We live in an interconnected world

These are fascinating times. Every day, every minute, every second, more and more people are connected with each other. Offline and online. Physical borders are becoming less and less important. This global interconnectedness introduces new challenges and additional risks. Organisations and institutions are increasingly dealing with diverse partners, competitors and adversaries.

Technology and behaviour

To date, the increasing interconnectedness of our digitalized society has typically been met with technological innovations. Signpost Six recognizes that, besides the importance of technology, human behaviour is at the heart of all these new trends and threats. We can only minimise these risks when we match technology-centred solutions with human-centred solutions.

Our insider risk management mission

Our mission is to help organisations understand and protect their employees from external recruiters and themselves. We help organisations succeed by evaluating and improving their internal countermeasures to become more proactive in managing insider risk. Done right, an insider risk programme not only responds to people at risk quickly and positively, it promotes a supportive culture in the process.

The Signpost Six approach

Signpost Six supports the public and private sector internationally with holistic insider risk programmes. Composed of a team of experienced consultants with deep expertise in psychology, intelligence, insider risk and business, we support you in implementing appropriate countermeasures through our specialised offerings and/or partnerships.

Supporting insider risk journeys

Following the signposts

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 an evolutionary one, 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.
