Enphase Energy
Enphase Energy builds the hardware and software stack behind millions of distributed solar installations - intelligent microinverters, battery systems, and a companion app that gives homeowners granular control over energy production and consumption. Founded in 2006, the company has shipped roughly 87.8 million microinverters and deployed systems across more than 165 countries. That footprint makes every connected Enphase device a potential attack surface: firmware running on edge hardware in residential environments, cloud APIs handling real-time telemetry and control commands, and mobile apps authenticating users who can discharge batteries back to the grid. The threat model is concrete. Compromised microinverter firmware could destabilize local grid segments. A breach of the monitoring platform exposes energy-usage patterns for millions of households - behavioral data with real privacy stakes. Control-plane vulnerabilities in the Enphase Energy System could allow unauthorized discharge or shutdown of storage assets at scale. Security work here spans embedded firmware integrity, cloud infrastructure hardening, secure OTA update pipelines, API authentication, and mobile application security across a product line that must interoperate with virtually every solar panel on the market. Enphase operates in the distributed energy resources vertical, where grid integration demands both reliability and regulatory compliance. The company's systems need to meet evolving standards for grid-connected devices while scaling deployment velocity. Security teams work alongside firmware, cloud, and grid-integration engineers, with the understanding that a single vulnerability in a widely deployed microinverter codebase has outsized blast radius compared to a typical SaaS bug.
