About ESTsecurity

ESTsecurity Corp., a South Korean cybersecurity firm established on January 2, 2017, is helmed by CEO Jinill Jung. The company operates primarily in the endpoint security market, providing solutions for both individual users and enterprise clients, including government institutions. Its business model centers on offering both free and paid versions of its software, with revenue generated from enterprise solutions and a focus on recurring subscriptions.

The firm's core technology leverages artificial intelligence and deep learning to power its threat detection and analysis capabilities. This is built upon a substantial foundation of data collected from its large user base, which exceeds 16 million users and helps detect over 190 million malware instances annually. A key component of its operations is the ESTsecurity Security Response Center (ESRC), established in January 2017. The ESRC is staffed with threat analysis experts who focus on cyber threat intelligence (CTI), tracking global threats, and collaborating with South Korean government agencies to safeguard against sophisticated cyber attacks. The center analyzes over 15 million malware samples monthly, with a particular focus on threats targeting South Korea.

ESTsecurity's product portfolio is centered around endpoint and data security. Its flagship product, ALYac, is an antivirus program that has been in development since 2007, predating the formal establishment of the company. For enterprise clients, the company offers ALYac EDR (Endpoint Detection and Response), which provides proactive threat blocking based on the company's extensive user data. Other key products include Threat Inside, a malware analysis and intelligence service that utilizes multiple analysis engines to provide detailed reports, and Dr. Capsule, a free antivirus and protection application for Android devices. The company also provides solutions for patch management and data security, such as SecureDisk and InternetDisk.
