Beyond Remote Access: How CDR and Zero Trust Protect Modern OT Environments
9
9:00 AM - 9:45 AM
OT environments are under increasing pressure—from rising cyber threats to new regulatory requirements across the UK and Europe. At the same time, organisations must enable remote access for vendors, engineers, and operators while maintaining strict security and operational uptime.
In this webinar, Xona and OPSWAT explore how modern OT security strategies are evolving to meet these challenges. We'll discuss how Zero Trust remote access can reduce exposure in critical infrastructure environments, while Content Disarm and Reconstruction (CDR) provides proactive protection against file-borne threats entering sensitive networks.
Together, Xona’s secure remote access platform and OPSWAT’s advanced file sanitisation technologies address a critical but often overlooked risk: malicious files moving through legitimate operational workflows such as maintenance, patching, and vendor support.
Join us as we examine:
· How new legislation and regulatory pressure in the UK and Europe are reshaping OT security expectations
· Why file transfers remain one of the most common attack paths into OT environments
· How Zero Trust access combined with CDR creates a layered defense for remote operations
· Best practices for secure patching, file handling, and vendor access in industrial networks
· How the Xona + OPSWAT partnership enables secure, operationally efficient workflows without disrupting productivity.
Whether you're responsible for OT cybersecurity, critical infrastructure protection, or industrial operations, this session will provide practical insights into securing remote access and file flows without slowing down the systems that keep industries running.

Stefan Liversidge
OT Security Product Owner
Many people securing industrial systems have never operated one. Stefan has spent years designing and deploying automation systems across some of the most demanding operational environments in the world — water treatment, oil & gas, food & beverage. He knows how these systems are built, how they’re run, and critically, how they fail.
That background changed how Stefan think about OT cybersecurity entirely.
The biggest risk in critical infrastructure isn’t sophisticated nation-state attacks. It’s the gap between the people who understand operational technology and the people tasked with securing it. That gap is where incidents happen.
Stefan works at that intersection — bringing together deep automation expertise (Siemens S7, PCS7, WinCC, Schneider, Wonderware) and hands-on security practice (GICSP, GPEN) to help operators build security programmes that work in the real world, not just in a compliance document.
Stefan's focus is on practical, pragmatic risk management — network monitoring, anomaly detection, vulnerability assessment and security strategy for OT environments where uptime and safety aren’t negotiable.
He writes about the realities of industrial cybersecurity — the technical, the organisational, and the human challenges that don’t make it into the whitepapers.
