The Trustworthy Software Foundation (TSFdn) aims to collect, organise and share the wealth of knowledge, experience and capabilities that already exist in the UK public and private sectors and in academia about trustworthy software to give people a joined-up, curated view of the information that is available.

Mission Statement

The Trustworthy Software Foundation’s mission is to :


enhance the overall software and systems culture, with the objective that software should be designed, implemented and maintained in a trustworthy manner


The evolution of the TSFdn from the previous Trustworthy Software Initiative (TSI) reflects a continued commitment to promote the importance of Trustworthy Software in the United Kingdom.
