About Nexus-7
Your partner in cybersecurity awareness and risk assessment
Joint Venture
Nexus-7 is a joint venture between Vuurpijl Beheer BV and Semper Prorsum BV, combining technical expertise with scientific methodology.
Why Nexus-7?
The Problem
95% of all cybersecurity incidents are caused by human error. Companies invest millions in firewalls, antivirus, and security tools, but overlook their biggest risk: their own employees.
Traditional security awareness training offers generic checklists and boring e-learning modules. They don't truly measure whether employees are vulnerable to phishing, social engineering, or other attacks. You only discover your weakest links after a breach.
Our Solution
Nexus-7 uses Q-methodology - a scientifically validated research method - to measure employees' actual behavior and attitudes toward cybersecurity. Not what they say they do, but how they actually think.
Our assessments identify specific vulnerabilities per employee and per team. This way, you know exactly where to focus your training and attention. From reactive to proactive: prevent incidents before they happen.
What makes us different?

Q-methodology from behavioral science - not guesswork, but proven insights
