Why OT security is more important today than ever before
The increasing networking of industrial plants makes operational technology (OT) an attractive target for cyber attacks. Attacks on control and production systems endanger not only data, but also security, availability and human lives. OT security protects critical infrastructures, secures production processes and is indispensable for the resilience of modern industrial companies.

An IT maintenance contract ensures defined response times, clear service levels and calculable costs. This guarantees maximum operational reliability and predictable maintenance activities.

A maintenance contract is worthwhile if you need maximum operational reliability. It regulates response times, responsibilities and ensures predictable costs - ideal for production-critical or complex IT environments.
What is the NIS2 directive and why does it affect my company?
