Arista Networks operates at significant scale in the network and other communications equipment sector, with an Impact500 score of 77.8 and a C grade in the current modeled research cycle. Its strongest modeled pillar is environmental, while future research will continue to test disclosure quality, implementation evidence, and outcomes against sector peers. For companies in this industry, responsible technology, data privacy, cybersecurity, resource-efficient infrastructure, and digital inclusion are central responsibility issues. The opportunities identified in this report are forward-looking practices, not findings of misconduct or evidence that a program is absent. Structural facts retain their source year, and readers should consult the evidence and document sections before using the profile for decisions.
Company overview
Business context and responsibility.
Arista Networks is a large network and other communications equipment organization headquartered in California. Founded in 2004, the company has developed through multiple business and market cycles into an enterprise serving enterprise, public-sector, and consumer digital markets. The organization reports approximately 0 employees and $9.0 billion in annual revenue in the structural dataset used for this profile. Its Fortune rank of 444 is retained with the published 2026 source year and should not be read as a current ranking. Its competitive position is supported by innovation capacity, scalable platforms, technical talent, and global distribution. Operations of this scale typically span multiple regions, customer groups, suppliers, and regulatory environments, making consistent governance and performance measurement central to long-term strategy. From a corporate-responsibility perspective, the most material research questions concern responsible technology, data privacy, cybersecurity, resource-efficient infrastructure, and digital inclusion. Impact500 evaluates the company through environmental performance, financial responsibility, philanthropy, and ethics. The profile therefore emphasizes comparable disclosure, evidence of implementation, board and executive accountability, and year-over-year outcomes. Company-specific assertions remain linked to cited evidence; modeled indicators and sector-based research guidance are labeled separately until analyst verification is complete.
