Approach and System

Approach to Information Security

We develop and provide cloud-based business chat services that streamline and revitalize business to our customers, exceeding 386,000 companies^*1 with 1,053,000 DAUs^*2. We are entrusted with important information assets and confidential information by our customers.
We have positioned information security as our most important management issue as the reliable protection of this information is a prerequisite for business continuity. We established our "Basic Policy on Information Security" in January 2013 and are working to ensure information security throughout the company.

Information Security Structure

We have established an information security structure headed by our CEO. The CSE Department^*1 of the Corporate Division manages information security for our entire Group's information systems, and the Product Security Department of the Product Division manages information security for the products and services we develop.
We have also appointed CISSP^*2 certified personnel who possess advanced expertise in information security to respond to the changing security environment.

kubell's Main Initiatives

Initiatives to Ensure Information Security

Our initiatives to ensure information security are as follows.

1) Acquisition of International Certifications for Information Security

We operate our systems in accordance with strict security standards. All operations of kubell Co., Ltd. and kubell storage Co., Ltd. have been audited by third party organizations. Through this process, we have acquired the ISO/IEC 27001:2013 (JIS Q 27001:2014)*1 international certification standard for information security; ISO/IEC 27017:2015*2 international certification standard applicable to the provision and use of cloud services; and the ISO/IEC 27701:2019 international certification standard for the appropriate protection of personal and related privacy information.

*1 ISO/IEC 27001:2013 (JIS Q 27001:2014): International standard for Information Security Management Systems (ISMS)
*2 ISO/IEC 27017:2015: Guideline standard for information security management measures for cloud services

2) Measures Against External Attacks

The environment surrounding information security is changing rapidly. As a result, the risk of information leakage is rising each year due to increasingly sophisticated cyber-attacks and other external attacks. To respond to this risk, we are working on security measures from both product development and corporate management perspectives.

In terms of product development, we are implementing measures such as preventing and blocking unauthorized access, introducing WAF*, managing vulnerabilities to evaluate and confirm those that exist in middleware and libraries used for development, conducting security training to ensure secure development, and carrying out periodic assessments using an external security specialist company. We have also established a Product Security Department dedicated to product security measures, and have established and operate a security consultation desk and security risk reporting form where employees can consult and report on information security. Furthermore, we have implemented a "Bug Bounty Program," an institutionalized system for the discovery of vulnerabilities by external bug hunters with high technical skills that offers rewards upon discovery. We are also continuously working on developing secure products through measures such as regularly implementing risk management inventories, in which critical risks are evaluated and identified from risk incidents identified through security risk reporting forms and other means, and countermeasures are discussed.
In terms of corporate security, we are enhancing security measures at endpoints, such as the end information devices of executives and employees.

*WAF: Web Application Firewall, a security measure to protect web applications from unauthorized access, such as by blocking attacks

Primary Measures Against External Attacks

3) Measures to Prevent Internal Information Leaks

When developing products, we conduct reviews to prevent information leaks during development and have built systems whereby only the minimum necessary personnel can access the minimum necessary information to prevent unauthorized access and tempering. In addition, we carefully store important data including service access, usage, and data communication history (logs) for service maintenance and security measures, building and operating systems to monitor access to information systems. We regularly check whether these systems are being operated properly and conduct internal audits. We also take measures to prevent information leakage from those who have left the company.
In terms of ensuring corporate security, we provide information security education to all employees, set minimum access privileges for important information, manage system accounts, and store system logs. We also centrally manage the security settings of laptop computers and other terminal devices, and have introduced MDM*, which deletes all data in the event of loss, to prevent information leakage. In addition, we manage the status of the personal information entrusted to third parties and conduct security checks.

*MDM: A method to manage system settings and other aspects of terminal devices such as smartphones and laptops used for business in an integrated and efficient manner. It also refers to the software and information systems that enable this.

Primary Measures Against Internal Information Leaks

4) Other Initiatives to Improve Information Security

As the risk of information leaks increases, there are limits to the measures that can be taken by individual companies. Because of this, in October 2022, we established the "SaaS Security Community" in collaboration with SaaS providers as a forum for companies that develop and operate SaaS services for BtoB to exchange information on security measures. We did this to strengthen security measures through collaboration with companies that offer similar services. The community, currently consisting of 12 companies, encourages the exchange of information and vulnerability assessments to strengthen security measures.
