No. 1 · Score 95.8
Cato Networks
Cloud-native SASE / SD-WAN platform · Typical deployment: hours
Cato's platform is ideal for large global enterprises needing consistent policy enforcement across a distributed estate, owing to their single converged architecture that runs SD-WAN and security through the same engine - unlike multi-product approaches where policy fragmentation between networking and security layers tends to grow in proportion with the number of sites.
As part of this, Cato's Zero Trust capabilities mean that a new regional office, a newly acquired business or a temporary project site can be brought onto the same policy as the rest of the estate quickly, meanwhile the likes of centralised policy management and cloud-native segmentation mean there's no separate security deployment needed at each location.
Watch out: We would recommend that large enterprises with established best-of-breed security stacks assess consolidation requirements carefully before committing - Cato will conflict with already-invested SSE components (such as Zscaler or Netskope), requiring a significant overhaul in network and security operations rather than a simple addition. For organisations where that security investment is already embedded in compliance frameworks, that's a bigger undertaking than the deployment-in-hours figure suggests.

Versa Networks
SD-WAN / SASE technology vendor · Typical deployment: weeks
Multi-tenancy from the ground up, making Versa a common choice for service providers and carriers building managed SD-WAN and SASE platforms.
Watch out: Less well-known to enterprise buyers as a direct purchase; most enterprise consumption is via service providers.
Contact Versa Networks via Netify ↗No. 3 · Score 92.3
Fortinet
Secure SD-WAN / SASE technology vendor · Typical deployment: days
Native convergence of networking and security on a single operating system (FortiOS) across FortiGate edge, FortiManager and FortiSASE.
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 via Netify ↗No. 4 · Score 92
Palo Alto Networks
SD-WAN / SASE technology vendor · Typical deployment: weeks
Prisma SASE converges SD-WAN, cloud-delivered security, and digital experience management (ADEM) under a single platform identity.
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 via Netify ↗No. 5 · Score 91.7
HPE Aruba Networking
SD-WAN / SSE / branch technology vendor · Typical deployment: days
EdgeConnect SD-WAN (acquired with Silver Peak) is positioned as the foundation for single-vendor SASE alongside Aruba SSE.
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 Networking via Netify ↗No. 6 · Score 89.3
Aryaka
Managed SD-WAN / SASE provider · Typical deployment: days
Aryaka's private global core network is their primary differentiator, unlike other managed vendors on the market that deliver SD-WAN over public internet paths, Aryaka's private backbone provides greater resilience and performance, which is ideal for large global enterprises where application performance across long-haul international routes is a persistent challenge. Meanwhile, WAN optimisation built into that backbone improves responsiveness for cloud and SaaS applications across dispersed global sites, and rapid deployment (days rather than months) suits enterprises running active acquisition programmes.
Watch out: Aryaka's PoP footprint is smaller than the hyperscale SASE vendors, and for a large global enterprise with operations in less-served locations, coverage needs confirming against the actual site list before programme commitment. A gap at a material site is a more significant finding at global enterprise scale than it would be in a smaller deployment.
Contact Aryaka via Netify ↗No. 7 · Score 88.9
AT&T Business
Global carrier managed SD-WAN / SASE provider · Typical deployment: months
We'd argue that AT&T's main differentiator for large global enterprise is the combination of carrier-scale access infrastructure and multi-vendor platform flexibility (including Fortinet for AT&T SASE) - meaning a complex estate with different site types, different regional requirements and different legacy environments doesn't have to be forced into a single architecture.
Watch out: the platform proposed varies by service tier, and capability differences between variants can create inconsistency across a large estate. For a global enterprise where consistent segmentation and security posture is an audit requirement, those differences need confirming platform by platform before deployment - not assumed uniform from the headline proposal.
Contact AT&T Business via Netify ↗No. 8 · Score 88.4
NTT DATA / NTT Ltd.
Global managed network provider · Typical deployment: months
For large global enterprises that need someone actively watching their network at all hours regardless of time zone, NTT's 24x7 global operations centres with follow-the-sun handover are the headline capability. Continuous monitoring and strong portal visibility give central IT teams an accurate picture of performance and security posture (rather than having to assemble that picture from regional reports).
Comprehensive governance and compliance reporting also support the audit readiness requirements that come with operating across multiple regulatory jurisdictions simultaneously.
Watch out: NTT wraps managed service around platforms from the likes of Palo Alto and Zscaler rather than its own stack - meaning security capability, segmentation depth and compliance reporting depend on which platform underlies each regional deployment. Those need assessing independently per region, not assumed consistent from NTT's overall score.
Contact NTT DATA / NTT Ltd. via Netify ↗No. 9 · Score 88.1
Verizon Business
Global carrier managed SD-WAN / SASE provider · Typical deployment: months
Verizon's North American network and carrier-scale managed SASE portfolio make it a strong option for large global enterprises with a significant US presence - the carrier heritage means the infrastructure underneath the managed service has been built for the kind of availability expectations that large enterprise operational teams carry, particularly for always-on North American operations.
Watch out: the platform is largely Versa-based, and for a global enterprise running part of its estate on a different SD-WAN technology, maintaining consistent segmentation policy and audit-ready architecture across both creates reconciliation work for compliance teams. Worth planning for explicitly before rollout rather than leaving as an assumption to resolve during it.
Contact Verizon Business via Netify ↗No. 10 · Score 87.8
BT Business / BT Global
Global/UK managed SD-WAN / SASE provider · Typical deployment: weeks
BT's access circuit ownership is the practical differentiator for large enterprises with significant UK and European footprints - managing the underlay and overlay as a single service removes the coordination overhead between connectivity and managed SD-WAN providers that slows fault resolution and complicates MPLS migration programmes at scale.
As part of this, field engineering capability supports large-scale deployment across distributed sites, meanwhile managed segmentation separates business units, operational systems and shared services under centralised policy.
Watch out: BT's SD-WAN portfolio spans multiple underlying platforms, and for a global enterprise where architecture consistency across every region matters, the question of which platform is being proposed - and whether it's consistent across all geographies - needs answering before contract. Platform variation at scale is genuinely difficult to unwind mid-programme.
