No. 1 · Score 95.6
Cato Networks
Cloud-native SASE / SD-WAN platform · Typical deployment: hours
Single converged platform with no policy or log fragmentation across SD-WAN and security functions.
Watch out: Less suited to best-of-breed buyers wanting Zscaler or Netskope as the SSE layer.
Contact Cato Networks via Netify ↗No. 2 · Score 92.3
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
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 91.7
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 91.4
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 88.9
Aryaka
Managed SD-WAN / SASE provider · Typical deployment: days
Unified SASE delivered as a managed service from end to end, including the private global core network and WAN optimisation.
Watch out: Smaller PoP footprint and partner ecosystem than the hyperscale SASE vendors; coverage must match your geographic profile.
Contact Aryaka via Netify ↗No. 7 · Score 88.5
AT&T Business
Global carrier managed SD-WAN / SASE provider · Typical deployment: months
Major US carrier-led managed SD-WAN portfolio with multi-vendor platform options (including Fortinet for AT&T SASE).

Contact AT&T Business via Netify ↗No. 8 · Score 88
NTT DATA / NTT Ltd.
Global managed network provider · Typical deployment: months
24x7 managed SD-WAN delivery via global operations centres with strong portal visibility.
Watch out: Platform fit depends on which vendor is being proposed (Palo Alto, Zscaler, others); evaluate platform independently.
Contact NTT DATA / NTT Ltd. via Netify ↗No. 9 · Score 87.6
Verizon Business
Global carrier managed SD-WAN / SASE provider · Typical deployment: months
Global carrier-led managed SASE and SD-WAN with strong North American presence and international delivery.

Contact Verizon Business via Netify ↗No. 10 · Score 87.4
BT Business / BT Global
Global/UK managed SD-WAN / SASE provider · Typical deployment: weeks
UK market leader for managed SD-WAN with deep access circuit ownership and field engineering capability.
