Network as a Service (NaaS)

What This Service Addresses

Maintaining a network well is not a one-time activity. Configuration drifts. Equipment ages. Traffic patterns change. Vulnerabilities emerge that require assessment and remediation. Incidents occur that require structured response. And the cumulative effect of small, unreviewed changes creates the kind of infrastructure complexity that eventually produces outages and security failures.

NaaS from FM-NetSec Nordic is an ongoing managed network service arrangement covering the operational activities that keep network infrastructure stable, secure, and correctly configured over time. It is structured for organisations that need professional-level network operations without the cost or availability constraints of building a specialist internal team.

What the Service Covers

• Network monitoring — continuous monitoring of infrastructure health, availability, and performance metrics, with alerting for anomalies and threshold breaches
• Configuration management — maintaining configuration consistency, reviewing and approving changes, and preventing configuration drift between devices and design intent
• Patch and firmware management — tracking vendor security advisories, assessing applicability, and coordinating controlled patch deployment
• Incident response — priority response to network incidents within defined response time targets, including structured diagnosis and resolution
• Change management — review and implementation of operational changes to the network, with rollback procedures and documentation
• Periodic review — scheduled infrastructure review sessions to assess configuration state, identify emerging risk, and recommend proactive improvements
• Documentation maintenance — keeping network documentation current as changes occur, ensuring operational continuity does not depend on individual knowledge

How NaaS Differs from Break/Fix Support

Most managed support arrangements are reactive — they respond when something breaks. NaaS is fundamentally different: it is designed to prevent problems from occurring and to catch emerging issues before they become incidents.

This distinction matters operationally. In a reactive model, the cost of a failure is the outage itself, plus the cost of emergency response. In a proactive model, most failures are prevented through regular review and controlled change — and when incidents do occur, the response is faster because the infrastructure is well-understood and well-documented.

Who NaaS Is For

This service is most effective for organisations in one of these situations:

• Organisations without internal network specialists — where the IT team handles a broad remit and network infrastructure is managed reactively rather than proactively
• Post-implementation continuity — organisations that have completed a network redesign or implementation and want to maintain the new infrastructure at the same standard it was built
• Compliance continuity — organisations with ongoing DORA, NIS2, or sector-specific obligations that require demonstrable, ongoing network management practices
• Scaling operations — growing organisations where the network is increasing in complexity faster than internal capability to manage it

Service Scope and Customisation

NaaS arrangements are scoped individually to the organisation's environment and requirements. The service scope, response time targets, reporting frequency, and included activities are defined in a service agreement at the start of the arrangement. Scope can be adjusted as the organisation's needs change.

"The most expensive network management approach is one that only responds when something breaks. Proactive operations prevent most failures from occurring in the first place."
