Source evidence
1. Lumen
Best for: Healthcare (partial evidence); both
technology vendor / managed service provider / carrier network provider · Typical deployment: not_confirmed
Fully managed or co-managed SD-WAN with strong NaaS positioning and integrated network services.
Proven capability items: 23 · Verification: 2026-09-01
Watch out: SASE and security capabilities are largely partner-integrated rather than native; the SSE platform choice needs explicit evaluation.
Contact Lumen via Netify ↗Source evidence
2. Versa Networks
Best for: Energy and utilities; Retail and e-commerce (partial evidence); Manufacturing (partial evidence); Small business; platform
technology vendor · Typical deployment: not_confirmed
Multi-tenancy from the ground up, making Versa a common choice for service providers and carriers building managed SD-WAN and SASE platforms.
Proven capability items: 22 · Verification: 2026-09-01
Watch out: Less well-known to enterprise buyers as a direct purchase; most enterprise consumption is via service providers.
Contact Versa Networks via Netify ↗Source evidence
3. Cato Networks
Best for: Retail and e-commerce; Education (partial evidence); Large global enterprise; Mid-market; platform
technology vendor · Typical deployment: not_confirmed
The IT/OT boundary is one of the most pressing issues for the energy and utilities sector, though Cato is well positioned to address this - rather than placing a firewall between two separately managed network layers (like many other solutions on the market), Cato enforces micro-segmentation through one policy engine - control systems, SCADA traffic and enterprise IT coexist on the same WAN fabric, isolated from each other by policy rather than physical separation.
For NERC CIP and NIS2 compliance, centralised policy management and consistent audit logging across distributed substations and generation assets simplifies the evidence-gathering that makes compliance programmes operationally painful at scale.
Proven capability items: 24 · Verification: 2026-09-01
Watch out: utilities running specialised OT security tooling - protocol-aware inspection, industrial monitoring platforms - need to validate integration with Cato's architecture before committing. The single-vendor model assumes a degree of centralised control that not every operational technology environment is structured to give, and discovering that mismatch during rollout rather than before it is an avoidable problem.
Contact Cato Networks via Netify ↗Source evidence
4. Netskope
Best for: Financial services; Professional services; platform
technology vendor · Typical deployment: not_confirmed
Strong CASB heritage; widely recognised as a leading SSE vendor for SaaS-heavy environments.
Proven capability items: 21 · Verification: 2026-09-01
Watch out: Native SD-WAN (Borderless WAN) is newer than dedicated SD-WAN platforms; validate path selection and QoS depth in RFP.
Contact Netskope via Netify ↗Source evidence
5. Palo Alto Networks Prisma SASE
Best for: Retail and e-commerce; Manufacturing; platform
technology vendor · Typical deployment: not_confirmed
Prisma SASE converges SD-WAN, cloud-delivered security, and digital experience management (ADEM) under a single platform identity.
Proven capability items: 21 · Verification: 2026-09-01
Watch out: Premium pricing relative to firewall-led SD-WAN vendors; commercial model requires careful scoping by users, bandwidth, locations and term.
Contact Palo Alto Networks Prisma SASE via Netify ↗Source evidence
6. Cisco
Best for: Manufacturing; Professional services; Hospitality and leisure; Large global enterprise; platform
technology vendor · Typical deployment: not_confirmed
Broadest platform portfolio in the category, covering Catalyst SD-WAN for enterprise WAN, Meraki MX for cloud-managed branch, and Cisco Secure Access for converged SASE delivery.
Proven capability items: 21 · Verification: 2026-09-01
Watch out: Two distinct SD-WAN product lines (Catalyst and Meraki) means buyers should confirm which fits the target deployment profile and the longer-term roadmap.
Contact Cisco via Netify ↗Source evidence
7. Check Point
Best for: Sector evidence not yet reviewed; platform
technology vendor · Typical deployment: not_confirmed
Harmony SASE combines Check Point security heritage with cloud-delivered SASE and optimised SD-WAN performance.
Proven capability items: 17 · Verification: 2026-09-01
Watch out: Dynamic path selection: not confirmed; QoS and traffic shaping: not confirmed; Packet loss remediation: not confirmed. Confirm the exact SD-WAN product and required branch behaviour.
Contact Check Point via Netify ↗Source evidence
8. AT&T Business
Best for: Sector evidence not yet reviewed; Large global enterprise; managed
managed service provider / carrier network provider · Typical deployment: not_confirmed
Substations, solar farms, pipeline monitoring stations and wind generation assets have a connectivity problem that office buildings don't: fixed-line circuits are often unavailable or unreliable, and there's no alternative when the connection drops. AT&T's LTE and 5G network alongside its fixed-line portfolio means resilient communications for those remote assets don't have to depend on a single underlay technology.
Multi-vendor security options, Fortinet for AT&T SASE being one, support Zero Trust segmentation between SCADA environments, operational systems and corporate networks.
Proven capability items: 15 · Verification: 2026-09-01
Watch out: the platform proposed varies by service tier, and OT security capabilities and compliance reporting features differ between them. A utility running legacy substations and modern generation facilities on the same contract may end up with different segmentation models at different sites - in energy environments, that inconsistency carries operational and safety implications that aren't present in a typical enterprise rollout. Pin down the platform per site early.
Contact AT&T Business via Netify ↗Source evidence
9. Aryaka
Best for: Manufacturing; Transport and logistics (partial evidence); both
technology vendor · Typical deployment: not_confirmed
Aryaka's private global core network is the architectural differentiator here. Rather than running across public internet paths, the underlay is Aryaka's own backbone, which gives it a different resilience profile from most managed SD-WAN providers - relevant for energy operators where a connectivity interruption at an operational site has consequences that go well beyond a delayed email. WAN optimisation built into that backbone keeps telemetry and monitoring applications performing consistently across dispersed assets.
Deployment in days rather than months is also a genuine advantage for utilities bringing new generation assets online quickly or extending coverage to remote field locations on short timelines.
Proven capability items: 16 · Verification: 2026-09-01
Watch out: Aryaka's PoP footprint is smaller than the hyperscale SASE vendors. For a utility with assets in remote or less common locations - offshore facilities, rural generation sites, secondary industrial regions - coverage needs checking against the actual site list. Satellite integration options and local technical assistance for critical infrastructure environments should also be confirmed before deployment, not after.
Contact Aryaka via Netify ↗Source evidence
10. Fortinet FortiSASE
Best for: Healthcare; Transport and logistics; Hospitality and leisure; Education (partial evidence); Large global enterprise; both
technology vendor · Typical deployment: not_confirmed
Native convergence of networking and security on a single operating system (FortiOS) across FortiGate edge, FortiManager and FortiSASE.
Proven capability items: 18 · Verification: 2026-09-01
Watch out: Like Cisco, managed delivery is via partners rather than Fortinet directly; underlay and field operations are not owned by the vendor.
Contact Fortinet FortiSASE via Netify ↗Source evidence
11. Juniper Networks
Best for: Sector evidence not yet reviewed; platform
technology vendor · Typical deployment: not_confirmed
Mist AI delivers WAN Assurance, providing AI-driven monitoring and troubleshooting at the WAN edge that few competitors match.
Proven capability items: 13 · Verification: 2026-09-01
Watch out: Full SASE platform: partial evidence; CASB capability: not confirmed; Data loss prevention: not confirmed. Confirm the networking and SSE products and whether separate contracts or operators are required.
Contact Juniper Networks via Netify ↗Source evidence
12. Orange Business
Best for: Manufacturing; Large global enterprise; managed
carrier network provider / integrator · Typical deployment: not_confirmed
Orange Business has NOC depth and field engineering across Europe and Africa that few managed providers can match at comparable coverage levels. For energy organisations with assets in those regions, the value is local operational teams who understand local conditions - regulatory environments, infrastructure constraints, field access logistics - rather than a remote team managing everything from elsewhere. Getting an engineer to a remote generation facility or transmission asset in a secondary market through a partnership model is a qualitatively different proposition.
Managed segmentation capabilities support the separation of OT from enterprise traffic, and the service model is built for the governance complexity of multinational critical infrastructure estates.
Proven capability items: 16 · Verification: 2026-09-01
Watch out: the platform Orange deploys depends on the vendor selected, and OT security capability - protocol awareness, industrial threat detection, compliance reporting - varies across the portfolio. Platform fit for energy environments needs evaluating against what's actually being proposed for each specific site. Orange's overall managed service positioning is not a substitute for that assessment.
Contact Orange Business via Netify ↗Source evidence
13. BT
Best for: Financial services; UK and Ireland; managed
managed service provider / carrier network provider · Typical deployment: not_confirmed
When a connection to a substation or water treatment facility degrades, the speed of fault resolution depends entirely on who owns the access infrastructure. BT's field engineers deal with BT's own circuits - there's no third-party access provider to coordinate with, which shortens the time between a fault being raised and someone actively diagnosing it. For sites running operational systems rather than office applications, that difference matters more than it might look on paper.
BT's NIS2-relevant operational presence across critical national infrastructure also makes it a recognised supplier in regulated energy and utilities procurement in the UK.
Proven capability items: 11 · Verification: 2026-09-01
Watch out: BT's SD-WAN portfolio runs on multiple underlying platforms, and OT protocol visibility, industrial threat detection and compliance reporting capability are not the same across them. The platform proposed for a substation should be evaluated against the OT requirements of that specific environment - it's not interchangeable with what works at a corporate office, even if both are delivered under the same managed service contract.

14. Forcepoint
Best for: Sector evidence not yet reviewed; platform
technology vendor · Typical deployment: not_confirmed
FlexEdge Secure SD-WAN combines secure SD-WAN with strong DLP and data security heritage from the wider Forcepoint portfolio.
Proven capability items: 14 · Verification: 2026-09-01
Watch out: Smaller SD-WAN market presence than the leading platforms.
Contact Forcepoint via Netify ↗Source evidence
15. GTT
Best for: Hospitality and leisure; both
hybrid provider · Typical deployment: not_confirmed
Tier 1 global backbone provides strong international transit capability alongside managed SD-WAN.
Proven capability items: 14 · Verification: 2026-09-01
Watch out: SASE depth depends heavily on the chosen platform partner; native SSE capabilities are not primary positioning.
Contact GTT via Netify ↗Source evidence
16. Zscaler
Best for: Retail and e-commerce; Manufacturing; Energy and utilities; Government and public sector; platform
technology vendor · Typical deployment: not_confirmed
Category leader in SSE with ZIA, ZPA and ZDX; widely adopted as the security layer in best-of-breed SASE architectures.
Proven capability items: 15 · Verification: 2026-09-01
Watch out: Historically SSE-led; native SD-WAN capability is less mature than dedicated SD-WAN platforms (validate path selection, QoS and packet loss in RFP).
Contact Zscaler via Netify ↗Source evidence
17. Colt Technology Services
Best for: Financial services; UK and Ireland; Large global enterprise; managed
carrier network provider · Typical deployment: not_confirmed
European energy operators working to NIS2 obligations will find Colt's data sovereignty positioning more directly applicable than most on this list. Colt controls the physical network path across European business districts, which means demonstrating in-region processing to regulators or auditors doesn't depend on mapping data flows through third-party infrastructure with its own jurisdictional questions. Cloud on-ramp connectivity into European cloud regions is also more direct as a result, useful where operational data needs to reach cloud-based monitoring or analytics platforms without leaving the regulatory perimeter.
Proven capability items: 16 · Verification: 2026-09-01
Watch out: outside Europe, Colt's depth thins considerably relative to the largest global carriers. A utility with assets in North America, the Middle East or Asia has those sites sitting outside Colt's primary operational strength. Local network coverage, cellular backup and field support at those locations need a separate assessment - for a globally distributed energy estate, the European strengths need to be weighed explicitly against what a different provider would offer elsewhere, not assumed to travel.

18. HPE Aruba EdgeConnect
Best for: Healthcare; Financial services; Manufacturing; Professional services; Hospitality and leisure; platform
technology vendor · Typical deployment: not_confirmed
EdgeConnect SD-WAN (acquired with Silver Peak) is positioned as the foundation for single-vendor SASE alongside Aruba SSE.
Proven capability items: 16 · Verification: 2026-09-01
Watch out: Aruba SSE is newer than the SSE leaders (Zscaler, Netskope); buyers wanting best-of-breed SASE should evaluate the SSE capability set carefully.
Contact HPE Aruba EdgeConnect via Netify ↗Source evidence
19. Vodafone Business
Best for: Sector evidence not yet reviewed; UK and Ireland; Large global enterprise; Mid-market; managed
managed service provider / carrier network provider · Typical deployment: not_confirmed
Strong UK and European market presence with NaaS positioning and integrated mobile/fixed access.
Proven capability items: 11 · Verification: 2026-09-01
Watch out: Underlying platform varies by region (VeloCloud in UK, others elsewhere); ensure consistency for multinational deployment.
Contact Vodafone Business via Netify ↗Source evidence
20. NTT DATA
Best for: Retail and e-commerce; Large global enterprise; managed
carrier network provider · Typical deployment: not_confirmed
Large energy organisations with generation, transmission and distribution assets across multiple countries face a governance problem as much as a connectivity one: different regions end up with different security policies, different monitoring standards and different compliance postures, often because they were set up at different times by different teams. NTT's 24x7 global operations centres are oriented toward standardising that picture across the whole estate, with a portal that gives central teams visibility regardless of geography.
For NERC CIP and NIS2 compliance programmes, that centralised audit trail is directly relevant.
Proven capability items: 12 · Verification: 2026-09-01
Watch out: NTT doesn't build its own platform. The managed service wraps around Palo Alto, Zscaler and others, so OT security capability and industrial protocol handling depend entirely on which platform sits underneath a given deployment. NTT's overall score reflects managed service quality - the technology fit for SCADA environments is a separate question that needs answering against the specific platform, not NTT's overall score.
Contact NTT DATA via Netify ↗Source evidence
21. Verizon Business
Best for: Healthcare (partial evidence); Manufacturing (partial evidence); Large global enterprise; managed
managed service provider / carrier network provider · Typical deployment: not_confirmed
Verizon's wireless network is the differentiator for remote site resilience. Substations, field operations centres and renewable generation sites that sit beyond reliable fixed-line coverage can get integrated LTE and 5G backup alongside managed SD-WAN, rather than requiring a separate cellular solution bolted on afterwards. Carrier-grade infrastructure supports availability requirements for critical telemetry and control traffic, and managed SASE adds segmentation between operational systems and enterprise environments.
Proven capability items: 11 · Verification: 2026-09-01
Watch out: the underlying platform is largely Versa-based, and for utilities whose wider estate or OT security tooling is built around a different technology, maintaining consistent segmentation policy across both creates reconciliation work for the operations team. OT change windows in energy environments are infrequent - the integration planning between Versa's IT/OT segmentation model and the existing estate needs to happen well before deployment, not surface during it.

Contact Cloudflare One via Netify ↗Source evidence
25. Comcast Business
Best for: Sector evidence not yet reviewed; managed
managed service provider / carrier network provider · Typical deployment: not_confirmed
Grid telemetry and SCADA communications are more sensitive to latency and packet loss than most enterprise traffic, so the cost of a network problem being discovered after it has already affected those systems is significantly higher than the cost of catching it beforehand. Masergy's AIOps capability (inherited by Comcast Business) is built around that, helping to identify degradation patterns before a connection fails, giving operations teams time to reroute or intervene rather than respond.
The fully managed or co-managed model also suits OT teams whose primary focus is running infrastructure, not managing the network that carries it.
Proven capability items: 8 · Verification: 2026-09-01
Watch out: Comcast's operational depth is North American by origin, and outside that region delivery runs through partners. The monitoring consistency, field support response times and AIOps depth that a North American reference site demonstrates may not carry over to European or Middle Eastern assets delivered through those partnerships - worth asking specifically how the service is structured at each international location, not just whether it's available.

Questions
About this evidence
Which SD-WAN and SASE providers are strongest for energy and utilities?
The leading providers for energy and utilities are listed in the ranking above, each graded on public evidence of sector capability - the likes of case studies, dedicated offerings and certifications - alongside the same 40 technical and service features used across our wider comparison.
How is this energy and utilities ranking calculated?
To ensure the integrity of our rankings, providers without confirmed energy and utilities sector evidence are excluded from this list - with the remainder being scored on a weighted average across 40 capability features (with the same engine powering our interactive shortlist builder, MCP tool and this page to provide reproducible results).
Can I adjust this shortlist for my own requirements?
Yes - the interactive shortlist builder lets you add your operating model, regions, clouds, security features, AI requirements and deployment ceiling on top of the energy and utilities filter. Every configuration is a shareable URL, so you can come back to it or pass it on to colleagues later.
