Network Doctor
Check your networks vitals with a free Network Doctor assessment from Node4
See the real health of your network before it becomes a problem
Networks sit at the centre of every business, but complexity, ageing components and hidden misconfigurations can create risk long before symptoms appear.
Network Doctor is a structured diagnostic that assesses the resilience, performance and security of your network, uncovering the issues that jeopardise uptime, productivity and customer experience.
Through a focused review of your network’s “vital signs,” we show you what’s working, what isn’t, and what needs to change, giving you a clear, actionable plan to strengthen performance and minimise the risk of costly outages.

Evaluate your network’s “vital signs” across resilience, performance, configuration and cost
Challenges we solve
From hybrid work and cloud applications to evolving security threats, network demands have never been greater. Yet many businesses rely on infrastructure that has grown organically over years, creating blind spots, inconsistent performance and hidden vulnerabilities.
Most teams only discover issues after an outage, slowdown or security alert. Without a holistic understanding of network health, operational resilience becomes guesswork.
Key challenges
- Fragmented or ageing infrastructure increasing risk of downtime
- Limited visibility into network performance, resilience and configuration
- Rising security concerns across distributed edges and hybrid workforces
- Costs rising from under‑used circuits, duplicated services or inefficient design
- Inability to scale or support new digital initiatives without disruption
