About this episode
The episode discusses the importance of Secure Remote Access in enhancing OT security amidst the convergence of IT and OT systems.
As OT systems go online, controlling access becomes more critical than enabling it. In this episode of the Analyst Chat, KuppingerCole analysts Matthias Reinwarth and Warwick Ashford dive into one of cybersecurity’s most overlooked domains: OT (Operational Technology) security. As industrial systems become increasingly connected, the traditional boundaries between IT and OT are dissolving, bringing new risks and new security imperatives. Key Topics ✅ The rise of Secure Remote Access (SRA) in OT environments ✅ Why VPN-based access falls short for industrial systems ✅ Zero Trust and identity as the new security control plane ✅ Regulatory drivers (e.g., NIS2) and auditability requirements ✅ Convergence of PAM, SRA, and third-party access governance ✅ The growing role of non-human identities in Industry 4.0 Identity is no longer just part of security, it is the control plane for modern cybersecurity.
