The difference between DV and OV certificates

We know that the SSL-certificates can be divided into three types: DV, OV and EV. In this article, we will focus on the first two types of certificates, DV and OV. We will explain how they differ and when you should choose DV over OV.

DV-certificates (Domain Validation). This is the most basic level of SSL validation. The Certification Authority (CA) only ensure that you are the owner of a specific domain using the information contained in the WHOIS. Naturally, this type of certificate enables secure data encryption on your site, but it does not verify that you are the owner of a legitimate business. It is legitimate, and, most importantly, it is a very quick solution to protect your site using HTTPS. Customers seeing the padlock in your browser will have more trust in your site than before, because the padlock is a recognised sign of legitimacy.

Example of a DV certificate:

A DV certificate is fine where security is not a concern: however, attackers can also use DV-certificates on phishing sites. Unsuspecting users see the trusted pad lock and enter their personal data on the site which can then fall into the hands of fraudsters. The fact that the data channel is secured does not necessarily mean that the data will go to the right people. A user needs to be sure that the site belongs to a legitimate company if they are to make a purchase or input important information. 

For this reason, if security is a necessity for your site, we recommend an OV-certificate.

OV-certificates (Organisation Validation) are required for companies and organisations where users must enter sensitive information (credit card numbers, contact information, etc.).In particular, they are useful for e-commerce sites or online sales. An OV-certificate authenticates the owner of the site and requires legitimate business information for that company. The validation process for these certificates is longer and more detailed. The Certification Authority not only verifies the fact that you own the domain, but also the fact that you are the owner of the company. The company must be in a business registry database and in a trusted online directory (for example, dnb.com). Fraudsters cannot get an OV certificate because their organisation cannot be validated. The main advantage of getting an OV-certificate is that your company will be listed on the certificate.

Example of an OV-certificate:

  • You need to protect sensitive user data
  • You want to display your company name on a certificate (provides more trust amongst users)
  • You are planning to expand the business and grow it to a new level
  • You want people to know that the site is a legitimate organisation, and not a phishing site

You should think about switching from a DV-certificate to an OV-certificate, if:
