Risk Analysis

Rhebo Industrial Protector passively records the communication of your IACS over several days. The iInstallation takes less than an hour. We then analyze all assets and their communication behavior.


You receive a comprehensive report in which all audit results are described in detail with prioritized recommendations for mitigations. Vulnerabilities, unusual network behavior and error conditions are fully documented.


At the concluding workshop, we discuss the results with you and develop a detailed action plan.
