Why this page exists

Security history should name the builders, not only the breaches.

Modern teams rely on public-key exchange, strong encryption, resilient routing, coordinated disclosure, DNS repair, bug bounty practice, and security engineering methods created by people who are often invisible outside the field.

Use the timeline to find the origin story behind controls security teams use every day.

Use each profile as a short reference for teaching, onboarding, and recognizing the field properly.

Use the source links to verify names, contributions, and historical context before citing.
