Yaokin Co., Ltd. Adopts Ransomware Countermeasure Platform "Halcyon"

Takachiho Koheki Co., Ltd. (Head Office: Shinjuku-ku, Tokyo; Representative Director and President: Takanobu Ide; Securities Code: 2676; hereinafter "Takachiho Koheki") announces that Yaokin Co., Ltd. (Head Office: Sumida-ku, Tokyo; Representative Director: Masahiko Sumiya; hereinafter "Yaokin") has adopted and completed the implementation of the ransomware countermeasure platform "Halcyon".

*An "Original Umaibo" was created based on a Halcyon implementation case study. It is being used as a novelty item to make security measures feel more familiar. This novelty item is scheduled to be distributed at the Information Security EXPO (Takachiho Koheki booth), held from Tuesday, April 8, 2026, to Friday, April 10, 2026.

Yaokin Co., Ltd., which plans and sells a wide variety of playful products, from easy-to-eat snacks like "Umaibo" to amusing sweets with innovative ideas, and nostalgic treats beloved across generations, delivers products that foster children's dreams through "deliciousness" and "fun" not only throughout Japan but also worldwide. As a company handling food products, Yaokin emphasizes safe food production and stable business operations. However, in recent years, the escalating damage from ransomware attacks, regardless of industry or company size, has become a critical management issue affecting business continuity.

[Background and Overview of Yaokin's System Implementation]

At Yaokin, challenges included the impact of business system outages outside of the manufacturing site and the insufficient clarity regarding recovery prospects. Particularly, in system operations with a small team, the lack of clear role assignments and scope of response during an incident was a source of concern. With the introduction of Halcyon, the concept of "rapid recovery even if encrypted" in addition to "preventing intrusion" was highly evaluated as aligning with Yaokin's business continuity policy.

Furthermore, the ability to implement it as an add-on without conflicting with existing EDR solutions and the subscription-based model that reduces initial investment were also factors that promoted its adoption.

[Effects and Operational Aspects After Implementation]

The process from the start of consideration to implementation proceeded quickly, taking approximately two months, and the installation work and agent deployment to each terminal were completed without significant burden.

With an easy-to-understand management screen, alert notifications for abnormalities, and a monitoring system by a specialized team, a sense of security was ensured, allowing them to "rely on it in case of an emergency," while minimizing the daily operational load and impact on business.

By introducing Halcyon, Yaokin has achieved security measures based on the premise of "not stopping business even if encrypted," enhancing the continuity of core systems and internal systems, and building a security foundation that allows both management and on-site staff to focus on their work with peace of mind, even with a limited personnel system.

[Introduction of Adopted Product]

● Ransomware Countermeasure Platform Halcyon 

Even with EDR and backup systems in place for ransomware countermeasures, there are countless cases where attacker intrusion and data encryption cannot be stopped, leading to business interruptions and recovery delays. Halcyon, as a specialized ransomware solution, can be introduced to complement existing security measures rather than replace them, minimizing damage and ensuring business continuity even if an intrusion is permitted.
