CloudFastener, a fully managed security service for public cloud environments provided by Cyber Security Cloud, Inc. (Head office: Shinagawa-ku, Tokyo; Representative Director, President and CEO: Toshihiro Koike; hereinafter referred to as "the Company"), has been introduced to Open House Group Co., Ltd. (Head office: Chiyoda-ku, Tokyo; President and CEO: Arai Masaaki; hereinafter referred to as "Open House Group"), a company that operates a diversified real estate business mainly in urban areas.

■ Reasons for introducing CloudFastener
As the Open House Group accelerated its M&A activities, the number of systems it had was rapidly increasing. However, because each company operated its own systems according to its own standards, security management became inconsistent across the group, making it difficult to implement unified measures.
In order to maintain and improve the credibility of a company, strengthening security, or in other words, strengthening "defense," is becoming more important than ever.
As the development of IT infrastructure, particularly in cloud environments, progresses, formulating security policies specific to the cloud and establishing a unified operational system have become urgent issues.
Against this background, the company introduced CloudFastener as it worked to review and strengthen its security system from a company-wide perspective.

[Comment from Masaru Ito, Manager of the Infrastructure Group, Information Systems Department, Open House Group Co., Ltd.]
"CloudFastener" goes beyond simple security outsourcing and also provides consulting functions such as user education and awareness support, which we believe will contribute to strengthening our long-term security foundation.
Another big attraction is that it visualizes the security status of the entire cloud environment, centered on AWS, and allows the creation of an operational system based on a unified policy. The introduction of CloudFastener has not only resolved the shortage of human resources, but also helped to resolve issues such as dependency on individual personnel.
In the future, we are also considering entrusting them with security operations for Google Cloud.
As a group, we feel that we now have the foundations in place to build a robust security system.
