How security is shown online

Standard SSL certificates provide general basic protection. In all browsers, this is indicated through a lock-icon in the browser bar, sometimes accented in green and with the addition of the text “secure”. The URL begins with “HTTPS”, indicating that the website data is encrypted.

Extended SSL Certificates are characterized by a high level of validation, for which the authenticity of your business will be verified. In the browser bar this is highlighted by the lock symbol and the distinctive green color. It is also clearly visible that the certificate has been issued on your company name.

  • Encrypted online transaction of confidential data
  • Certificate with explicit authentification information to certify reliability

Secure Socket Layer (SSL) is a protocol that was developed to enable secure data transfers via Internet. SSL certificates, amongst others, are used for online banking or shop solutions. All browsers like Internet Explorer, Netscape, Mozillla Firefox and Safari etc. support this standard.

SSL offers encrypted connections between servers and clients with certificates complying with the X.509 standard – and additionally safeguards message integrity. SSL uses the public-key method to do this. Data is encoded with a public key and can then only be decoded with a private key.
