About Us
Independent IEC 62443 Expertise
We support manufacturers and operators in securing OT/IACS products, systems, and SDLCs according to IEC 62443.
Our focus spans the full IEC 62443 series: from high-level risk assessment (3-2) through system and component requirements (3-3, 4-2) to secure product development lifecycles (4-1). We advise on initial alignment as well as the evolution of existing security programmes.
