The certificate world has changed. So must you.
Every Tuesday from March 17, 2026
Virtual | 11:00 AM EST
Certificates used to hum quietly in the background. Now lifespans are shrinking, machine identities are multiplying, and compliance rules arrive faster than ever. Everything has sped up, except how most organizations manage certificates.
Miss one renewal and everything stops.
Miss the wrong one and it’s a headline.
Shorter lifespans. Machine identity sprawl. Rising renewal volume. And a quantum shift that’s coming whether teams acknowledge it or not.
The race only gets faster from here.
The effectively 199-day maximum certificate validity changes everything. Go a millisecond over 200 days, and you’re facing an outage.
TLS lifecycles are now brutally short, and outages hit instantly if you're late.
Spreadsheets and reminders can't keep up with faster expirations.
Midnight emergencies and sudden audits are now the norm.
This series exists to help you get there.
Whether you’re just beginning your automation journey or already scaling certificate lifecycle management, this series delivers clarity, tools, and confidence for what comes next.
Understand the new certificate landscape, shrinking lifespans, and what’s coming next.
Practical steps to automate discovery, issuance, renewal, and governance.
Real-world stories of transformation, risk reduction, and operational scale.
See certificate automation in action as a predictable, scalable, and secure tool.
Each session will run for 1 hour including a 10 minute Q&A with presenters at the end.
Sectigo helps organizations move from fragile, manual certificate management to automated, governed, and crypto-agile trust at scale, across public and private PKI, every environment, and every identity.
Shorter lifespans aren’t coming. They’re here.
Join the Shorter TLS Series for Tuesdays of insight, action, and future-proof strategies.
This series is designed for security and IT leaders, including CISOs, PKI administrators, enterprise architects, DevSecOps teams, and IT operations professionals responsible for managing digital trust, uptime, and compliance in their organizations.
The passage of the CA/Browser Forum ballot to reduce the maximum certificate lifespan represents a natural and anticipated progression in the industry’s ongoing effort to enhance security and streamline certificate management. This move, while significant, is neither surprising nor disruptive to those who have been following the industry’s trajectory over the past decade. Rather, it is a continuation of a well-documented trend toward shorter certificate lifetimes - a trend that has consistently aligned with the need for improved security, crypto-agility, and automation.
The first stepdown will be in March of 2026, shortening certificate lifespans to 200 days. The dates are as follows:
Not exactly. While it’s commonly referred to as a “200-day” certificate lifespan, the actual maximum validity is 199 days due to how certificate validity periods are calculated under the mandate adopted by the CA/Browser Forum. However, Sectigo recommends renewing your certificates every 180 days (about six months). Renewing at 180 days provides a safety buffer to:
In short, although the technical maximum is 199 days, planning for 180-day renewals (effectively six months) is the recommended and safer operational approach.
This is a series of interactive webinars that combine high-level thought leadership with practical, hands-on workshops. You’ll walk away not just informed, but equipped with a personalized Shorter TLS Plan you can act on immediately.
You’ll gain insight into the operational and security risks caused by certificate lifecycle gaps, hear from industry experts and peers, and receive a step-by-step plan to proactively manage your certificate inventory and expiration timelines.
