Active defense starts in the network

Network Security: Build a Secure Infrastructure

 At a time when threats are industrialized and attackers are using AI, the old “firewall at the door” approach is no longer enough. Modern network security is about converging networking and security into one intelligent solution. Together with Fortinet, Stratu delivers a Security-Driven Networking solution that does more than just move data. It actively analyzes, segments, and protects your business against both known and unknown threats in real time.

Stop threats automatically

We use Fortinet’s AI-driven security to deeply inspect traffic, including encrypted traffic. The system stops ransomware and exploits before they reach your users.

Reduce costs

Replace expensive MPLS connections with Secure SD-WAN. Gain higher bandwidth and improved cloud performance at a fraction of the cost, without compromising security.

NIS2 compliance

Gain full logging and reporting across your entire network. We help ensure you can document segmentation, incident management, and ongoing security-driven maintenance for authorities and compliance audits.

Is your network a bottleneck or a filter?

Most networks were built for a world that no longer exists

Many companies still operate their networks based on principles from 2015: a strong “castle wall” around the headquarters and trust in everything inside it. But today, with data living in the cloud and users working from anywhere, this model creates critical security gaps.

The three biggest risks of traditional network architecture:

  • Lack of Visibility: More than 80% of modern malware hides in encrypted traffic (HTTPS). If your firewall does not have the capacity to inspect this traffic (“SSL Inspection”), you are effectively blind.

  • Internal Threats: Once a hacker gets inside, they can move freely across a “flat” network. Without internal segmentation, a single infected device can compromise the entire server environment.

  • Complex Administration: Managing Wi-Fi, switches, and firewalls across three different systems is time-consuming and often leads to manual errors, which remain one of the most common causes of security breaches.

We aim to be our customers’ best decision

We are proud to work with

Fortinet Security Fabric

One platform, one operating system, total control

At Stratu, we believe in convergence. We build your network on a foundation of Fortinet Security Fabric, where every device, from the firewall in the data center to the access point in the ceiling, speaks the same language (FortiOS).

This enables us to deliver Active Defense:

  1. AI-Driven Protection: Our solutions leverage live data from millions of sensors globally. If a new threat is detected in Japan at 9:00 AM, your network in Denmark is protected by 9:01 AM.

  2. LAN Edge Integration: Security does not stop at the cable. If a PC behaves suspiciously, the firewall can instruct the switch to automatically shut down the port and isolate the device.

  3. Unified Management: We manage your entire security environment from one centralized dashboard. This ensures consistent policies, whether users are working from headquarters or from home.

How We Get Started

A Secure Transition Without Downtime

Replacing the core of your company’s infrastructure can seem overwhelming. But with Stratu, we follow a proven process that ensures a smooth transition.

1. Analysis & Design (1–2 weeks) We do not start by selling hardware. We start by analyzing your traffic. Which applications are you using? Where are the bottlenecks? We design an architecture that fits your business needs and NIS2 requirements.

2. Configuration & Testing (2–3 weeks) We prepare and configure all equipment in our own environment first. Policies, segmentation, and SD-WAN rules are set up in advance, making the devices essentially “plug and play” when they arrive at your site.

3. Deployment & Operations (Weekend/Evening) The actual transition is typically scheduled outside working hours to minimize disruption. With Fortinet’s “Zero Touch Deployment,” we can often roll out solutions to branch offices without requiring a technician on-site. From day one, your environment is covered by our monitoring and operations services.

Modernizing Network Technology

Secure SD-WAN: Reduce Costs and Improve Application Performance

Traditional network connections (MPLS) are expensive, slow to deploy, and poorly suited for cloud traffic. With Secure SD-WAN we modernize the way your locations connect.

Why Switch to SD-WAN with Stratu?

  • Better User Experience: The network recognizes more than 5,000 applications (e.g. Teams, Office 365, Salesforce). It automatically prioritizes business-critical traffic, ensuring video meetings remain stable even when colleagues are downloading large files.

  • Direct-to-Cloud Connectivity: We route traffic securely and directly to the internet from branch offices, instead of forcing everything through a bottleneck at headquarters.

  • Built-In Security: Unlike many other SD-WAN solutions, Fortinet’s Secure SD-WAN is built with an integrated Next-Generation Firewall. This reduces the need for additional hardware and licenses.

The Best of Both Worlds

Network Security (FAQ)

In 9 out of 10 cases, yes. SD-WAN provides the same stability and security, but with far greater flexibility and at a lower cost, because we can use standard internet connections more intelligently.

With Fortinet’s technology, we can extend security all the way to the home office (“Zero Trust Network Access”). This means employees have the same level of protection and access at home as they do in the office - without the need for a cumbersome VPN.

Fortinet’s platform has built-in logging and reporting that directly supports NIS2 requirements (Article 21) for incident handling and network security. We centrally manage patching and maintenance. We can generate the reports auditors request with just a few clicks.

Column in Ingeniøren

With countless emails and passwords, cyber fatigue is taking hold

In a column in Ingeniøren, our CEO Jeppe Klestrup shares his thoughts on a growing challenge: cyber fatigue.

In the article, he writes:

"Cyber fatigue is a form of mental exhaustion that affects two levels. On one side are employees who face a constant stream of warnings, passwords and security requirements.

 The result is not greater vigilance, but that people tune out and ignore warnings simply to get through the working day.

On the other side are decision-makers, including IT managers tired of constantly having to choose between security, operations and budgets."

Network Security FAQ

Hvad er Network Security?
Network Security omfatter de teknologier og sikkerhedsforanstaltninger, der beskytter virksomhedens netværk og den trafik, der bevæger sig igennem det. Moderne netværkssikkerhed handler blandt andet om firewall, trafikinspektion, segmentering, sikker adgang, overvågning og beskyttelse af både lokale og cloudbaserede ressourcer.
 
Stratu bygger sin Network Security-løsning på Fortinet Security Fabric.
 
Virksomheder anvender i stigende grad cloudtjenester, hybride arbejdsmiljøer og mange forskellige lokationer. Samtidig kan trusler gemme sig i krypteret trafik eller bevæge sig internt i netværket, hvis først en enhed er kompromitteret.
 
Derfor kombinerer moderne Network Security firewall-funktionalitet med blandt andet trafikinspektion, segmentering og central administration.
Secure SD-WAN kombinerer intelligent styring af netværkstrafikken mellem virksomhedens lokationer med integreret sikkerhed. Trafikken kan automatisk sendes via den mest optimale forbindelse, samtidig med at sikkerhedspolitikker håndhæves.
 
Stratus løsning anvender Fortinets Secure SD-WAN, hvor Next-Generation Firewall er integreret i platformen.
I mange virksomheder kan Secure SD-WAN helt eller delvist erstatte traditionelle MPLS-forbindelser. Det kan give større fleksibilitet og gøre det muligt at anvende almindelige internetforbindelser mere intelligent, samtidig med at virksomhedens sikkerhedspolitikker fastholdes.
 
Stratu vurderer på den eksisterende netværksarkitektur og virksomhedens krav, før den konkrete løsning designes.
Netværkssegmentering betyder, at virksomhedens netværk opdeles i adskilte områder med forskellige adgangsregler. Hvis en computer eller bruger bliver kompromitteret, kan segmentering begrænse angriberens mulighed for frit at bevæge sig videre til andre systemer og servere.
 
Stratu fremhæver segmentering som et centralt element i moderne Network Security.
Sikkerheden kan udvides ud over virksomhedens fysiske kontorer gennem teknologier som Zero Trust Network Access. Det gør det muligt at kontrollere og sikre medarbejdernes adgang til virksomhedens ressourcer, uanset hvorfra de arbejder.
Ja. Network Security kan understøtte flere af de tekniske sikkerhedsforanstaltninger, der er relevante i forbindelse med NIS2. Fortinet-platformen tilbyder blandt andet logging, rapportering og central styring, som kan understøtte arbejdet med netværkssikkerhed, segmentering og hændelseshåndtering. Det vil eksempelvist være et krav i forhold til NIS2 at netværksopsætningen er dokumenteret og beskyttet, og at udstyret er vedligeholdt med rette software. Særligt i en tid hvor hastigheden hvormed nye sårbarheder stiger voldsomt vil være det vigtigt at have løbende patchninger og backup af alt, der kan sættes strøm til.
