Episode notes
Invest Early To Save On Security
- Start security from day one; it is cheaper and faster than retrofitting before launch.
- Continuous tooling reduces audit cycles, remediation time, and total security spend.
Bunny Protocol's Costly Post-Hack Reality
- Bunny Protocol shared that manual audits to relaunch after a hack would cost six to seven figures, so they could not relaunch.
- This shows how manual-audit-heavy approaches can bankrupt smaller teams after incidents.
Practical Security Budgeting
- Budget for security tooling, audits, and bug bounties; startups can often start with $25–100K/year.
- Scale spend as your product and TVL grow and add more audit cycles and bounties accordingly.
