Real-time bot detection
for any website or API.
ZeroBot scores every visitor the moment they arrive — combining device fingerprinting, IP reputation, ASN and datacenter detection, and behavior. Real users pass instantly; bots get blocked.
Bot detection in three layers.
The most accurate detection never relies on one signal. ZeroBot stacks server-side, client-side, and challenge layers so bots are caught while real users are never stopped.
1 · IP & network
Instant server-side check: IP reputation, ASN, datacenter and proxy detection — a verdict before the page even loads.
2 · Fingerprint & behavior
Client-side device fingerprinting catches headless browsers, automation, and spoofed clients that pass an IP check.
3 · Challenge
Borderline visitors get a soft captcha — a real person clears it in one click, a bot is stopped cold.
Every kind of automated traffic.
Headless & automation
Puppeteer, Selenium, Playwright, and headless Chrome — detected by fingerprint, not just user-agent.
Credential stuffing
Brute-force and account-takeover bots hammering your login, stopped before they reach it.
Scrapers & crawlers
Content and price scrapers copying your site in bulk — blocked at the source IP.
Datacenter & proxy bots
Traffic from AWS, hosting providers, VPNs and residential proxies, flagged by ASN intelligence.
Fake signups & spam
Bogus account creation and form spam that pollutes your data and inbox.
Never blocks real users
Tuned so genuine residential and mobile visitors always pass. Zero false positives is the goal.
