Case Study: Helping Customers Open Emails with Confidence. How FOLIO Embraces BIMI as "Proactive Security"

FOLIO Corporation is an online securities service provider operating in Japan's financial industry.

With guidelines from Japan's Financial Services Agency and the Japan Securities Dealers Association driving industry-wide efforts to strengthen email security, FOLIO took action. Following Google's Email Sender Guidelines update in 2024, the company implemented DMARC and progressed to a full "reject" policy by 2025.

Yet their motivation went beyond compliance. In an era where customers struggle to tell legitimate emails from fraudulent ones — and many simply leave suspicious messages unopened — FOLIO's core goal was clear: give customers the confidence to open their emails. That conviction led them to adopt BIMI and a Verified Mark Certificate (VMC).

By displaying their logo directly in recipients' inboxes, FOLIO not only signals authenticity at a glance, but also drives higher open rates and reinforces brand recognition — turning security into a marketing asset. Their approach stands as a model of "proactive security," achieved through close collaboration between security and business teams.
