Why choose a Sectigo SSL certificate?

Sectigo is one of the world’s leading Certificate Authorities and provides SSL/TLS certificates for websites and organisations of all sizes.

From a simple website requiring fast Domain Validation to companies that need verified organisational identity or protection for complex multi-domain infrastructures, the Sectigo SSL portfolio offers a wide range of options.

All Sectigo SSL certificates provide strong encryption and trusted HTTPS protection, helping secure information exchanged between your website and its visitors, including login credentials, personal information, contact forms and other sensitive data.

Choosing the right certificate mainly depends on two factors: the level of identity validation you require and the number of domains or subdomains you need to protect.

What about Comodo SSL certificates?

If you have been buying SSL certificates for some time, you are probably familiar with the Comodo SSL name.

Comodo CA became Sectigo in 2018, following its separation from the Comodo Group. Sectigo is therefore the Certificate Authority behind the SSL/TLS certificate portfolio historically associated with Comodo CA.

While Sectigo is now the main Certificate Authority brand, the Comodo name remains widely recognised in the SSL market, and several certificate products and product families continue to be available under familiar Comodo-related branding.

So, if you are looking for a Comodo SSL certificate, you are in the right place: today these certificates are part of the broader Sectigo SSL/TLS ecosystem, using Sectigo’s trusted certificate infrastructure.

You can browse the Sectigo certificates on this page or explore our complete range of Comodo SSL certificates to find the product that best matches your requirements.

Sectigo DV, OV and EV SSL certificates

Sectigo offers the three main SSL/TLS validation levels: Domain Validation (DV), Organisation Validation (OV) and Extended Validation (EV).

Sectigo Domain Validation (DV) SSL

DV SSL certificates provide the fastest and simplest form of SSL/TLS validation.

The Certificate Authority verifies that the applicant controls the domain, without performing checks on the organisation behind the website.

Sectigo DV certificates are an excellent choice for:

• Blogs and personal websites
• Small business websites
• Landing pages
• Development and testing environments
• Websites that primarily require HTTPS encryption

Because the validation process is automated, DV certificates can normally be issued very quickly once domain control has been successfully verified.

Sectigo Organization Validation (OV) SSL

OV SSL certificates add verified organisational identity to standard domain validation.

Before issuing the certificate, Sectigo verifies information about the organisation requesting it. This makes OV certificates particularly suitable for companies and organisations that want their SSL certificate to contain verified business information.

Sectigo OV SSL certificates are a good choice for:

• Corporate websites
• Customer and partner portals
• Professional services
• Business applications
• Websites collecting customer information

If your website represents a registered business or organisation, an OV certificate can provide an additional level of identity assurance compared with a standard DV certificate.

Sectigo Extended Validation (EV) SSL

EV SSL certificates require a more extensive validation process and provide the highest level of organisational identity verification available for publicly trusted SSL/TLS certificates.

Sectigo EV certificates are designed for organisations where verified identity is particularly important, including:

• E-commerce websites
• Financial and payment services
• Large corporate websites
• Online platforms handling sensitive information
• High-profile brands and organisations

Modern browsers no longer display the organisation name prominently in the address bar as older browsers once did, but EV certificates still provide the highest level of identity verification within the certificate itself.

Sectigo Wildcard SSL certificates

Need to protect multiple subdomains?

A Sectigo Wildcard SSL certificate allows you to secure a domain and an unlimited number of first-level subdomains using a single certificate.

For example, a Wildcard certificate for:

*.example.com

can protect addresses such as:

www.example.com
mail.example.com
shop.example.com
portal.example.com
support.example.com

This makes Wildcard SSL particularly convenient for organisations running several services or applications under the same domain.

Instead of purchasing and managing a separate SSL certificate for every subdomain, you can simplify certificate management with a single Wildcard certificate.

Sectigo offers Wildcard certificates with different validation levels, allowing you to choose between fast Domain Validation and certificates providing verified organisational identity.

---

Sectigo Multi-Domain SSL certificates

If you need to secure several different domain names, a Sectigo Multi-Domain SSL certificate, also known as a SAN certificate, can protect multiple hostnames within a single certificate.

For example, one Multi-Domain certificate could protect:

example.com
example.net
mycompany.eu
shop.example.org

This can considerably simplify SSL management for businesses operating multiple websites, brands, applications or online services.

Multi-Domain certificates are also useful for organisations that want to consolidate several SSL certificates into a smaller and more manageable certificate infrastructure.

Depending on the product, additional domains can be added as Subject Alternative Names (SANs).

---

Wildcard or Multi-Domain SSL: which should you choose?

The difference is straightforward.

Choose a Wildcard SSL certificate when you need to protect many subdomains belonging to the same domain.

Choose a Multi-Domain SSL certificate when you need to protect different domain names with a single certificate.

For more complex infrastructures, Sectigo also offers solutions capable of combining multiple domains and Wildcard names, providing flexible protection for larger environments.

---

Which Sectigo SSL certificate is right for you?

The best certificate depends on your website and infrastructure.

If you simply need HTTPS for a single website, a Sectigo DV SSL certificate is often the simplest solution.

If the website represents a company and you want verified organisational information included in the certificate, consider a Sectigo OV SSL certificate.

For organisations requiring the highest level of identity validation, Sectigo EV SSL certificates provide enhanced organisational verification.

If you operate numerous subdomains, choose a Wildcard SSL certificate. If you manage several different domains, a Multi-Domain (SAN) SSL certificate can make certificate management much easier.

You can compare the available Sectigo SSL certificates above to find the combination of validation level, domain coverage and features that best fits your requirements.

Frequently Asked Questions about Sectigo SSL Certificates

Is Sectigo a trusted Certificate Authority?

Yes. Sectigo is a globally recognised Certificate Authority. Its public SSL/TLS certificates use certificate chains trusted by major modern browsers, operating systems and mobile devices.

What is the difference between Sectigo and Comodo SSL?

Sectigo was formerly known as Comodo CA. The Certificate Authority business was renamed Sectigo in 2018. You may therefore still encounter older documentation, product names or references using the Comodo SSL name.

Are Sectigo SSL certificates compatible with all browsers?

Sectigo SSL certificates are designed for broad compatibility with major modern browsers, operating systems and mobile devices.

As with any publicly trusted certificate, correct installation of the certificate and intermediate certificate chain is important for maximum compatibility.

How quickly can a Sectigo SSL certificate be issued?

Issuance time depends primarily on the validation level.

DV certificates can generally be issued very quickly after successful domain validation because the process is largely automated.

OV and EV certificates require verification of the organisation and therefore normally take longer to issue.

Do I need a DV, OV or EV certificate?

Choose DV if your primary requirement is HTTPS encryption and proof of domain control.

Choose OV if you also want the Certificate Authority to verify your organisation.

Choose EV when you require the highest level of organisational identity verification available with a public SSL/TLS certificate.

All three certificate types provide strong TLS encryption. The main difference is the level of identity verification performed before issuance.

Can one Sectigo SSL certificate protect multiple websites?

Yes. A Sectigo Multi-Domain (SAN) certificate can protect multiple domain names with a single certificate.

If you instead need to protect multiple subdomains of the same domain, a Sectigo Wildcard certificate is generally the more appropriate solution.

Can a Sectigo Wildcard certificate protect unlimited subdomains?

A Wildcard certificate can secure an unlimited number of subdomains at the level covered by the wildcard.

For example, *.example.com can protect shop.example.com, mail.example.com and portal.example.com.

However, it does not automatically cover deeper levels such as server.mail.example.com.

What happens when my Sectigo SSL certificate expires?

An expired SSL certificate is no longer considered valid by browsers and visitors may see a security warning.

For this reason, the certificate must be renewed or replaced before expiration. As SSL/TLS certificate validity periods become progressively shorter, automated certificate management is becoming increasingly important.

EuroSSL also offers SSL certificates and solutions supporting automated issuance and renewal for organisations that want to reduce manual certificate management.
