Hi, Ragnar here.

I do _

Based in the UK, I work with my global network of colleagues and contacts to help protect data from threats every day.

Over the last two decades I’ve worked in both the private and public sectors, for small, medium and enterprise organisations. My experience spans across many fields including GRC, Security Operations and more recently Security Strategy.

My goal is to make navigating the difficult world of cyber security easier for everyone. The problems we have need simple, effective and understandable solutions we can all use!

Training for a Security Operations team

Some say the only constant in life is change, and that’s very true in the world of information security. In this post I talk about my approach to training for security operations teams.

Returning to the blogosphere

After 11 years of this site effectively being shelved and gathering virtual dust, I’ve finally returned to it and am producing information security related content.
