Comodo SSL certificates

PositiveSSL is the everyday domain-validated certificate for one public hostname. It turns http into HTTPS with a trusted padlock, a site seal, and 256-bit encryption, without a lengthy organisation review.

• ✓Instant domain validation
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

EssentialSSL is a domain-validated certificate for teams that want a named Comodo/Sectigo DV product with a site seal and fast issuance. It encrypts a single public hostname and is a step up in positioning from entry-level PositiveSSL, without organisation paperwork.

PositiveSSL ACME Certificate-as-a-Service is Sectigo/PositiveSSL domain-validated TLS delivered through ACME, the same protocol used by Certbot, win-acme, Traefik, Kubernetes cert-manager, and many cPanel/Plesk plugins. You point an ACME agent at the CaaS credentials; the agent issues, installs, and renews. That is the low-friction answer when certificate lifetimes shrink to 47 days and you already run ACME, not a one-line DigiCert Automate installer.

• ✓Instant domain validation
• ✓256-bit encryption

Comodo Domain Validated UCC is a SAN certificate issued after domain control on every name, typically minutes, no organisation on the certificate. Use it for public mail/web hostname lists when OV is not required. PositiveSSL Multi-Domain is often the lower List Price DV SAN; specify DV UCC when the bill of materials uses that product name.

• ✓Covers multiple domains with one certificate
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

PositiveSSL Multi-Domain Wildcard is for teams that run several brands or properties and want wildcard coverage on more than one registered domain from a single DV certificate, for example *.shop.in and *.brand.com together.

• ✓Multi-domain + wildcard subdomains in one cert
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

Comodo SSL Wildcard Certificate (DV) covers *.example.com after domain control, typically minutes, with no organisation on the certificate. Use it when the purchase order says Comodo Wildcard rather than PositiveSSL Wildcard or Sectigo SSL Wildcard. Nested hosts and extra registered domains need other SKUs.

• ✓Instant domain validation
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility

Personal Authentication Enterprise is the PAC S/MIME SKU aimed at rolling certificates to employees: sign mail, encrypt when both parties have certs, and (where the client supports it) use the same identity for client TLS to internal apps. It is still not a website certificate and not a CCA DSC.

• ✓Digitally signs outgoing emails
• ✓End-to-end email encryption
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility

InstantSSL is organisation-validated (OV). The certificate authority checks your company registration as well as domain control, so visitors and procurement teams see a certificate tied to a real business, not only a hostname.

• ✓Business identity verified by CA
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

InstantSSL Pro is the higher InstantSSL OV: same organisation check as InstantSSL, typically a stronger warranty band on this SKU. Use it when you need a verified business on the certificate and procurement wants the Pro line rather than the base InstantSSL.

• ✓Business identity verified by CA
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

InstantSSL Premium (OV) is organisation-validated TLS for one hostname in the InstantSSL family. Encryption matches other public certificates; the CA still checks the registered business. Use this SKU when the brief says Premium rather than InstantSSL, InstantSSL Pro, or Elite.

• ✓Business identity verified by CA
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

Comodo Multi-Domain SSL (OV) is a SAN/UCC pack: several hostnames on one organisation-validated certificate in the Comodo product line. Use it when the purchase order still says Comodo MDC rather than Sectigo OV Multi-Domain. Cache “minutes / domain” tags are misleading, OV still takes business days after documents. “Up to 250” is a max, not included.

• ✓Covers multiple domains with one certificate
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

Comodo Unified Communications Certificate is a SAN pack aimed at the historic Exchange/OCS pattern: several public hostnames (for example autodiscover, mail, owa, www) on one file so you are not binding a certificate per IP. It is still a public-trust TLS certificate, every name must be a CA-acceptable FQDN. Confirm included SAN versus extras, and whether this SKU is DV or OV on the live product, before you order.

• ✓Covers multiple domains with one certificate
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

Elite SSL (OV) is organisation-validated TLS for one hostname in the Comodo product line. It sits above InstantSSL / InstantSSL Premium on warranty positioning while remaining OV, not EV. Visitors get HTTPS and a CA seal; Chrome does not show a green bar. Use it when the purchase order says Elite SSL rather than InstantSSL or Sectigo OV.

• ✓Business identity verified by CA
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

InstantSSL Premium Wildcard (OV) is organisation-validated coverage for first-level subdomains of one base in the InstantSSL Premium line. Cache “minutes / domain” tags are wrong for OV. Nested names are not covered. There is no EV wildcard.

• ✓Instant domain validation
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility

Enterprise SSL is the entry SKU of the Comodo Enterprise OV line: organisation-validated TLS, a CA site seal, and a higher warranty band than InstantSSL. Foreign storefronts sometimes bundle a short cWatch trial with this certificate, Crozsi will only include cWatch if the live product entitlement says so; otherwise quote cWatch as its own catalog item.

• ✓Business identity verified by CA
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

Comodo Multi-Domain Wildcard (OV) combines SAN and first-level wildcard coverage under organisation validation. Use it when several registered domains each need *.domain coverage on one certificate. Nested hosts still need extra names. Confirm included SAN versus extras on the live quote.

• ✓Multi-domain + wildcard subdomains in one cert
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

Comodo OV Unified Communications Wildcard is the UCC-labelled SAN+wildcard certificate: several public names and first-level wildcard bases on one organisation-validated file. Historic Exchange examples (mail, autodiscover, smtp) still work when those names are public DNS. Do not expect .local or private IPs on public trust.

• ✓Multi-domain + wildcard subdomains in one cert
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

Enterprise SSL Pro is the richer Comodo Enterprise OV SKU: same organisation validation as Enterprise SSL, with Pro positioning (warranty band and any extra entitlements on the live product). Marketing pages sometimes list a year of cWatch or a dedicated specialist. We only promise what the live catalog and fulfilment include. The certificate itself is still OV TLS, not a managed-security contract.

• ✓Business identity verified by CA
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

Enterprise SSL Pro Wildcard is the highest Comodo wildcard SKU: organisation-validated coverage for unlimited first-level subdomains of one base. Extra marketing bundles are only included if the live entitlement says so. Nested names are not covered. There is no EV wildcard. Enterprise Pro EV is FQDN/SAN, not *.

• ✓Secures unlimited subdomains (*.domain.com)
• ✓Instant domain validation
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility

PositiveSSL EV is extended validation: the CA checks the legal entity thoroughly before issue. Visitors still see HTTPS and a padlock. Chrome no longer paints a green address bar, but the organisation name remains on the certificate for anyone who inspects it, the right EV product when procurement wants that bar of trust without a DigiCert list price.

• ✓Highest level of identity verification
• ✓Organisation name visible in browser
• ✓Business identity verified by CA
• ✓256-bit encryption

Comodo EV SSL is extended-validation TLS under the Comodo product name. The CA performs the strictest public-trust identity review.

• ✓Highest level of identity verification
• ✓Organisation name visible in browser
• ✓Business identity verified by CA
• ✓256-bit encryption

PositiveSSL EV Multi-Domain combines PositiveSSL EV identity checks with SAN coverage for several FQDNs.

There is no EV wildcard and no green bar in current Chrome.

• ✓Covers multiple domains with one certificate
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
• ✓Comodo trusted root

Comodo EV Multi-Domain SSL covers several FQDNs on one extended-validation certificate. Confirm included SAN versus extras on the live quote. There is no EV wildcard. Current browsers do not restore a green address bar.

Current Chrome does not show a green address bar.

• ✓Highest level of identity verification

Comodo Code Signing is a software-signing certificate, not a website TLS certificate. It digitally signs executables, installers, and scripts so Windows and other OS trust dialogs show a verified publisher instead of Unknown Publisher. Organisation validation applies to the publisher, not to a web domain.

• ✓Removes 'Unknown Publisher' warning
• ✓Signs EXE, DLL, MSI, scripts & drivers
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility

Comodo EV Code Signing is an extended-validation software-signing certificate, not HTTPS for a website. The CA checks the publisher at EV depth. Publicly trusted code-signing keys are issued onto hardware (USB token or HSM). You do not get a downloadable private key file. Use Authenticode (signtool) with a timestamp so signatures stay valid after the certificate expires.

• ✓Removes 'Unknown Publisher' warning
• ✓Signs EXE, DLL, MSI, scripts & drivers
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility

Personal Authentication Basic is an S/MIME / email-signing certificate. It lets a person digitally sign outgoing mail and encrypt messages to recipients who share certificates. It is not a website TLS certificate and will not put HTTPS on a domain.

• ✓Digitally signs outgoing emails
• ✓End-to-end email encryption
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility

Personal Authentication Pro is a higher PAC S/MIME certificate than Basic: the same job (sign outbound mail; encrypt when the recipient also has a certificate) with Pro positioning. It is not HTTPS, not code signing, and not an Indian CCA-licensed DSC for MCA/GST filings.

• ✓Digitally signs outgoing emails
• ✓End-to-end email encryption
• ✓256-bit encryption
• ✓99.9% browser & mobile compatibility
