July 2026 - ACME Profiles Update

Google Trust Services has added support for the ACME Profiles draft specification and introduced our first profile for TLS certificates.

This enables customers to use ACME profiles for their certificate requests. See the current list of GTS profiles.

The minimal profile makes size-optimized certificate chains readily selectable by customers who want an optimized leaf certificate and ECDSA chain.

We recommend that ACME clients support Profiles if they have not already done so.
