OUR STORY.

In 2016, Elsine van Os founded Signpost Six in The Hage, The city of Peace and Justice. From the very beginning, our mission has been clear: to empower organisations in proactively identifying and mitigating insider risks, thereby fortifying their security from within.

Over the years, Signpost Six has grown to become Europe’s leading insider risk management firm. Our journey reached a significant milestone in 2023 with the appointment of Dennis Bijker as CEO. Under his leadership, we have expanded our reach and influence, continually setting new standards in the industry.

What sets Signpost Six apart is our unwavering focus on education, training, and strategic advisory services. This year, we proudly launched our own Insider Risk Control Framework, a holistic proprietary tool that we have developed in-house. This framework embodies our dedication to providing innovative and effective solutions that help organisations safeguard their people and data.

At Signpost Six, we aren’t just a service provider; we are a committed partner in the journey to secure your organisation from the inside out. Our story is one of growth, innovation, and an resolute commitment to excellence in insider risk management.

The Hague

We know how!

THE SIGNPOST SIX
APPROACH.

Insiders do not suddenly emerge. People do not switch instantly from non-malicious to malicious acts. People do not suddenly ‘snap’ and start engaging in acts of data theft or violence. The path towards insider acts is evolutionary, with signposts along the way. Therefore, if you want to understand threats, if you want to predict who may conduct an insider act when and where, then you need to be able to understand the signs.

Signpost Six has developed in-house a holistic Insider Risk Assessment Framework, which is unique in the market. By using this approach and leveraging our team’s deep expertise, we can support the public and private sectors internationally with tailored programmes and solutions.
