Red Sift invites you to their event

How to adapt to shorter certificate lifecycles and PKI changes with Let’s Encrypt and Red Sift

About this event

The TLS certificate landscape is undergoing its most significant structural shift in a decade. We’re bringing together experts at the heart of this change to offer security engineers, DevOps teams, and IT leaders practical guidance on automation strategies, ACME tooling, and advice on building a complete certificate inventory across public and private infrastructure.

With Apple's enforcement of 200-day certificate lifespans already live, Let's Encrypt issuing 45-day certificates for early adopters, and the broader industry converging on a future powered by automation, the PKI ecosystem is evolving. In this session, co-hosted by Let’s Encrypt and Red Sift, we'll unpack the forces driving certificate lifecycle compression from CA/Browser Forum policy to the post-quantum transition.

Whether you're managing a handful or thousands of internal certificates, this session will leave you with a clear framework for navigating what's happening, why it matters, and how to prepare for the months and years ahead.
