Cybersecurity · OT security

Secure automation – together with experts.

Industrial cybersecurity is a field of its own, highly specialised. On these topics we work closely with proven security partners – so you get secure, reliable automation and the necessary specialist knowledge from a single source.

Why it matters

OT security is different from IT security

Industrial plants have their own requirements – shaped by maximum availability, long life cycles and grown environments.

Connected production

More connectivity, remote access and IIoT increase the attack surface of industrial plants.

Availability first

In OT, maximum plant availability counts – protective measures must secure operations, not disrupt them.

Long life cycles

Plants run for decades. Grown legacy systems need special, well-considered protection.

Our approach

Together with specialised security partners

Automation is our core business. For industrial cybersecurity we deliberately bring proven experts on board who deal with nothing else every day.

For you this means: a single point of contact, end-to-end responsibility and an approach based on recognised standards such as IEC 62443 and the defense-in-depth principle.

  • Proven cybersecurity experts in the network
  • One point of contact for automation and security
  • Approach based on IEC 62443 & defense-in-depth
  • Focus on the availability of your plant

Topic areas

What we cover with our partners

From the initial assessment to ongoing protection – the specialist topics are handled by our partners, coordinated through Lienhard Automation.

Zones, cell protection and perimeter protection following the defense-in-depth principle.

System hardening & patch management

Hardening of systems as well as vulnerability and update management.

Monitoring & incident response

Monitoring, backup/recovery and a clear plan for emergencies.
