Google Trust Services (Free public CA) review 2026

Google's own certificate authority, free over ACME — the natural choice if your infrastructure already lives in Google Cloud

Is the Google Trust Services Worth It?

Best free option on Google Cloud. On Google Cloud this is the path of least resistance and costs nothing. Anywhere else, Let's Encrypt does the same thing without a cloud account.

Google Trust Services Pros & Cons

Pros
  • Free, including wildcards, from one of the most widely trusted roots
  • Standard ACME, so Certbot and friends work unchanged
  • Automatic on Google Cloud Load Balancing and App Engine
  • Generous rate limits for larger estates
Cons
  • Requires a Google Cloud project and API setup — more friction than Let's Encrypt
  • DV only, no warranty, no support desk
  • Little reason to choose it outside the Google ecosystem

Why it scored 7.7

On Google Cloud this is the path of least resistance and costs nothing. Anywhere else, Let's Encrypt does the same thing without a cloud account.

Where it loses

Setup friction off Google Cloud.

Still the right pick for

Google Cloud infrastructure.
