CAWACHLABS
Zero-trust engineering, taught by a practitioner.
Advanced courses for engineers who design, secure, and operate real networks.
In production: Advanced Zero Trust Architectures with OpenZiti 2.0The name
Cawach is kavach — the shield
Cawach is a phonetic respelling of kavach (कवच) — the shield. The promise is protective engineering: zero-trust architecture taught the way it runs in production, trade-offs and failure modes included.
The craft
Built like the systems it teaches
Every course is engineered, not assembled. Decks, diagrams, labs, and motion render from code against a versioned design system — a shipped course rebuilds pixel-identical years later.
Written for peers
You're addressed as a senior engineer. Exact flags, exact versions, sources cited — and nothing over-explained.
Labs that end clean
Every lab closes with cleanup and troubleshooting sections. Real environments deserve both.
Now in production
Advanced Zero Trust Architectures with OpenZiti 2.0
Thirteen modules on designing and operating zero-trust architectures with OpenZiti 2.0 — HA controller clusters on RAFT, edge routers, tunnelers, and the identity plane — with hands-on labs in real environments.
A follow-on to the instructor's OpenZiti 1.0 course on Udemy.
