Tatum Security, a Korea-based cloud security specialist, has secured a Series A bridge investment from Samsung Venture Investment and SJ Investment Partners. The company did not disclose the investment amount.

Tatum Security provides a unified security platform that addresses various security requirements within cloud environments through a single product. With this latest funding, the company plans to accelerate its growth strategy, focusing on product enhancement, talent acquisition, and international expansion—in that order.

“This investment validates Tatum Security’s cloud security capabilities,” said Hyukjae Yang, CEO of Tatum Security. “The funding will serve as a driving force for us to pursue both AI for Security and Security for AI initiatives beyond traditional cloud security.”

Yang explained the strategic connection between AI and cloud infrastructure: “Since AI runs on cloud-based infrastructure, there’s an inherent connection between the two. Going forward, we’ll expand our capabilities to protect AI systems themselves, while internally leveraging Agentic AI to minimize repetitive operational tasks for security personnel and enhance our product offerings.”

The company’s primary customer base comprises financial institutions, with plans to strengthen its go-to-market strategy across enterprise and public sector markets. Tatum Security has also set an ambitious vision to achieve triple annual revenue growth, targeting unicorn-level expansion.

The company emphasized its commitment to strengthening product competitiveness by simultaneously addressing security and compliance requirements. This dual approach aims to solidify its leadership position in Korea’s cloud security market while launching full-scale international expansion efforts, building on its established brand leadership in the domestic market.
