Sectigo Completes Entrust Certificate Migration Following Acquisition

Sectigo says it has migrated more than a half-million certificates.

Sectigo, a provider of digital certificate lifestyle management solutions, recently said that it had successfully completed migrating Entrust Certificate Services (ECS) customers to its Sectigo Certificate Manager (SCM) platform.

In a news release, Sectigo called the migration the “largest-ever automated migration of public certificate infrastructure,” saying it had migrated more than a half-million certificates.

IT leaders have recently been hit with several shakeups in the public certificate space involving certificate authorities (CAs).

Last year, Google announced that it would no longer trust Entrust TLS certificates as of Nov. 1, 2024, attributing the move to security concerns with the certificate authority.

“Over the past several years, publicly disclosed incident reports highlighted a pattern of concerning behaviors by Entrust,” Google said in a blog post at the time and that those reports “eroded confidence in their competence, reliability and integrity as a publicly trusted CA Owner.”

The announcement forced Entrust-using organizations to look for an alternative CAs almost immediately, knowing that wasting time could mean Chrome internet connection chaos across the organization and an erosion of public trust in the organization’s own internet apps and presence.

Sectigo ended up acquiring Entrust in January 2025.

In April, The CA/Browser (CA/B) Forum decided to reduce the maximum validity term of SSL/TLS certificates to 47 days by 2029.

Currently, the maximum lifetime for a TLS certificate is 398 days and will continue to remain so until March 15, 2026, according to Digicert. TLS certificate lifetime will reduce to 200 days as of March 15, 2026, and then to 100 days as of March 15, 2027.

The migration was a “fully automated experience at unprecedented scale,” said Mark Bilgre, chief product and engineering officer at Sectigo, in a news release.

“We made a promise to Entrust customers that Sectigo would deliver a seamless migration. Today, I am proud to say we delivered on that promise,” said Kevin Weiss, CEO of Sectigo, in a news release. “This was the first migration of its kind and scale in our industry, and it sets a new benchmark for digital trust transitions. It was made possible by the extraordinary work of our engineering, sales and support teams who ensured customers felt confident every step of the way. The positive feedback that we have received confirms that we have exceeded expectations.”
