Qubit Security is a leading Korean company providing one-stop total security services through its PLURA Web Application Firewall (WAF), Endpoint Detection and Response (EDR), and Security Information and Event Management (SIEM) system.

Unlike conventional web firewalls that can only block known signature-based attacks, Qubit Security's solutions also block unknown threats. It also provides Advanced Persistent Threat (APT) attack response capabilities against server and PC endpoints, and the integrated security event management system includes credential stuffing attack prevention. While existing products struggle to detect web-based data exfiltration, PLURA supports real-time automated response. The PLURA solution features an automated response mechanism driven by a behavior-based anomaly detection engine. The underlying technology has been patented in the United States, China, and South Korea.

Qubit Security supplies cloud-based Security-as-a-Service (SECaaS) and on-premises PLURA products to a diverse range of clients including leading global electronics manufacturers, cryptocurrency exchanges, public institutions, e-commerce platforms, e-learning companies, Korea's leading wall pad manufacturers, convenience store chains, and large conglomerates. In addition, it has recently completed proof-of-concept (POC) testing with a leading global steel company, a major domestic security firm, and a semiconductor company, with full deployment currently underway.
