Executive Summary

Arista Networks attributes its recognition as a Leader in The Forrester Wave™: Data Center Network Solutions, Q3 2026 to its evolution from a data center specialist into a broader enterprise networking provider across campus and WAN, accelerated by its VeloCloud SD-WAN acquisition. Arista Networks is an industry leader in data-driven, client to cloud networking for large data center/AI, campus and routing environments. Arista’s award-winning platforms deliver availability, agility, automation, analytics and security through an advanced network operating stack.

Arista's Key Highlights:

• Strategy. Arista has become a Leader in AI fabrics and enterprise networking, driven by high speed AI infrastructure innovation and strong customer and partner engagement. Its high-quality support and services reinforce enterprise adoption and operational confidence along with its superior pricing flexibility and transparency. Arista demonstrates a consistent vision and roadmap centered on a unified OS and platform strategy that’s designed to reduce operational complexity, minimize product sprawl, and support both traditional and AI-driven data centers. However, its competitive advantage has narrowed as competitors have increasingly embraced a similar vision, resulting in an on-par score.
• Capabilities. Arista’s differentiation lies in EOS, a consistent, modular network OS across its portfolio that enables unified automation, policy consistency, and streaming telemetry from data center to branch. Arista stands out for its management types, switch portfolio, administrative experience, design support, segmentation, Zero Trust security, declarative transformation, and scalability across data center, campus, WAN, and cloud environments. Its unified telemetry and data model enable end-to-end flow visibility, application-aware analytics, and AI-driven root cause analysis, making it one of the most mature platforms for operational consistency and cross-domain insight without major gaps.
• Customer feedback. Customers praise Arista’s simplicity, automation, and reliability but cite supply chain delays that can slow deployments.
• Forrester’s take. Enterprises looking for a well-integrated and consistent set of networking services across the business in a single console should shortlist Arista Networks.
