zero Trust Network Access). However, secure networks are created primarily through comprehensive information on network security and network protection, as well as targeted measures to enforce cyber protection policies at all levels. The best way to get started right now is with LANCOM insider knowledge on the subject of network security!
Enhanced network security through cross-system monitoring with telemetry API
The new telemetry API enables programmatic access to all data collected in the LANCOM Management Cloud and allows integration into external observability, monitoring, and security systems. This makes centralized, cross-system monitoring possible, allowing security-relevant anomalies and trends to be identified at an early stage. Targeted queries and access to up to 30 days of historical data accelerate the analysis of disruptions and security incidents, providing transparent insight into the status and security of your network infrastructure. At the same time, the interface lays the foundation for future native enhancements, such as advanced metrics in “My Dashboards” and improved tools for troubleshooting and security analysis.
Network security according to NIS2
The EU has given network security a new, even higher priority with the new NIS2 directive: Because without state-of-the-art cybersecurity, attacks on critical infrastructure can have serious consequences for society and the economy. NIS2 requires many adjustments for some companies. We show you to whom NIS2 applies, what is required, and how to implement the policy.

We look forward to meeting you in person and talking about secure networks in retail.
Basics of network security
Basic know-how on IT security in the network
Due to the increasing reports about cyber attacks on companies, everyone is aware of the fact that one should secure one's network. In theory. However, many people struggle with what professional cyber protection or network protection looks like in concrete terms and what is involved in it. This is an overview of the essential basics.
Secure edge computing
Secure IT starts at the edge of the network
Secure edge computing brings computing power and security mechanisms directly to where the data is created — at the edge of the network. Local firewalls not only handle network protection but also serve as platforms for isolated software applications. This allows time- and information-critical processes to run directly on-site. The result: higher speed, lower latency, and stronger protection of confidential information.
Hands-on network security
Network security in implementation
You are aware of the importance of IT security, but you do not know where to start or whether you have considered everything important? Through many years of experience in the protection of IT systems, we have some advice directly from the field: the "hands-on" show you where you can tackle.
Network security made simple
Support for network security in enterprises
With LANCOM at your side, the weight of the responsibility of being an IT admin in charge of security is lifted from your shoulders: With numerous support offerings – including a user-friendly firewall interface, cloud-managed security, as well as support and training courses – you will receive competent guidance on your way to a secure network.
Network security & UTM
How Unified Threat Management protects your IT network
Thanks to Unified Threat Management, network security can be left to the LANCOM R&S®Unified Firewalls with a clear conscience: The UTM firewalls combine the highest-class security functions, such as sandboxing, machine learning, IDS /IPS, SSL inspection, deep packet inspection, and many more, in a single device, thus ensuring the best possible protection.
Network Threats
Types of cyber attacks and appropriate protective measures
Trojans, phishing, viruses, advanced persistent threats, DDos attacks – cybercriminality has now taken on many forms and is becoming increasingly clever and insidious. All the better if you know the most common network threats and how to protect your network against which form of cyber attack.
Quick network protection
Securing networks with inventory funds
As an IT admin, being responsible for network security is a considerable burden. But don't worry, we are at your side. Step-by-step towards greater network security. This includes router and firewall settings, LAN security, Wi-Fi settings, and general awareness throughout the company for the importance of IT security.
More security due to transparency
Advanced Deep Packet Inspection software
The LANCOM R&S®Unified Firewalls use the R&S®PACE 2 Deep Packet Inspection (DPI) engine to optimize the management of individual applications in the constantly growing network traffic. That sounds good, but also dry? Let us introduce you to how the software works and how it significantly increases the IT security of corporate networks.
