CERTIFICATE MANAGEMENT · TLM

All your certificates.
One clear view.

Discover your certificates, track their validity and manage renewals in one place. Less manual work. More control.

  • Certificate discovery and inventoryBring public and private certificates together, including certificates from different CAs.
  • Validity, access and policy oversightCentral visibility and alerts to plan the next action.
  • Automation for supported systemsIssue, renew and install certificates according to integrations and your environment.

Capabilities depend on licensing and integrations. Internal discovery may require a Sensor; server management may require an Agent.

DIGICERT · TLS/SSL

Trust starts with
your website connection.

TLS/SSL certificates encrypt communications and authenticate the server. We help match identity validation and domain coverage to your needs.

ANSWERS BEFORE YOU CHOOSE

Choose a certificate.
Understand what you get.

The key differences, with practical explanations to help you make the right choice.

How do website, email, code and document certificates differ?

TLS/SSL: Encrypt communications between the browser and server, and authenticate the server.
S/MIME: Sign email messages and, depending on configuration and available certificates, encrypt them.
Code Signing: Verify the software publisher’s identity and detect changes to a file after signing.
Document signing: Verify the signer’s identity and detect changes to a document after signing.

A certificate does not guarantee that a website or software is free from vulnerabilities or malicious content.

DV, OV and EV — what is the difference?

DV: Validates control of the domain.
OV: Validates domain control and verifies the organization’s identity.
EV: Verifies the organization’s identity under more extensive requirements.

The difference is the depth of identity validation, not encryption strength. EV does not guarantee a green address bar or a company name displayed in the browser.

FQDN, SAN and Wildcard — what does each cover?

FQDN: A specific, fully qualified domain name, such as shop.company.com.
SAN: Additional names listed in the same certificate.
Wildcard: Subdomains at one level, such as *.company.com.

In this example, the wildcard covers shop.company.com and mail.company.com. It does not cover a.shop.company.com, which is one level deeper. The base domain company.com must also be explicitly included in the certificate.

Covering a name such as mail.company.com in a TLS certificate does not sign or encrypt email messages; that requires S/MIME.

How do Basic, Secure Site and Secure Site Pro differ?

These are different product packages. Choose the package that fits your needs, then the domain names and coverage. Included services and add-ons vary by product and offer, so check the details of your specific package.

What is the difference between a public and a private certificate?

Public: Issued from a trust chain recognized by supported browsers and systems, subject to public issuance requirements.
Private or internal: Used within an organization; trust in the issuing authority must be configured on the relevant computers and systems.

“Internal” does not simply mean that a website requires a login. The difference is who trusts the certificate and how that trust is configured.

What is a CSR, and who creates it?

A Certificate Signing Request (CSR) contains a public key and the required certificate details. Your IT team, server administrator or hosting provider creates it in the environment where the certificate will be used. The private key stays with you and is not sent with the CSR.

What should I know about renewal and installation?

The subscription period and the validity of an individual certificate may differ. Make sure certificates are renewed and installed before they expire. Alerts support tracking; automation requires the appropriate configuration and integrations.

What is a VMC, and does it secure email?

A Verified Mark Certificate (VMC) verifies a logo for BIMI display in supporting email services, subject to their requirements. It does not replace S/MIME certificates for signing or encrypting email.

Before ordering, prepare the use case, domain names, organization details and an installation contact.
