The fastest way to get S/MIME — email-address validation, issued in minutes.
A Basic S/MIME certificate validates your email address and lets you sign and encrypt email messages. Recipients of signed messages see a verified-sender indicator in their mail client. Issued in minutes, it's the most accessible way to add S/MIME to your personal or professional email — no identity documents required.
A Basic S/MIME certificate is the entry-level tier of S/MIME (Secure/Multipurpose Internet Mail Extensions). It validates your email address — proving you control the inbox — and then issues a certificate that lets you digitally sign and encrypt email messages. Signed messages display a verified-sender indicator in compatible mail clients. Encrypted messages are readable only by the intended recipient. No identity documents are required; validation happens automatically through the email address itself.
