Company profile

researched Aug 2026

Quad Miners (쿼드마이너) is a South Korean cybersecurity company that builds network traffic analysis, threat detection and response, and security incident investigation products. Its core technology is a high-performance full-packet capture database that collects network traffic, combined with an AI analysis engine that identifies and visualizes situations from the captured data, supporting intelligent network forensics for packet analysis and threat detection against both known and unknown threats.

The product line consists of three offerings. Network Blackbox is a next-generation NDR (Network Detection and Response) solution that performs full inspection of traffic on a full-packet-capture basis to automate security operations, providing hunting, investigation, detection and response capabilities, TTP matrices derived from expert analysis of attack tactics used by malicious groups, automated risk scoring for attack surface management based on profiled information, and explainable evidence for detected threats. QUADX is an XDR (eXtended Detection and Response) platform for zero-trust environments that uses Network Blackbox as a sensor and integrates SIEM and SOAR functions into a console, automating the full detection-analysis-response cycle on the basis of original evidence data supplied by the sensor. APTRCENTER is an integrated file quarantine system for countering advanced persistent threats; it judges and responds to the maliciousness of original files exchanged between external and internal networks and within internal networks, visualizes file data flows, and integrates with various dynamic and static analysis appliances.

Business model

Quad Miners sells enterprise security products—Network Blackbox (NDR), the QUADX XDR platform and the APTRCENTER file quarantine system—to organizations that deploy them within their own networks, and reports secured contracts with financial groups, government agencies and international clients.

Traction

Reported contracts with financial groups, government agencies and international clients in Indonesia and Japan, and publishes implementation case studies spanning a government office, a manufacturer, a securities company, a bank and a military customer.

Latest developments
