Beam / learn
Learn cybersecurity, from zero to AI agents
Small lessons, one idea each. Every level builds on the last, and wherever a real CVE or attack shows the idea, we link it.
Level 0
11/11 lessons
Computer foundations
No security yet. How computers, files, networks and the web actually work, so everything later has something to stand on.
Level 1
7/7 lessons
The security mindset
Think like a defender. Threat models, the vocabulary of vulnerabilities, and how to read an advisory.
Level 2
6/6 lessons
Identity, access and secrets
Passwords, sessions, tokens, and the keys that unlock everything.
Level 3
9/9 lessons
Web vulnerabilities
The bug classes behind most real breaches, one per lesson, each tied to a real CVE.
Level 4
7/7 lessons
Systems and memory
What happens below the application: memory bugs, privilege escalation, and sandboxes.
Level 5
7/7 lessons
Networks and defense
Protecting and watching a network: TLS, segmentation, detection and response.
Level 6
5/5 lessons
Software supply chain
You run far more code than you wrote. How it gets compromised.
Level 7
10/10 lessons
AI agent security
Agents read, decide and act. Each of those steps is an attack surface, and each lesson maps to a real incident and a Beam control.
Level 8
6/6 lessons
Agent operations and red-teaming
Run agents safely at scale, test them with authorized exercises, and respond when one goes wrong.
