Operational technology (OT) environments weren’t designed for today’s level of connectivity.
IT/OT convergence is accelerating. Remote access is expanding. Assets are more distributed — and legacy systems remain in operation.
At the same time, cyber risk is increasing.
Secure-by-design RTUs and edge systems for modern OT environments
Manufacturing accounts for 24.6% of global cyber incidents — the highest of any sector, according to IBM.
Yet organisations are expected to modernise while maintaining OT cybersecurity, availability, and compliance.
Most approaches rely on bolt-on controls or checkbox compliance.
But in industrial environments, that’s not enough.
Security must be built into the system, not added later.
Ovarro delivers secure-by-design OT systems aligned with IEC 62443, combining:
- Secure development lifecycle practices, validated through IEC 62443-4-1 ML2 certification
- RTUs designed as security enablers, supporting segmentation, least privilege, and auditability
- Platform-level security and governance, enabling secure remote access across distributed assets
Why it matters
- Reduce supplier risk with IEC 62443-compliant development
- Strengthen OT cybersecurity in industrial environments
- Enable secure remote access across distributed infrastructure
- Maintain operational continuity while modernising OT systems
Ovarro’s IEC 62443-4-1 ML2 certification validates a secure software development lifecycle, including its application within the TBox platform.
This is not just compliance. It’s repeatable, auditable secure engineering for OT environments.
