Mission

Software must become safer.

Software has been built badly for the past decades, and our industry is spending most of its time patching the leaks.

Our lives have become highly digitalized and we depend heavily on digital infrastructures; on a daily basis we are faced with the consequences of unsafe software and poorly protected data. It is time to make software safer.

At Tweede golf, we believe that the design of safe and secure software is the responsibility of all software builders; freelancers, agencies and big tech. Safety, security, and reliability thus become the domain of software makers, not just that of pen testers and consultants.

An ounce of prevention is worth a pound of cure - even more so in software.

Trifecta Tech Foundation

Over the years, Tweede golf has worked for clients on both commercial software and on open-source software. This latter category includes projects such as sudo-rs and our time synchronization work.

In 2024, the owners of Tweede golf created a non-profit, Trifecta Tech Foundation, as the new long-term home of our open-source projects that serve the public benefit.

While there are no legal ties between the two organizations, Tweede golf is committed to the future of Trifecta Tech Foundation and continues to support them through in-kind and financial donations.

Trifecta Tech Foundation's mission is to make the digital world safer for everyone by creating robust building blocks that reduce attack surface.
