This article sets correct expectations for what Cloudflare can and cannot protect.
Overview
Cloudflare is an important protection layer, but it is not a replacement for secure hosting, patched software, strong passwords, backups, or correct DNS and firewall configuration.
Recommended Points
- Cloudflare cannot protect traffic that bypasses Cloudflare and reaches the origin directly.
- Cloudflare cannot fix vulnerable website code, outdated plugins, weak passwords, or infected files by itself.
- Cloudflare cannot protect DNS Only services with WAF or HTTP security features.
- Cloudflare cannot make email, FTP, SSH, or RDP safe simply by changing DNS.
- Cloudflare cannot prevent all downtime if the origin server is overloaded, misconfigured, or unavailable.
- Cloudflare cannot safely block aggressive traffic without proper testing and monitoring.
Common Mistakes to Avoid
- Buying Cloudflare but leaving the origin IP public.
- Assuming WAF means the website no longer needs updates.
- Ignoring backups because Cloudflare is enabled.
- Using Cloudflare settings without understanding the service type behind each DNS record.
