[Cipher suites](/ssl/edge-certificates/additional-options/cipher-suites/) are a combination of ciphers used to negotiate security settings during the [SSL/TLS handshake](https://www.cloudflare.com/learning/ssl/what-happens-in-a-tls-handshake/). As a SaaS provider, you can [specify configurations for cipher suites](#cipher-suites) on your zone as a whole and cipher suites on individual custom hostnames via the API.


:::caution
When you [issue a custom hostname certificate](/cloudflare-for-platforms/cloudflare-for-saas/security/certificate-management/issue-and-validate/) with wildcards enabled, any cipher suites or Minimum TLS settings applied to that hostname will only apply to the direct hostname.

However, if you want to update the Minimum TLS settings for all wildcard hostnames, you can change Minimum TLS version at the [zone level](/ssl/edge-certificates/additional-options/minimum-tls/).

Once you have [added a custom hostname](/cloudflare-for-platforms/cloudflare-for-saas/start/getting-started/), you can enable mTLS by using Cloudflare Access. Go to [Cloudflare Zero Trust](https://one.dash.cloudflare.com/) and [add mTLS authentication](/cloudflare-one/identity/devices/access-integrations/mutual-tls-authentication/) with a few clicks.

In this case, when the certificate with the closest expiration date is renewed, it will then become the one with the latest expiration date and get presented.
