CloudFastener, a fully managed security service for public cloud environments provided by Cyber Security Cloud, Inc. (Head office: Shinagawa-ku, Tokyo; President and CEO: Toshihiro Koike; hereinafter referred to as "the Company"), has been introduced by Schoo Inc. (Head office: Shibuya-ku, Tokyo; President and CEO: Kenshiro Mori; hereinafter referred to as "Schoo"), a provider of online learning services for working adults.

■Business challenges and reasons for introducing CloudFastener
With the mission of "eliminating graduation from the world," Schoo offers "Schoo," a service for adult education aimed at corporations and individuals, and "Schoo Swing," which promotes digital transformation for higher education institutions and adult education providers, and is committed to providing continuous educational support using technology.
The company was using security services such as AWS Security Hub, Amazon GuardDuty, and Amazon Inspector in its AWS environment, but as the number of services and staff expanded and the team structure strengthened, it became necessary to manage multiple services across the board, which led to issues such as an increased burden on operations and information organization. Furthermore, prior to the company's listing in 2024, the company was also working to strengthen its systems to maintain a higher level of security throughout the company. Against this backdrop, the company introduced CloudFastener as a service that could be trusted to handle all aspects of security while complementing the limited resources of its infrastructure team.

[Comment from Akihiro Kato, CTO of Schoo Inc.]
"By introducing CloudFastener, we were able to visualize the current security risks in the AWS environment and receive support from prioritizing countermeasures to cost estimation and monitoring, which enabled us to strengthen security while keeping costs down. In addition, because we received support based on a deep understanding of our team structure and application configuration, we feel that not only has the burden on the infrastructure team been greatly reduced, but we have also been able to achieve both development speed and security."
