Three DV and OV products from a fast DV certificate to a business-verified OV with a $250,000 warranty. Need Extended Validation? See Enterprise EV.

Key benefits

Fast DV issuance

Basic DV certificates are typically issued within minutes of domain validation completion: fastest path to production TLS for new sites and rapidly provisioned infrastructure.

ACME-compatible

Automate issuance and renewal via RFC 8555 ACME with HTTP-01 or DNS-01 challenges. Works with cert-manager, Caddy, Traefik, Certbot, acme.sh, and every ACME-compatible client.

Full TLS encryption

AES-256 encryption of all traffic between browser and server: the modern cipher standard required by PCI DSS v4, HIPAA safeguards, and government procurement policies.

DV and OV validation

Three validation levels: DV (Domain Validation) for fastest issuance, OV (Organization Validation) for verified business identity in certificate details, and OV with subdomain coverage for broader single-certificate protection.

Warranty up to $250,000

Premium OV carries a $250,000 warranty: indemnification for relying parties against financial loss from CA issuance errors, far exceeding the coverage offered by free automated CAs.

Precisely scoped protection for one domain or subdomain

A Single Domain TLS/SSL certificate secures one specific fully qualified domain name (FQDN). Three DV/OV sub-products cover everyday use cases. For Extended Validation, see Enterprise EV.
