No. 1 · Score 93.5
Cato Networks
Cloud-native SASE / SD-WAN platform · Typical deployment: hours
Cato's SASE solution enables network and security policy to be run through the same engine, allowing a single policy framework across both (rather than two separately managed systems like other vendors on the market). With integrated ZTNA, cloud-native segmentation and centralised policy controls, Cato lets agencies isolate the likes of citizen services, departmental applications and operational workloads across a shared fabric without the complexity of coordinating between separate products.
For agencies migrating away from MPLS-dependent architectures, the convergence means the security stack migrates with the network rather than needing to be re-architected separately.
Evidence caveats: Government and public sector: Partial
Watch out: public sector organisations with established multi-vendor procurement frameworks, or those under sovereign cloud mandates, need to validate data residency options and local processing requirements before standardising on Cato. The all-in-one architecture that simplifies operations in a commercial setting can conflict with procurement rules that require supplier diversity or approved product lists in government contexts.

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. 3 · Score 92.1
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. 4 · Score 91.8
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. 5 · Score 90.2
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.
Evidence caveats: Government and public sector: Partial
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. 6 · Score 89
AT&T Business
Global carrier managed SD-WAN / SASE provider · Typical deployment: months
AT&T's multi-vendor platform options, including Fortinet for AT&T SASE, give government agencies flexibility in how they approach Zero Trust adoption whilst still maintaining interoperability with existing public sector environments.
Watch out: the underlying platform varies by service tier, and differences in platform capability affect sovereign hosting options, compliance reporting, cryptographic segmentation and Zero Trust functionality. Government buyers working within fixed budget cycles and public procurement rules should confirm which platform is actually proposed for their scope (and what that means for those specific compliance requirements) before the contract stage.
Contact AT&T Business via Netify ↗No. 7 · Score 88.6
NTT DATA / NTT Ltd.
Global managed network provider · Typical deployment: months
NTT's 24x7 global operations centres and support for multiple leading security platforms make it well suited to large government organisations that need to align networking and security architectures with evolving Zero Trust mandates without standardising on a single vendor platform. Comprehensive monitoring and reporting capabilities support audit readiness and regulatory compliance - the portal visibility gives central teams the evidence trail that compliance programmes need without having to request it from the provider each time.
Watch out: NTT doesn't build its own platform, and compliance capabilities, sovereign cloud support, segmentation functionality and Zero Trust maturity vary between the platforms it wraps managed service around. Each platform needs assessing against the agency's long-term security architecture standards and regulatory obligations separately from NTT's overall managed service score.
Contact NTT DATA / NTT Ltd. via Netify ↗No. 8 · Score 88.2
Verizon Business
Global carrier managed SD-WAN / SASE provider · Typical deployment: months
Verizon's carrier-scale infrastructure and managed security portfolio support government organisations modernising their wide area networks while keeping strict governance controls in place. Integrated SASE and Zero Trust capabilities enforce identity-based access across remote employees, branch offices and field operations - the architecture suits agencies that can't afford a hard cutover from legacy systems and need to run hybrid WAN environments through a transition period.
Watch out: the platform is largely Versa-based and agencies should validate sovereign hosting capabilities, regional compliance support and local regulatory alignment for their specific jurisdiction before deployment. Platform standardisation on Versa also affects flexibility when government security mandates evolve, so that's worth factoring into long-term architecture planning rather than treating as a fixed point.
Contact Verizon Business via Netify ↗No. 9 · Score 88
BT Business / BT Global
Global/UK managed SD-WAN / SASE provider · Typical deployment: weeks
BT's presence across public sector procurement frameworks, combined with deep access circuit ownership and field engineering capability, puts it in a strong position for large-scale UK government transformation programmes. The operational model supports hybrid WAN migration from legacy MPLS estates while keeping critical citizen-facing applications running throughout - BT managing the underlay and overlay together removes the coordination risk that comes when those are owned by different suppliers.
Managed segmentation and security controls support the isolation of departments, operational systems and shared services as agencies work toward mandated Zero Trust operating models.
Watch out: As BT's SD-WAN portfolio isn't built on one platform, the platform choice can have a potential knock-on affect for sovereign data requirements, compliance obligations and long-term architecture standards. Public sector buyers should confirm which platform is being proposed and get a clear answer on how it addresses those specific obligations - not just that BT has a compliant offering in general.
Contact BT Business / BT Global via Netify ↗No. 10 · Score 87.9
Cisco
SD-WAN / SASE technology vendor · Typical deployment: weeks
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.
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.
