On-site and inter-site data networks and telecommunications
For any digital operation, a fast, stable, and secure data connection between an organization’s various locations—be they offices, production units, data centers, or mobile work points—is a fundamental requirement. The network connection between sites is more than just a channel for data traffic; it is the technological backbone on which daily operations, information flow, and business processes are built.
The quality of the data connection has a direct impact on efficiency, costs, response times, and the customer experience, whether it involves real-time data communication, accessing centralized applications like ERP systems, conducting video conferences, or copying backups to another site.
Unicorn offers services ranging from design to operation for this critical task. We establish, secure, and manage the network connections that link a company’s sites, whether through wired, mobile, or hybrid solutions, using either leased-line or modern architectures.
We work with various technologies depending on client needs and infrastructure, including:
- MPLS (Multiprotocol Label Switching): A high-availability, leased-line data connection offering dedicated bandwidth and high security.
- SD-WAN (Software-Defined Wide Area Network): A software-defined network model that provides flexible, cost-effective, and rapidly scalable connectivity, even across multiple internet service providers.
However, stable operation alone is not enough;
Secure perimeter defense is an integral part of every system design to protect business data and processes. This includes the use of firewalls, ensuring encrypted connections, and implementing DDoS (Distributed Denial of Service) protection to prevent network infrastructure from being overwhelmed.
To provide these services, Unicorn collaborates with reliable technology partners such as Cisco, Teltonika, Digi, Palo Alto, Netscout Arbor, and Avnet.
Unicorn’s goal is to provide its clients with not just a data connection, but guaranteed availability, visibility, and protection—in any infrastructure and between any locations.
The Layers of data connections – from stable foundations to network security
For companies operating across multiple sites, the IT infrastructure is not just an internal system but an interconnected ecosystem where every data movement, communication, and business process builds upon the others.
Secure and efficient data transmission can only be achieved if every level of the network is properly designed, monitored, and protected—from the physical connection and network devices to encrypted channels and perimeter defense. Our services reflect this complexity:
We don’t just connect cables and configure routers; we design and operate complete network architectures that ensure the smooth functioning of business processes, whether between two offices, a data center and a remote production unit, or across international system connections.
The following sections introduce the key building blocks from which Unicorn constructs corporate data connection solutions: from the physical structure of the network and mobile data transmission options to encrypted communication and perimeter defense solutions.
Corporate network infrastructure – the foundation of reliable data flow
The physical and logical connection of corporate systems operating at various sites requires a reliable, stable, and fast network infrastructure. Whether in an office, industrial, or mixed environment, the design and implementation of wired and wireless network connections determine how smoothly, securely, and predictably business applications operate.
The challenges are becoming more complex: due to high-bandwidth business applications (e.g., ERP systems, real-time data processing), cloud services, office mobility, and the BYOD (Bring Your Own Device) culture, corporate networks today must be not only fast but also intelligent and secure. Furthermore, in industrial environments—such as production lines or logistics centers—the need for reliability and physical resilience is even greater.
Unicorn’s team of experts develops infrastructure tailored to a company’s unique needs based on on-site surveys, network design, and standardized implementation. Beyond structured cabling, we undertake:
- The installation of switches and routers.
- The deployment of access points for wireless coverage.
- The creation of modern network segmentation solutions, such as VLANs (Virtual LANs), to create multiple isolated networks on the same physical hardware.
If required, we also configure QoS (Quality of Service) settings to prioritize business-critical traffic—such as video conferences, database usage, or VoIP calls—thereby preventing slowdowns or interruptions.
The stability, scalability, and security of our solutions are guaranteed by the device manufacturers on which Unicorn builds:
- Cisco: A market leader in network technology, providing reliable routers, switches, and SD-WAN-capable devices tailored for corporate environments.
- Teltonika: Offers robust, industrial mobile data devices that support redundant connections and remote access, even in extreme conditions.
A well-designed and implemented network infrastructure is not just a data connection but a valuable operational backbone that supports efficient work, reduces the potential for errors, and prepares the ground for higher levels of automation and digitalization.
Mobile data connections and connecting remote sites
Not every site has an established, wired data connection—especially in the case of temporary facilities, remote warehouses, external worksites, or vehicle fleets. In these instances, mobile network connections (4G/5G-based internet access) are the only rapidly deployable and reliable solution for data transmission.
With the right devices and management, this type of data connection can be used not only as a temporary solution but also as a permanent infrastructure. The challenge here is not just providing bandwidth but also ensuring the connection’s stability, encryption, and the possibility of central management.
Unicorn employs solutions that allow mobile data connections to be integrated into the corporate network just like a classic wired connection—including VPNs, secure remote access, and traffic prioritization.
Teltonika’s industrial routers enable redundant SIM management, remote reboots, automatic connection recovery, and encrypted data transmission, making them ideal for environments where no other connection is available or where operational continuity is critical. Configurations, including firmware updates and diagnostics, can be managed centrally.
If a site requires a complete mobile service and not just a device, Unicorn also offers Digi’s business telecommunication solutions, which provide reliable coverage and competitive data plans for the business segment.
Thanks to these solutions, our clients can quickly and securely connect their remote sites to the network from anywhere, allowing the company’s entire IT environment to remain unified, monitored, and scalable—regardless of where daily operations take place.
Backup – the last line of data security
A company’s data assets are one of the most critical elements of its operation. Lost, damaged, or illicitly modified data can cause serious business harm—from operational shutdowns to legal consequences. The purpose of a backup is to enable the safe and rapid recovery of data in such situations. This is not merely a technical issue but a fundamental requirement for continuous business operations.
Modern backup systems go far beyond periodic data copying. They can back up data from various environments (physical servers, virtualized systems, cloud platforms), manage versions, automatically verify backup success, and even provide protection against ransomware.
Unicorn builds its backup solutions on Veeam technologies, which provide an industry-recognized, reliable, and scalable platform. During system design, we consider business needs, backup windows, recovery objectives (RPO and RTO), and the available infrastructure. This way, our clients can always count on their data being safe—even in the event of unexpected incidents.
Secure inter-site connections – VPN, SD-WAN, and perimeter defense
The network connection between sites is a ritical area not only for operations but also for the security of corporate data. During data transmission between different locations, it must be ensured that sensitive information travels through encrypted channels and that neither external nor internal risks threaten business processes.
Therefore, the use of VPN (Virtual Private Network) and SD-WAN solutions is a fundamental requirement in modern network architectures, as they also provide flexibility and central management capabilities. The challenge with these connections is not only the technical implementation but also the coordination of latency, redundancy, traffic routing, and fault management.
Compared to traditional MPLS connections, modern SD-WAN networks provide intelligent routing, load balancing, and real-time traffic monitoring—even across the lines of different internet service providers. Unicorn builds inter-site connections that align with business priorities. Data security is guaranteed by the combination of encrypted VPN channels, application-based traffic control, and firewall-based perimeter defense.
Such systems allow, for example, the connection to a central ERP system to take a faster route, while background updates receive lower priority.
The state-of-the-art devices and software for these solutions are provided by our technology partners:
- Cisco – SD-WAN and VPN devices, secure connections, and network redundancy.
- Palo Alto – Next-generation firewalls offering application-level traffic filtering, SSL inspection, and centralized management.
The result is a flexibly scalable, high-availability, and secure data connection that supports the company’s operations long-term—whether between a few or several dozen sites.
DDoS protection and traffic analysis – visibility and responsiveness at every level
Network infrastructure security cannot end at the firewall. Targeted, large-scale overload attacks—especially DDoS-type attacks—pose a serious threat even to well-protected systems. During these attacks, perpetrators flood a specific target with a massive amount of data traffic, making normal operation impossible for hours or even days. Such a shutdown can cause not only business losses but also reputational damage and even contractual penalties.
Classic perimeter defense tools (e.g., firewalls) are often powerless against this level of load because they operate in a stateful manner, meaning they can be quickly overwhelmed by too many connections. Effective defense requires specialized, stateless systems that can identify, filter, and block such attack patterns in real-time—before they reach the internal network.
For such cases, Unicorn employs industrial-grade DDoS protection systems from Netscout Arbor and Avnet.
These are capable of:
- In-depth, packet-level traffic analysis.
- Behavior-based threat detection.
- Automatic comparison with international threat intelligence databases.
The systems support automated responses during an attack and provide detailed reports and alerts for system administrators. They also offer long-term monitoring and traffic analysis functions, allowing IT operations not only to react to events but also to take preventive measures. DDoS protection is critically important for all interconnected systems and sites: even private VPN connections and SD-WAN architectures can only operate smoothly if protection against overload attacks is ensured and active.
