12SSL is the official SSL certificate and automation website operated by Kyuudai Co., Ltd. in Japan.
We provide trusted SSL certificate products for websites, applications, public IP addresses, customer portals, hosting environments, and online transactions. Our product lineup includes Standard SSL certificates, AutoSSL subscription products, Public IP SSL, Multi-Domain SSL, Wildcard SSL, and related HTTPS deployment guidance.
What We Do
12SSL supplies SSL certificates from globally recognized Certificate Authorities, including Sectigo and other trusted CA brands.
Our goal is simple: make reliable HTTPS protection easier to purchase, deploy, and maintain.
Product Focus
Standard SSL Certificates
Standard SSL remains available for customers who need familiar certificate products, specific CA options, Public IP SSL, SAN coverage, Wildcard coverage, or manual certificate issuance and deployment workflows.
AutoSSL
AutoSSL is our automation-focused product direction. It helps customers reduce repeated certificate reissuance and installation work by automating certificate issuance, deployment, and renewal throughout the active subscription.
Public IP SSL
Public IP SSL is designed for infrastructure that needs HTTPS on a public IP address instead of a domain name. It uses IP control validation and is compatible with major browsers, operating systems, and mobile devices.
Our Values
- Excellence: we aim to provide reliable SSL products and clear support.
- Integrity: we operate with transparency and legal compliance.
- Collaboration: we turn real customer questions into practical documentation.
