🔐 GoDaddy SSL/TLS Certificates Review
GoDaddy is one of the most recognized names in web hosting and domain registration, and they also offer a variety of SSL/TLS certificates. Here’s a detailed look at how their SSL offerings stack up:
✅ Pros
-
Brand Recognition & Trust
GoDaddy is a well-known brand, which can instill confidence for some customers, especially non-technical users. -
24/7 Suporte ao cliente
GoDaddy provides round-the-clock support via phone and chat, which is helpful for users needing assistance with installation or certificate management. -
Range of Certificate Types
Offers DV, OV, and EV certificates, as well as Wildcard and SAN/UCC options for multi-domain use. -
Warranty Included
Certificates include warranties ranging from $100,000 para $1,000,000, depending on the level (por exemplo, EV certs). -
30-Garantia de devolução do dinheiro do dia
Users can get a refund if they’re unsatisfied and cancel within 30 dias.
❌ Cons
-
Expensive Compared to Competitors
GoDaddy's SSL pricing is significantly higher than comparable offerings from competitors like Namecheap, ZeroSSL, or even Let's Encrypt (which is free). -
Aggressive Upselling
Users often report aggressive attempts to sell additional products during checkout. -
Confusing UI for SSL Management
The dashboard for managing certificates can be unintuitive, especially for first-time users. -
Lack of Free SSL
Unlike many hosting providers, GoDaddy doesn't offer free SSL (like Let’s Encrypt) with all hosting plans. -
Renewal Pricing is High
Initial discounts may disappear upon renewal, prices can more than double.
💵 Pricing (as of mid-2025)
| Certificate Type | First-Year Price | Renewal Price | Domains Covered |
|---|---|---|---|
| Padrão DV SSL | ~$63.99/year | ~$84.99/year | 1 domínio |
| SSL curinga (DV) | ~$295.99/year | ~$369.99/year | Subdomínios ilimitados |
| OV SSL Certificate | ~$149.99/year | ~$199.99/year | 1 domínio |
| Certificado EV SSL | ~$199.99/year | ~$299.99/year | 1 domínio |
| SAN/UCC SSL (DV) | ~$149.99/year | ~$199.99/year | Até 5 domínios |
Nota: Prices can vary due to promotions or term length.
⚖️ Value Assessment
For beginners or those who want everything from one provider, GoDaddy’s SSL may offer peace of mind due to their support and integration.
Contudo, the pricing is not competitive. You can get equivalent or better protection and features for a fraction of the cost through other CAs or via free options.
GoDaddy SSLs don’t offer unique technical advantages, they use the same encryption standards as most other CAs.
⭐ Final Verdict:
GoDaddy’s SSL Certificates are reliable but overpriced. Suitable for users who want a one-stop solution with support, but not ideal for budget-conscious or technically savvy users.

O que é um certificado SSL/TLS?
Segurança da Camada de Transporte (TLS) and its predecessor, Secure Sockets Layer (SSL), are protocols that enable an authenticated and encrypted connection between computers in a network.
TLS and SSL are often collectively referred to as SSL / TLS. The latest version, TLS 1.3, foi lançado em agosto 2018.
SSL/TLS certificates bind the identity of a website to a cryptographic key pair, que inclui uma chave pública e privada.
SSL certification is the process by which a website's identity is verified and secured through the issuance of a digital certificate.
- o public key, part of the certificate, allows web browsers to establish secure encrypted sessions over HTTPS.
- o chave privada, kept securely on the server, is used to digitally sign content such as web pages and files.
Tipos de certificados SSL
SSL certificates come in several types, each tailored to different security needs and levels of validation:
- Validação de Domínio (DV): Verifies only domain control. Ideal for blogs and small business sites needing basic encryption.
- Validação de Organização (OV): Confirms domain ownership and organization identity. Suitable for businesses wanting to assure customers of legitimacy.
- Validação Estendida (EV): Offers the highest authentication level with visible trust indicators like a green address bar. Best for e-commerce and high-trust transactions.
- SSL curinga: Secures a domain and all its subdomains with a single certificate. Cost-effective for businesses managing multiple subdomains.
- SSL de vários domínios (SAN): Secures multiple domains and subdomains under one certificate. Ideal for complex environments.
Understanding these types—DV, OV, EV, Curinga, and Multi-Domain—helps businesses choose the right level of security and validation to protect users and earn trust.
Qual é a diferença entre HTTP e HTTPS?
o letter “S” in “HTTPS” stands for “secure.” HTTPS is the secure version of HTTP and uses SSL/TLS encryption to protect data in transit.
Sites com endereços HTTPS receberam um certificado SSL legítimo de uma autoridade de certificação autorizada. This ensures that communication between the site and its users is encrypted and authenticated.
Web browsers increasingly label HTTP sites as “not secure” to encourage secure browsing.
Benefits of HTTPS include:
- Data integrity and protection from tampering
- Authentication of the website’s identity
- Improved trust and credibility with users
- SEO advantages from Google and other search engines
Portanto, HTTPS is essential not only for security but also for confiança do usuário e search visibility.
