Our Mission

We make cybersecurity a seamless part of everyday work.

Pistachio was founded in Oslo in 2019 to make cybersecurity accessible to every business. Today we support hundreds of organizations worldwide.

By integrating with Microsoft SSO, any Pistachio product can be set up in under ten minutes. Then it runs quietly in the background, no maintenance required.

Pistachio Principles

Our work is guided by three core principles

(01)

Realistic

We design for how organizations actually work, not how security tools think they should. By understanding real workflows, our products make security effective, approachable, and seamless.

(02)

Seamless

Strong security shouldn’t require constant effort. Our products set up quickly, run quietly in the background, and need almost no manual attention so teams can stay protected without extra resources.

(03)

Adaptable

Organizations are always changing. Tools are updated, workflows shift, and environments grow more complex. At the same time, threats evolve to exploit those changes. Our products adapt alongside both, helping your organization stay secure in a world that never stands still.
