# Third-Party Security Certification

Thank you for using Kozutumi.

We are pleased to announce that Kozutumi, our secure file transfer platform, has obtained certification for the international standard ISO/IEC 27001 (Information Security Management System, or ISMS) as well as ISO/IEC 27017 (ISMS Cloud Security).

Together with the Privacy Mark—which we had previously acquired to demonstrate compliance with Japan's Act on the Protection of Personal Information—Kozutumi is now certified under the following three frameworks.

At Heartbeats, we consider information security to be one of our top priorities. We will continue to improve our services through the ongoing implementation and enhancement of ISMS practices.

We appreciate your continued support of Kozutumi.
