# Universal SSL

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/ssl/edge-certificates/universal-ssl/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

By default, Cloudflare issues — and [renews](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/ssl/reference/certificate-validity-periods/#universal-ssl) — free, unshared, publicly trusted SSL certificates to all domains [added to](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/fundamentals/manage-domains/add-site/) and [activated on](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/dns/zone-setups/reference/domain-status/) Cloudflare.

On a [full setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/dns/zone-setups/full-setup/), Universal SSL certificates cover your root domain (for example, `example.com`) and first-level subdomains (for example, `www.example.com`). On a [partial (CNAME) setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/dns/zone-setups/partial-setup/), each proxied subdomain receives its own certificate regardless of depth. Cloudflare handles issuance, renewal, and deployment automatically.

For full setup zones that need coverage beyond first-level subdomains, use [Total TLS](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/ssl/edge-certificates/additional-options/total-tls/) or [advanced certificates](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/ssl/edge-certificates/advanced-certificate-manager/).

Universal certificates are [Domain Validated (DV)](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/ssl/concepts/#validation-level), which means the certificate authority verifies domain ownership but does not validate organization identity. For setup details, refer to [Enable Universal SSL](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/ssl/edge-certificates/universal-ssl/enable-universal-ssl/).

Note

Universal SSL certificates are issued after your domain is active on Cloudflare. If you need an SSL certificate before migrating traffic, or if you need to [customize cipher suites](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/ssl/edge-certificates/additional-options/cipher-suites/customize-cipher-suites/), use [Advanced](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/ssl/edge-certificates/advanced-certificate-manager/) or [Custom](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/ssl/edge-certificates/custom-certificates/) certificates.
