HH Partners provides Vaisala with automated open source compliance

HH Partners provides services on open source compliance and related tools to Vaisala Oyj.

“We’ve used HH Partners’ open source compliance services via our membership in the Validos association for over 10 years,” says Petri Sairila, Open Source Officer at Vaisala. “Now we have piloted compliance tooling automation for embedded Linux projects. The benefits of automation proven by the pilot are the reduction of manual work and increase in the quality and speed of open source compliance.”

“Since 2015, the amount of open-source software used in enterprises has skyrocketed, and the time from development to production has shrunk. Open source compliance has to be automated,” explains Partner Martin von Willebrand. “We are building Double Open, our brand for compliance automation as a service. Embedded Linux can be seen as a kind of ‘Champions League’ for open source compliance. Piloting automated compliance in an environment like that has been very valuable in helping us to develop a service offering accommodating even the most challenging compliance scenarios.”

Vaisala is a global leader in weather, environmental, and industrial measurements headquartered in Vantaa, Finland. Building on over 80 years of experience, Vaisala strives towards its mission of “observations for a better world”.
