An SSL certificate is a unique digital signature of a website for secure data transmission.
An SSL certificate is a digital signature of the website which guarantees secure connection between the server and the user's browser. It provides reliable data protection — the information is transmitted in encrypted form using the https protocol and can only be decrypted using a special key known only to the certificate holder.
Security and privacy
The security certificate confirms the authenticity of the site and encrypts data transmission, ensures its safety and impossibility of interception.
Compliance with the law on personal data
The owner of a resource that collects even minimal information about its users must ensure its security. One of the security measures is SSL.
Higher ranking in search results
SSL certificate plays an important role in SEO-promotion: sites with https have higher positions in search engines.
Confirming website trustworthiness in browsers
Since 2017, Mozilla Firefox and Google Chrome have only labeled sites with SSL certificates as trustworthy.
SSL certificates differ in the level of validation of the applicant's data before issuance and in the number of domains and subdomains for which they can be used.
Usually, certificates are issued for a single domain (sometimes with or without www).
Certificates allowing protection of multiple domains belong to the SAN category. Buying such a certificate will cost less than a few standard ones and is a suitable solution for companies with multiple sites. Certificates of Wildcard category are used for protection of unlimited number of subdomains.
SSL certificates are divided into three groups according to their level of validation:
There are also separate SSL certificates for developers — Code Signing SSL. They allow to sign software, guarantee the authenticity of the source and the integrity of the software.
For individuals and sole proprietors only SSL Certificates with Domain Validation are issued, they only require proof of domain ownership. They are the easiest certificates to obtain, and their issuance rarely takes more than a day. They provide a sufficient level of encryption during data transmission and positively influence website positioning in search engine results.
All types of SSL certificates are available for legal entities, therefore, before buying, it is important to determine whether the product you choose is suitable for your needs.
To purchase an SSL certificate for the website, choose the appropriate option, confirm and pay for the order. We will send detailed instructions on how to order and install the certificate to the email specified in the contacts of your agreement.
If you have a large number of subdomains, it makes sense to use the Wildcard category certificate. For example, this will be relevant for development purposes, where subdomains are often used for testing, or for sites with a branched structure - subdomains help make navigation more convenient.
Wildcard SSL differs from other certificates in that it protects both the primary domain name and an unlimited number of subdomains.
SSL Certificate configuration
We will perform all operations for you to successfully install the certificate.
An SSL certificate is a digital signature for your website. It guarantees a secure connection between the server and the user's browser.
When it is used, information between the website and browser is transmitted in encrypted form and can only be decrypted using a special key that is part of the certificate.
Even if the site name is entered correctly in the browser, attackers can spoof it in whole or in part (for example, by intercepting traffic in public networks - subways, cafes or business centers). Thus fraudsters can gain access to customer data, place their banners or payment forms on your site.
SSL certificates exclude the possibility of such spoofing - by checking the certificate, the user can be sure that the domain is hosting the exact site that should be there, not a duplicate.
In addition, the https certificate allows the user to verify who the owner of the site is. This means that the user can verify that he/she is visiting the site of the desired organization and not the site of its duplicate.
Another important function of SSL certificates is encryption of your Internet connection. An encrypted connection is necessary to prevent possible theft of sensitive data during transmission on the Web.
You can actually install a free certificate, but it's more reasonable if you want to test a new site or save money at first. If you have a full-fledged business site, it is better to install a paid certificate: it will provide a high level of protection, compatibility with browsers, guaranteed solution against hacking, and will have full support.
There are several questions to answer when choosing a certificate:
1. How many domain names you want to protect: one or more.
2. What kind of service you want to protect:
a. if you protect financial data, it is better to use a certificate with extended validation,
b. to protect customer data in your online store, it is better to use certificates with organization and domain validation.
After the payment, the order for certificate issuance goes to the certificate authority for processing. Verification of submitted data may take some time (usually not more than two days).
Once the certificate has been issued, a notification will be sent to the email address specified during ordering, with a link to the "Manage your account" section page where the certificate can be obtained.
