Multi-tenant SaaS
Customer subdomains (tenant.app.in) on one parent domain — one wildcard covers the entire fleet without per-tenant certificate purchases.
In short: A Wildcard SSL certificate encrypts HTTPS for every
first-level subdomain under your domain using one *.yourdomain.com entry —
one validation cycle, one renewal, unlimited server installs on most products.
PrecisionTech supplies wildcard SSL from GlobalSign and Sectigo in DV or OV tiers with INR billing,
DNS architecture review, and deployment support in Bengaluru and across India.

Wildcard SSL Tiers — DV or OV Validation?
Wildcard SSL is available at Domain Validation and Organisation Validation tiers — not EV. Choose based on whether certificate details must show verified business identity. Pricing is quote-based in INR.
DV Wildcard
Domain control only · fastest issuance
From Contact for INR quote
- ✓ Minutes to hours validation
- ✓ Staging & internal subdomains
- — No org name in cert
Customer-facing SaaS
OV Wildcard
Organisation + domain verified
From Contact for INR quote
- ✓ 1–3 day typical validation
- ✓ Production SaaS subdomains
- ✓ Verified company name in cert
Multi-Domain SAN
Explicit hostname list · flexible nesting
From Contact for INR quote
- ✓ Named hostnames on one cert
- ✓ When wildcard one-level rule fails
- ✓ Mixed apex + subdomain coverage
Note: Extended Validation (EV) wildcard certificates are not permitted under CA/Browser Forum rules. Use EV SSL on primary domains plus OV wildcard or SAN for subdomains.
What is a Wildcard SSL Certificate?
A Wildcard SSL certificate uses the *.yourdomain.com pattern to secure every first-level subdomain on that domain — app, api, staging, docs — without purchasing separate certificates for each hostname. One validation cycle, one renewal date, and unlimited server licensing on standard products make wildcard SSL the cost-effective choice for Indian SaaS vendors, ERP portals with tenant subdomains, and teams running dev/staging/production tiers on one registered domain.
Wildcard certificates are available at Domain Validation and Organisation Validation tiers. Extended Validation (EV) wildcard is not permitted under CA/Browser Forum baseline requirements. Important limitation: wildcard covers one level only — *.shop.example.in secures tenant.shop.example.in but not deeper nested names like a.b.shop.example.in without additional SAN planning.
PrecisionTech procures wildcard SSL from global CAs — GlobalSign Wildcard SSL and Sectigo Wildcard SSL — with INR billing, GST invoice, DNS architecture review before CSR, and installation assistance on Apache, Nginx, IIS, cloud load balancers, cPanel, and Plesk.

Who Uses Wildcard SSL in India?
Dev / staging / production tiers
staging.example.in, api.example.in, app.example.in — shared validation and renewal across environment hostnames.
ERP & business portals
Module subdomains (crm, hr, finance) under one corporate domain with consistent HTTPS encryption.
API gateways & microservices
api, auth, billing subdomains behind load balancers — deploy same wildcard cert across multiple origin servers.
Agency & white-label hosting
Client subdomains under agency domain where wildcard reduces certificate management overhead.
E-learning & LMS platforms
Course and tenant subdomains (school.platform.in) requiring encrypted access at scale.

Glossary
- Wildcard SSL
- A TLS certificate using *.yourdomain.com to secure unlimited first-level subdomains under one validation cycle.
- First-level subdomain
- A hostname one dot below the registered domain — e.g. app.example.in is first-level under example.in.
- Apex domain
- The bare registered domain (example.in) without subdomain prefix — not always included in wildcard coverage unless explicitly added.
- DV Wildcard
- Domain-validated wildcard — issued after domain control proof only; fastest wildcard tier.
- OV Wildcard
- Organisation-validated wildcard — includes verified business name in certificate after CA org vetting.
- Single-level wildcard rule
- *.shop.example.in covers tenant.shop.example.in but not deeper nested names like a.b.shop.example.in without SAN planning.
- EV wildcard prohibition
- CA/Browser Forum rules prohibit publicly trusted Extended Validation wildcard certificates.
- Wildcard CSR
- Certificate Signing Request with common name *.yourdomain.com — format must match CA expectations exactly.
- Unlimited server licensing
- Standard wildcard products allow installing the same certificate on multiple servers within your environment.
- SAN certificate alternative
- Multi-domain certificate listing explicit hostnames — alternative when wildcard one-level rule is insufficient.
- Multi-tenant SaaS pattern
- Architecture where each customer gets tenant.yourapp.in — ideal wildcard use case when all tenants share one parent domain.
- Star certificate
- Informal industry term for wildcard SSL — the asterisk (*) in *.domain.com.

Frequently Asked Questions
1. What is a Wildcard SSL certificate?
A Wildcard SSL certificate secures unlimited first-level subdomains of a domain using a single *.yourdomain.com entry. One certificate covers app.yourdomain.com, api.yourdomain.com, and other sibling subdomains without buying separate certs for each hostname.
2. Does Wildcard SSL cover the apex domain (yourdomain.com)?
A wildcard for *.example.in covers first-level subdomains but not necessarily the bare apex example.in. PrecisionTech ensures your CSR and SAN list include every hostname you need before CA submission.
3. Can I get an EV Wildcard SSL certificate?
No. CA/Browser Forum rules prohibit publicly trusted Extended Validation wildcard certificates. For maximum assurance on a primary domain, use EV SSL on the apex and OV wildcard or SAN certificates for subdomains.
4. Should I choose DV or OV Wildcard SSL?
DV wildcard issues fastest — ideal for internal or staging subdomains. OV wildcard shows verified organisation name in certificate details — common for customer-facing SaaS in India.
5. Which Certificate Authorities supply Wildcard SSL through PrecisionTech?
We supply wildcard SSL from multiple global CAs including GlobalSign Wildcard SSL and Sectigo Wildcard SSL. PrecisionTech recommends the best-fit CA for your validation tier, timeline, and budget.
6. How much does a Wildcard SSL certificate cost in India?
Wildcard SSL pricing depends on the CA, validation tier (DV or OV), certificate term, and whether apex domain must be included. PrecisionTech quotes in INR with GST invoice. Contact us for a scoped proposal comparing GlobalSign and Sectigo wildcard options.
7. Is Wildcard SSL suitable for multi-tenant SaaS?
Yes, when all tenants live on subdomains of one registered domain (e.g. tenant1.app.in, tenant2.app.in). PrecisionTech validates your DNS architecture before recommending wildcard versus per-tenant certificates.
8. How many servers can I install a Wildcard SSL on?
Standard wildcard products from major CAs include unlimited server licensing — deploy on web servers, load balancers, and reverse proxies within your environment.
9. Does wildcard SSL cover nested subdomains (two levels deep)?
No. *.shop.example.in covers tenant.shop.example.in but not a.b.shop.example.in. For deeper nesting, PrecisionTech recommends SAN/multi-domain SSL or additional wildcard planning.
10. Does PrecisionTech help install Wildcard SSL on cloud load balancers?
Yes. We deploy wildcard certificates on AWS ALB/NLB, Azure Application Gateway, GCP load balancers, Cloudflare origin setups, and on-premise F5/HAProxy configurations.
11. What encryption standards does Wildcard SSL use?
Modern wildcard SSL certificates use SHA-256 signatures with 2048-bit RSA keys (or ECDSA where supported), compatible with TLS 1.2 and TLS 1.3. Browser and API client trust matches standard single-name SSL from the same CA.
12. Does PrecisionTech help generate a wildcard CSR?
Yes. Wildcard CSRs require the common name
*.yourdomain.com format. We guide CSR creation, private key protection, and SAN list for apex inclusion when needed.13. What happens when my Wildcard SSL certificate expires?
Expired certificates trigger browser security warnings across all covered subdomains. Renewals require fresh domain control (DV) or organisation revalidation (OV). PrecisionTech tracks expiry and initiates renewal before production certificates lapse.
14. Can I upgrade from single-name SSL to Wildcard SSL?
Yes. Upgrading means ordering a new wildcard certificate, completing validation, and installing on all subdomain hosts. PrecisionTech plans cutover to minimise downtime across your subdomain fleet.
15. Is Wildcard SSL better than buying individual certificates per subdomain?
Wildcard is more cost-effective when you operate many first-level subdomains under one domain. If you have only 2–3 fixed hostnames, a SAN certificate may be simpler — PrecisionTech compares total cost during discovery.
16. Does Wildcard SSL work with cPanel and Plesk shared hosting?
Yes, when your hosting plan allows custom SSL installation. PrecisionTech assists with manual wildcard installs and DNS-based domain control validation when AutoSSL cannot issue wildcard coverage.
17. Does Wildcard SSL work with Cloudflare or CDN origin encryption?
Yes. Install the wildcard certificate on your origin server while Cloudflare terminates edge TLS — PrecisionTech configures Full (Strict) SSL modes correctly.
18. How does PrecisionTech invoice Wildcard SSL purchases?
PrecisionTech bills in Indian Rupees with GST invoice for B2B buyers in India. We procure the underlying CA certificate on your behalf and provide deployment support as part of the engagement.
19. Why buy Wildcard SSL through PrecisionTech instead of directly from a CA?
PrecisionTech adds INR billing with GST, India timezone support, DNS architecture review before CSR, multi-CA comparison (GlobalSign vs Sectigo), CSR and chain installation assistance, and renewal tracking — reducing misconfigured wildcard deployments common when ordering cold from a global CA portal.
20. Can I combine Wildcard SSL with EV on the same domain?
Yes. A common pattern is EV SSL on the primary checkout or banking domain plus OV wildcard on subdomains. PrecisionTech architects hostname coverage across validation tiers.
21. Does Wildcard SSL help with SEO or Google ranking?
HTTPS is a lightweight Google ranking signal. Wildcard enables HTTPS across subdomains efficiently — the SEO benefit is encryption coverage, not wildcard versus single-name tier differences.
22. How do I start a Wildcard SSL order with PrecisionTech?
Share your domain, subdomain architecture, validation tier preference (DV or OV), and server platform via precisiontech.in/contact/. We return a scoped CA recommendation and INR quote, then coordinate validation, issuance, and installation through renewal.
