Cyber Security Cloud, Inc. (Headquarters: Shinagawa-ku, Tokyo; President and CEO: Toshihiro Koike; hereinafter referred to as "the Company"), a global security manufacturer, is pleased to announce that it has entered into a business alliance with TWOSTONE Sync Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; President and CEO: Akimasa Miyazaki; hereinafter referred to as "TWOSTONE Sync"), a group company of TWOSTONE&Sons Co., Ltd. (hereinafter referred to as "TWOSTONE&Sons").

■ Background: Continuous security measures are necessary for the web and cloud environments that support our business.

① It is becoming increasingly important to continue taking countermeasures to prepare for attacks that exploit AI vulnerabilities and misuse them.

Websites and cloud-based services have become crucial business foundations. Meanwhile, the IPA (Information-technology Promotion Agency, Japan)'s "Top 10 Information Security Threats 2026" lists "cyber risks surrounding the use of AI" as the third-highest threat to organizations (a first-time selection), and "attacks exploiting system vulnerabilities" as the fourth-highest (*1). To prepare for these threats, it is important to understand the risks lurking in your own systems, such as vulnerabilities and misconfigurations, and to take countermeasures according to priority. It is necessary to continuously implement countermeasures that adapt to changing threats and system environments by resolving vulnerabilities through software updates and modifications, as well as by combining attack detection and blocking by WAFs and reviewing cloud environment settings.

② In addition to introducing the product, the challenge is to create a system that can continue to operate it.

Security measures are not complete simply by installing a product. After implementation, it is necessary to monitor the detection status of the WAF, adjust rules as needed, respond to new vulnerability information, and review settings in response to system changes. Meanwhile, there is a shortage of approximately 110,000 cybersecurity professionals in Japan (*2), and the lack of specialized personnel and time to dedicate to operation poses a challenge for companies in continuing to implement security measures.

Up until now, our company has been working to create systems that enable companies with limited security personnel to continue operations through automated WAF operation and fully managed services. This time, we have made security one of our key areas of focus and are collaborating with TWOSTONE Sync, which works closely with client companies from strategy planning to implementation and adoption. This will allow us to deliver our services from the security policy formulation stage and provide support until operations are firmly established.

■ Representative's Comment

Akira Miyazaki, Representative Director and CEO of TWOSTONE Sync Co., Ltd.

A strategy only becomes meaningful when it is implemented and generates profits. The same is true for security; simply outlining policies is not enough to protect your business. By combining Cybersecurity Cloud's proven products and operational expertise, we can help our clients establish their security not just as a plan, but as a solid system. We have made security one of our key areas of focus, and together we will work to ensure that our clients can move their businesses forward with peace of mind.

Through this partnership, we will combine our accumulated security technology and expertise with TWOSTONE Sync's ability to support customers from strategic planning to execution and implementation, and the TWOSTONE&Sons Group's IT talent network, to deliver continuous peace of mind to even more companies. By leveraging the strengths of both companies, we will support the creation of an environment where our customers can focus on business growth without being held back by security concerns.
