Before it is taken away! It's time to review your domain management method

A domain name is a critical business asset-and because of its value, it is constantly a target for attackers. Despite this, many companies remain insufficiently aware of the importance of domain management and the risks associated with it. How can organizations accurately identify domain related threats and implement effective protections? In this article, we explain key methods for managing domain risks and introduce practical countermeasures, including examples of our own initiatives.

The New Normal for Generative AI: What is the "Guardrail" that Protects Companies from AI Security Risks

As the use of generative AI continues to expand rapidly across companies, new security risks are emerging-such as employees using shadow AI tools and the unintentional leakage of confidential information through prompts. Traditional human centric approaches, including policy creation and employee training, are no longer sufficient to effectively mitigate these risks. To ensure safe adoption, organizations must implement technical controls capable of monitoring and managing generative AI usage in real time. In this article, we introduce the concept of AI guardrails, explain how they work, and highlight key considerations for implementing them to support the secure and responsible use of generative AI within enterprises.

Information leak? Pitfalls of using generative AI in companies

In recent years, many companies have adopted generative AI to enhance operational efficiency and productivity. Its effectiveness has been recognized in areas such as document creation, information organization, and customer support, and its applications continue to expand rapidly. However, as the use of generative AI grows, new security risks have emerged - such as the accidental input of confidential information and unintentional data leakage. Given these challenges, it is essential for organizations to understand these risks and establish clear countermeasures to ensure the safe and appropriate use of generative AI. This article outlines the key security risks companies face when using generative AI and presents fundamental strategies to mitigate them.
