Information security at Swiss Post
Our pledge: digital postal secrecy

Rich Content Section

The same principle that has long since applied to physical postal items also plays a key role in digital data processing at Swiss Post, namely ensuring the highest possible level of security and discretion when handling customer data.

Both technological developments and cyber threats are analyzed on an ongoing basis. The detection of vulnerabilities at an early stage allows a response to be made quickly, before a risk to the stored data arises.

Swiss Post operates its own two data centers in Switzerland, which provide a first-class hosting environment for data and which are protected by several layers of security.

The sophisticated IT systems, along with technical, construction and organizational measures and a responsible approach to handling data allow Swiss Post to keep its performance pledge and provide the best possible protection for the data entrusted to it.
