## The honest comparison

[DigiCert](https://startwithidentity.com/vendors/pki/digicert/) and [Sectigo](https://startwithidentity.com/vendors/pki/sectigo/) are the same kind of vendor: a publicly trusted certificate authority that also sells the [certificate lifecycle](https://startwithidentity.com/glossary/certificate-lifecycle/) management to go with it. Because each owns both the trust anchor and the management layer, either can be a single source for issuance and renewal, which is a different proposition from a certificate-authority-agnostic orchestration tool.

We grade them the same on seven of ten dimensions. DigiCert, founded in 2003 and privately held by Clearlake, TA, and Crosspoint, takes lifecycle and provisioning and support and ecosystem, and holds the higher overall score, 4.3 against 4.0. Sectigo, founded in 1998 and owned by GI Partners, takes pricing transparency. That is a fair summary of how the market itself reads them: DigiCert premium, Sectigo value.

Timing matters more than the gap. The CA/Browser Forum passed [ballot SC-081v3](https://cabforum.org/2025/04/11/ballot-sc081v3-introduce-schedule-of-reducing-validity-and-data-reuse-periods/) in April 2025, cutting the maximum lifetime of a publicly trusted TLS certificate to 200 days from March 2026, 100 days from March 2027, and 47 days from March 2029. Whichever of these you buy, the renewal cadence you are signing up for is automated or it is broken. Both support ACME, so ask about coverage across the systems you actually run rather than in principle. Sectigo's own weakness is at the top end, where its lifecycle depth trails the dedicated automation specialists on discovery and multi-certificate-authority orchestration.

## When DigiCert wins

- A certificate outage is a business outage, and you want the vendor we score higher on support and ecosystem answering the phone
- Code signing with hardware-backed keys, document signing, or IoT device identity at volume are in scope
- The fleet is large and mixed enough that DigiCert ONE's discovery and automation depth repays the setup effort
- Budget exists and you would rather pay for the premium option than defend a cheaper one after an incident

## When Sectigo wins

- Mid-market consolidation is the goal: public TLS and private PKI from one vendor without enterprise-tier pricing
- Cost per certificate is a genuine constraint and you want the option we score higher on pricing transparency
- The mix spans TLS, S/MIME, code signing, and document signing but not at hyperscale volume
- Certificate Manager covers your automation needs and you do not need the deepest crypto-agility tooling

## Pricing

DigiCert sells per certificate plus subscription and enterprise quotes for DigiCert ONE, and is not the cheap option at low volume. Sectigo sells per certificate and by subscription for Certificate Manager, and scores higher on pricing transparency. For plain public TLS at small scale, an ACME authority such as [Let's Encrypt](https://startwithidentity.com/vendors/pki/lets-encrypt/) is free and neither of these is warranted. The shortening lifetime schedule changes the arithmetic: a fleet that renewed once a year will renew several times a year by 2029, so price the renewals rather than the certificate. Model the whole fleet in the [TCO calculator](https://startwithidentity.com/tools/tco-calculator/).

## Verdict

Choose [DigiCert](https://startwithidentity.com/vendors/pki/digicert/) when scale, signing use cases, and support outweigh price. Choose [Sectigo](https://startwithidentity.com/vendors/pki/sectigo/) when you want a trusted authority with usable management at a mid-market price. If your real problem is orchestrating certificates across several issuers rather than buying them from one, that is a different product category: see [Keyfactor vs Venafi](https://startwithidentity.com/compare/keyfactor-vs-venafi/). For internal-only certificates, [Smallstep](https://startwithidentity.com/vendors/pki/smallstep/) is the lighter cloud-native option, and the process itself is covered in our [certificate lifecycle management guide](https://startwithidentity.com/guides/machine-identity/certificate-lifecycle-management-guide/).
