PLC-OTAC by SSenStone is a security solution designed to enhance OT security for Programmable Logic Controllers (PLCs). It improves security on low-spec PLC computing resources, reducing time, cost, and manpower for OT security and management. The solution uses OTAC (One-Time Authentication Code) technology to implement a secure and advanced user authentication process, moving away from vulnerable password-based systems. PLC-OTAC is designed to address security vulnerabilities in PLC systems by replacing traditional password-based authentication methods with dynamic, non-reusable codes. It aims to prevent unauthorized access to OT and PLC equipment, particularly in industrial automation environments where PLCs are critical components.
