We would like to introduce a case study on the implementation of the "Cloudmark Security Platform for Email" at Ricoh Company, Ltd. The company had been in a black box state, completely unaware of what emails were being sent, how many, and from where to where. To achieve security measures, promote digital transformation (DX), and improve operational efficiency, it was urgent to visualize and reconstruct the email system. To break this situation, they standardized email software while implementing the "Cloudmark Security Platform for Email" as an email gateway. This enabled real-time visualization and control of traffic, resulting in significant improvements in security through finely tunable policies. [Challenges Before Implementation] - The email system was in a black box state, posing significant security risks. - Different organizations operated on varying email systems and standards, leading to issues such as garbled text and undelivered messages. *For more details, please refer to the PDF document or feel free to contact us.*

We would like to introduce a case study of the implementation of "DMARC/25 Analyze" at BANDAI SPIRITS Co., Ltd. In recent times, as security incidents have been on the rise, the company had been relying on manual checks and reports to confirm the presence of phishing emails impersonating their e-commerce site "Premium Bandai." With the introduction of "DMARC/25 Analyze," the company was able to easily quantify the status of their phishing email countermeasures, enabling proactive detection. This also significantly reduced the effort they had previously invested. [Challenges Before Implementation] ■ They were considering how to establish clearer and more effective measures to confirm the presence of phishing emails, which had been unclear. *For more details, please refer to the PDF document or feel free to contact us.*

We would like to introduce a case study on the implementation of "DMARC/25" at Techouse Inc. In their operations, the company exchanges numerous emails related to job postings, recruitment, and applications with various clients. The security risk of phishing emails is very high, necessitating the proper implementation of email domain authentication technology. With the introduction of "DMARC/25," the previously opaque email sending routes have been corrected. This is expected to lead to an improvement in the reputation score and a reduction in email delivery issues. [Challenges Before Implementation] ■ Due to the exchange of emails related to job postings, recruitment, and applications with clients, there is a high risk of phishing emails, making the implementation of email domain authentication necessary. ■ Numerous emails are sent from multiple domains, and there are several email sending infrastructures, resulting in an unclear application status of SPF and DKIM. ■ Email delivery issues, believed to be caused by a decrease in reputation score, have occurred, necessitating the implementation of email domain authentication technology to improve the reputation score. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the implementation of "RSTOR" at KADOKAWA Connected Inc. The company's video community service "Niconico," one of the largest in Japan, contains a vast number of files in its object storage. There were many Read/Write operations for small-sized data, and during these times, the concentration of hundreds of millions of objects led to issues such as system failures and inability to operate. In response, the company replaced its existing system with the high-speed cloud storage "RSTOR." With the introduction of "RSTOR," they were able to configure an object storage solution that matched their service, reducing operational unavailability and achieving performance well above expectations. [Challenges Before Implementation] ■ The existing system experienced system failures and became inoperable during times of object concentration or bulk deletion of large amounts of data. ■ The existence of nearly 100 million objects resulted in enormous costs. ■ The current system required routine tasks to maintain performance, which also incurred costs. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study on the implementation of "DMARC/25" at A2 Corporation. The company had previously set up SPF records as a measure against spoofed emails, but they were unable to ascertain the actual number of spoofed emails that failed authentication. In order to confirm the status of their measures against spoofed emails, they chose our "DMARC/25," which offers complete support in Japanese, as many DMARC analysis services are foreign products. By implementing "DMARC/25," they were able to understand the status of SPF authentication and identify issues related to third-party signatures and email forwarding. This has been useful for their future measures against spoofed emails. [Challenges Before Implementation] ■ Although they believed that the SPF record settings should have mitigated spam emails with spoofed sender addresses, they did not know how many emails were actually failing authentication. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the implementation of "RSTOR" at Kids Star Co., Ltd. The company, which operates a digital content business for families, has been working to increase app users in line with its business expansion, but has been troubled by the rising costs of CDN that have increased proportionally. One day, after referring to the implementation case of "RSTOR" by another company, they decided to implement it due to its clear pricing structure that leads to cost reduction and the good performance observed in the actual test environment. After the implementation, they provided users with stable content delivery unchanged from before, while achieving the expected reduction in CDN costs. [Challenges Before Implementation] ■ Struggling with the rising CDN costs that increase in proportion to the expansion of app user utilization ■ Although CloudFront was addressed with Reserved Capacity, there was no fundamental solution ■ Having allocated resources to front-end development, they missed the timing to transition to a new architecture for the back-end (AWS) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the implementation of "Cloudmark Authority" at Nifty Corporation. The company had been using products from other vendors for spam email countermeasures, but it became quite burdensome in terms of costs for both the products and infrastructure, as it required operation on a server cluster of several dozen machines. On the other hand, the company had previously implemented the MTA software "Cloudmark Security Platform," and since it was possible to add the email security solution "Cloudmark Authority" as an add-on, and the associated server operation costs and product costs matched their expectations, they decided to proceed with the implementation. After the implementation, not only did they achieve the expected spam detection, but they also eliminated the need for several dozen servers that were necessary for operating other vendor products, resulting in significant infrastructure cost savings. [Challenges Before Implementation] ■ They were operating several dozen servers with products from other vendors for spam email countermeasures, which became a burden in terms of product and infrastructure costs. *For more details, please refer to the PDF document or feel free to contact us.
