About Cybyr.com

An independent resource providing guidance on all aspects of Cybersecurity drawn from decades of experience of software, networking, security and testing. 

An uncompromising approach to a subject that encompasses the entire ecosystem of your working and personal life. It’s why taking a holistic view of a topic that is changing daily is the only viable approach.


To get started, the site features the new book on “Holistic Cybersecurity,” introductory videos, recent blogs and articles on Security in the Network Cloud, Zero Trust and a special video that complements ExO business methodologies. The site draws on the latest in network technologies, architectures, automation that are intertwined with robust cybersecurity. 

This site is also an exploration, a journey. It’s added the concepts of applyiing Zero Trust to delegation, and the developing stories of Network as a Service, board-level cybersecurity and Critical Infrastructure. What began as a glossary of around 50 terms has grown to 280+ in the last year and commentaries on 100+ news items culled from 80,000+ in 2023 alone. My exploration continues to grow with involvement in the Cloud Security Alliance. In 2024 there will be much more to add. Stay tuned.
