Korean startups in the cybersecurity sector have been coming out with products and services for many years now. The demand now is higher than ever before. You can see this in that South Korea has a major shortage of experienced cybersecurity professionals to fill open positions. The high demand is that cybercrime is estimated to reach $10.5 trillion annually by 2025. However, with the advancement of AI, machine learning and a new breed of hackers, cybersecurity startups in Korea have been attracting a lot of funding to develop products or services to secure applications for remote workers and product users data as it travels from the cloud to IoT devices.

The cybersecurity sector is growing in Korea due to the constant digital transformation, regulatory compliance, increased security threats, and the need for faster, more efficient response capabilities. Many investors in Korea see cybersecurity investments as a safe investment as the startups are solving security challenges that are not going away anytime soon. Here are Korea’s top cybersecurity startups to watch for in 2024.

Top Cybersecurity Startups in Korea


Korean Fintech Startup SsenstoneKorean Fintech startup SsenStone is a digital security startup that offers a safer way for online credit card use. It produces a one-time credit card number that changes every time a new transaction is made.  The technology is called Virtual One Time Code (VOTC). VOTC creates a virtual number that cannot be duplicated for more than 1 million uses. In addition, the number recognizes the cardholder every time without any network connection. While there has been a lot of security improvement regarding offline card transactions, there are few in the online space. More than 70% of credit card fraud cases come from online/eCommerce transactions.

EYL offers the World’s “Smallest, Cheapest, Fastest & Most Energy-efficient” Quantum Random Number Generators & Applications. Developed by EYL, the quantum random number generator is a unique and innovative technology that provides the ultimate randomness that can improve information security.

Currently, most encryption systems use random numbers generated by software algorithms (pseudo-random number generators) as keys for their convenience and speed, but they are increasingly vulnerable to hacking. Therefore, hackers can steal or guess encryption keys, made easier by weak entropy produced by poor random number generators.
