No. 1 · Score 95.8
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
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 89.3
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. 4 · Score 88.9
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).
Watch out: Underlying platform varies by service tier; buyers should confirm which platform supports the proposed scope.
Contact AT&T Business via Netify ↗No. 5 · Score 88.1
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.
Watch out: Platform is largely Versa-based; buyers wanting platform optionality should evaluate alternatives.
Contact Verizon Business via Netify ↗No. 6 · Score 87.7
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.
Contact Cisco via Netify ↗No. 7 · Score 87.1
Lumen
Managed SD-WAN / NaaS provider · Typical deployment: months
Fully managed or co-managed SD-WAN with strong NaaS positioning and integrated network services.
Watch out: SASE and security capabilities are largely partner-integrated rather than native; the SSE platform choice needs explicit evaluation.
Contact Lumen via Netify ↗No. 8 · Score 86.9
Colt Technology Services
Enterprise managed SD-WAN / connectivity provider · Typical deployment: months
SD-WAN and SASE with strong European data sovereignty positioning.
Watch out: Global delivery depth outside Europe is less prominent than the largest global carriers.
Contact Colt Technology Services via Netify ↗No. 9 · Score 86.6
NTT DATA / NTT Ltd.
Global managed network provider · Typical deployment: months
24x7 managed SD-WAN delivery via global operations centres with strong portal visibility.
Evidence caveats: Mid-market: Partial
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. 10 · Score 86.5
Comcast Business / Masergy
Managed SD-WAN / SASE provider · Typical deployment: weeks
SASE combining SD-WAN and security available fully managed or co-managed, drawing on Masergy AIOps heritage.
