• Security Assessment

We would like to introduce a case study of the implementation of the "Cloudmark Security Platform for Email" at Ricoh Company, Ltd. The company was in a black box state, completely unaware of what emails were flowing, in what quantities, and from where to where. To achieve security measures, promote digital transformation (DX), and improve operational efficiency, it was urgent to visualize and restructure the email system. To break this situation, the "Cloudmark Security Platform for Email" was introduced as an email gateway while standardizing the email software specifications. 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 email systems and standards, leading to issues such as garbled text and undelivered emails. *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 Analyze" at BANDAI SPIRITS Co., Ltd. In recent times, as security incidents have been increasing, the company had been relying solely on manual checks based on reports to confirm the existence 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 phishing email countermeasures and actively detect such threats. This also significantly reduced the effort previously required. [Challenges Before Implementation] ■ The company was looking for a clearer and more robust way to confirm the existence 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" for 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 introduction of proper email domain authentication technology. With the implementation 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 failures. [Challenges Before Implementation] ■ Due to the exchange of emails related to job postings, recruitment, and applications with clients, the risk of phishing emails is high, making the introduction of email domain authentication necessary. ■ Numerous emails are sent from multiple domains, and there are multiple infrastructures for email sending, making the application status of SPF and DKIM unclear. ■ Email delivery failures, believed to be caused by a decline in reputation scores, have occurred, necessitating the introduction 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.

• Data Backup

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, has a vast amount of files stored in its object storage. There were many Read/Write operations for small-sized data, and during these times, the concentration of objects in the hundreds of millions 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 that matched their service, reducing operational downtime and achieving performance well above expectations. 【Challenges Before Implementation】 ■ The current 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 required 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 of 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 measures against spoofed emails, they chose our "DMARC/25," which offers complete support in Japanese, over many overseas 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 spoofed spam emails, 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 develops digital content for families, has been working to increase the number of app users in line with its business expansion. However, it has been struggling with the rising costs of CDN that have increased in proportion to this growth. One day, after referring to the implementation case of "RSTOR" at another company, they decided to adopt it due to its transparent pricing structure that leads to cost reduction and the good performance observed in the actual test environment. After the implementation, they were able to provide users with stable content delivery, unchanged from before, while achieving the anticipated reduction in CDN costs. 【Challenges Before Implementation】 ■ Struggling with the increasing CDN costs that rise in proportion to the expansion of app user utilization ■ Although CloudFront was addressed with Reserved Capacity, there was no fundamental solution ■ Having allocated resources primarily 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 was necessary to operate on a scale of dozens of servers. 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 dozens of servers that were required for the operation of other products, resulting in significant infrastructure cost reductions. [Challenges Before Implementation] ■ They were operating a group of dozens of servers with products from other vendors for spam email countermeasures, which was a burden in terms of product and infrastructure costs. *For more details, please refer to the PDF document or feel free to contact us.
