\nCyllene has developed the RC-DC4\/5G box, a device capable of managing different internet connections while encrypting data and facilitating compliance with the European Union Network and Information Security Directive (NIS 2). Recent warnings from the European Solar Market Council and SolarPower Europe have highlighted a growing concern: the cybersecurity of PV plants.
\n\u201cSolar and wind farms, and more broadly renewable energy infrastructures, rely on increasingly distributed networks to collect data on plant productivity, outages, and other factors,\u201d said Anthony Le Fauconnier, a sales engineer specializing in managed services, cybersecurity, and telecom interconnections at France-based IT services provider Cyllene.
\nWith more than 400 employees across 13 sites in France, Cyllene supports more than 1,500 public and private clients in managing critical data and designing IT and cybersecurity architectures.
\nIn response to rising cyber risks, Cyllene unveiled its latest device at the Energa\u00efa trade show in December 2025: the Cyllene Box, also known as the RC-DC4\/5G.
\n\u201cThe goal was to replace a model based on ADSL and satellite with a system that is both more efficient and more secure,\u201d Le Fauconnier told pv magazine France.
\nThe device adapts to available connections in each area, supporting fiber, fourth-generation and fifth-generation mobile networks (4G\/5G), and, where necessary, satellite links.
\n\u201cWith multiple Ethernet ports and integrated Wi-Fi, the Cyllene Box sits upstream of network infrastructure to guarantee a secure internet connection,\u201d he explained. \u201cIt integrates a firewall and ensures encryption and authorization for all data, protecting all connected internet of things (IoT) and supervisory control and data acquisition (SCADA) equipment.\u201d
\nCyllene also operates a software-defined wide area network (SD-WAN) platform, hosted and managed in its three French data centers, responding to demand from renewable energy clients for domestic data hosting.
\nThe company currently manages 150 PV parks across France, half of which are already equipped with the Cyllene Box. \u201cBy the end of February, all parks will be migrated,\u201d said Pierre-Vincent Caisso, director of the ClientPartner and Consulting Department.
\nThe Cyllene Box is paired with a management portal that centralizes all park data.
\n\u201cIt enables dynamic network mapping of connected equipment, helping operators comply with the European NIS 2 directive, which aims to strengthen resilience against cyber threats,\u201d Caisso added.
\nThe directive requires documentation such as flow matrices, network diagrams, and replicated information across multiple backups, all of which are supported by the Cyllene Box and its management platform.<\/p>\n
