Assess OT security with IRMA® Security Appliance

The first step toward security with IRMA® OT-EVAL
We can help you to get started with Operational Technology (OT) security so you can gain experience and evaluate your production or plant more transparently. Using IRMA® OT-EVAL, our analysis provides a transparent system overview and recommendations on how to secure your production system against attacks in the future with targeted measures. We chose IRMA® because this security appliance is already proven in industrial use for many years in various sectors. Additionally, IRMA® was developed considering the latest security requirements (incl. KRITIS / IT-SiG 2.0) in Germany.

We help you to better understand your network

Our evaluation is based on the use of IRMA® Security Appliance to independently record and analyze assets, devices and their data connections. No specialized knowledge is required to analyze and check your network.

Our analysis will provide details about your network without specialized knowledge through a step by step, logical click-by-click sequence. Based on this compiled information, our network and OT security specialists evaluate possible threats and risks in the next step.
