What We Detect

Comprehensive bot detection covering all major attack vectors and automated traffic patterns.

Headless Browsers

Detect Playwright, Puppeteer, Selenium, and other automation frameworks used for scraping and testing.

Credential Stuffing Bots

Identify automated login attempts using stolen credentials from datacenter IPs and bot networks.

Scraping Bots

Stop content theft and price scraping with datacenter IP detection and behavioral analysis.

Bot Attacks

Protect against DDoS, inventory hoarding, spam, and other coordinated bot campaigns.

Fake Traffic

Filter out fake clicks, impressions, and engagement from bot farms and click fraud operations.

Automated Traffic

Identify any non-human traffic including crawlers, monitors, and automated testing tools.

How It Works

Multi-layered detection combining IP intelligence, network analysis, and behavioral signals.

IP Type Detection

Identify datacenter IPs vs. residential connections. Bots typically operate from cloud providers and hosting networks.

Proxy & VPN Detection

Detect commercial VPNs, proxies, and anonymizers commonly used to hide bot traffic origins.

Tor Exit Node Detection

Identify Tor network exit nodes used for anonymity and frequently abused by malicious actors.

ASN Analysis

Analyze Autonomous System Numbers to identify known bot networks and suspicious hosting providers.

Connection Type Analysis

Examine connection characteristics and patterns that distinguish automated traffic from human users.

Trust Score Explained

Every IP gets a 0-100 risk score. Higher scores indicate bot activity.

0-39

Trusted Human

Residential IP with clean reputation. Strong indicators of legitimate human user activity.

Action: Allow immediately

40-79

Suspicious

Mixed signals. VPN/proxy detected or unusual connection characteristics that warrant additional verification.

Action: Add friction (CAPTCHA)

80-100

Likely Bot

High probability of automated traffic. Datacenter IPs, known bot networks, or suspicious patterns detected.

Action: Block or challenge

Bot Detection FAQ

Common questions about detecting bots and automated traffic.

What is bot detection?

Bot detection is the process of identifying automated, non-human traffic — scrapers, headless browsers, credential-stuffing scripts, and click-fraud bots — before it reaches your application. IPASIS does this server-side with IP intelligence: every request is scored on datacenter/VPN/proxy/Tor detection, ASN reputation, and connection type, returning a 0–100 Trust Score in under 20ms with no JavaScript SDK or CAPTCHA required.

How do I detect bots on my website?

The most reliable way to detect bots is to check the visitor's IP against a real-time intelligence source at signup, login, or checkout. Bots overwhelmingly operate from datacenter IPs, commercial proxies, and flagged high-risk ASNs rather than genuine residential connections. Send the IP to the IPASIS API, read the Trust Score and is_bot verdict, and allow, challenge, or block accordingly. You can try it instantly with our IP lookup tool.

What is a bot detection API?

A bot detection API is a service you call from your backend to determine, in real time, whether a request comes from a human or an automated client. The IPASIS bot detection API is a single REST endpoint that combines IP intelligence and email intelligence into one risk verdict — no per-page tags, no client-side fingerprinting library, and no vendor lock-in to a specific CDN or WAF. See pricing for the free tier.

Is bot detection free to start?

Yes. The IPASIS free tier includes 3,000 requests per month with no credit card required, which is enough to protect a small login or signup flow end-to-end. Paid plans add higher volume and rate limits — see pricing for details.

Can bots bypass IP-based bot detection?

Sophisticated bots rotate through residential proxies to evade datacenter-only blocklists, which is why IPASIS layers ASN behavioral patterns, residential-proxy heuristics, and real-time abuse-signal aggregation on top of basic datacenter detection. This catches rotating proxy traffic while keeping false positives low on legitimate residential users.
