South Korea Network Security Market Trends:

Increasing cases of cyberattacks

Rising cases of cyberattacks are positively influencing the market in South Korea. In April 2025, Mobile network provider SK Telecom, with around 34 Million users in the country, reported that it experienced a cyberattack where malware breached its internal systems and accessed information regarding customers' SIM cards. As more individuals and organizations are going digital, the threat of cybercrimes, such as data breaches, ransomware, and phishing, is growing rapidly. Businesses across sectors, especially finance, healthcare, government, and e-commerce, are facing increasing attempts by hackers to steal sensitive information and disrupt operations. These attacks not only cause financial loss but also damage reputations and user trust. As a result, companies are prioritizing investments in network security to protect their systems, data, and customers. Many organizations are adopting firewalls, intrusion detection systems, encryption tools, and endpoint security solutions to prevent unauthorized access. Cyberattacks are also becoming more sophisticated over time, catalyzing the demand for advanced tools supported by real-time threat detection. Small and medium-sized enterprises are recognizing the importance of strong cybersecurity measures due to rising risks. Public awareness and media coverage of cyber incidents are further highlighting the need for protection. Additionally, regulatory pressure from the government is encouraging businesses to comply with security standards, propelling the market growth. As the digital landscape is expanding, the demand for stronger and more adaptive network security solutions is escalating, making it a top priority for both the public and private sectors in South Korea.

Growing AI adoption

Rising use of AI is impelling the South Korea network security market growth. According to IMARC Group, the South Korea AI market size reached USD 3.12 Billion in 2024. As companies are integrating AI into services like finance, healthcare, manufacturing, and customer support, they are handling larger volumes of sensitive data and depend more on connected systems. This shift is increasing the importance of securing networks that support AI infrastructure. AI tools also rely on fast, stable, and protected data transmission, creating the need for advanced network protection. Additionally, AI adoption is encouraging cloud migration and automation, which require stronger network security to prevent disruptions and maintain trust. With South Korea’s focus on becoming a tech-oriented economy, industries are employing AI to improve efficiency and competitiveness. Government support for AI research and smart industry growth is adding momentum, driving the demand for secure, AI-compatible network environments. As AI continues to reshape operations and communication, the demand for strong network security frameworks is rising, ensuring stable and safe digital progress across South Korea’s economy.
