Sectigo has successfully completed the largest migration of public certificate infrastructure in history, transitioning over half a million SSL/TLS, S/MIME, and code signing certificates from Entrust to Sectigo Certificate Manager. This milestone sets a new standard for digital trust transitions, giving customers a secure, automated, and future-ready CLM platform.

In February, I shared our commitment to thousands of Entrust customers and partners: that Sectigo would deliver a simple, secure and future-ready migration to our certificate lifecycle management (CLM) platform. I’m proud to say that we’ve delivered on that promise.

Sectigo has successfully completed the largest and most technically sophisticated migration of public certificate infrastructure in industry history. More than half a million certificates – spanning SSL/TLS, S/MIME, and code signing – have been transitioned from Entrust Certificate Services to Sectigo Certificate Manager (SCM). But this wasn’t just a migration, it was a milestone rooted in trust, driven by strategy and executed with precision.

Engineering the future of digital trust

We know that trust isn’t just built on technology and innovation, it’s built on integrity and transparency.

That belief shaped every decision we made throughout the migration. From the beginning, our customer-first mindset ensured our every decision reflected our commitment to long-term customer success.

That’s why we gave Entrust customers early access to SCM, allowing them to explore the platform without disrupting their production environments. It was the test drive before the journey began and a tangible example of how we turned principle into practice.

We also recognized that no two migrations would be alike. So, we took the time to understand each customer’s requirements and empowered them to migrate on their own timeline, giving them full control over their transition. This wasn’t a one-size-fits-all approach; it was a tailored experience designed to meet each organization’s unique needs. Whether customers chose our guided migration workflows, utilized our free professional services/support, or leveraged our simple migration developed in partnership with Entrust, every path was designed to minimize disruption and maximize control.

Behind the scenes, our engineering teams built a powerful, automated migration framework that included:

• In-app, guided migration workflows for every customer and partner

• Extensive pre-validation automation to eliminate issuance delays

• Real-time user provisioning and certificate inventory synchronization

• Custom feature parity work to ensure continuity and control

• Seamless partner migration into our new Sectigo Partner Platform

These innovations weren’t simply created to move certificates from point A to point B. They were about unlocking new possibilities for transitioning customers and partners. With shrinking certificate lifespans and the looming impact of post-quantum cryptography (PQC), organizations need the right tools. They need agility. They need foresight. Sectigo Certificate Manager delivers all three… and more.

A new standard for digital trust transitions

The migration set a new benchmark for scale, speed and precision in our industry. It was made possible by the extraordinary work of our engineers, developers, sales and support teams, each of whom played an important role in keeping customers confident throughout the process.

This milestone wouldn’t have been possible without the close collaboration between Sectigo and Entrust’s engineering teams. Both teams played a critical role in ensuring a smooth and coordinated transition. We’re grateful for the Entrust partnership and proud of what we accomplished together. We extend our sincere thanks.

At Sectigo, we continue to push the boundaries of what’s possible—and redefine what digital trust looks like. Former Entrust public certificate customers and partners now have access to a cloud-native, CA-agnostic CLM platform that automates every aspect of certificate management.

This migration was more than an incredible engineering feat and technical achievement, it was a promise kept. And it’s just the beginning.
