Cloudflare is a company providing web infrastructure and website security services that protect websites from attacks while improving their performance. Services include content delivery networks (CDN) that cache website content closer to users for faster loading, protection against distributed denial-of-service (DDoS) attacks that try to overwhelm websites with traffic, SSL encryption, and various security tools. Many websites, including government sites, use Cloudflare or similar services to maintain reliable, secure online presence. Understanding that such infrastructure services exist helps explain why websites remain accessible despite cyber threats and why web performance can vary based on technical infrastructure choices.
