With an SSL certificate, you provide your website visitors secure and verified data transmission. This creates trust with your visitors and ensures that their data does not fall into the wrong hands. At netcup you will find a large selection of different certificates.

SSL certificates differ from each other in the following points: Browser acceptance, type of validation and the number of domains that can be protected with a certificate. In general, the following rule of thumb applies: the less a certificate costs, the less time is available for validation. Certificates with too simple a validation are issued quickly, but are often insecure. Therefore, these certificates are not accepted by every browser. In particular, browsers on mobile devices (such as iPad, iPhone, Android devices, etc.) display a warning when a website with an insecure certificate is accessed.

Domain validation is the simplest way to issue an SSL certificate. With this type of validation, the CA (certificate issuing authority) sends an activation link to an email address that can only belong to the owner of the domain (e.g. webmaster@domainname.tld). The owner of the domain can then agree to the certificate being issued via the activation link.

Organization validation is much more secure. Here the CA checks the existence of the certificate holder. The certificate confirms the identity of a company, not just the authenticity of the domain. By clicking on the seal or lock, customers are able to check that they are not the victim of a phishing attack.

Extended validation currently offers the most secure form of validation. These certificates are only issued by the CA after a strict check. By clicking on the seal or lock, the company name is displayed in the certificate. EV certificates thus create even more trust and clear security for visitors. Certificates with EV are used for the exchange of strictly confidential information, e.g. by financial institutions.
