Netbait is a free IP scorer and IP reputation API. IP reputation is a score that measures how malicious an address is. Scanners, botnets, credential harvesters and automated exploit kits leave traces across the internet as they operate. We collect those traces, correlate them across the full IPv4 space and compute a score in real time. A single number, from clean to confirmed threat, before you even reply to them.
Scanners map your infrastructure before you know they are there. Botnets flood services with traffic until they collapse. Proxies rotate through thousands of addresses to game ad networks and harvest revenue that was never theirs. Scripts create duplicate accounts at scale, bypassing every limit you put in place.
Behind them are operators running from jurisdictions where no law enforcement will ever reach them. Offshore hosts, bulletproof infrastructure, untouchable by design. They operate in the open because nothing stops them.
We know all of them. Every address that has ever participated in an attack, a scan, a DDoS, an ad fraud ring or an account farm has been catalogued, scored and made queryable in milliseconds.
They have all been identified.
We did not build Netbait in a lab. We deployed it. Across several hundred routers in production, handling real traffic, under real conditions. On every one of them, 80% of inbound connections were blocked before reaching a single service behind the network.
The effect was immediate. Those routers stopped appearing in scanner results. The infrastructure behind them went dark to hostile actors. No alerts, no incidents, no noise to manage. Just silence.
They have never been more at peace.
Netbait runs on Netbait. Every request hitting our infrastructure passes through the same filtering we offer you. Hostile traffic never reaches us, which means we never pay to handle it, store it, or absorb it.
When 80% of inbound noise is eliminated at the edge, infrastructure costs collapse. There is nothing left to bill for. The core API is free, and it will stay that way.
Internet noise is not your problem to solve. Scanners, botnets and hostile traffic exist whether you deal with them or not. Let us filter them out entirely, so you can build, ship and grow without looking over your shoulder.
One API call per connection. That is all it takes.
