AI continues to evolve daily, and email attacks are becoming increasingly sophisticated and advanced, making it more difficult to identify the risks hidden within the emails received by employees. In this seminar, we will organize the latest trends in email attacks while clarifying the current state and challenges of training, as well as countermeasures. Additionally, as an example of countermeasures, we will introduce proven on-demand educational content and group training conducted by experienced instructors. We hope this will provide an opportunity for not only the information systems and security departments but also those involved in human resource development and information control, as well as management in operational departments, to find out what needs to be done to achieve results in phishing email training. <Session 1> Points to Review in Operations to Prevent the Formalization of Email Training Speaker: Akihiro Shida, NRI Secure Technologies <Session 2> Educational Services to Enhance Behavioral Retention and Risk Sensitivity Speaker: Yuma Egawa, NRI Secure Technologies [Target Audience] - Personnel from security and educational departments considering email training tools - Individuals conducting email training but facing challenges - Those with issues regarding in-house education

From December 10 to 12, 2025, frogblue will be exhibiting at JAPAN BUILD TOKYO, held at Tokyo Big Sight, focusing on the DX of commercial facilities and stores. You will be able to see how lighting control, roller curtain and blind control, door control, and camera-linked control are managed through a Bluetooth mesh network. This enables intelligent control by wirelessly connecting various electrical devices during the construction of new office buildings, commercial facilities, and stores, as well as during design changes of existing ones. You can freely choose the types and manufacturers of lighting and other devices, or use existing ones. After installation, if changes to settings are needed due to design modifications of the space, there is no need for cable wiring; adjustments can be made simply through app settings. This allows for cost savings both during installation and maintenance. Additionally, the wireless installation is easy, reducing construction time and keeping costs down over the medium to long term.
