Is there any security safeguards other than contract audits? ICYMI Euler Finance has 6 high tier audits and still drained $170M

I’m no expert in cybersecurity neither do I have a clue on how security due diligence works

I found this web3 security stack post from coinbase. Frankly I don’t know what are most of them for, but is it possible for some of those tools to safeguard smart contracts from exploits?

Maybe something like sec3 able to prevent exploits with their so called WatchTower(?), not sure
