- Analytics: Cloudflare provides detailed analytics on website performance, security threats, and visitor demographics, enabling users to optimize their sites based on actionable insights.
- Rate Limiting: This feature helps protect against abuse by limiting the number of requests a user can make in a given timeframe, safeguarding against brute-force attacks.
