About Quad Miners

Quad Miners, a cybersecurity firm headquartered in Seoul, South Korea, was established in 2017. The company was founded by four veterans of the cybersecurity industry, including CEO & Co-Founder Bumjoong Ven Park, with a team comprising three technical developers and one technical salesperson. Their journey began with research and development efforts for their core technology starting as early as 2014, three years before the company's formal inception.

The firm specializes in Network Detection and Response (NDR), providing security solutions in both cloud and on-premise formats. Its clientele includes organizations in sectors where information security is critical, such as national defense, finance, manufacturing, public services, and other enterprises. Quad Miners generates revenue by supplying its proprietary security products and associated services to companies that have a significant need or existing investment in robust information security infrastructure.

The flagship product is the 'Network Blackbox', a next-generation NDR solution designed to address a multitude of cybersecurity threats. The system functions by capturing, storing, and analyzing 100% of network traffic packets, which allows for the detection, analysis, and resolution of security events. This full packet capture provides complete visibility into network traffic, enabling the identification of anomalies and threats that might otherwise go unnoticed. The technology can reproduce content from network traffic, extract files, and uses machine learning-based models to pinpoint advanced threats, offering explainable insights into security events. This capability is crucial for identifying internal data leakage, malware, phishing, and Trojan attacks. The company also offers a 'Cloud Blackbox' to monitor and secure cloud network environments.

Quad Miners' NDR solution has been recognized by Gartner for five consecutive years. The company has secured over 25 customers across various sectors, including leading financial firms and public organizations in Korea, and is also gaining traction in the US and Japanese markets. To date, the company has raised $39.3M in funding from investors including Protech Ventures, CJ Investment, and KB Securities.
