Arista VeloCloud — 9.2
Arista VeloCloud operates a global cloud network with more than 700 gateways across over 200 PoPs worldwide. Uses public cloud gateways with dynamic multipath optimisation (DMPO) across multiple ISPs. Three components: SD-WAN Orchestrator (SaaS management), SD-WAN Gateways (global PoPs), and SD-WAN Edge (on-premises appliances). Service model supports DIY orchestration or fully managed via partners (Lumen, BT, Virgin).
Best for: Large enterprises requiring multi-cloud optimisation.
Key feature: More than 700 gateways across 200+ PoPs with DMPO. Patented per-packet path quality monitoring providing MPLS-like quality of service over broadband internet through forward error correction and packet duplication.
Drawback: Greater management complexity than simpler solutions such as Meraki; requires expertise to leverage full capabilities.
Reference client: Teradyne — reduced global latency by 40% transitioning global infrastructure to VeloCloud (formerly VMware) to support AI-driven workloads.
Cato Networks — 9.2
Pioneer of cloud-native SASE, providing both SD-WAN and security services via their global cloud platform and small edge devices (sockets) rather than large-scale appliances. Every Cato PoP includes a full security stack covering NGFW, SWG, CASB, DLP and ZTNA, with single-pass architecture processing all security functions simultaneously. Over 85 global PoPs.
Best for: Cloud-first businesses wanting maximum simplicity and predictable costs, particularly SMEs without dedicated networking teams.
Key feature: Cloud-native SASE with single-pass architecture — all security processing (NGFW, SWG, CASB, DLP, ZTNA) happens once at nearest PoP, no backhauling required. London and Manchester PoPs secure UK traffic locally before routing globally. First SASE platform to achieve PCI DSS v4.0 compliance.
Drawback: Cloud-only dependency means no on-premises processing option; limited networking flexibility compared to traditional overlay solutions.
Reference client: Grant & Stone (UK builders merchant) — replaced legacy MPLS/Ethernet with dual broadband/4G via Cato Sockets, identifying Windows update bandwidth issues through Cato visibility.
Cisco Catalyst — 9.6
Cisco’s enterprise-grade SD-WAN with vManage orchestration, advanced segmentation and complex routing protocols (OSPF, BGP, EIGRP). Result of the 2017 Viptela acquisition. Purpose-built architecture separating control, data and management planes. Cloud-hosted or on-premises vManage deployment options. Integrates with Cisco Umbrella, Duo and Secure Access.
Best for: Large enterprises (Fortune 500) with complex routing requirements and existing Cisco infrastructure.
Key feature: vManage unified orchestration with separated data/control planes. Over 20,000 SD-WAN customers including 70% of Fortune 100. Leader in Gartner Magic Quadrant for SD-WAN for sixth consecutive year.
Drawback: Significantly higher complexity than cloud-native alternatives; requires specialist Cisco expertise. Total cost of ownership typically 20-30% higher than cloud-native alternatives.
Reference client: Calderdale and Huddersfield NHS Trust — Cisco DNA Centre and Firewall Management Centre for medical device tracking, IoT pharmacy monitoring and secure GovRoam.
Cisco Meraki — 8.6
Cisco’s cloud-managed platform that heavily prioritises ease over features. AutoVPN establishes site-to-site connectivity without manual configuration; traffic shaping uses intuitive slider controls. Integrated firewall, content filtering and malware protection. Connects to Umbrella and Cisco Secure Access for extended protection.
Best for: Retail, hospitality, distributed SMEs with limited IT expertise. Default choice for organisations prioritising ease of use.
Key feature: Cloud-managed dashboard with AutoVPN — slider-based QoS allowing junior staff to manage complex networks without CLI expertise. Hundreds of locations deployable within hours.
Drawback: Limited advanced networking capabilities for complex routing scenarios; cloud-only architecture creates dependency on internet connectivity. No OSPF, BGP or EIGRP support.
Reference client: Pret A Manger (UK) — rapid integration of 35 new sites in 12 months following the EAT acquisition.
Fortinet — 9.6
Security-focused vendor offering DIY/overlay SD-WAN via FortiGate hardware appliances with purpose-built ASIC security processors for hardware-accelerated deep packet inspection at 10+ Gbps without performance degradation. Many UK MSPs (including BT Business and Virgin Media O2) embed FortiGate into their managed services. FortiSASE extends ZTNA and CASB for remote workers.
Best for: Organisations with sensitive data, secure connectivity, or in-depth security monitoring requirements requiring on-premises processing — particularly NHS trusts and financial institutions.
Key feature: Purpose-built ASIC security processors — hardware-accelerated deep packet inspection at 10 Gbps without performance degradation. Serves over 700,000 enterprises worldwide. Holds UK Government G-Cloud 14 framework approval and ISO/IEC 27001 compliance.
Drawback: Requires customer-provided connectivity (no owned backbone); steeper learning curve than cloud-managed solutions. FortiGate appliances £2,000-£15,000 per device depending on throughput.
Reference client: Routes Healthcare (UK) — exceeded NHS Digital DSPT standards. Private network supporting 1,000+ staff across 18 service centres using ZTNA for mobile workers visiting patients’ homes.
HPE Juniper Networking — 9.5
Following the 2025 merger ($14bn acquisition completed 2 July 2025), HPE Juniper Networking integrates HPE Aruba’s EdgeConnect WAN optimisation with Juniper’s Mist AI and Session Smart Routing (SSR). EdgeConnect provides First-Packet iQ; Juniper SSR provides tunnel-free, session-based routing. Unified under the Mist AI-driven orchestration platform with the Marvis Virtual Network Assistant (VNA).
Best for: Enterprises requiring a combination of AI-driven predictive operations and sub-millisecond application optimisation.
Key feature: Mist AI with First-Packet iQ — the industry’s first AI-native SD-WAN combining Marvis’s conversational troubleshooting with the ability to identify and optimise applications from packet one. Tunnel-free Secure Vector Routing eliminates bandwidth consumption from tunnel encapsulation.
Drawback: Integration of the two legacy platforms into a single management interface is difficult for complex configurations; steeper learning curve for Session Smart Routing. TCO 20-30% higher than cloud-native alternatives.
Reference client: Aston Martin (UK) — consistent, agile network across head office in Gaydon and manufacturing sites for design & production.
Palo Alto Networks — 9.4
Prisma SD-WAN (formerly CloudGenix) is one of the more security-first solutions on the market. Service model supports DIY via Prisma Access or fully managed through partners (e.g. Orange Business Services). Prisma uses Instant-On Network (ION) edge devices connecting to a cloud security platform for native SASE convergence — combining SD-WAN with SSE capabilities (SWG, CASB, ZTNA, DLP).
Best for: Security-conscious enterprises (financial services, healthcare) requiring granular application-based policy control and Layer 7 visibility.
Key feature: Layer 7 application visibility and control — unmatched granular policy control based on applications rather than just ports/protocols, with ML-powered threat prevention. One of only three vendors recognised as a Leader across all three SASE-related Gartner Magic Quadrants (SSE, Single-Vendor SASE, SD-WAN).
Drawback: No owned backbone — overlay architecture only; complex deployment requiring security expertise. UK enterprises report total costs 25-35% higher than mid-market alternatives.
Reference client: Auto Trader UK — 95% reduction in branch deployment time, replacing legacy MPLS with broadband at 99.99% uptime.
Versa Networks — 8.6
