Network security

From fundamentals to hands-on

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!

LANCOM Trusted Access (LTA)

LANCOM Trusted Access stands for trustworthy remote access for employees to their corporate network: This enables secure access to applications and work materials in the office, at home, or on the road, and modern hybrid working from anywhere and at any time is protected in a contemporary way. The LANCOM Trusted Access solution scales with the security requirements of your organization, from cloud-managed VPN and multiple expansion stages to a zero-trust security architecture for comprehensive network security. Based on granular access rights, users only receive access authorization to applications that have been assigned to them (zero-trust principle). Existing user management systems (Active Directory) can be fully integrated into the LANCOM Management Cloud (LMC). Alternatively, the LMC offers internal user management for smaller networks. LANCOM Trusted Access is 100% GDPR-compliant and scales for small businesses as well as for very large networks with several thousand users.
