Private 5G networks offer significant security advantages over public networks for industrial applications, according to Janne Isosaari, Senior Director of Operations for Private Networks Europe at Boldyn Networks. These networks provide reliable and secure connectivity for critical operations and sensitive data within industrial facilities.


“Private networks are deployed exclusively for an enterprise or campus, allowing only authorized users and devices to connect,” said Isosaari. “Data is encrypted and stored locally with limited access, preventing leakage and ensuring privacy and security through private APNs.”


Isosaari acknowledged that while jamming—the disruption of wireless signals—remains a potential threat, the closed nature of private networks and their dedicated spectrum make them less susceptible compared to other wireless network solutions.


Discussing the importance of network security in industrial environments driven by Industry 4.0 advancements, Isosaari emphasized the need for a constant and reliable network connection to minimize downtime. “Securing this complex environment requires a team of experts who understand cybersecurity concerns and can maintain optimal network performance. Preventing unauthorized users and devices is crucial to limit the risk of data leakage.”


Isosaari advised companies to adopt comprehensive security strategies for private 5G networks, following ISO27001 recommendations. “Treat private 4G/5G networks like any other enterprise network by applying the same security protocols and access controls. This consistency simplifies security management and reduces the risk of introducing vulnerabilities.”


He highlighted the challenges posed by the proliferation of IoT devices, which often lack robust security features, making them vulnerable to attacks. “Patching vulnerabilities across IoT devices can be a slow and labor-intensive process. Effective management of the IoT ecosystem is essential to ensure end-to-end security,” said Isosaari.


Private networks can significantly mitigate these threats by centrally managing and authorizing devices, ensuring only approved devices access the network. “Additionally, private networks enable secure communication by encrypting all data flowing between devices, protecting sensitive information from unauthorized access.”


When asked about the differences in security implications between on-premises core and RAN versus on-premises RAN with a public core, Isosaari explained that on-premises core and RAN provide greater control over data privacy and usage statistics. “With both core and RAN within the infrastructure, customers have more control over user data and how it’s handled, allowing for stricter access control and encryption policies.”


“While on-premises core offers more control over data privacy, overall security depends on the network design and security practices,” he added.
