SSL certificates are divided into three main types: Domain Validation (DV), Organization Validation (OV), and Extended Validation (EV). Each certificate type offers different levels of validation and security, which affect the safety and trustworthiness of a website. The choice of the right certificate depends on the website’s purpose and the required level of trust.

What are the types of SSL certificates?

SSL certificates are divided into three main types: Domain Validation (DV), Organization Validation (OV), and Extended Validation (EV). Each type has its own specific features and purposes that impact the security and reliability of a website.

Types Validation Level Purpose
DV Basic Simple websites
OV Intermediate Business websites
EV High Finance and e-commerce

Domain Validation (DV) certificate

A DV certificate is the basic form of SSL certificate that only verifies the ownership of the domain. This certificate is quick and easy to obtain, as it requires only email verification or a change to DNS records.

DV certificates are best suited for personal blogs or small websites that do not handle sensitive information. They provide basic encryption but do not instil as much trust in users’ eyes as other certificates.

Organization Validation (OV) certificate

An OV certificate offers higher security as it requires verification of the company’s or organisation’s background information. This process includes checking the company’s name, address, and phone number, which increases trust with customers.

OV certificates are recommended for businesses that want to demonstrate to their customers that they are legitimate and trustworthy. They provide better protection than DV certificates and are often used in online stores and services that handle user data.

Extended Validation (EV) certificate

An EV certificate is the highest possible validation level among SSL certificates. It requires thorough verification, including the company’s legal status, ownership, and physical location. This makes EV certificates highly reliable.

EV certificates often appear as a green address bar in browsers, which enhances user trust. They are particularly important in online banking and other critical business operations where security is a primary concern.

Why choose a DV, OV, or EV certificate?

Why choose a DV, OV, or EV certificate?

DV, OV, and EV certificates provide different levels of validation for website security. The choice between these certificates depends on your needs, such as the nature of your business and customer relationships.

Advantages and limitations of DV certificates

A DV certificate (Domain Validation) is the fastest and easiest way to obtain an SSL certificate. It ensures that the applicant owns the domain but does not verify the identity of the business.

  • Advantages: Quick issuance, low cost, easy to obtain.
  • Limitations: Does not provide verification of the business identity, which may reduce customer trust.

A DV certificate is well-suited for personal sites or small businesses that do not handle sensitive information. However, if it is important for customers to know who they are dealing with, a DV certificate may not be sufficient.

Advantages and limitations of OV certificates

An OV certificate (Organization Validation) offers deeper validation than a DV certificate. It requires the business to undergo a more detailed examination, which increases trust with customers.

  • Advantages: Verifies the business identity, increases customer trust, suitable for business websites.
  • Limitations: Longer issuance process, higher costs compared to DV certificates.

An OV certificate is a good choice for businesses that want to show their customers that they are reliable and serious. This certificate is particularly useful for online stores and services that handle customer data.

Advantages and limitations of EV certificates

An EV certificate (Extended Validation) provides the highest level of validation. It requires thorough verification and visibly confirms the business identity on the website.

  • Advantages: Highest customer trust, visible green address bar or company name in the browser, excellent choice for large companies.
  • Limitations: Most expensive option, long issuance process, may not be necessary for small businesses.

An EV certificate is particularly beneficial for companies that handle large amounts of sensitive information or operate in financial services. It can significantly enhance customer trust and brand reputation.

How to choose the right SSL certificate?

How to choose the right SSL certificate?

The choice of the right SSL certificate depends on the type of website, its purpose, and the required level of trust. Certificates such as DV, OV, and EV offer different levels of security and requirements that affect budget and cost factors.

Type of website and purpose

The type of website determines what kind of SSL certificate is needed. For example, personal blogs or small business websites can often use DV certificates, while larger companies or online stores may require OV or EV certificates.

The purpose is also important. If the website handles sensitive information, such as payment details, an EV certificate may be the best choice as it offers a higher level of trust.

Choose a certificate that meets the needs of your website and user expectations. For instance, if your site is intended for customer service, an OV or EV certificate may enhance customer trust.

Budget and cost factors

Budget is a key factor in choosing an SSL certificate. DV certificates are generally the most affordable, with prices ranging from a few tens to several hundred euros. OV and EV certificates are more expensive, with prices potentially reaching hundreds of euros per year.

Cost factors also include the certificate’s validity period and any additional services, such as website audits or customer support. Compare prices and services from different providers before making a decision.

Remember that the cheapest option is not always the best. Investing in a high-quality certificate can save money in the long run, especially if your website handles sensitive information.

Trust level needs

The level of trust is an important consideration when choosing an SSL certificate. A DV certificate provides basic protection but does not verify the organization’s identity. An OV certificate increases trust as it requires verification of the business.

An EV certificate is the best option if you want to maximise user trust. It requires thorough verification and displays a green address bar in the browser, which enhances users’ sense of security.

Choose a certificate that meets the trust level needs of your website. If your customers are concerned about data security, investing in a higher-level certificate may be wise.
