I was sceptical about how much difference a CDN would make for a small site. It made a significant difference. Setup was literally one DNS change.
CONTENT DELIVERY NETWORK (CDN)
Faster pages. Happier visitors.
Better rankings.
44+ global data centres serve your content from the closest location
— cutting load times by up to 50%
Faster pages for every visitor, wherever they are
SiteLock’s global Anycast network delivers your content from the edge location nearest each visitor — proven to improve page load times by 50% on average. Images, scripts, and files are automatically compressed and minified before delivery, so your site feels fast without you changing a line of code.
Smart caching that works for every type of site
Static content, dynamic pages, product listings, blog posts — the CDN caches what should be cached and keeps real-time areas like carts and checkouts always fresh from your server. No manual tiers to configure. Smart caching rules adapt to your site automatically, and you can clear or adjust in a couple of clicks when content changes.
AI-powered protection built into every delivery
Every request passes through machine learning-powered threat detection before it reaches your site. Bots, DDoS floods, and automated attacks get challenged or blocked in real time — while genuine customers pass straight through, even during traffic spikes. Security that gets smarter every day, with no manual configuration required.

Content Delivery Network (CDN) in-depth
| Global Delivery & Speed | |
|---|---|
| Make pages feel fast for every visitor — not just nearby ones | Serves content from edge locations in 44+ data centres worldwide, so each visitor connects to a nearby server and sees your pages load quickly wherever they are |
| Stay responsive during traffic spikes | Spreads incoming requests across the CDN’s global network so campaign surges, viral posts, or seasonal peaks do not overwhelm your origin server or slow your site down. |
| Do more with the hosting you already have | Offloads a large share of requests and data transfer to the edge, cutting bandwidth at your origin by a significant margin and freeing server capacity without new hardware |
| Keep pages fast even as your site grows | Caches both fixed assets and frequently accessed dynamic content so adding pages, products, or rich media does not automatically mean slower load times |
| Smart caching & content freshness | |
|---|---|
| Keep dynamic pages both fast and current | Refreshes cached versions of important dynamic pages in the background, so visitors get quick responses without seeing stale content. |
| Supercharge your highest‑traffic pages | Lets you set rules for high‑traffic pages such as product listings, landing pages, or articles—so they are served from the edge most of the time for maximum speed |
| Clear out stale content the moment you update it | Allows you to clear cached versions instantly—across the whole site or for specific URLs—so visitors see updated content and promotions as soon as you push them live. |
| Choose a caching mode that matches your site | Supports setups ranging from mostly static sites to dynamic, CMS‑ or e‑commerce‑driven sites, so you can push caching hard where it is safe and keep it conservative where freshness matters most. |
| Content optimisation | |
|---|---|
| Shrink file sizes without touching your code | Automatically tidies up JavaScript, CSS, HTML, and other text‑based assets at the edge—removing unnecessary characters and compressing files so they travel faster, without you changing anything in your site. |
| Speed up image‑heavy pages | Optimises common image formats before delivery, reducing file sizes while preserving quality so galleries, product photos, and blog images still load quickly. |
| Reduce connection overhead for repeat visitors | Reuses and optimises network connections so new requests do not pay a full “handshake” cost each time, helping pages begin loading faster for repeat visitors |
| SSL & Secure Delivery | |
|---|---|
| Deliver every page over HTTPS without performance cost | Handles endtoend SSL for all requests and supports major certificate types—including multidomain and EV—so visitors get a fully encrypted experience with no extra tuning on your side. |
| Work with the certificates you already have | Supports custom certificate upload and common formats, so you can keep your existing SSL setup while taking advantage of edge delivery. |
| Performance visibility & dashboard | |
|---|---|
| See how much work the CDN is doing for you | Performance views break down how many requests and how much data come from cache versus your origin, giving you a clear picture of the load the CDN is absorbing |
| Understand where performance matters most | Country‑ and browser‑level traffic insights show where your visitors are and how they access your site, helping you see which regions and clients benefit most from edge delivery. |
| Manage performance and security in one place | CDN settings live alongside your firewall, SSL, and related controls in a single dashboard, so you tune speed and protection together instead of juggling multiple tools. |
Security + Speed In One Layer
CDN and WAF — built to work together
One DNS change turns on both. Your content gets delivered fast from a global network of edge locations — and every request is filtered for threats before it reaches your site. No separate tools. No separate setup. Just a faster, safer site from day one.
SiteLock's threat detection watches traffic in real time. When something looks suspicious — a bot probing for weaknesses, a DDoS flood of fake requests — it automatically applies a smart verification challenge. Real customers pass straight through, even during busy periods, with no manual configuration required.
And if you ever have a question, you reach a real person — not a ticket, not a queue.
FAQ
Does the CDN help with SEO?
Yes, directly. Google uses page load speed as a confirmed ranking factor. Faster sites rank better, stay ranked longer, and have lower bounce rates — which is itself a quality signal to search engines. A site loading 50% faster, with compressed assets and shorter TTFB, is in a meaningfully stronger SEO position than the same site without a CDN.
How does setup work?
One DNS change routes your traffic through SiteLock’s network. The CDN and WAF both activate at the same time. No hardware, no software installation, no server access required. The dashboard confirms CDN status once routing is live. From sign-up to active delivery: approximately five minutes.
Will the CDN affect how my site looks or behaves?
No. The CDN operates at the network layer, not inside your site. It caches and delivers your existing content faster — it doesn’t modify layouts, templates, or functionality. Minification removes whitespace from code files without changing how they work. If you ever need to verify the latest version is being served, you can purge the cache instantly from the dashboard.
Is this different from the CDN my hosting provider offers?
Likely yes, in two important ways. First, SiteLock’s CDN activates alongside the WAF through the same DNS change — you get threat filtering and content delivery in one layer, not separately managed products. Second, SiteLock’s CDN caches both static and dynamic content, where many basic hosting CDNs only cache static assets. If your site has personalised content, account pages, or a WooCommerce or Magento store, that distinction matters.
Does it work with dynamic content and e-commerce sites?
Yes. SiteLock’s CDN supports both static and dynamic content caching. For e-commerce sites running WooCommerce, Magento, or similar platforms, you can set rules to always cache product pages and images while never caching cart, checkout, or account pages — ensuring visitors get fast loads for browsing and accurate real-time data for transactions.
