OpenCart DDoS and Bot Protection

Description

Online stores are regular targets for automated attacks: scrapers collect prices, parsers overload the server, competitors order DDoS. For OpenCart this is particularly painful — every unauthorised catalogue request generates SQL queries to the database.

We configure multi-layer protection for OpenCart and ocStore: from Cloudflare at DNS level to Nginx rules and fail2ban at server level. The solution is matched to the threat type and scale of your store.

Protection Layers

• Cloudflare — traffic filtering at CDN level before reaching the server
• Nginx rate limiting — request frequency limit per IP address
• fail2ban — automatic IP blocking for suspicious behaviour
• Parser blocking by User-Agent and behavioural patterns
• CAPTCHA or JavaScript challenge for suspicious sessions
• Admin panel login protection against brute-force

Configuration Approach

Overly aggressive protection blocks real buyers. We find the balance: analyse your server access logs, determine the legitimate traffic profile, and configure rules so protection does not affect conversion.
