Ranked shortlist · Updated June 2026
Best SD-WAN and SASE providers for the UK public sector (2026)
Ranked shortlist of SD-WAN and SASE providers for UK public sector buyers: NHS trusts and integrated care systems, central and local government, and public bodies. Providers must show public evidence of government sector capability and confirmed UK and Ireland coverage; each is then scored against the Netify 40-feature evaluation matrix. Typical drivers include UK data residency and sovereignty, UK-based support and monitoring, certified security, procurement through established frameworks, and migration off legacy MPLS or, for NHS bodies, planning around HSCN transition. Grades are indicative desk research; confirm via RFP.
Netify's June 2026 evaluation ranks: 1. Cato Networks (96.2); 2. BT Business / BT Global (95.1); 3. Verizon Business (95.1); 4. NTT DATA / NTT Ltd. (92.9); 5. Orange Business (92.9); 6. Telefónica Tech (92.9); 7. Colt Technology Services (91.8); 8. Vodafone Business (91.1); 9. Palo Alto Networks (90.9); 10. Aryaka (90.8).

Questions
About this ranking
Which SD-WAN and SASE providers are best for the UK public sector?
The ranking above lists providers with public evidence of government sector capability and confirmed UK and Ireland coverage, ordered by weighted score across the Netify 40-feature matrix. Sector and regional evidence are gating requirements, not tie-breakers: providers without both are excluded.
SASE or SD-WAN: what is right for the NHS?
They solve different halves of the same problem. SD-WAN replaces or augments legacy WAN connectivity across hospital, clinic and administrative sites, which matters during HSCN transition and MPLS contract end. SASE adds cloud-delivered security, zero trust network access, secure web gateway and related controls, for clinical and hybrid staff working from any location. Many NHS bodies phase SD-WAN first and add the security service edge after, or procure both together as a managed SASE service. The practical answer is to state both scopes in the requirement so suppliers price the journey rather than a single endpoint.
How do UK public sector bodies usually procure SD-WAN and SASE?
Most buy through established public procurement frameworks or run a further competition, evaluating structured supplier responses against published criteria. A clear requirements document is the common thread: it defines scope, sites, compliance needs, evaluation weighting and evidence requests. The Netify RFP Builder generates one from a guided set of questions, and the output can be used inside a framework competition or a direct procurement.
Do these providers offer UK data residency and UK-based support?
Every provider in this ranking has confirmed UK and Ireland coverage, but residency commitments, UK points of presence and the location of monitoring and support teams vary by provider and by service tier. Treat each as an evidence item: ask for contractual data residency options, named NOC and SOC locations and UK support hours in the supplier response, rather than relying on marketing statements.
