Secure Swiss Finance Network

Secure Swiss Finance Network

For secure, flexible and resilient data communication

A Key Contribution to the Fight against Cyber Risks

Secure access to infrastructure services is essential for a smoothly functioning Swiss financial center. Data exchange among participants has to meet the very highest requirements regarding security and availability in the fight against cyber risks. The Secure Swiss Finance Network (SSFN) is a controlled and secure network launched by the Swiss National Bank and SIX.

The SSFN allows all connected users in the Swiss financial center to communicate securely with SIX, other financial market infrastructures and also with each other. The network is based on the SCION technology developed by ETH Zürich, thanks to which a new level of security, performance and functionality in data exchange processes is achieved.

Initiate the switchover to SSFN now

At the end of September 2024, SSFN will replace the current communication network Finance IPNet. All infrastructure services of SIX that currently use Finance IPNet as a gateway have been prepared for the connection via SSFN. SIC, euroSIC, SECOM (through the webMAX and CCLink interfaces) and ATM Monitoring are already accessible via SSFN.

We advise all SIX customers with a Finance IPNet connection to initiate all the necessary steps for switching over to SSFN as soon as possible.

About This Service

How Does SSFN Work?

The SSFN is based on the SCION technology developed by ETH Zürich and, as a network, acts as a standalone isolation domain (ISD) with its own trust root configuration (TRC) used exclusively by the Swiss financial sector.

The cooperation of the telecommunications providers (providers of SCION connections) enables data communication within SSFN. SIX issues the certificates required for participation. SSFN allows a precisely defined group of users (network participants) to exchange data with each other.
Isolation domains like SSFN combine the benefits of private and public networks. The cooperation and networking of several telecommunications providers increase robustness against failures and attacks. This is because the status of every possible connection is known at all times. If the connection in use fails, the next best is automatically activated based on the rules, and data exchange continues on this connection – normally without any disruption to the application session.

Establishing a SSFN Connection

The latest webinar supports organizations in setting up a SSFN connection
and using SSFN as a gateway to the services from SIX.

Steps to Use

The minimum requirements for using SSFN are a SCION connection, a SCION gateway and the SSFN certificate. For reasons of redundancy, SIX recommends connecting via two different telecommunications providers.

Note: Experience shows that responsibility for setting up and operating an SSFN connection lies primarily with network specialists.
