Network Security
The foundation of a secure IT environment
A secure network is the first line of defence. We help you design, implement, and maintain a robust network infrastructure.
Infrastructure Protection
We secure communication within and outside the organisation
Implementation and configuration of modern firewalls with application control and IPS.
Dividing the network into zones to limit damage in the event of an intrusion (Zero Trust).
Secure solutions for remote work via VPN or Zero Trust Network Access.
Control exactly which devices and users are allowed to connect to your network.
Secure wireless networks with strong encryption and guest network isolation.
Protection against denial-of-service attacks aimed at taking down your services.
Why network security?
The network is the backbone of your IT environment — and without a secure network, all other security measures are vulnerable. An attacker who gains access at the network level can move laterally through your entire infrastructure, access sensitive servers and databases, and lay the groundwork for a devastating ransomware outbreak or data exfiltration.
Modern network security is about Zero Trust: the principle of never trusting a device or user by default, regardless of whether traffic comes from inside or outside. Every connection is verified, every access is restricted to exactly what is needed. Combined with VLAN segmentation and firewall zones, this minimises damage if part of the network is compromised.
Viharnis designs and implements network architectures that are both secure and scalable. We deliver full visibility and control via logging and network monitoring, and we ensure your infrastructure can grow in pace with your business without security being compromised along the way.
Zero Trust architecture
Never trust, always verify — every connection and user is explicitly authenticated.
Visibility & Control
Full insight into network traffic to quickly detect bottlenecks and intrusion attempts.
Scalability
Networks designed to grow with your business without compromising security.
Next-Gen Firewall
NGFW with application control and IPS — far beyond basic port-based filtering.
Segmentation
VLAN isolation dramatically limits damage propagation if a segment is compromised.
Secure remote access
VPN and ZTNA for safe remote working — without opening your infrastructure to the world.
Our approach
Analysis & Design
We analyse your needs and design a network architecture balancing security and performance.
Installation & Configuration
We install hardware and configure rules, VLANs, and routing.
Testing & Verification
We test the network to ensure everything works as intended and security holds.
Documentation & Handover
You receive complete documentation of the network and training in its operation.
Build a secure foundation
Let us help you secure your network for the challenges of the future.
