PeckShield's real-time exploit alerts on X/Twitter are genuinely useful — if you follow blockchain security, you've probably seen their posts. Their audit engagements ($10,000–$30,000+, 2–5 weeks) are solid. But their brand is built on monitoring after exploits happen — not preventing them before launch.

There's a real distinction here that matters. PeckShield's strength is detecting exploits as they happen — their monitoring infrastructure watches on-chain activity and flags anomalies in real time. That's valuable for post-launch protocols with significant TVL that need early warning.
But the Cream Finance exploit they alerted about in October 2021? That $130M loss was from a flash loan price manipulation vulnerability that existed in the contract before deployment. Monitoring told the world it was happening. Pre-deployment analysis would have stopped it from happening.
This isn't a criticism of PeckShield — it's a clarification of what you're buying. If you want post-launch monitoring coverage, PeckShield is one of the best. If you want to prevent vulnerabilities from being deployed in the first place, that's a different tool.
The vulnerability classes that cause real losses — not edge cases, but the patterns that show up in post-mortems repeatedly:
initialize() functions callable by anyone, missing onlyOwner on administrative functionsdelegatecall — proxy upgrade logic exposed to arbitrary callersAI-powered analysis catches all of these in under 60 seconds, on every commit. PeckShield's monitoring tells you after one of them gets exploited. Use both — they're complementary, not competitive.
This stack gives you prevention (AI pre-deploy) and rapid response (PeckShield post-launch) without the redundancy of paying two firms to do the same thing.
