Modern Networking for the NHS: Security, Resilience and Reliability

Arista Networks is an industry leader in modern, data-driven networking for always-on, critical environments. Utilising advanced networking solutions means NHS Trusts can reliably and easily access major digital investments such as Electronic Patient Records (EPR), ERP, RTLS, imaging platforms, and cloud services. 

Resilient, high-performance networking is critical to clinical safety and operational continuity. Arista’s open, standards-based designs combined with the highest performance hardware removes legacy bottlenecks that deliver predictable performance and real-time visibility across the hospital estate. For ease of use, Arista provides EOS® - a single network operating system - and CloudVision® - a unified management platform across the entire product portfolio. With these, Trusts reduce complexity, streamline network operations, and
achieve lower total cost of ownership by simplifying support models, training requirements, and day-to-day management overheads.

Supporting DSPT and CAF Expectations

Arista helps support NHS Trusts in meeting CAF-aligned Data Security and Protection Toolkit
(DSPT) expectations through secure network design, built-in resilience, and continuous
operational visibility. A single, consistent operating system across all platforms (EOS) helps
simplify patching, change control, and the production of audit evidence, supporting
assurance and governance activities.

Zero-Downtime Operations and Anytime Patching

With Smart System Upgrades and continuous PoE, Arista enables zero-downtime software upgrades, avoiding extended reboot times and service interruptions for patient-critical systems. Security patches can be applied at any time, removing the need for disruptive maintenance windows, and eliminating outages, while supporting ongoing service availability.

Maximising the Value of EPR Investments

Arista’s scalable spine-and-leaf architecture delivers high bandwidth, consistent latency, high availability, and linear growth, ensures fast, reliable access to EPR systems across wards, clinics, and data centres. This modern network foundation empowers NHS organisations to fully realise the clinical and operational benefits of EPR and other strategic digital programmes, both now and as requirements evolve.

Secure, Open, and Future-Ready

Integrated security, real-time telemetry, and open APIs support multi-vendor environments without proprietary lock-in. The result is a network that is simpler to operate, easier to evidence for assurance purposes, and adaptable to future healthcare technologies and service models.

Arista is a safe choice for critical networks, providing a stable, resilient foundation for the digital services that NHS organisations depend on every day.

Meet Amy Allen and Mike Furby at HETT stand 55 to discuss real-world examples of this modern network infrastructure.

Arista Networks will demonstrate how modern networking enables NHS Trusts to maximise the value of their EPR systems and critical digital investments, at HETT 2025, stand A55. By providing deeper visibility and telemetry across the network, Arista enables healthcare organisations to build resilient, high-performance infrastructure that supports both clinical and operational demands
