Secure use of the Internet and e-finance
PostFinance makes security its top priority for financial transactions conducted online. E-finance uses a comprehensive, multi-level security system. Your payments are protected by a multi-level firewall, encryption and our automatic transaction monitoring.
Attempted fraud on the Internet increasingly targets users and their computers. With just a few simple measures, you can protect yourself against the main threats and use e-finance and the Internet securely.
Attempted fraud via e-mail
PostFinance will never contact you by e-mail or telephone asking you to log in or to disclose your security elements.
If you receive an e-mail asking you to log in, to reveal personal data or to open an attachment, it is probably an attempt at fraud. Delete the suspicious message.
Please call our Contact Center immediately if you disclose data or have opened a suspicious attachment.
Your connection to PostFinance is protected with strong encryption. This ensures that nobody can intercept your data. You can tell there is a secure connection from the green text in your browser’s address line. Before you log in, always check that the text is shown in green.
Your connection is automatically protected with the PostFinance apps.
Your access to e-finance is protected with modern, two-factor authentication. As well as your password, the PostFinance Card and card reader or Mobile ID offer additional security. Choose a strong password that includes lower and upper case letters, digits and special characters, and only use it for e-finance.
Invest a few moments of your time now and protect your computer.
Criminals use phishing to attempt to gain access data from Internet users. To do so, they send e-mails with a falsified sender address, or call their victims, pretending to work for banks or software manufacturers. They use the data they obtain either for their own fraudulent purposes, or to sell to third parties.
Protect yourself against phishing by never reacting to suspicious e-mails, but simply deleting them.
Malware is the collective term for programmes that cause damage. This includes viruses for example. If your computer is infected, the hacker can see and modify your data, and initiate credit transfers. Protect yourself against malware by using an up-to-date virus scanner at all times. You should also exercise care when dealing with suspicious e-mail attachments.
Use the online security check available from the Swiss Internet Security Alliance to make sure your system is not affected by malware.
