Types of SSL certificates: DV, OV, and EV explained

In today's digital world, security is paramount. An SSL (Secure Socket Layer) Certificate is an essential technology that establishes an encrypted link between a web server and a browser. This link ensures that all data transmitted between them remains private and integral. At PlatiniumHost, we understand the importance of protecting your information and that of your users, which is why we offer SSL solutions tailored to every need.

Beyond encryption, an SSL certificate also serves to authenticate the identity of a website. This helps users confirm that they are interacting with the legitimate site and not a malicious imitation. Modern browsers, such as Chrome or Firefox, display a closed padlock and the URL with 'https://' to indicate that a site is secure, which builds trust and improves the user experience. Furthermore, Google and other search engines prioritize sites with SSL, which can positively impact your SEO.

How does an SSL certificate work?

When a browser attempts to connect to an SSL-protected website, an SSL 'handshake' occurs. During this process, the server presents its SSL certificate to the browser. The browser verifies the validity of the certificate and, if it is legitimate, both establish a secure, encrypted connection using cryptographic keys. This means that any data (passwords, banking details, personal information) sent over this connection is protected from interception.

Types of SSL Certificates: DV, OV, and EV

Not all SSL certificates are created equal. There are different types that vary in the level of validation they offer. The three main types are DV (Domain Validation), OV (Organization Validation), and EV (Extended Validation).

1. Domain Validation SSL Certificate (DV SSL)

DV SSL is the most basic and common type of certificate. It is ideal for personal websites, blogs, small businesses, or any site that does not handle sensitive information on a large scale.

• Validation Process: The Certificate Authority (CA) only verifies that you have control over the domain. This is usually done via an email to an administrative address associated with the domain, a DNS record, or by uploading a file to the server.
• Issuance Time: Very fast, often within minutes.
• Level of Trust: Low. It only guarantees that the connection is encrypted and that the domain is legitimate, but it does not provide information about the organization behind the site.
• Visual Indicators: Padlock in the address bar and 'https://'.

2. Organization Validation SSL Certificate (OV SSL)

OV SSL certificates offer a higher level of trust than DV SSL. They are suitable for business websites, online stores, and organizations that need to show their visitors that they are a legitimate entity.

• Validation Process: In addition to verifying domain ownership, the CA performs an exhaustive validation of the requesting organization. This includes verifying the legal existence of the company, its physical address, and its telephone number. Official documents may be required.
• Issuance Time: Generally 1 to 3 business days, as it involves manual verification.
• Level of Trust: Medium. Users can see the organization's name in the certificate details, which adds an extra layer of credibility.
• Visual Indicators: Padlock in the address bar, 'https://', and the organization's name visible in the certificate details when clicking on the padlock.

3. Extended Validation SSL Certificate (EV SSL)

EV SSL certificates are the gold standard in SSL security, offering the highest level of trust and authentication. They are the preferred choice for banks, large corporations, high-volume e-commerce sites, and any entity that handles highly sensitive information and requires maximum user trust.

• Validation Process: This is the most rigorous process. The CA performs an exhaustive verification of the organization's identity, its legal status, its operational existence, and its authorization to request the certificate. A large amount of documentation and manual verification is required.
• Issuance Time: Can take 5 to 10 business days or even longer, due to the depth of the investigation.
• Level of Trust: High. Provides maximum security and the highest level of user trust.
• Visual Indicators: Historically, it displayed a green address bar with the organization's name. Although modern browsers have simplified this to a padlock with the company name visible when clicked, it remains the strongest indicator of authenticity.

Which SSL certificate to choose for your website?

Choosing the right SSL certificate depends on several factors, including the purpose of your website, the type of information it handles, and the level of trust you want to convey to your users.

1. Personal websites, blogs or portfolios:

   A DV SSL is generally sufficient. It provides the necessary encryption and the security padlock, which is good for SEO and basic peace of mind. PlatiniumHost offers free DV SSL in most of its plans.

2. Small and medium-sized businesses, online stores or sites that collect data:

   An OV SSL is highly recommended. It shows your customers that your business is legitimate and that you care about their security. This is crucial for trust in e-commerce and customer data collection.

3. Large corporations, financial entities or sites with high-value transactions:

   An EV SSL is the best option. It offers the maximum level of trust and authentication, reducing the risk of phishing and improving the perception of brand security.
