Arista has more than 10,000 cloud customers and operates offices around the world. Its portfolio includes data center switches, campus networking, routing, Wi-Fi and network management technologies. Arista also provides network detection and response and security capabilities designed to improve visibility into traffic and anomalous behavior. The company's technology is increasingly focused on AI networking, including high-speed Ethernet platforms designed for large-scale AI clusters.
