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!
Secure container management
With your own Docker containers, you can run applications and specialized software quickly, in isolation, and independently of the system environment directly on your firewall. This creates a flexible platform for additional functions—such as vulnerability scanners, securing legacy systems, secure remote access, or distributed computing. Starting with LCOS FX 11.2, you can conveniently manage your containers via the REST API of the LANCOM R&S® Unified Firewall (with an active SAG Basic or SAG Full license). When updating the firewall operating system, container contents are preserved. Containers and networks can be created and monitored in real time, rules can be defined precisely, and configurations can be automatically restored from backups. LMC add-ins and interactive API documentation make it easier to get started. This lays the foundation for secure edge computing: Applications run securely and efficiently directly on site, enabling fast and protected data processing.
School networks & Wi-Fi
Schools bring two particularly valuable goods together: Children and education. An investment in modern schools is an investment in the future. Ensuring modern digital learning and access to education in times of crisis demands future-proof school Wi-Fi. LANCOM addresses the requirements for today's school networks and helps educational institutions to implement them quickly, securely, compliant with data protection, and without great expense.

With four licensing models and flexible terms, you can tailor your firewall precisely to your needs.
How well are European SMEs really prepared for current cyber threats? And which measures actually help improve IT security in a sustainable way?
Our deep dive, “Security awareness in European SMEs,” on April 9 from 11 to 11:45 a.m. highlights the key findings of the it-sa Cyber Security Barometer 2025 and shows where mid-sized companies stand today – and which steps are now critical. Learn why, despite a growing threat landscape, many key protective measures are still insufficiently implemented, what role budgets, responsibilities, and knowledge play, and how modern approaches – such as AI-supported defense – can strengthen security strategies.
Using a practical example from the LANCOM IT Security Ecosystem, we will also demonstrate how IT security can be implemented holistically and realistically in mid-sized businesses.
Your benefits:
- Context and interpretation of current study data and trends
- Practical guidance for prioritizing your security measures
- Actionable strategies for a future-proof IT security architecture
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.

Network security according to NIS2
Quickly understand and implement the new requirements
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 prepare well for it.
