Independent research firm Value Finder analyzed on April 17 that ZENYUMS is emerging as a key beneficiary as the "Mythos shock" becomes more apparent. The firm is the No. 1 provider of AI-based security solutions, specifically EDR, in the domestic public sector.
Lee Chungheon, a researcher at Value Finder, stated, "The emergence of Mythos signifies the full-fledged arrival of an era in which AI becomes a means of cyberattack," and emphasized, "The value of companies equipped with AI-based security solutions should be re-evaluated not as mere security software firms, but as AI security stocks."
The security-specialized model "Mythos" released by a U.S. AI company is known for its vulnerability detection capabilities that surpass those of human hackers, rapidly spreading shockwaves globally and prompting financial authorities around the world to respond urgently.
In fact, after the release of Mythos, U.S. financial authorities convened urgent security review meetings with major financial institution CEOs, while in Korea, the Financial Supervisory Service also called in major financial institutions for emergency response meetings. The prevailing interpretation is that supervisory policy is shifting from simple inspections to de facto mandating the adoption of EDR.
Unlike traditional antivirus solutions, EDR is a next-generation security solution capable of detecting unknown new and variant malware. Based on AI and machine learning, it can detect abnormal behaviors and trace the root cause in the event of an incident, making it an essential infrastructure in the era of AI-driven hacking.
This trend is expected to go beyond a short-term issue and lead to a structural increase in demand. Regulatory strengthening by financial authorities, amendments to the Personal Information Protection Act, and expansion of information security disclosure obligations are converging to make expanded security investments across both public and private sectors inevitable. Researcher Lee analyzed, "The Mythos issue will act as a powerful catalyst for the existing trend of strengthening security, accelerating the adoption of next-generation security solutions not only in the financial sector, but also among large enterprises and public institutions."
Against this backdrop, ZENYUMS, a leading domestic security company, is being singled out as a direct beneficiary. The company specializes in security software with a focus on network access control (NAC) and EDR. It holds a 71% market share in the domestic NAC market and a 46% share in the EDR market. Its competitiveness is further highlighted by its ability to cross-sell EDR to its base of more than 3,000 NAC clients.
Researcher Lee stated, "As the No. 1 player in the domestic public sector EDR market, the company is the top pick in this situation," and assessed, "If demand for EDR adoption rises among financial institutions and large corporations, the order pipeline could rapidly expand."
Furthermore, product portfolio expansion is also viewed positively. ZENYUMS is evolving into an integrated endpoint protection platform (EPP) by launching antivirus (AV) solutions in addition to its existing NAC and EDR offerings. This is expected to supplement the limitations of the traditional antivirus market and serve as a new growth engine. Researcher Lee explained, "The integrated platform strategy encompassing EDR, AV, and NAC is a key element in strengthening customer retention."
The policy environment is also favorable. As the government pursues "Sovereign AI" with the aim of becoming one of the top three AI powerhouses, "Sovereign Security" has emerged as a core agenda. This is leading to increased localization of security solutions, providing structural benefits to domestic security companies.
Global expansion is also gaining momentum. ZENYUMS is strengthening its overseas market strategy, focusing on the Middle East and the United States, and is establishing a competitive edge in the Middle East, where there is high demand for on-premises security solutions. Its global customer and partner network is also rapidly expanding.
From a business performance perspective, there is ample room for growth. The so-called "triple factors" of regulatory strengthening, new product launches, and transition to a subscription model are expected to drive earnings improvement. Shareholder return policies also enhance investment appeal. The company is making clear its commitment to boosting shareholder value by combining share buybacks with a high-dividend policy.
Researcher Lee Chungheon diagnosed, "The current stock price does not fully reflect the structural expansion of security demand in the AI era and the value of the platform shift," adding, "The company has entered a phase where its valuation is being reassessed as a structural growth stock for the AI security era."
