[Case Study] Techouse Inc.

A case where measures against impersonation were visualized and the high-risk email environment was collectively corrected!

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.
