What Is an SSL Certificate and Why Does It Matter?
An SSL (Secure Sockets Layer) certificate — now technically using TLS (Transport Layer Security) — is a cryptographic protocol that encrypts data exchanged between a web browser and a server. Installing an SSL certificate enables HTTPS and displays the padlock 🔒 icon, which matters for three key reasons:
- Security — Data transmitted between users and your website is encrypted, preventing interception
- SEO — Google has used HTTPS as a ranking signal since 2014
- Trust — Modern browsers display "Not Secure" warnings for sites without SSL
SSL certificates are issued at different validation levels by Certificate Authorities (CAs). These levels — DV, OV, and EV — determine how thoroughly the CA verifies the applicant's identity, not the strength of encryption.
SSL DV (Domain Validation) Explained
A DV certificate validates only that the applicant controls the domain. No organization information is verified. The CA confirms ownership through one of three methods:
- Email verification (admin@ or webmaster@ the domain)
- DNS record (add a specific CNAME or TXT record)
- HTTP file-based verification (upload a file to your server)
DV certificates issue within minutes and are the most affordable SSL option. They provide the same encryption strength as OV and EV certificates.
SSL OV (Organization Validation) Explained
An OV certificate validates both domain ownership and the organization's identity. The CA verifies that the organization legally exists, has a valid business address, and can be reached by phone.
Documentation Required for OV
- Legal company/organization name (matching business registration)
- Valid business address
- Working phone number
- Business registration documents (when required)
Organization details are embedded in the certificate and visible to users who inspect the certificate in their browser. OV certificates typically issue in 1–3 business days.
SSL EV (Extended Validation) Explained
An EV certificate undergoes the most rigorous validation process, following CA/Browser Forum EV Guidelines. The CA verifies the organization's legal existence, operational status, and the identity of the authorized signatory.
EV Validation Steps Beyond OV
- Legal status verification (company properly registered under applicable law)
- Domain rights confirmation
- Verification of active business operations
- Identity of the authorized signer confirmed
- Cross-check against third-party databases (e.g., Dun & Bradstreet)
SSL Wildcard Certificates
A Wildcard SSL certificate (*.example.com) covers the main domain and all first-level subdomains in one certificate — mail.example.com, shop.example.com, blog.example.com — without needing separate certificates for each subdomain.
Wildcard describes coverage scope, not validation level. You can have a Wildcard DV or Wildcard OV certificate. AsiaGB offers Wildcard DV SSL at 5,000 THB/year.

Which SSL Type Is Right for Your Business?
The right SSL certificate depends on your website's purpose and the level of trust you need to establish with visitors.
Choose DV when
- Running a personal blog or website that doesn't process payments
- Building a portfolio, prototype, or staging environment
- Budget is a primary concern
- You need HTTPS quickly (minutes vs. days)
Choose OV when
- Operating a business website where showing organizational credibility matters
- Running an e-commerce store that handles customer data
- You want visitors to be able to verify your organization in the certificate
- Compliance requirements specify verified organizational identity
Choose EV when
- Operating as a financial institution, bank, or payment processor
- Running a government or large enterprise website
- Your compliance policy requires EV-level validation
- Your site is a common phishing target and you want maximum trust signals

Frequently Asked Questions
Does SSL type affect encryption strength?
No. DV, OV, and EV certificates all use the same encryption strength (2048-bit RSA or 256-bit ECC). The difference is only in how thoroughly the applicant's identity is verified by the CA before issuance.
Which SSL certificate is best for a personal blog?
A DV SSL certificate is sufficient for personal blogs or small websites. Starting from just 1,000 THB/year, it provides full HTTPS protection and issues within minutes.
Should an e-commerce site use OV or EV SSL?
E-commerce sites should use at minimum an OV certificate. Displaying verified organization information builds customer trust and can improve conversion rates, especially for higher-value products.
How long does an OV SSL certificate take to issue?
OV certificates typically take 1–3 business days as the CA must verify organization information. DV issues within minutes and EV takes 3–7 business days.
Is EV SSL still worth it in 2026?
Yes, especially for financial institutions and banks. While modern browsers no longer show a green address bar, organization details remain visible in certificate information and EV significantly reduces phishing risk for high-value targets.
What is a Wildcard SSL certificate?
A Wildcard SSL (*.example.com) covers your main domain and all first-level subdomains in one certificate. It can be DV or OV validated. AsiaGB offers Wildcard DV SSL from 5,000 THB/year — cost-effective if you have multiple subdomains.
Summary: Choosing the Right SSL Certificate
The difference between SSL DV, OV, and EV lies in identity verification depth, not encryption strength:
- DV (1,000 THB/yr) — Domain only, best for blogs and personal sites, issues in minutes
- OV (4,000 THB/yr) — Domain + organization, best for SME and e-commerce, builds trust
- EV (7,000 THB/yr) — Highest verification, best for banks and financial institutions
- Wildcard DV (5,000 THB/yr) — Covers all subdomains, cost-effective for multi-subdomain setups
