IT infrastructure and network security in Vilnius
Proplius designs, installs and maintains IT infrastructure, network security solutions, Linux servers, VPN, Wi-Fi, Proxmox virtualization and secure remote access for homes, offices, warehouses, commercial premises and technical sites in Vilnius and surrounding areas.
This field includes not only connecting equipment, but also proper network architecture, server logic, secure remote access, backups, network segmentation, stable Wi-Fi coverage and the ability to maintain the infrastructure in the long term.
In one site, this may mean a stable home network, secure access to cameras, NAS or smart systems; in another, it may be a business network, server room, multi-location VPN, VLAN segmentation, backups and centrally managed infrastructure. Each solution is selected according to the real conditions of the site, user needs and future expansion possibilities.

Long-term experience with networks, Linux servers, telecommunications infrastructure and complex IT solutions makes it possible not just to select equipment, but to build a technically correct system that remains stable, secure, clearly manageable and reliable in the long term. Proplius sees IT infrastructure as the technical foundation on which internet connectivity, cameras, alarm systems, access control, servers, workstations and other site systems depend.
Experience and practical approach
We have been working in IT and networking for more than 25 years — from computer repair, workstation preparation and local infrastructure maintenance to the design of complex networks, server rooms, multiple sites and business infrastructure. This experience allows us to look at IT systems not only theoretically, but practically: how a solution will operate in a real environment, how it will be administered and how it will behave under load or during failures.
Experience in telecommunications with DSL, FTTH, GPON and LAN networks has provided a strong practical understanding of how stable connectivity infrastructure is built, why network problems occur and how complex faults can be diagnosed efficiently. This is important both for private sites and business environments, where network stability, secure access and server reliability directly affect daily use.
Today, Proplius designs and maintains IT infrastructure: Cisco networks, Linux servers, Proxmox virtualization, VPN, Wi-Fi infrastructure, server rooms, network segmentation and secure remote access. Solutions are selected so that the infrastructure remains stable, clearly manageable, secure and suitable for long-term use.

Why a network must be designed correctly
An unstable network often becomes the weakest point of the entire technical infrastructure. When internet connectivity drops, Wi-Fi becomes unstable, cameras stop working, or access to servers, accounting, security or other systems is interrupted, it affects not only convenience but also the real functionality of the site. These problems are often not caused by a single faulty device, but by incorrectly designed or chaotically expanded infrastructure.
A network should therefore be planned as one integrated system, not as a collection of separate devices. It is important to properly assess network segmentation, server architecture, Wi-Fi coverage, backups, power redundancy, firewalls, VPN and secure remote access. A correctly designed infrastructure helps the system operate reliably, makes faults easier to diagnose, improves access security and allows the system to expand safely in the future.

Network infrastructure
Reliable IT infrastructure starts with a properly designed network. Proplius works with Cisco routers, switches and other network solutions that help ensure stable connectivity, clear management and the ability to expand the infrastructure securely in the future.
Properly planned VLAN segmentation makes it possible to separate workstations, servers, IP telephony, video surveillance cameras, access control, guest Wi-Fi networks and other infrastructure elements. In private sites, this separation can be useful for cameras, smart devices, a home server or a guest network, while in business environments it is important for employee access, servers, telephony and accounting systems.
We design networks for homes, offices, commercial premises and multiple sites with secure remote access, VPN solutions, centralized management and stable Wi-Fi coverage. Wireless infrastructure is selected according to the layout of the premises, number of users, expected load and real working or usage conditions, so that the connection remains reliable not only near the router, but in all important areas.

Servers and virtualization
We design, install and maintain server infrastructure when stable operation, secure data storage, convenient administration and future scalability are important. Servers can be used for file storage, internal systems, remote access, backups, camera archives, websites, email or other site and business services.
We work with the following solutions:
Debian Linux servers — for stable and secure server infrastructure.
Proxmox virtualization — for managing multiple virtual servers on one physical infrastructure.
VPN servers — for secure remote access to the site network, servers and internal systems.
File servers — for centralized storage of documents, projects, archives and shared data.
Nextcloud and Samba solutions — for convenient file sharing, synchronization and work across multiple devices.
DNS, WEB and email servers — for internal or public services.
RAID storage solutions — for improved storage reliability and lower risk of losing important data.
Backup solutions — to protect important data from failures, human errors and unexpected incidents.
Server monitoring and maintenance — for checking system load, disk health, service availability and security updates.
A properly designed server infrastructure helps manage data more reliably and avoid situations where the failure of one device stops important services. The key is not only to install a server, but also to correctly plan its purpose, access rights, backups, storage architecture and long-term maintenance.

Server rooms and infrastructure
A well-organized server room, technical rack or network node is the foundation for stable operation of networks, servers, video surveillance, access control and other IT systems. Even high-quality equipment will not work reliably if cables are connected chaotically, there is no clear labeling logic, power backup is missing or no space is planned for future expansion.
We work with the following infrastructure solutions:
Server racks — for organized installation of network equipment, servers, NVR, UPS and other devices.
Patch panel systems — for clear cable termination, labeling and easier network maintenance.
UPS power backup — to keep servers, network equipment, cameras and other important systems operating during power outages.
PoE infrastructure — to power IP cameras, access control devices, Wi-Fi access points and other network equipment over Ethernet cabling.
NVR and video surveillance integration — to connect cameras, recording devices and network infrastructure into a stable system.
Backup solutions — to enable recovery of important data, configurations and systems in case of failure or incident.
Cable labeling and documentation — for faster diagnostics, clearer maintenance and easier future expansion.
Network equipment layout — so that equipment remains accessible, properly cooled and safe to operate.
A properly organized infrastructure makes it easier to diagnose faults, administer systems securely and avoid situations where one unclear cable or poorly managed connection stops an important service. This is relevant not only for business sites, but also for private homes where cameras, alarm systems, Wi-Fi, NAS, smart devices or remote access are used.

Why we use Cisco and professional equipment
In IT infrastructure, stability, reliability and secure network management are the most important factors. That is why, in sites where cameras, servers, VPN, Wi-Fi, access control or other important systems are used, priority is given to professional network equipment designed for long-term operation, higher loads, clearer administration and a more secure network architecture.
Low-cost consumer-grade solutions often become the weakest point of the infrastructure. At first, they may seem sufficient, but in real use problems quickly become visible: unstable connectivity, unreliable VPN, Wi-Fi interruptions, poor load handling, limited network segmentation options or failing cameras and other network devices.
For this reason, we often use Cisco and other professional equipment in network projects, as it allows us to build a more stable, secure and easier-to-maintain infrastructure. Properly selected equipment helps ensure reliable connectivity, network segmentation, VPN operation, access control and the ability to expand the system in the future.

What a typical infrastructure looks like
A typical IT infrastructure starts with a properly organized server room, technical rack or network node where network cables are terminated, a patch panel system, professional switches, a router, UPS power backup, servers, NVR recorders and other important infrastructure equipment are installed. This setup makes the network easier to manage, faults easier to diagnose and the system more convenient to maintain in the future.
The network may use VLAN segmentation to separate workstations, servers, IP telephony, video surveillance cameras, access control, guest Wi-Fi and smart devices. This improves security, reduces unnecessary network load and limits the risk that a problem in one system will affect the entire site infrastructure.
For virtualization, a Proxmox hypervisor is often used, allowing separate virtual systems to run independently: VPN servers, file servers, accounting or business systems, backup solutions, remote access or services for multiple sites. This architecture helps use server resources more efficiently, makes systems easier to administer and allows the infrastructure to scale flexibly as needs grow.
