Market challenges

Once reserved for merchant/e-commerce websites, the secure HTTPS protocol is becoming widespread. This can particularly be observed since February 2017, when Google began to display the words “not secure” on simple unsecured HTTP sites. To make exchanges secure, SSL certificates are the safest and the most efficient way to secure a space online. This ensures total data confidentiality on a website.

Our solution: Internet security

Protect all confidential data and give legal value to all documents used

Tessi’s Internet security solution aims to protect all confidential data and give legal value to all documents used. With the CERTIGNA SSL offer, you set the desired type of web security (Organisation Validation (OV), Extended Validation (EV)) and send a clear message to your customers.

Not only are you providing them with sufficient proof that your website is legitimate and honest, but they can also browse and transfer their data to the site with confidence. CERTIGNA SSL certificates use the best technology to exchange all kinds of data efficiently and without risk, making them ideal for sales websites, portals, e-mail, FTP or VPN servers.
