Sigstore Announces General Availability for Rekor and Fulcio

Sigstore is excited to announce general availability (GA) for the Rekor transparency log and Fulcio certificate authority public benefit services! The community has been working hard all year to accomplish this milestone, and we are thrilled that open source communities can now confidently rely on Sigstore for production grade stable services for artifact signing and verification. While the Sigstore community has maintained a public instance since early 2021, the services were operated on a best-effort basis and maintainers periodically had to make breaking changes or reset data.

Sigstore Proves That Effective Supply Chain Security Doesn’t Have to Hurt

This is a Sigstore case study contributed by Brandon Gulla, CTO at Rancher Government Solutions Traditionally, everyone in IT assumed good security had to hurt a little bit. If it didn’t hurt, security wasn’t strong enough. But computing trends in software supply chains have shifted in recent years, moving toward centralized development and software factories. When you have that common infrastructure throughout the organization, you can isolate a lot of that pain within the process — without too much developer interaction and disruption.
