South Korea Security as a Service Market

South Korea Security as a Service Market Overview:

The South Korea security as a service market size reached USD 358.30 Million in 2024. Looking forward, IMARC Group expects the market to reach USD 1,038.37 Million by 2033, exhibiting a growth rate (CAGR) of 12.55% during 2025-2033. Rising cyber threats, rapid Internet of Things (IoT) device adoption, and a growing support for zero-trust security models are key factors driving the security as a service market in South Korea. These trends demand scalable, flexible, and cost-effective solutions that provide continuous monitoring, real-time threat detection, and enhanced access control across diverse, complex digital environments, which is contributing to an increase in the South Korea security as a service market share.

South Korea Security as a Service Market Trends:

Rising Cybersecurity Threats and Digital Vulnerabilities

As the nation progresses in its digital economy and incorporates technologies like cloud computing, artificial intelligence (AI), and IoT, its infrastructure grows increasingly susceptible to cyber threats aimed at essential sectors such as finance, manufacturing, and government. Organizations are reacting by implementing scalable, strong security frameworks that can be rapidly deployed. Security as a service (SECaaS) offers ongoing updates, threat insights, and specialized oversight without significant initial expenses, rendering it an economical defense approach. For instance, the Korea Internet & Security Agency (KISA) indicated a 48% increase in cyber incidents in 2024, with occurrences rising from 1,277 to 1,887. This increase, along with local geopolitical conflicts, is raising awareness and prompted both public and private sectors to delegate cybersecurity tasks to specialized providers for more proactive and robust threat management.

Increased Use of IoT Devices

The swift expansion of IoT devices in South Korea is generating intricate security issues that conventional defenses cannot completely solve. In 2025, Arm introduced its Armv9 Edge AI platform in South Korea, showcasing cutting-edge processors designed for IoT security and efficiency. With the growing adoption of connected devices by industries and individuals, ranging from industrial sensors to smart home gadgets, the quantity of susceptible endpoints significantly increases. Numerous IoT devices have insufficient built-in security, rendering them attractive targets for cyberattacks. SECaaS provides a unified, flexible method to oversee, identify irregularities, categorize network data, and apply regulations across various devices instantaneously. This is vital in areas, such as manufacturing, healthcare, and smart cities, where the adoption of IoT is rapidly growing.

Support for Zero-Trust Security Frameworks

The increasing implementation of the zero-trust security model is a major factor influencing the South Korea security as a service market growth. With the rise of cloud usage and remote work, conventional perimeter defenses become less effective, so zero-trust’s principle of “never trust, always verify” becomes crucial. This model necessitates ongoing authentication, detailed access management, and immediate oversight, which are functions that contemporary SECaaS platforms deliver effectively. In 2025, Naru Security introduced ZeroTiCA, a subscription-driven Zero Trust service aimed at SMEs. This service utilizes AI-driven threat detection and immediate network surveillance to uncover internal threats such as lateral movement, facilitating preemptive defense. By enabling organizations to adopt zero-trust without costly infrastructure modifications, SECaaS solutions conform to changing regulatory requirements. With support from the government and industry for zero-trust implementation, SECaaS is becoming recognized as the effective, scalable method to update security and enhance resilience throughout South Korea.
