How NaaS reliability and resilience shifts network risk in 2023
3/3/23, 2:30 pm
The rise of Network as a Service (NaaS) is driven by a need for scalable networks without the burden of infrastructure ownership.
Why is this next generation of ‘as a Service’ creating such a stir? Because alongside the compelling operational benefits of a flexible, cost-effective and innovative solution, NaaS is emerging as a powerful risk management tool that provides network reliability and resilience.
How the NaaS model works
The Network-as-a-Service (NaaS) model refers to the delivery of networking functionality and capabilities as a service, rather than as a product. In this model, customers can access and use network resources and services, without having to invest in and manage their own physical infrastructure. This replaces the previously hardware-centric and capital-intensive approach to building and managing networks.
The NaaS model typically uses a cloud-based or on-prem management platform – accessed and controlled by providers and/or customers through web-based interfaces or APIs. The provider manages and maintains the underlying physical infrastructure tailored to the customer's specific business needs.
Customers can choose from a variety of network services, such as software-defined networks for LAN, Wi-Fi, SD-WAN, SASE/SSE, load balancers, firewalls and can specify desired performance, security, and availability.
One of the key benefits of the NaaS model is the ability to scale your network without investing in and managing additional hardware. NaaS can also provide more cost-effective and flexible alternatives to traditional networking solutions. For new businesses, it eliminates a sizable portion of the upfront capital investment. For those businesses looking to trim or refocus their IT resources, it reduces the need for operational inhouse staff to put the focus on strategic support.
How NaaS is different from traditional managed network services
Flexibility for growth
Organisations using NaaS access and use resources without owning the infrastructure, allowing for simpler scaling and a more flexible and cost-effective solution.
NaaS typically operates on a pay-as-you-go basis rather than requiring a large upfront investment, and businesses can avoid infrastructure costs.
Updates delivered at speed
Businesses access the latest technology and services without infrastructure upgrades, providing an edge on getting innovation to market.
Focus on core activities
NaaS models get network specialists back to core challenges rather than ongoing infrastructure management and maintenance.
NaaS providers typically have specialised security expertise above and beyond what most organisations can access.
What’s holding you back from NaaS?
While the benefits of NaaS are compelling, common concerns include:
- Clear accountability for SLA with the integrator providing NaaS
- Reliability of network uptime
- Loss of in-house visibility and control
- Compliance with internal procurement and external regulations
- Data sovereignty and security
The thread that ties the above concerns together is risk – the risk of downtime, disruption, data breaches, and compliance failures. The beauty of NaaS? You no longer own the risk.
NaaS as a risk management tool
When you outsource your network, you outsource the associated risks. Your network effectively becomes a utility, like electricity, water or gas, that you pay for by subscription. Like utility providers, your service provider is responsible for delivering the infrastructure, services and maintenance – including risk management and mitigation. It’s up to your provider to:
- Keep the network running 24/7
- Monitor the network continuously
- Identify, escalate and resolve issues fast to meet the specified SLAs
With tighter integration between the network and network security, NaaS by its very nature delivers enhanced protection. While some providers take a piecemeal approach to network security, NaaS typically incorporates all network services such as software-defined networks for LAN, Wi-Fi, SD-WAN, SASE/SSE, load balancers, firewalls etc.

How SDN underpins your NaaS
Today's increasingly dynamic networks have led to piecemeal security solutions patched together across multiple vendors. Unfortunately, patches inevitably lead to network vulnerabilities.
Today’s networks need security solutions similarly designed to scale and adapt. An essential guiding principle is Security-Driven Networking (SDN) which weaves together an organisation’s network infrastructure and security architecture, enabling the network to scale without compromising security.
“SDN mitigates increasing security threats and an expanding attack surface by putting security front and centre of network development and deployment. With security embedded in the infrastructure, networks can evolve and expand freely.”
