Autonomous Driving Security Solution Provider Saesoltech Secures 10 Billion Won Series B Investment

Smilegate Investment Leads Series B Funding
FuturePlay Joins as Existing Investor

Saesoltech, a company developing autonomous vehicle and mobility security solutions, announced on September 1 that it has successfully secured a Series B investment of approximately 10 billion won, bringing its total accumulated funding to around 13 billion won in just four years since its founding. Smilegate Investment led this round, with existing investor FuturePlay also participating.

Saesoltech provides vehicle-to-everything (V2X) security solutions that enable autonomous vehicles and various mobility services to exchange data in a trustworthy manner. Its core technology, the Security Credential Management System (SCMS), acts as a certification security key that allows autonomous vehicles, roads, and transportation infrastructure to safely exchange information, effectively blocking security threats that may arise during communication processes.

Notably, the company’s solution offers much faster authentication and issuance speeds compared to conventional methods, reducing work time from several minutes to just a few seconds, and its automatic configuration feature enhances both stability and productivity. Saesoltech has demonstrated its technological prowess by winning awards in domestic and international competitions and tests, and is leading the establishment of international standard test specifications for autonomous vehicle security, spearheading global standardization efforts.

Recently, following the completion of WebTrust certification-a core requirement for global security authentication systems-Saesoltech achieved the milestone of being officially listed on the ‘Production Certificate Trust List (CTL)’ of the North American V2X security policy organization, SCMS Manager. This marks the first time a company outside North America has achieved this, securing Saesoltech’s qualification to enter the North American market.

A Saesoltech representative stated that the newly raised funds will be focused on strengthening research and development, expanding into overseas markets, and securing key talent. The company aims to accelerate the development of next-generation V2X security technology and solidify its position as an essential security infrastructure provider for the era of autonomous driving.

Han Junhyeok, CEO of Saesoltech, commented, “The era of fully autonomous driving cannot arrive unless communication safety is guaranteed. We aim to establish ourselves as a leader in the global V2X security market and help accelerate the commercialization of autonomous vehicles.”

Suh Kyunggu, Executive Director at Smilegate Investment, explained the investment background, stating, “The global V2X market is rapidly expanding, driven by the explosive growth of autonomous vehicles and smart cities. Saesoltech possesses unrivaled technology that leads international standards, giving it significant potential to grow into a global unicorn.”
