As certificate lifetimes shrink, the way organizations manage domain validation needs to evolve. Persistent DCV and expanded DNS connector support in Sectigo Certificate Manager are designed to make that transition manageable at any scale. 

X9 PKI is a shared private trust model for U.S. finance, not a public WebPKI replacement, with unique benefits and tradeoffs.

SCOTTSDALE, Ariz. – May 19, 2026 – Sectigo, a global leader in automated Certificate Lifecycle Management (CLM) and digital certificates , today announced a refreshed brand identity and corporate positioning centered on a clear vision: delivering Simplicity at Scale as digital trust becomes more complex, more distributed, and more operationally critical.

Sectigo simplifies certificate lifecycle management (CLM) with automation, visibility, and control to help organizations scale digital trust securely.

Recent announcements from Google and Cloudflare have declared new 2029 deadlines for full post quantum cryptography (PQC) migration. Bas Westerbaan explains the rationale behind Cloudflare's decision and discusses implications for other enterprises., asking "Are you a gambler?"

Repeat guest Bas Westerbaan of Cloudflare joins us to explore the role of Merkle Tree Certificates (MTCs) in private CA scenarios with an eye toward where they will be needed and where traditional PKI will be better suited.

The US-based X9 financial industry consortium has created a server certificate. We explain what X9 certificates are and suitable use cases for this certificate type.

Dustin Moody of NIST joins us to discuss Merkle Tree Certificates (MTCs) and the NIST position on them.

Repeat guest Bas Westerbaan of Cloudflare joins us to explain the PLANTS working group in IETF, which is driving standards around post quantum cryptography (PQC) and Merkle Tree Certificates (MTC). Bas explains the path to becoming a final standard, where we are in this process, and how you can get involved.

It's reasonable to believe that Merkle Tree Certificates (MTC) and traditional RSA will co-exist on the same servers for years, if not decades, during the transition to post quantum cryptography (PQC). Bas Westerbaan of Cloudflare joins us in this episode to explore the possibility of quantum downgrade attacks and what we can do about them.

We are joined by Dustin Moody of NIST to go over the current state of the various post quantum cryptography (PQC) contests, including upcoming FIPS standards for Falcon (FN-DSA) and HQC, other Round 4 algorithms, the digital signing algorithm (DSA) On Ramp, isogeny, and future cryptographic exploration.

A data breach can cost small businesses hundreds of thousands of dollars and permanently damage customer trust. This article breaks down the true financial, operational, and reputational impact of breaches—and how SMBs can prevent them.

Customer trust is the foundation of online success for small businesses. This article outlines practical, affordable ways SMBs can build credibility through secure websites, verified communications, consistent branding, and visible trust signals.

We are joined by Bas Westerbaan of Cloudflare to explain considerations and requirements for use of Merkle Tree Certificates (MTCs). This includes full adoption of TLS 1.3, offering PQC and RSA at the same time, the imperative value of automation, and running production MTC in 2027.

Private PKI powers machine identity management by automating certificates, improving security, and preventing outages at scale.

There are strong reasons to believe that the architecture of PQC TLS will take the form of Merkle Tree Certificates (MTC). Post quantum cryptography expert Bas Westerbaan of Cloudflare explains this new PKI architecture, how it works, and why we need it.

SCOTTSDALE, Ariz. — April 29, 2026 — Sectigo, a global leader in automated Certificate Lifecycle Management (CLM) and digital certificates, today announced its partnership with F5 to enhance CLM across the F5 Application Delivery and Security Platform (ADSP).
