The Two Certificates in One

UCC Wildcard SSL (OV) exists because two separate needs, Exchange host name support and subdomain coverage, often show up on the same server at once. A standard UCC certificate covers named domains like mail.example.com individually. A standard wildcard covers unlimited subdomains under a single domain. This certificate does both at once, letting a business list several base domains and have every subdomain under each of them covered automatically.

Business verification runs at the same OV depth as every other Comodo OV product: Sectigo confirms the requesting organization is a legitimate, registered entity and verifies its physical address before issuing the certificate. That verified identity then appears in the certificate's detail view.

⚠️
Site seal behaviour varies by reseller: Whether the verified organization name appears in a visible site seal depends heavily on the specific reseller SKU. Some listings advertise organization name display, others describe a static seal showing only the Comodo brand mark. Confirm this detail before assuming the seal will show a company name.

How Business Verification Works

The validation sequence combines domain control checks across every base domain with the same organization vetting every OV certificate in the Comodo line requires. Total issuance typically runs 1 to 3 business days from document submission — the same window as the standard UCC (OV) product, since the wildcard component adds domain structure rather than an additional verification step.

Minutes to hours per domain

Domain Control Validation

DNS record or email confirmation for each base domain. HTTP file validation is not accepted for wildcard entries, so teams relying on file-upload automation need a DNS-based workflow before placing the order.

2
Same day to 2 business days

Business Registration Check

Sectigo verifies company registration and physical address against public records, confirming the organization is a real, legally registered entity. This is the step that separates OV from DV issuance on this product.

3
Adds 1 to 2 business days if required

Telephone or Alternate Verification

A callback to a verified business number, or an accepted substitute such as a Dun & Bradstreet listing or Legal Opinion Letter. This step is mandatory for OV and can stall issuance if the business lacks a qualifying listing.

💡
DNS validation is required for wildcard entries. Plan for a DNS-based workflow before placing the order. Teams with issuance automation built around HTTP file uploads need to rebuild that process for this certificate.

Domain and Subdomain Math

Most reseller listings bundle 2 wildcard SAN domains by default, with additional wildcard or standard SAN entries purchasable beyond that. Each wildcard entry covers every present and future subdomain under that base domain without a separate purchase or revalidation.

How coverage actually scales

Subdomains under a listed base domain (added before or after issuance)Covered automatically
A new unrelated domain not yet on the certificateNeeds a new SAN entry
Second-level subdomains like staging.api.example.comOutside wildcard scope
The bare root domain (example.com)Only if listed as a SAN
📋
Domain ceiling varies sharply by reseller. Most listings cap around 250 total domains while at least one lists coverage up to 2,000. That gap is large enough to confirm directly with the reseller before purchasing, since it affects how the certificate scales for a large multi-brand deployment.

What It Actually Costs

Pricing on this certificate spans a wider range than almost any other product in the Comodo UCC family, from $60.40 on a multi-year term to $349 first-year. The underlying Sectigo certificate and validation process are identical across resellers. Differences reflect term length, included domain count, and per-SAN add-on structure.

Site seal behaviour is not consistent across these listings. Some pages describe the seal as static, showing only the Comodo brand mark, while others advertise organization name display. Confirm which version the specific SKU includes before assuming the seal will show business identity to visitors.

Key Changes for 2026

The same CA/Browser Forum rules affecting every publicly trusted certificate this year apply here, and the wildcard structure makes the practical impact larger than it is on a flat UCC certificate.

1

Shorter Validity, Larger Reissuance Events

Maximum validity per issuance dropped to 200 days as of March 2026, so this certificate needs reissuing roughly twice a year. Because a single reissue event revalidates every base domain and its wildcard entry at once, a certificate carrying several base domains now represents a larger single point of renewal work than it did under the older annual cycle. Automation matters more here than on a flat UCC certificate.

2

Domain Validation Reuse Shortened, DNS Automation More Important

The window for reusing a prior domain validation result has been shortened, and combined with the restriction against HTTP validation for wildcard entries, this pushes most deployments of any real size toward DNS-based automation rather than manual, once-a-year renewal. Teams still using manual file upload workflows need to plan a migration before the next renewal cycle.

Where It Wins and Loses

Where It Wins

  • Covers unlimited subdomains under every listed base domain without individual SAN purchases per subdomain
  • Business verification confirms the requesting organization's legal identity before issuance
  • Purpose-built for Exchange Autodiscover and Office Communications Server host name patterns
  • Unlimited server licensing supports shared hosting environments running many client sites
  • Up to $250,000 warranty on most reseller listings

Where It Loses

  • HTTP file validation is not accepted for wildcard entries, requiring DNS-based validation only
  • Requires SNI support on the serving infrastructure, ruling out some legacy load balancers
  • Site seal behaviour is inconsistent across resellers, with some showing only a brand mark
  • Meaningfully more expensive than the standard UCC (OV) when subdomain coverage is not needed
  • Domain ceiling claims vary sharply between resellers for the same underlying product

UCC Wildcard vs. Standard UCC (OV)

Both certificates run the same business verification process and chain to the same root. The difference comes down entirely to whether subdomains need coverage under the listed domains. Paying the wildcard premium for an Exchange environment that never adds subdomains adds ongoing cost without adding protection.

💡
When the wildcard premium is worth paying: Environments that regularly spin up new subdomains, such as growing multi-tenant Exchange deployments, avoid a steady stream of SAN purchases and revalidation by choosing the wildcard version upfront. For a fixed domain list that never changes, the standard UCC (OV) delivers the same business verification at lower cost.

Ideal Use Cases

Good fit

Growing Exchange Environments

Organizations that regularly add new mail or collaboration subdomains benefit from coverage that scales without a new SAN purchase each time.

Good fit

Multi-Brand Enterprises with Subdomain Structures

Businesses running several base domains, each with departmental or regional subdomains, consolidate all of it under one certificate and one renewal date.

Good fit

Managed Service Providers Hosting Client Exchange Servers

Providers managing subdomains across multiple client domains reduce certificate administration significantly compared to per-subdomain SAN certificates.

Consider alternatives

Fixed, Flat Exchange Deployments

Environments with a stable, known domain list that never adds subdomains get the same business verification more cheaply from the standard UCC (OV) certificate.

Consider alternatives

Legacy Infrastructure Without SNI Support

Older load balancers or appliances lacking SNI support cannot serve this certificate correctly across shared hosting.

Consider alternatives

Teams Relying on HTTP-Based Automation

Wildcard entries require DNS or email validation. Teams with issuance workflows built around HTTP file validation need to rebuild that automation before adopting this certificate.

Frequently Asked Questions

No. Each base domain added to the certificate gets unlimited subdomain coverage under itself, but an unrelated additional domain still needs its own SAN entry to gain the same subdomain coverage. The wildcard scope applies per listed base domain, not across the entire certificate.
No. Wildcard SAN entries require DNS record or email-based domain control validation. HTTP file validation is not accepted for wildcard domains on this certificate. Teams with file-upload automation need to migrate to a DNS-based workflow before placing the order.
Most reseller listings bundle 2 wildcard SAN domains by default, with additional SAN entries, wildcard or standard, purchasable beyond that base allowance. Confirm the specific inclusion with the reseller, since the base package varies between sellers.
It depends on the reseller. Some listings advertise organization name display as part of the package, others describe a static seal showing only the Comodo brand mark. Confirm this on the specific product page before purchase, since it varies even between listings of the same certificate.
Both run identical business verification and share the same encryption and key length. This certificate adds unlimited subdomain coverage per base domain and costs more. The standard version covers flat named domains only, accepts HTTP validation, and costs significantly less when subdomain coverage is not needed.
A maximum of 200 days per issuance under the current CA/Browser Forum cap. Multi-year subscriptions still bill across multiple years but require periodic reissuance within that term. Because wildcard SANs require DNS-based validation, reissuance automation is worth setting up before the first renewal cycle rather than after.
