Global – October 24, 2026 -- Cloudflare's Learning Center covers 16 topic areas, from DDoS attacks and DNS to AI, SASE and domain registration, according to the resource index.
Security guides cover DDoS, bots, email and web applications
The DDoS guide describes a network of computers working in tandem to overflow an access point and block legitimate users from a service. The bots guide separates helpful automated applications from malicious ones that can harm sites and applications.
The web application security guide calls for a holistic approach to mitigating attacks. The email security guide covers preventing email-based cyber attacks, protecting accounts from takeover and securing message contents. The SSL guide describes the protocol, known today as TLS, as an encryption protocol running on top of HTTP to protect communication between servers and clients.
Infrastructure guides explain CDNs, DNS, cloud, SASE and the network layer
The CDN guide covers distributed servers that work together to deliver Internet content, improving loading speed and reliability. The DNS guide describes the system as the worldwide network connecting users to web content via domain names. The cloud guide defines the cloud as servers accessed over the Internet, plus the software and databases running on them, located in data centers worldwide.
The SASE guide describes an IT model combining software-defined wide area networking with core security services delivered on the cloud edge. The network layer guide covers how connections occur by sending data packets between different networks.
Performance, serverless, streaming and AI guides target developers
The performance guide states that web applications that load quickly see higher conversion rates and better SEO performance. The serverless guide covers writing and deploying code without managing underlying infrastructure.
The video streaming guide spans file formats to live encoding. The AI guide covers LLMs, embeddings and vector databases. Remaining guides address data privacy and domain registration.
