Customers Mail Cloud, a Cloud-based Email Delivery Service, Achieves AWS Certification Milestone

HENNGE K.K. (Headquarters: Shibuya-ku, Tokyo; Representative Director and CEO: Kazuhiro Ogura) announces that its cloud-based email delivery service, “Customers Mail Cloud,” has passed the AWS Foundational Technical Review (FTR) and has been certified as AWS Qualified Software.

Customers Mail Cloud demonstrates its objective evaluation as a secure and reliable solution by passing the FTR examination. The certification also shows that HENNGE has knowledgeable engineers and a trustworthy operational foundation to pass the FTR.

Phishing scams utilizing spoofed emails impersonating corporate domains are a growing concern in email security. To combat this, major providers like Microsoft and Google are strongly urging companies to implement robust email authentication technologies, including DMARC (*1). As the need for companies to reliably deliver critical emails such as one-time passwords and transaction confirmations increases, advanced technology and specialized knowledge are essential.

Customers Mail Cloud addresses these challenges by offering a DMARC report visualization tool alongside an email relay server that adheres to sender guidelines like SPF, DKIM, and TLS encryption. This service has successfully passed the FTR review. Through Customers Mail Cloud, companies can easily comply with AWS best practices and the latest email security standards, ensuring a high and secure email deliverability rate.

The following three HENNGE services have passed the FTR review and are AWS Certified Software:

  • HENNGE Email DLP, a solution for preventing misdirected emails
  • HENNGE One Identity Edition, an IDaaS (*2)
  • HENNGE Secure Transfer, a large-size file transfer solution

HENNGE will continue to develop and provide secure and reliable solutions that earn the trust of users and partner companies.
