During the transfer between customer computer and the financial institution’s server, data are encrypted, making it impossible for third parties to view them.
Encrypted data transfer
The e-banking systems employed by Swiss financial institutions are among the most secure worldwide. Customer data are protected from undesirable third party access during transfer by implementing various security precautions. A digital SSL certificate allows for checking the e-banking server's identity.
Data between the e-banking server and the customer computer are encrypted using at least a 128 bit key both ways. This modern and widely used technology guarantees a high standard of security, protecting the data recorded and transferred from manipulation. Encryption takes place automatically, without customers having to do anything special or needing to install any special software.
