There are several types of SSL certificates available, and the right choice can vary depending on the specific needs of your website. The main differences between these certificates can be found in three main areas:
- Coverage: The number of domains that are covered.
- Validation: What information is verified.
- Brand: The party that issues the SSL certificate.
| Validationmethod ╲ Coverage | Single Domain | Multiple Domains | Wildcard |
|---|---|---|---|
| Domain Validated (DV) | DV Single Domain | DV Multiple Domains | DV Wildcard |
| Organization Validated (OV) | OV Single Domain | OV Multiple Domains | OV Wildcard |
| Extended Validation (EV) | EV Single Domain | EV Multiple Domains | Not Available |
SSL differences based on coverage
Single Domain SSL Certificates
A single domain SSL certificate, as the name suggests, is valid for one specific domain. This means that encryption and authentication only apply to the exact website for which the certificate is issued. Subdomains are not covered by this type of certificate.
It’s important to understand that an SSL certificate is only valid for the specific domain(s) included in the certificate. A single-domain certificate, for example, 123ssl.nl, is valid exclusively for that one domain.
Multi-Domain SSL Certificates
For organizations that manage multiple websites, Multi-domain SSL certificates can be an efficient solution. With a single certificate, multiple domain names can be secured. This means that you don’t need to apply for a certificate for each separate website, which can save both time and money.
In the case of the domain 123ssl.nl; suppose you have other domains besides 123ssl.nl, such as 123ssl.be. By using a multi-domain SSL certificate, you can secure all these domains with a single certificate.
In a multi-domain SSL certificate, you can also include one or more wildcard certificates.
Wildcard SSL Certificates
Wildcard SSL certificates are designed to secure an unlimited number of subdomains of a website. Thus, with a single wildcard certificate, you can secure the main domain and all associated subdomains.
In the case of the domain 123ssl.nl; suppose you have other domains besides 123ssl.nl, such as shop.123ssl.nl and blog.123ssl.nl. By using a wildcard SSL certificate, you can secure all these domains with a single certificate.
SSL differences based on validationmethod
We have already discussed how an SSL certificate ensures the security of a website. But what can you actually state with certainty when you see that a website is secured with an SSL certificate? This depends on the type of validation that has been applied.
Domain Validated (DV) Certificates
Domain Validated, or DV certificates, are the most basic form of SSL certificates and are the most common. The verification for this type of certificate involves the applicant proving they own the domain for which the certificate is being requested. This is often done through file validation, DNS record, or an email. A DV certificate encrypts the communication between the user’s browser and the website, but it does not provide additional information about the organization behind the website.
This type of certificate merely indicates that the visitor is connected to the domain they see in the address bar. The certificate does not specify which organization is behind this website.
Organization Validated (OV) Certificates
A step further are the Organization Validated, or OV certificates. These certificates require not only that the applicant owns the domain but also that the organization is legitimate. The process for obtaining an OV certificate involves a stricter check where official documents must be submitted to confirm the organization’s identity. The name of the organization is displayed in the browser’s address bar, instilling trust in the website’s users.
Extended Validation (EV) Certificates
Extended Validation (EV) certificates represent the highest level of trust and security a website can achieve. These certificates are a powerful tool in the fight against phishing as they provide a clear indication that a site is legitimate and secure. The verification procedure for obtaining this type of certificate is intensive and thorough.
The procedure includes a check of domain ownership, an investigation into the organization’s legitimacy, a thorough review of business operations, and even verification of the organization’s physical presence. Therefore, EV certificates are not just proof of domain ownership but also a confirmation of the integrity and reliability of the organization behind the website.
EV certificates are particularly useful for websites that process sensitive information, such as financial institutions, banks, or e-commerce sites. They help build trust with users by confirming that the website is legitimate and secure.
It is important to note that the application for such a certificate can take some time, given the extensive validation required. Typically, this process takes about 3 to 5 days, although this can vary depending on the specific circumstances.
SSL Certificates Based on Brand
There are various brands or issuers of SSL certificates, including Comodo, Symantec, Thawte, GeoTrust, and DigiCert, to name just a few. Each brand has its own characteristics, pricing, and validation levels.
Some brands, such as Symantec, are known for their stringent validation procedures and thus enjoy a high degree of trust and recognition in the industry. Others, like Comodo, offer a wide range of certificates at competitive prices, making them popular among small and medium-sized businesses.
It’s important to note that regardless of the brand, each SSL certificate provides a certain level of security. The choice of brand often depends on factors such as budget, the required validation level, and the specific needs of your website. It’s always recommended to do thorough research before making a decision.
