Multi-brand consumer groups
Separate product brands (brandA.in, brandB.in) each with subdomain fleets — consolidated under one wildcard certificate and one ops renewal.
In short: Multi-domain wildcard SSL combines multiple wildcard patterns —
e.g. *.productA.in and *.productB.in — plus optional explicit SAN hostnames on
one TLS certificate with one renewal date.
PrecisionTech supplies multi-domain wildcard SSL from GlobalSign, Sectigo, and DigiCert with INR billing,
DNS architecture review, and deployment support in Kochi and across India.

Multi-Domain Wildcard Tiers — DV or OV?
Validation tier applies to the entire certificate. EV wildcard is not permitted under CA rules. Pricing depends on wildcard SAN count — contact for a scoped INR quote.
DV Multi-Domain Wildcard
Domain control only · fastest issuance
From Contact for INR quote
- ✓ Staging & internal multi-brand
- ✓ Multiple *.domain patterns
- — No org name in cert
Enterprise multi-brand
OV Multi-Domain Wildcard
Organisation + all domains verified
From Contact for INR quote
- ✓ 1–3 day typical validation
- ✓ Production multi-brand estates
- ✓ Verified company name in cert
Single Wildcard SSL
One *.domain.com only
From Contact for INR quote
- ✓ Single domain subdomain fleet
- ✓ Simpler when one brand only
- ✓ Often lower cost for one domain
Note: EV wildcard certificates are not permitted at any scope. Use EV SSL on primary domains plus OV multi-domain wildcard for other hostname patterns.
What is Multi-Domain Wildcard SSL?
Standard Wildcard SSL covers subdomains of a single registered domain. Multi-domain wildcard SSL extends that model: one certificate can include wildcard entries for more than one base domain — for example *.productA.in and *.productB.in — plus explicit SAN names such as apex domains or mail hosts that wildcards alone do not cover.
This product class suits Indian enterprises with multiple consumer brands, acquired domains, or regional TLD variants (.in, .co.in, .com) that share one operations team and one certificate renewal calendar. Validation tier (DV or OV) applies to the entire certificate — EV wildcard is not permitted under CA/Browser Forum rules.
PrecisionTech architects mixed SAN lists before ordering — avoiding gaps where apex domains, autodiscover hosts, or nested subdomains fall outside wildcard coverage. We supply through GlobalSign, Sectigo, and DigiCert partnerships and compare against separate SAN SSL or single wildcards when total cost differs.

Glossary
- Multi-domain wildcard SSL
- One certificate with multiple *.domain.com wildcard entries — often plus explicit SAN hostnames.
- Wildcard SAN entry
- A Subject Alternative Name field containing a wildcard pattern like *.brand.in rather than a fixed FQDN.
- Mixed SAN list
- Certificate combining wildcard patterns and explicit hostname entries on one credential.
- Base domain
- Registered domain root (example.in) that anchors each wildcard pattern (*.example.in).
- Apex SAN entry
- Explicit bare domain (example.in) added alongside *.example.in because wildcard does not cover apex.
- Single-level wildcard rule
- *.shop.example.in covers tenant.shop.example.in but not deeper nested names without additional planning.
- EV wildcard prohibition
- CA/Browser Forum rules prohibit publicly trusted EV wildcard at any scope.
- Regional TLD variants
- Multiple TLDs for one brand (.in, .co.in, .com) — common multi-domain wildcard use case.
- SAN reissue
- Mid-term certificate replacement to add wildcard domains or explicit hostnames.
- Certificate consolidation
- Replacing multiple single wildcards with one multi-domain wildcard to reduce renewal overhead.
- Hostname architecture review
- PrecisionTech DNS tree analysis before CSR to catch apex and nested subdomain gaps.
- UCC wildcard context
- Enterprise products extending unified communications / multi-domain models to include wildcard patterns.

Frequently Asked Questions
1. What is multi-domain wildcard SSL?
Multi-domain wildcard SSL places more than one wildcard pattern — such as *.brandA.in and *.brandB.in — on a single certificate, often alongside explicit hostname entries for apex or mail servers.
2. How is it different from a single Wildcard SSL certificate?
A standard Wildcard SSL covers one domain's subdomains. Multi-domain wildcard extends wildcard coverage across multiple registered base domains on one cert — one renewal, one deployment artifact.
3. Can I get EV multi-domain wildcard SSL?
No. CA/Browser Forum rules prohibit publicly trusted EV wildcard certificates at any scope. Use OV multi-domain wildcard or combine EV SSL on primary domains with wildcard/OV SAN for other hostnames.
4. Does a wildcard cover the apex domain?
Wildcard patterns cover subdomains, not necessarily the bare apex. PrecisionTech adds explicit SAN entries for example.in when you need both apex and *.example.in on the same certificate.
5. When should I choose multi-domain wildcard vs SAN SSL?
Choose multi-domain wildcard when you have predictable subdomain fleets across several domains. Choose SAN SSL when hostnames are a fixed, finite list without open-ended subdomain creation.
6. How much does multi-domain wildcard SSL cost in India?
Pricing depends on the CA, validation tier (DV or OV), number of wildcard SAN entries, and explicit hostname count. PrecisionTech quotes in INR with GST invoice. Contact us for a scoped proposal.
7. Can I add another wildcard domain mid-term?
Most CAs support reissue with an expanded SAN list during the certificate term, subject to revalidation. PrecisionTech manages reissue requests and redeployment.
8. Which CAs offer multi-domain wildcard through PrecisionTech?
Product availability varies. We quote GlobalSign, Sectigo, and DigiCert options via our GlobalSign, Sectigo, and DigiCert partnerships based on your SAN list and validation tier.
9. Does PrecisionTech validate nested subdomain coverage?
Yes. Wildcard covers one level only — *.shop.example.in does not secure tenant.shop.example.in. We map your DNS tree and flag gaps before you order.
10. Should I choose DV or OV multi-domain wildcard SSL?
11. Can I mix wildcard and non-wildcard SAN entries on one certificate?
Yes. Most multi-domain wildcard products allow a mixed SAN list — e.g.
*.brandA.in, *.brandB.com, plus explicit entries for apex domains, autodiscover, or mail hosts.12. Is multi-domain wildcard suitable for acquired brands?
Yes. Indian enterprises with acquired consumer brands often consolidate
*.legacybrand.in and *.newbrand.in on one certificate under unified ops and one renewal calendar.13. What encryption standards does multi-domain wildcard SSL use?
Modern products use SHA-256 signatures with 2048-bit RSA keys (or ECDSA where supported), compatible with TLS 1.2 and TLS 1.3. Browser trust matches standard wildcard SSL from the same CA.
14. Does PrecisionTech help generate a multi-domain wildcard CSR?
Yes. We guide CSR creation with correct wildcard common name format, complete mixed SAN list, and private key protection expected by GlobalSign, Sectigo, or DigiCert.
15. What happens when my multi-domain wildcard certificate expires?
Expired certificates trigger browser warnings across all covered wildcard patterns and explicit SAN names. PrecisionTech tracks expiry and initiates renewal with fresh validation before production certificates lapse.
16. Is multi-domain wildcard cheaper than separate wildcards per domain?
Often yes when you operate three or more wildcard domains — one renewal and one deployment artifact reduce ops overhead. PrecisionTech compares total cost vs separate single wildcards during discovery.
17. Does multi-domain wildcard work on cloud load balancers?
Yes. We deploy on AWS ALB/NLB, Azure Application Gateway, F5, HAProxy, and CDN origin servers — ensuring SNI presents the correct certificate for each hostname pattern.
18. How long does multi-domain wildcard validation take in India?
DV multi-domain wildcard typically completes in minutes to hours per domain. OV takes 1–3 business days plus organisation vetting. PrecisionTech pre-reviews documents to reduce delays.
19. How does PrecisionTech invoice multi-domain wildcard purchases?
PrecisionTech bills in Indian Rupees with GST invoice for B2B buyers in India. We procure the underlying CA certificate on your behalf with deployment support as part of the engagement.
20. Why buy through PrecisionTech instead of directly from a CA?
PrecisionTech adds INR billing with GST, DNS architecture review, multi-CA comparison, mixed SAN list planning, reissue coordination, chain installation assistance, and renewal tracking — reducing coverage gaps common on complex orders.
21. Does multi-domain wildcard cover .in and .com variants of the same brand?
Yes, when both base domains are listed as separate wildcard SAN entries (e.g.
*.brand.in and *.brand.com). Each base domain requires its own wildcard pattern on the certificate.22. How do I start a multi-domain wildcard SSL order with PrecisionTech?
Share your domain list, subdomain architecture, and validation tier via precisiontech.in/contact/. We return a scoped CA recommendation, SAN/wildcard slot plan, and INR quote, then coordinate validation, issuance, and installation through renewal.
