Bot management is the practice of detecting automated clients and applying different treatment to good bots, bad bots and humans. It combines signals such as IP reputation, request rate, TLS and header fingerprints, JavaScript or behavioral checks, and challenges like CAPTCHAs.
Why it matters
Large shares of web traffic are automated. Some is useful, like search engine crawlers and your own uptime checks. Some is harmful: credential stuffing, scraping, carding, inventory hoarding and application-layer floods. A blunt IP block catches too much or too little, because attackers rotate through residential and cloud address pools.
For site owners, the main risk is false positives. Overzealous rules can block Googlebot, payment webhooks, partner APIs or your monitoring probes, which then show up as sudden 403 or 429 responses and false downtime alerts.
Example
A pragmatic ruleset might be:
- Allow verified crawlers (confirm by reverse DNS, not the User-Agent string).
- Allow your monitoring IPs and webhook senders.
- Challenge or rate limit login and checkout endpoints.
- Block known abusive networks.
Common mistakes
- Trusting the User-Agent header, which anyone can fake.
- Challenging API endpoints that have no browser to solve the challenge.
- Not allowlisting your own monitoring, then chasing phantom outages.
