Shorter TLS series
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.
Why join the shorter TLS series?
199-day maximum certificate validity changes everything. Go a millisecond over, into 200 days, and you’re facing revocation, or worse, an outage.
Shorter validity
TLS lifecycles are now brutally short, and outages hit instantly if you're late.
Manual oversight
Spreadsheets and reminders can't keep up with faster expirations.
Routine disruptions
Midnight emergencies and sudden audits are now the norm.
What you'll learn
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.
01

An interactive session with Nick France and Brendan Bonner.
Maximum certificate lifespans have been set to 199 days. Join us for an interactive session to find out what this means for businesses. Whether you're an executive hoping to gain an understanding of the new CA/Browser Forum rules, or whether you're a tech admin preparing your organization for the shortening lifecycles - join us to ask your questions and also see certificate automation in action. We'll have technical, compliance and sales exports on hand to guide you through the industry shift.
The official start of the shorter certificate lifespan mandate happened on March 15, 2026, with the first stepdown to 199-day (~6-month) maximum certificate terms. You may not have felt this change immediately, but in about 6 months time, your organization will start to see double the amount of renewals and expirations. Our team of experts will walk you through our 5-step, practical toolkit that aligns your team and positions you to adopt an automated system as certificate lifespans continue to decrease. Learn how to reduce manual effort, centralize visibility and prevent expiration failures.
4pm EST
An interactive session with Tim Callan and Brendan.

Shorter certificate lifespans require automation. But what might seem like an expensive, time-draining endeavor, is actually the push your organization needs to modernize and become crypto-agile. In this webinar, our team will cover how automating your certificate management strengthens your leadership, delivers ROI, keeps your compliance tight, and reduces your operational and reputational risk.

Dustin Moody of the National Institute of Standards and Technology (NIST) delivers a comprehensive look at the state of post-quantum cryptography (PQC) and what comes next. This session will cover NIST’s PQC standards work, the standards already published, and ongoing and future efforts, including Falcon, HQC, and the post-quantum “onramp.” Attendees will gain insight into migration timelines, the NCCoE Migration to PQC project, and considerations shaping the U.S. government’s transition to quantum-resistant cryptography. The session will conclude with a practical enterprise lens, connecting NIST’s guidance to the operational realities of automation, crypto-agility, and the critical role of certificate lifecycle management in executing a successful PQC transition with Sectigo's Tim Callan.

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:
- March 15, 2026: Maximum certificate lifespan reduced to 200 days
- March 15, 2027: Further reduction to 100 days
- March 15, 2029: Final enforcement of the 47-day maximum lifespan
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:
- Avoid unexpected expiration due to timing or deployment delays
- Ensure compliance with industry requirements
- Reduce the risk of service outages
- Maintain alignment with automation best practices
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.
