Why Kerberus Sentinel3

Web3 moves fast (too fast)

That speed is your biggest edge AND your biggest risk. You're rushing to mint, apeing into trades, chasing the next moonshot. One distraction, one FOMO-fueled click, and it's gone.

  • Most losses happen when you're moving too fast.

  • Too many security warnings? You start ignoring them.

  • Even pros make rookie mistakes when emotions take over.

No effort required

Protection when you need it most

Most Web3 security tools expect you to catch scams (approving alerts, interpreting warnings, making decisions). That doesn't work.

Sentinel3 protects you in the moments you can't protect yourself. No decisions to make. No warnings to interpret. Real-time, enterprise-grade security that stops threats before they reach you.

Scam Detection
Validated by Experience

Kerberus users make the profits.
We help them keep them.

  • Some of the tools rely on blocklists and reports, but others are trying to do more actual detection - which I agree is WAY better. The best is @Kerberus, which automatically detects phishing sites from the moment they launch and a user visits it (which is important for brand new sites). I have never found a scam site in the wild it hasn't detected and they specifically don't rely on blocklists.

  • When it comes to automated anti-scam prevention @Kerberus is the leader. Been battle testing all the competitors for weeks now and the test results speak for themselves. Sentinel3 is #1.

  • @Kerberus challenged me to try bypassing their extension. I must say they have one of the best detection rates I've seen so far.

  • Been using @Kerberus now for two years and I would not touch any transaction without knowing it’s running in the background to keep me safe. This is a one of a kind product that truly revolutionizes the security space we desperately need here in web3. People are sleeping on this but soon will wake up to it.

  • This tool is THE most useful thing, I have used in crypto over the past 3 years. Saved me multiple times already by just ringing the alarm, whenever a contract/mint contained harmful code. If you are active in crypto, you need this - there's no way around
