Plannitnet Files Domestic and International Patents for 'QUIC Protocol Blocking Technology'

Plannitnet announced on July 22 that it has filed domestic and international patents for its QUIC protocol blocking technology.

QUIC (Quick UDP Internet Connections) is a network protocol developed by Google. With its high transmission efficiency and multiplexed transmission capabilities, it has been adopted as a standard by the Internet Engineering Task Force (IETF). It serves as the foundational transport protocol for HTTP/3, the next-generation internet protocol, and is regarded as a potential replacement for TCP (Transmission Control Protocol).

QUIC-based traffic is characterized by a higher level of encryption and limited identifiable information compared to traditional TCP·TLS-based web communications. However, there is currently a lack of appropriate harmful content blocking solutions. As a result, attempts to distribute harmful content by exploiting this protocol are rapidly increasing.

Plannitnet's 'QUIC protocol blocking technology' directly targets this vulnerability. The technology extracts domain information from encrypted QUIC packets and blocks traffic in real time. It can be applied in both inline and out-of-band network environments. Unlike conventional DNS-based blocking methods, it is capable of blocking even encrypted HTTP/3 traffic, establishing a differentiated technological advantage that allows proactive response to advances in network technology.

This technology is currently undergoing a domestic patent application process, and with the recent filing of international patents in major Asian countries such as Taiwan and Vietnam, it is expected that Plannitnet's 'QUIC protocol blocking' technology will be recognized both domestically and internationally.

Plannitnet possesses advanced real-time harmful content blocking technology with an accuracy rate of 99.9% through its proprietary AI deep learning technology. The company also has the capability to detect and filter new types of harmful content emerging from the advancement of the internet environment. By collaborating with major domestic telecommunications companies such as KT, SKT, and LG U+, Plannitnet has built a strong trust network and has played a leading role in the internet harmful content market for approximately 20 years.

Looking ahead, Plannitnet plans to proactively apply its patented technology in harmful content filtering and network security fields through partnerships with its collaborators. The company is currently developing next-generation web traffic filtering solutions based on its proprietary technology, and ultimately aims to expand its network harmful content blocking business in the Asia-Pacific region.

A Plannitnet representative stated, "This patent application is not just a simple technology filing, but an important step in securing leadership in next-generation HTTP/3 security technology," adding, "We will continue to advance related technologies and maximize our competitiveness in both domestic and international internet markets."
