BOOK
Books by Nick Shevelyov
Cyber War... and Peace
Cyber War... and Peace
In Cyber War... and Peace, I explore how ancient lessons of resilience and warfare apply to the modern digital battlefield.
It’s part memoir, part leadership guide—an invitation to think differently about how we defend, lead, and grow in an age of constant change.
