126 Years of reliability goes out into the world.

For 126 years, Nationale Borg has supplied guarantees to companies in the Netherlands and Belgium. During those years we were successful on our own, within our own strict boundaries. But we found the time has come to go beyond those limits and to remove those restrictions. We feel that the fast and chaotic business world of today could do with a little bit more Nationale Borg.

Nationale borg is now a member of Liberty Mutual Insurance.

In 2019 Nationale Borg became part of Liberty Mutual Surety, a unit within Liberty Mutual Insurance, allowing companies outside the Netherlands and Belgium to also ge acquainted with our product: guarantees that are not simply based on blocked funds but on trust in your business.
