Inside the Mind of a Web3 CISO: Lessons from Leading Security at a Top DeFi Protocol

What Security Execs Look for in Talent, Culture, and Strategy


🎙 Introduction

We sat down with the (anonymized) CISO of a top 20 DeFi protocol managing over $1B in TVL. With 15+ years in cybersecurity and the last 3 in Web3, he shares how the best teams build security into their culture, hire smarter, and avoid the most common mistakes.


🧭 Q1: What’s the CISO’s Real Mission?

“Protect funds, protect uptime, protect users. That’s it. But in Web3, that touches everything: smart contracts, wallets, Discord servers, even governance.”

He described his role as both technical and strategic—often mediating between engineers, DAOs, and external auditors.


🔍 Q2: What Kind of Talent Do You Prioritize?

“Curious problem solvers. I’ll take someone who can model an attack and explain it clearly over a resume full of certs.”

Roles he highlighted as most critical:

  • Smart Contract Auditors

  • DevSecOps Engineers

  • Security PMs

  • On-Chain Monitoring Leads

  • Bug Bounty Managers


📦 Q3: When Should Protocols Start Hiring Security Talent?

“Before your audit. You want a security-aware codebase and test suite before the report. Too many teams go in blind.”

He recommends a part-time or fractional hire as early as testnet phase.


⚠️ Q4: Biggest Mistake He Sees Founders Make?

“They treat audits like insurance. One audit = safe. Not true. Security is iterative. It’s process, not a moment.”

He stressed the importance of treating audit reports as living documents tied to internal checklists.


💬 Q5: Final Advice for Founders Hiring Security?

  • Ask for GitHub activity or audit reports—not just a CV

  • Hire for alignment with your stack (Solidity, Rust, etc.)

  • Prioritize strong communicators who can document and teach others

  • Build security champions inside your eng team—not separate from it
