TÜV SÜD Launches the First-of-Its-Kind OT Risk Assessment as a Service (OT-RaaS) for Secure Multi Sector Industrial Operations

Amid rising cyber threats targeting industrial systems and increasing regulatory expectations for operational technology (OT) security, TÜV SÜD, one of the world's leading testing, inspection and certification (TIC) organizations, today announced the launch of the first-of-its-kind OT Risk Assessment-as-a-Service (OT-RaaS), a subscription-based offering designed to help organizations proactively identify, assess, and manage cybersecurity risk across OT environments.

"Operational technology security is essential for protecting people, facilities, production, and supply continuity," said Sivakumar Radhakrishnan, Senior Cybersecurity Expert, TÜV SÜD. "As industrial systems become more connected, the attack surface for OT environments continues to grow, while geopolitical risks and cybersecurity mandates are accelerating. OT-RaaS reflects the shift toward continuous OT security, enabling organizations to identify risks early and strengthen operational resilience. TÜV SÜD believes this ongoing assessment model will become a cornerstone of industrial cybersecurity as global standards and regulatory frameworks mature."

The service provides continuous, repeatable OT risk assessments for industrial production environments, covering OT assets and systems that could serve as potential entry points for cyberattacks. Leveraging TÜV SÜD's global expertise in industrial cybersecurity, testing, inspection, and certification with more than 30,000 employees worldwide, the approach integrates into established plant maintenance and engineering workflows. This allows on-site teams to receive actionable findings and prioritized recommendations from an independent, trusted thrd party without disrupting operations.

From Reactive to Proactive OT Risk Management
Many organizations assess OT risk only after a disruption, audit finding, or incident. At the same time, the threat landscape is intensifying: operational technology has become a prominent target for cyber attacks, with industrial sectors such as manufacturing and energy particularly exposed. The growing connectivity of industrial systems is further increasing their vulnerability, especially to ransomware and other disruptive attacks.

TÜV SÜD's OT-RaaS is designed to establish an ongoing assessment cadence, enabling continuous visibility into risk posture and risk drivers as environments evolve such as changes in connectivity, vendor access, asset lifecycle, or maintenance practices.

Subscription Model with Three Engagement Tiers
Following an initial baseline assessment, TÜV SÜD offers OT-RaaS through three subscription tiers - high-risk, medium-risk, and low-risk - enabling organizations to align assessment frequency with their operational risk profile and cybersecurity priorities.

Optional add-on modules are available, including compliance mapping against relevant requirements and standards such as NIST CSF 2.0, IEC 62443, ISO 21434, and TS 50701. The service supports organizations across industries including manufacturing, utilities, oil and gas, automotive, and rail. For example, manufacturers can use OT-RaaS to identify vulnerabilities that could lead to ransomware-related production downtime, utilities can align OT risk management with regulatory frameworks such as NERC CIP, and automotive or rail operators can strengthen system security and compliance with standards like IEC 62443 and ISO 21434 as connected and automated systems expand.

Early, Practical Improvements
Customers receive a prioritized risk register and remediation roadmap as part of the service deliverables, enabling teams to address high-impact issues first and track progress over time. The OT-RaaS methodology follows a continuous improvement workflow which includes - baseline assessment, ongoing monitoring, risk identification, remediation planning, and recurring review - helping organizations maintain visibility into evolving OT risk.

Meet TÜV SÜD at RSAC

TÜV SÜD will present OT-RaaS at the RSAC Conference 2026 in San Francisco. Attendees can visit Booth 5469-7 (German Pavilion) to learn how this service provides continuous visibility into OT cybersecurity risk and supports proactive risk management across industrial environments. Sivakumar Radhakrishnan, Senior Cybersecurity Expert at TÜV SÜD, will be available for on-site discussions and media interviews.
