Secure Networking

Mission-critical networks built to last.

Service providers, telcos, and datacenters operate at a scale and complexity where network failures are not inconveniences — they are incidents. Nomios has spent over two decades engineering, securing, and operating the networks that cannot go down.

Introduction

We have been doing this since before it was called secure networking

Nomios grew up building and operating carrier-grade networks for some of Europe's most demanding environments. Telcos running national infrastructure. Datacenters handling petabytes of traffic. Internet exchanges where milliseconds matter and redundancy is not optional. That operational heritage shapes everything we do.

Today we bring that same engineering depth to an increasingly complex challenge: networks that must perform flawlessly, scale continuously, and remain secure against an evolving threat landscape — all at the same time, without compromise on any dimension.

What we do

Five core networking disciplines

Deep technical expertise across the layers that matter most to service providers, telcos, and datacenter operators.

icon Routing & switching infrastructure

Routing & switching infrastructure

Carrier-grade routing and switching architecture for service providers and datacenters — from core network design to edge deployment and everything in between.
icon DDI — DNS, DHCP & IPAM

DDI — DNS, DHCP & IPAM

The foundational services that every network depends on. Reliable, scalable, and secure DDI infrastructure for service providers managing millions of subscribers and IP addresses.
icon Network visibility & monitoring

Network visibility & monitoring

You cannot manage what you cannot see. Full-stack network visibility across flows, performance, and anomalies — giving operations teams the intelligence to act before customers notice.
icon Next-generation firewalling

Next-generation firewalling

High-throughput NGFW for service provider and datacenter environments — where policy complexity, connection rates, and performance requirements go far beyond what enterprise-grade deployments demand.
icon DDoS protection

DDoS protection

Volumetric DDoS mitigation at the scale that service providers and hosting operators face — protecting infrastructure and downstream customers from attacks that can reach hundreds of gigabits per second.
icon PON & interconnect

PON & interconnect

Passive Optical Network design and deployment for fixed broadband operators, combined with peering and interconnect strategy for service providers managing complex traffic exchange relationships.
Who we work with

Built for the most demanding network environments

icon Service providers & ISPs

Service providers & ISPs

National and regional ISPs, wholesale providers, and internet exchange operators — environments where routing table scale, subscriber management, and uptime are existential requirements.
icon Datacenters & hosting

Datacenters & hosting

Colocation facilities, cloud infrastructure providers, and managed hosting operators — where physical density, power efficiency, and multi-tenant network isolation define operational success.
icon Telcos & carriers

Telcos & carriers

Fixed and mobile network operators managing national infrastructure — from access networks and metro aggregation through to core IP/MPLS backbone design and operations.
How we engage

Three service lines built for operators

The same disciplines — applied at the scale and rigour that mission-critical network environments demand.

Professional services

End-to-end network deployment, integration, and migration — from lab validation and staging through to production rollout and knowledge transfer. Delivered by engineers who have done it before, at scale.

Managed services

24/7 network monitoring, operations, and engineering support — giving service providers and datacenter operators expert capacity without the overhead of building and retaining it entirely in-house.

Consulting services

Network architecture, technology strategy, and vendor-neutral design. We help service providers and telcos make the right engineering decisions — at the right time, for the right reasons.

Why Nomios

What operators tell us sets us apart

Engineers who have run service provider networks

Our team includes engineers who have designed and operated national-scale ISP and carrier networks. We understand the operational constraints, the scaling challenges, and the uptime expectations that are unique to this environment.

Carrier-grade, not enterprise-grade

Service provider networks operate at different scale, complexity, and availability requirements than enterprise environments. We design and deploy for that reality — not a scaled-up version of something built for a different use case.

Vendor depth, not just breadth

We hold the highest certification levels with Cisco, Juniper, Nokia, and Arista — not just reseller relationships. That engineering depth means faster problem resolution and better design decisions.

Two decades of European SP heritage

We have been building and operating mission-critical networks in Europe since before cloud was a word. That long-term relationships and operational track record is something no newer entrant can replicate.
