SSL (TLS) certificates

Protect website data exchanges

SSL certificates are fundamental to security and should be managed using the best tools

SSL certificates are a crucial tool for securing websites.

Installing an SSL server certificate enables the implementation of TLS protocol (transport layer security). TLS is a standard solution for guaranteeing the security of online transactions, and has two key security mechanisms:

  • Secure channel: all data transferred between the website and end user is encrypted
  • Server authentication: the user can check the website's authenticity and the identity of the organisation managing it

Actalis not only offers a comprehensive range of SSL certificates, but also provides its enterprise customers with centralised, automated management solutions for their security certificates.

Actalis SSL certificate solutions: key benefits

We offer all categories (DV, OV, EV) and classes (Single Domain, SAN, Wildcard) of SSL certificate. Each one encrypts communication between the end user and the website, displaying the secure connection icon in the browser address bar and removing security warnings while browsing. For enhanced trust, OV and EV certificates certify the identity of the company or organisation that manages the website. EV certificates also include the company name in the certificate details.

Problem reporting

To report problems related to SSL Server or Code Signing certificates issued by Actalis, you may:

  • send an email to [email protected] (we commit to timely read that mailbox during working hours only),
  • or - IN EMERGENCY ONLY - call our telephone number +39 0575-050.376 (please keep in mind that we do not provide technical support at that number: we only take charge of problems related to already issued certificates).
Warning: customer support is not provided through the phone number and the email address mentioned above. Support requests received via those channels will be ignored and will not receive an answer.

By "problems" we mean events or situations that - if confirmed - justify an urgent action by Actalis, such as the compromise of the owner's private key, a court order, the criminal use of the certificate (e.g. for phishing, or malware distribution), and so on. Depending on the problem severity, Actalis may decide to revoke the certificate, as provided for in the CPS.

You must provide at least the following information, when reporting a problem to Actalis, or your alert will be ignored:

  • your full name
  • your phone number
  • description of the alleged problem
  • enough information to identify the offending certificate

If the problem reporter claims to represent the certificate holder organization, he/she must prove that by answering some questions.

Reminder: if you are the certificate owner, you can at any time revoke your own certificate, by yourself, via the web interface at, after logging in with the credentials that have been sent to you at certificate issuance time.

Frequently asked questions

SSL (Secure Sockets Layer) is the name of the protocol used to establish secure communication between a Server and a Client, without data (such as passwords, personal details and credit card numbers) being intercepted, tampered with or falsified. To ensure secure browsing, where the data is protected, the appropriate SSL Server certificate needs to be installed, issued by a trusted third party (Certification Authority).
SSL Certificates are available in 3 categories (Domain Validation, Organization Validation and Extended Validation), with different types of validation (Single Domain, Wildcard and SAN).
The Domain Validation SSL Certificate (DV) validates ownership or control of the domain by the applicant. A DV SSL Certificate contains the domain's common name and can be issued on a Single Domain, Wildcard, and SAN basis.
The Organization Validation (OV) SSL Certificate requires the same checks as for the DV Certificate, plus verification of the company that owns the domain. The OV SSL Certificate also contains information about the applicant's organization and can be issued on a Single Domain, Wildcard, and SAN basis.
The Extended Validation SSL Certificate (EV) is the certificate offering the highest level of reliability. In addition to the checks carried out for the OV, for an EV SSL certificate, the Certification Authority carries out more in-depth checks, ensuring, for example, that the request comes from a person authorized to represent the organization. It can be issued on a Single Domain and SAN basis.
An SSL Certificate with Single Domain validation is valid for just 1 domain name (for example "domainname.TLD").
An SSL Certificate with Wildcard validation is valid for 1 domain name (for example "domainname.TLD") and all of its subdomains, usually in the format *.domainname.TLD (for example "shop.domainname.TLD", "login.domainname.TLD", etc.).
An SSL Certificate with SAN validation (Subject Alternative Name) is valid for a maximum of 5 different domain names (for example "domainname.TLD", "domainname1.TLD", "domainname2.TLD", etc.).
