Stop the bots that are actually targeting you.
Humans + good bots pass. Malicious bots filter out.
Bot traffic is now the majority. Most of it isn't yours.
CrownWall identifies and acts on automated clients across multiple categories — without breaking the search engines, monitors, and integrations you actually want.
Multi-category detection
Know the difference between a threat and a customer.
Credential stuffing
Automated login attempts using leaked credentials. The most common attack against authenticated APIs.
Vulnerability scanners
Probes for known CVEs, exposed admin panels, default credentials, and misconfigurations.
Scrapers & crawlers
Content theft, price scraping, inventory monitoring, and data harvesting.
AI & LLM scrapers
The fast-growing category harvesting content to train models, often ignoring robots.txt.
DDoS tooling
Application-layer denial-of-service tools that flood specific endpoints with low-volume, hard-to-detect traffic.
Verified good bots
Googlebot, Bingbot, monitoring tools, partner APIs. Identified and allowed — never blocked by mistake.
Not every bot needs the same answer.
Block
For clearly malicious categories like credential stuffing.
Challenge
A JavaScript or browser-fingerprint challenge real browsers pass invisibly.
CAPTCHA
Interactive challenge for borderline cases.
Allow
For legitimate categories you want through.
Log-only
Observe without acting while you refine your policy.
Why this matters for SaaS.
If your application has paying customers logging in through authenticated API calls, credential stuffing isn’t hypothetical. It’s happening now, and standard firewall rules won’t catch it.
