What is an SSL certificate?

SSL / EV Certificates

An SSL (Secure Sockets Layer) certificate, also known as Transport Layer Security (TLS), is created using a internet communications security protocol. An SSL certificate certifies a company’s identity and ensures that data exchanged through the internet is encrypted.


Using SSL mode enables internet users to identify the owner of the website they are visiting, as well as confirming that this owner really existed on the date on which the certificate was issued and ensuring that data exchanged through the site is encrypted.

The main purpose of an SSL certificate is to authenticate the company that uses it. Authentication is performed by a reputable certification authority which issues keys to set up encrypted connections, in order to secure:

  • Web pages,
  • Forms that display or send sensitive or confidential data such as bank card numbers or private data (medical information, personal contact details, passwords etc.),
  • Company data.

Using an SSL certificate ensures that all of this data is sent in a secure and encrypted environment. Setting up an SSL system will reassure web users and improve the efficiency of your website (form filling, online purchases etc.)

Another reason to install an SSL certificate is Article 34 from the CNIL (French Data Protection Authority – Commission nationale de l’informatique et des libertés), which states that IT professionals must secure databases and personal or financial data during transit.

This law states that the data processing manager is personally responsible for ensuring the security and confidentiality of data in order to uphold the privacy of the persons in question. It is therefore crucial to protect your data communications.

SSL protocol

The SSL (Secure Sockets Layer) protocol is based on complex symmetric and asymmetric encryption algorithms (public and private key cryptography). It is used to set up a session between a web browser and a server hosting a secure website.

The SSL certificate enabling this session to be opened is issued by a certification authority, after the authority has completed a strict audit corresponding to the authentication factor by which the certificate in question is covered.

How an SSL certificate works

The session is essentially opened in the following way: after your request has been sent, your internet browser asks the web server that you are going to connect to to authenticate itself.

The server provides a copy of its SSL certificate in response. On receipt of the cert the browser analyses its compliance and checks that it has not been revoked.

When this check is complete, the browser sends a positive response to the server. Once the browser has issued its acceptance, the web server validates the process and sends a digital signature to confirm the launch of the session.

It is only once this process has been finalized that the session is active and transactions are encrypted.


choisir un certificat SSL

The choice of SSL certificate depends precisely on which services need to be secured and authenticated, together with the technical and application environment in which the certificate will be deployed.

The factors used to select an SSL certificate are linked to the services need to be secured and authenticated, together with the technical and application environment in which the certificate will be deployed.

It is crucial to fully analyze your needs, objectives sought, and the technical environment in which the certificate will be installed according to these significant constraints. All of these elements will be instrumental in putting together a request to submit to the chosen certification authority.

When you have established the prerequisites, we can offer you SSL certificates to cover the services you wish to secure and authenticate. We can then submit your request to the certification authority.

Website category

On what type of website do you wish to set up a secure and authenticated https connection? Is it an e-commerce site, information, statistics etc.?

Securing a single domain

Will the certificate secure a single domain (www.)domain.com or several websites linked to the sub-domains of one primary domain (*.domain.com) ?

In the latter case, opt for a Wildcard or multiple site certificate.

Securing data

What type of data do you wish to secure (login information, medical data, forms etc.) ?

Which authority should I choose?

Does the certificate need to be issued by a well-known authority, or is the concept of a trusted third party not crucial?
