The Acquisition Playbook.

Three patterns run through Arista Networks's acquisitions — what it looks for, how it pays, and how it folds in what it buys.

01
Acquisition criteria
Small, technology-and-talent tuck-ins, almost always cash.
Arista made no acquisitions before 2018, then settled into a cadence of small deals that add a specific technology rather than scale. Most were paid in cash and most carried no disclosed price; only Big Switch (~$73.3M), Awake Security ($180.5M) and VeloCloud ($300.0M) had public values, and none is material to Arista's financials.

02
Capital deployment
Everything gets folded into an existing Arista platform, not run standalone.
Big Switch became the DANZ Monitoring Fabric; Awake added a network detection and response platform; Untangle supplies the security layer of Cognitive Unified Edge (CUE); Pluribus went into the Unified Cloud Fabric (UCF); and Mojo, Metamako and VeloCloud extended the WiFi, low-latency and cloud-WAN capabilities of the core portfolio.

03
Integration approach
Deliberate expansion of adjacencies around core data-center switching.
Each deal pushes Arista into a neighboring domain — wireless/campus, ultra-low-latency, software-defined networking and observability, network security, cloud fabric and finally wide-area/SD-WAN networking — steadily widening the portfolio from data-center switches toward client-to-cloud networking.
