swIDch Ltd Information

swIDch stops OT attacks at the access layer by securing the most vulnerable endpoints in critical infrastructure. By utilising our patented OTAC (One-Time Authentication Code) technology, we provide a standalone authentication solution that eliminates the inherent risks of static passwords and shared credentials. Our unique approach ensures robust protection for essential assets—including PLCs, HMIs, and SCADA systems—without requiring any modifications, firmware updates, or replacements to existing legacy equipment. This non-invasive deployment allows infrastructure operators to fortify their security posture while maintaining total system availability and operational continuity. Designed for the complexities of the factory floor, our technology functions flawlessly in air-gapped or network-less environments where traditional security measures often fail. We empower global organisations to meet stringent cybersecurity standards, such as NIS2 and IEC 62443, by closing the security gaps at the industrial edge and protecting critical digital identities at the source.
