swIDch is an authentication technology company that develops and provides passwordless authentication solutions based on its proprietary OTAC (One-Time Authentication Code) technology. The company focuses on securing operational technology (OT) environments and critical infrastructure systems, addressing authentication challenges in industrial control systems, manufacturing plants, power grids, water facilities, and other OT networks where traditional password-based authentication creates security vulnerabilities. The company's flagship product, OT Auth, delivers dynamic, non-reusable authentication designed for uptime-critical environments where system availability cannot be compromised. The solution eliminates shared and static credentials, enables secure remote access, and works in both connected and off-network environments. swIDch's technology addresses the specific security requirements of OT systems, including network segmentation between IT and OT environments, real-time access monitoring, and authentication without requiring system downtime for implementation. swIDch holds over 350 patents and patent applications worldwide for its authentication technology. The company serves clients across industrial sectors that operate critical infrastructure and OT environments, providing authentication solutions that aim to prevent lateral movement in networks and reduce the attack surface associated with credential-based access. The technology is designed to function across various devices and locations while maintaining security in environments where traditional authentication methods are impractical or create operational risks.
