# Cloudflare explained simply: CDN, firewall and free hosting > Cloudflare for a small business: what a CDN is, what the firewall protects you from, and how to host a static site free. Real data: 62% cached. Source: https://cittago.com/blog/cloudflare-cdn-firewall-2026/ Publisher: Cittago — a digital studio in Cluj-Napoca, est. 2011 Published: 2026-07-12 Language: en --- Cloudflare is one of those things "everyone uses" but that few business owners can actually explain. In a nutshell: it's a shield and a shortcut for your website. And most of what a small business — a small or medium business (SMB) — needs from it is free, hosting included when your site is static. **Cloudflare is a shield and a shortcut.** As a *firewall* it stops attacks and harmful bots; as a *CDN* it copies your site onto servers around the world and delivers it from the nearest one, so it loads faster. DDoS protection, SSL and basic CDN are **free**; and with Cloudflare Pages you can **host a static site for free**. Paid plans only matter once you grow. ## What is a CDN, and why does it make a site faster? A CDN (Content Delivery Network) is a network of servers spread across the world, each holding a copy of your site. When someone opens it, the page loads from the server nearest to them — not from yours, which might be on the other side of the planet. Less distance, less waiting. And pages already in cache don't even bother your server. *cittago.com on Cloudflare (free plan) — 62% of traffic served from cache, without touching the server* These are our real numbers: on the **free** plan, over 24 hours **62% of requests** were served by Cloudflare instead of the origin server. Less load, faster pages, a lighter bill. ## Cloudflare's firewall: what does it protect you from? Cloudflare filters traffic before it reaches your site. For free, on the basic plan, you get **DDoS protection** (the attacks that try to knock a site offline by drowning it in requests), **SSL** (the https padlock) and blocking of the cruder bots. The advanced application firewall (custom WAF rules) comes with the paid plans — useful when you handle payments or sensitive data, not essential for a brochure site. ## Free hosting for a static site: really? Yes, with **Cloudflare Pages**. If your site is static — a brochure site, a portfolio, a landing page, a blog — you can host it for free: unlimited sites, unlimited traffic, with a limit only on the number of monthly builds. It's rock-solid and blazing fast because it already lives on Cloudflare's global network. An e-commerce site with a cart and a database needs a real server instead (this is where [LiteSpeed and Redis](https://cittago.com/services/litespeed/) come back in), but for everything that's "content" free hosting is a serious choice, not a compromise. ## Cloudflare and AI: you decide who gets to read your site In 2026 Cloudflare also lets you manage **AI bot access**: you can block the crawlers that train models, or — our choice — let through the ones that read your site to *recommend you* in their answers. If you want to be [cited by AI assistants](https://cittago.com/blog/geo-vs-seo-2026/), those crawlers need to get in. It's a lever that didn't exist before, and it's already in the panel, for free. ## How do I get started? All it takes is the free plan and the right configuration: point the domain at Cloudflare, turn on SSL and caching, set the basic rules. The tricky part isn't switching Cloudflare on — it's configuring it well, because a badly set cache can serve stale pages or break a form. We [configure it by hand](https://cittago.com/services/cloudflare/), domain by domain. ## Frequently asked questions ### Is Cloudflare really free? The basic plan is, and for most small businesses that's enough: global CDN, unlimited traffic, SSL and DDoS protection. You only pay for an advanced firewall, extended analytics or enterprise features, when you genuinely need them. ### Does Cloudflare slow down or break a site? No, when it's configured well: it makes the site faster and safer. Problems come from a badly set cache — which is exactly why configuration matters, not just switching it on. ### Can I host an e-commerce store for free on Cloudflare Pages? No: Pages is meant for static sites. A store with a cart, login and a database needs a real server. Pages is perfect for brochure sites, landing pages, portfolios and blogs. ### Does Cloudflare help me get found by AI? Indirectly, yes: it makes the site fast and stable (which AI rewards) and lets you decide which AI crawlers to allow in. Whether you get cited then depends on your content — we cover that in our guide on SEO and GEO. ## Where Cittago comes in Since 2011 we've put Cloudflare in front of our clients' sites — and our own. We [configure it by hand](https://cittago.com/services/cloudflare/): SSL, caching, firewall rules, AI bot access, and where it makes sense, free hosting on Pages.

Often the part that matters is already free — you just need someone to switch it on the right way. ## Questions and answers **Is Cloudflare really free?** The basic plan is, and for most small businesses that's enough: global CDN, unlimited traffic, SSL and DDoS protection.
