Sun King, founded in 2009, is a large-scale off-grid solar provider operating across Africa and Asia. The company designs, manufactures, and installs solar systems - ranging from basic lanterns to multi-kilowatt setups that replace utility connections - for households without grid access. That integrated model extends through last-mile delivery, installation, and long-term warranty support, backed by a field workforce of over 37,000 agents.
The cybersecurity challenge here is defined by scale and geography. Over 26 million homes powered means a massive attack surface across consumer devices, embedded firmware, and distributed logistics systems. The pay-as-you-go financing layer - through which Sun King has extended over $1.5 billion in solar loans, roughly two-thirds of them to first-time credit users - introduces payment processing, mobile money integrations, and sensitive financial data as core threat domains. Security teams are protecting not just corporate infrastructure but the trust of users who may be navigating formal financial systems for the first time.
Operational technology meets fintech at the edge: IoT-enabled solar hardware, remote provisioning, payment gateway security, and field-agent tooling all demand coverage. The perimeter isn't a data center - it's millions of deployed devices across two continents, connected to financing platforms that handle real money in real time. That's a threat model worth taking seriously.
