NDIAS, Ltd. is working in the field of the automotive security, and provides the services including a security evalution of in-vehicle equipments and technology consulting to our customers. Although the security needs for that has increased year by year as a connected service joining vehicles and external systems together spreads, there was the lack of the resources available compared to their needs. We entrusted a part of our propositions including a technical survey to Ricerca Security Inc. since not only we have been familiar with their members for a long time, but also they are known to have top-tier skills in Japan. They achieved more than excepted for such entrusted surveys in the limited amount of time, and it also resulted in a higher level of our customer satisfaction. We believe that the security needs for automotives will continue to be high. We would like to keep co-operating with Ricerca Security Inc., and providing high quality security services to our customers.

We, Seven & i Holdings Co, Ltd., organize security and vulnerability assessments for our group companies. Every day, we check if the systems that handle customer information are taking security measures and operating without vulnerabilities under each service provided by our group companies. Under such circumstances, we asked Ricerca Security Inc. for security assessments for especially important systems dealing with personal information since they offer security services based on their high technological capabilities. Specifically, they carried out security assessments from internal logic of the system to the program syntax and contributed to spot and resolve vulnerabilities before releasing to a production environment. We and Ricerca Security Inc. are going to sign the contract for extensive supports not only for vulnerability assessments, but also for a consulting to strengthen our groups’ security management system with their expertise.
