Waf Charm


Press release

Classi adopted WafCharm, an AWS WAF automation service provided by Cyber Security Cloud

Cyber Security Cloud, Inc. (CSC) is pleased to announce that Classi Corp., the developer and operator of Japan's largest education platform "Classi", has adopted its AWS WAF automation service "WafCharm".

■ Reasons for adoption
AWS WAF is a cloud-based web application firewall provided by Amazon Web Services (AWS), that helps protect web applications or APIs against common web exploits that could affect application availability, compromise security, or consume excessive resources.
While AWS WAF has features that allow it to be customized to the characteristics of a web application, there are also challenges, such as the need to create and fine-tune rules on your own, and the need for resources with expertise in dealing with new vulnerabilities.

WafCharm is equipped with an AI engine that uses machine learning to automatically apply the most appropriate WAF rules to AWS WAF, utilizing more than 1.5 trillion big data in total, to automatically apply the most appropriate rules for each user. WafCharm automates all the necessary operations so that users can focus on their core business rather than managing security rules.

Classi Corp. developed and operates its cloud service "Classi", which supports the adoption of ICT in school education in the four areas of adaptive learning, active learning, portfolios, and communication. As the de facto standard for school education, it is used by many teachers and students, and as of April 2020, there were 1.22 million users in high schools (Including some junior high and high school integrated schools), with 2,800 schools using it. The company has recently introduced WafCharm, an AI-based automated AWS WAF rule (signature) operation service provided by CSC.

■ Comments from Mr. Shota Umeda, Cyber Security Dept., Classi Corp.
Classi takes full advantage of AWS to deliver its services, and it is very important to us that the components are seamlessly connected to each other operationally in order to deliver services using AWS. Also, in order to focus on user experience, the operation of the WAF and the operation of the service must be considered as a set. When considering a WAF operation that meets these requirements, AWS WAF + WafCharm was the best choice. Since WafCharm runs on AWS WAF, it is easy to integrate with other AWS components, and the ability to seamlessly monitor and analyze WAF and other services is quite appealing. In addition, the low initial cost of the system was also a big attraction, and since we were able to verify the system without incurring any initial costs, the implementation proceeded smoothly.

Classi will continue to use a combination of automated rule sets and custom rules for flexible rule management and we continue to have high expectations from WafCharm and its provider, Cyber Security Cloud, in the future.
