About us

Why we exist

Insider risk has a long history. What has changed is the challenge of managing it. Modern organisations collect, process and rely on digitised business information on a scale unheard of before while criminals continually discover new ways to monetize it. In the middle stand employees. These employees often have access to intellectual property and trade secrets representing an organisation’s most valuable assets and whose loss can pose an existential threat.

As humans, these employees also have vulnerabilities. Attackers understand this and are increasingly leveraging insiders now that organisations have made attacking externally harder. Our mission is to help organisations protect their employees before the attackers reach them and before the demands of modern society derail them psychologically. But it’s more than that. It’s to help organisations succeed through introspection and improvement of their internal processes to become a proactive and supportive culture. And we know-how.
