CATIS INC. is a South Korea-based provider of spatial perception security platforms and integrated physical security systems for critical national infrastructure and high-security enterprise facilities. Founded in 2006 and tracing its technological origins to 1994, the company is headquartered in Anyang-si, Gyeonggi-do, South Korea. CATIS delivers end-to-end security architectures across domestic and international markets, operating across core segments that include perimeter defense, access management, and centralized security monitoring. The company's product and service portfolio comprises the AxiCos integrated physical security management platform; the AxiQuant post-quantum cryptography (PQC)-enabled security platform designed to protect critical infrastructure against quantum computing decryption threats; the IHS series of perimeter intrusion detection systems (PIDS), featuring fence-mounted vibration sensors, fiber-optic perimeter detection systems, and active infrared sensors; access control and biometric identification systems, including artificial intelligence-driven facial recognition terminals and smart pass gateways; integrated video surveillance and situational intelligence software; specialized security controllers and encrypted communication modules; and turnkey security services spanning spatial risk assessment, security system engineering, customized hardware-software integration, and ongoing maintenance. CATIS primarily supplies its systems to government agencies, nuclear power generation plants, international airports, seaports, military defense installations, internet data centers (IDCs), and financial institutions. In recent major corporate developments, CATIS completed its public listing on the KOSDAQ market of the Korea Exchange through a business combination with KB No. 22 Special Purpose Acquisition Company (SPAC) in May 2024. Following its listing, the company commercially launched its AxiQuant quantum-resistant platform to meet emerging public-sector cryptography standards. In March 2025, CATIS established a strategic memorandum of understanding with Hancom WITH to co-develop and deploy quantum-resistant encryption and AI-powered facial recognition technologies. Furthermore, the company has expanded its solution ecosystem into autonomous perimeter protection through technical partnerships with industrial hardware vendors such as Advantech and the integration of quadruped robotic patrol units and unmanned aerial surveillance vehicles into its central spatial perception platform.
