P-Net Profinet stack now even more robust In May 2025, Nozomi Networks Labs ran an extensive fuzz testing campaign against P-Net version 1.0.1, our open-source C implementation of the PROFINET protocol. This in-depth analysis uncovered 10 memory corruption vulnerabilities, all associated with UDP-based RPC handling. The vulnerabilities included heap-based buffer overflows, out-of-bounds reads and writes, […]

The Cyber Resilience Act, effective December 2024 with obligations from December 2027, introduces robust cybersecurity requirements for products with digital elements. This regulation aims to enhance security across lifecycles, mandating secure design, lifecycle updates, and third-party certifications. How will this impact industrial communication protocols?

As industries become increasingly connected, the need for robust cybersecurity measures within industrial networks increases. Industrial Ethernet, an essential component of modern automation, not only enables seamless communication but also carries the responsibility of ensuring secure data exchange between interconnected devices. Cyber threats are evolving at a rapid pace, and the vulnerabilities in operational technology (OT) can lead to substantial operational and financial losses. This article explores the key principles of cybersecurity in industrial Ethernet and how RT-Labs' FSoE product provides an excellent example of security implemented at the foundational level.
