CSE-Engineering Center of Safety Excellence GmbH

Digital solutions for process and plant safety

Digital technologies in process and plant safety today are both an opportunity and a risk. In our DIGITAL ENGINEERING division we are dedicated to both.

With our Software CSE PROSaR, for example, we are currently creating a new digital standard for the web-based design of safety-related components such as rupture disks and safety valves.

On the other hand, with the CESIS Group we have created a platform on which Plant Safety and Security merge into an innovative Plant Security. Here you will find an overview.


The unique web-based sizing app for your safety devices.

Plant Security:

How Plant Safety and Security merge into an innovative concept.

Sizing of safety devices:
Simple. Fast. Online.

CSE PROSaR CSE PROSaR is a new, unique software for sizing your safety devices. Calculate safety valves, rupture disks or combinations of both within minutes. Check existing calculations or calculate complex isometrics.

The current development status as well as all relevant information about CSE PROSaR can be found at any time on the program’s website.

Clear and intuitive operation:

PCT safety devices and application software.

Today, more and more safety devices are controlled, secured and monitored by process control systems. For this purpose, they must be designed according to complex regulations to be reliable, fail-safe, highly available and durable. The obligation to provide comprehensive documentation can also make approval procedures difficult.

The experts of CSE-Engineering provide you with comprehensive advice on this topic. We will design (safety-related) PCT equipment for you in accordance with current standards and develop the necessary application software.

Sizing according to
IEC 61508 | 61511:

Concept development:

  • Implementation of the safety life cycle
  • Risk analysis (HAZOP, LOPA)
  • Safety Integrity Level (SIL) according to VDI 2180
  • Preparation of the requirement and functional specifications

Software development siemens- | Hima systems:

Applikations Software:

  • Safety-related/ Failsafe Programming
  • Visualization on operating and monitoring level (OS)
  • Validation and verification
  • Factory / Site Acceptance Tests
  • Documentation


Safety meets Cyber Security.

The more digital technologies find their way into security technology, the more important the integration of methods and instruments of cyber security into process and plant security becomes. At the CSE we have therefore coined the term PLANT SECURITY and have gained a strong partner in 8COM. Together we offer you a comprehensive portfolio for the IT/OT consideration of your systems.

In our Leadership Group CESIS, PLANT SECURITY becomes part of our program. In regular meetings and extensive investigations, a growing number of companies dedicate themselves with us to the protection against attacks by third parties.

Consulting on national und international Standards:

  • IEC 61501/11
  • ISO 27000
  • ISO 62443
  • NA 163
  • KAS

Risk and hazard analyses

Weak point analyses and penetration tests for plants and plant components.

Assessment of effective countermeasures and development of security concepts and guidelines.

Development of a Functional Safety Management (FSM)

Plant Security Awareness Training for OT and IT staff
