Fastly’s certification authority

Certainly: trusted, secure, reliable and compliant

Certainly is Fastly’s publicly-trusted Certification Authority (CA), giving Fastly customers the option to create and manage certificates issued by Certainly to secure any website or API endpoint served by Fastly.

Simplify certificate management by automatically creating new TLS certificates to certify your websites and servers are secure. Certainly certificates offer a high level of trust and reliability, and are fully supported by Fastly’s support team.

With Certainly, you can rest easy knowing Fastly is in control of all of your certificate management needs.

Why Certainly?

• Tighter security and reduced risk: A 30-day validity period, coupled with automation, achieves a higher level of security, plus Certainly is not available on the public internet which provides even more protection for your certificates.
• Simplified certificate management: Reduce the pain of managing certificates and renewals, even for hundreds of thousands of domains, with a dedicated, publicly trusted, certification authority.
• More reliable, better support: Put trust in Fastly’s distributed, global delivery network for TLS certificates and remove the dependency on third-party providers. Fastly is in control of resolving any issues, from provisioning to renewing.

Detailed information

Legal documents, CA certificates, audits and problem reporting

Supported clients: Certainly certificates are trusted by most browsers, operating systems, and devices released since 2010. Certainly certificates inherit trust from an older trusted root certificate named the “Starfield Root Certificate Authority - G2". The Starfield root was created in 2009 and is included in the great majority of root stores released since then. This includes Apple iOS 4.1 and higher, and newer versions of Android Gingerbread 2.3 and later.
