Up until now, Macnica had adopted a method (PPAP) in which files attached to emails are encrypted using ZIP and the password is sent separately (PPAP), but we have decided to abolish this method as we believe it is not effective from a security perspective. did.

<Background of abolition>
Attaching a password-protected encrypted ZIP file increases security risks such as malware.
We will abolish PPAP to reduce security risks not only for our company but also for our business partners.
In the future, we will change the method to send the attached file as it is.
