Security and CDN

Small websites are attacked constantly, mostly by automated bots that look for weak passwords, outdated plugins and known security holes. Security services and content delivery networks sit in front of your site or inside it to block that traffic and keep pages loading for real visitors.

A CDN, or content delivery network, keeps copies of your pages and images on servers around the world and serves them from the one closest to each visitor. Cloudflare and Bunny.net are the most common choices for small sites. Cloudflare also adds a firewall, DNS and bot filtering, and its free plan covers many small sites. Sucuri pairs a firewall and CDN with malware cleanup if a site has already been hacked.

For WordPress, security plugins work from inside the site. Wordfence adds a firewall and malware scanner. Jetpack covers backups, scanning and an image CDN. Patchstack watches your plugins and themes for known vulnerabilities and patches them until updates arrive. MalCare runs its scans on its own servers to keep the load off your hosting plan.

AI and machine learning appear mostly in bot detection and malware scanning, where providers use patterns across many sites to spot attacks. You will not usually configure that directly. What you do control is the basics: update WordPress, plugins and themes, remove ones you do not use, use strong passwords and two-factor sign-in, and keep backups off the server.

Avoid stacking several security plugins, which can conflict and slow a site. Ask your host what it already runs at the server level, then fill the gaps.

Keep a short list of what protects your site and where each piece runs: the host's server firewall, Cloudflare or another CDN in front, one security plugin inside WordPress, and backups stored elsewhere. When something goes wrong, that list tells you where to look first and which support team to ask.

Watch your login page too. Limit login attempts, use a strong unique password for every admin account, and remove admin accounts for people who no longer work on the site.

If you sell online or take personal details through forms, check what your payment provider and form tools already handle for you. Card data usually stays with the payment processor, which reduces what your own site has to protect, but contact forms and customer accounts still need care.

Questions about security and cdn

Does a small site need a firewall?

It helps. Most attacks on small sites are automated, and a firewall blocks a lot of that traffic. Cloudflare's free plan or a WordPress security plugin are common starting points.

What is a CDN and do I need one?

A CDN serves cached copies of your pages and images from servers near each visitor. It helps sites with visitors in many places and adds protection against traffic floods. Many small sites use a free one.

Can I use more than one security plugin?

It is better not to. Two firewalls or scanners can clash and slow the site. Check what your host runs at the server level and add one plugin for what is missing.

What should I do if my site is hacked?

Take the site offline or put it in maintenance mode, change all passwords, restore a clean backup if you have one, and update everything. Services such as Sucuri or MalCare also clean infected sites.
