Press release

Mynavi adopted Cyber Security Cloud’s service for automation of AWS WAF operations “WafCharm”

Cyber Security Cloud, Inc. is pleased to announce that Mynavi Corporation has adopted its service for automation of AWS WAF operations "WafCharm".


■ Reasons for adoption
AWS WAF is a cloud-based web application firewall provided by AWS (Amazon Web Services), that helps protect web applications 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 tune rules on your own, and the need for expertise and resources to deal with new vulnerabilities.

While Mynavi had been using AWS WAF for some time, the company has decided to introduce WafCharm, provided by CSC, in order to solve these issues and strengthen cybersecurity. WafCharm is an automatic rule (signature) management service for AWS WAF using AI, and is the No. 1 *1 AWS WAF automation service in Japan with the largest no. of users for an AWS WAF automated operation service. It is equipped with an AI engine that uses machine learning to automatically apply the most appropriate WAF rules to AWS WAF, utilizing big data of more than 1.3 trillion data to automatically apply the most appropriate rules for each user. This frees users from web application security measures in an AWS environment, allowing users to focus more resources on their business.

■ Comment from a Mynavi Representative
As more and more services are adopting AWS as their platform, there is a need to maintain a certain level of security while reducing the operational burden. WafCharm is a service that automatically tunes AWS WAF signatures, so we decided to adopt it as it met our needs.
