Critical IoT connectivity experts.

Cybersecurity doesn’t sit at the edge of CSL’s offerings—it’s at the heart. From IoT SIMs and routers to private broadband and rSIM solutions, robust protection is built in—because when lives, revenue, or infrastructure are on the line, connection without security isn’t enough.

We’re proud to announce that CSL has been named one of the UK’s Best Workplaces for Wellbeing™ 2025 by Great Place to Work UK, placing 13th in the Large Company category.

As the global shift toward electric vehicles (EVs) accelerates, the demand for secure, reliable, and scalable EV charging infrastructure is more critical than ever. The Open Charge Point Protocol (OCPP) has emerged as the de facto industry standard for enabling communication between EV chargers and Charging Station Management Systems (CSMS), driving interoperability and innovation across the sector. When paired with real-time artificial intelligence (AI), OCPP becomes even more powerful, capable of proactively mitigating cybersecurity threats, optimising energy usage, and enhancing overall system performance. This article explores the evolving role of OCPP and AI in securing EV charging networks.

CSL has expanded its Satellite Connectivity portfolio, offering customers and partners even greater flexibility, performance, and coverage for critical connectivity requirements.
