An SSL certificate ensures secure data transmission through HTTPS and confirms the reliability of the connection.
An SSL certificate allows you to use the SSL protocol for secure HTTPS data transfer. It encrypts the information that is transmitted between the website and the user's computer. If the data protected by the certificate is intercepted, it will take at least a hundred years to decrypt it.
If a website has a missing or expired certificate, browsers will recommend against visiting it. To avoid losing potential users, we recommend installing certificates from trusted certification centers.
Search engines are also committed to Internet security, so sites with SSL certificates are prioritized in their search results. If a site does not have a certificate, it will only be found in searches for specific queries or well below the first page.
An OV- or EV-level certificate will only be issued to a site after thorough verification of the company that owns the domain. Such certificates always include the name of the company, which indicates to the user that the site can be trusted.
SSL Certificates have different levels of validation. When a website owner orders an SSL Certificate, the certification center validates the information provided. Certificates are divided into three levels of validation.
DV (Domain Validation) – certificates with a basic level of validation. The certification center verifies that the applicant has administrative access to the respective domain name.
A DV certificate is suitable for small informational sites that do not accept payments and do not process personal data. These include business card sites, blogs, and news portals. These are the most affordable SSL certificates, and you can be issued one in several minutes.
OV (Organization Validation) certificates are issued for domains owned by an organization. The certification center checks the information about the company in the online directory of the state registration authority and in various other directories, to ensure that such a company really exists and that the site belongs to it. Such a certificate will contain the legal name of the company.
OV certificates are suitable for online stores and sites offering personal accounts or paid services. An OV certificate cannot be issued to an individual.
EV (Extended Validation) certificates indicate that a website is of the highest reliability. The validation takes about 10 days and involves manual verification of the company’s information and contact details. Once verified, the contacts are added to the site's certificate. This information is visible to all site visitors by opening the certificate details.
EV certificates are suitable for large organizations and brands for which reputation is crucial.
Yes, but there are a few ways to save money. Read on.
Wildcard certificates protect the primary domain and a range of sub-domains thereof specified at the time of order. For example, you can protect the domains example.com, mail.example, and sale.example with a single certificate by specifying *.example.com. This will protect all of the site’s subdomains (that is mail.example.com, but not my.mail.example.com. To protect such domains, you will need to already have the *.mail.example.com range).
One multi-domain SAN certificate protects several different domain names, for example primer.ru, example.com or subdomains of different levels: mail.example.com and my.mail.example.com. The full list of values is specified when ordering a SAN certificate.
One SSL Wildcard certificate can protect several domains with different ranges at once. This certificate can be used to protect domains such as *.primer.ru, *.mail.example.com, and *.site.net
