DDoS protection for a small site: what actually helps and what is overkill
In one line: You probably do not need an enterprise scrubbing centre. Here is what a distributed flood actually is, what realistically protects a small site, and what to ignore.
"DDoS" sounds like something that only happens to banks and governments, but small sites get hit too — sometimes deliberately, often as collateral. The good news is that for almost every small site the defence is not an expensive appliance; it is mostly a matter of being on the right infrastructure and not panicking. Understanding what the attack is tells you what actually helps.
What a DDoS attack actually is
A distributed denial-of-service attack floods your site with more requests than it can handle, from many machines at once, so real visitors cannot get through. It is about volume, not intrusion — the attacker is not stealing data, they are trying to make the site unavailable. That distinction matters: the defences are about absorbing or filtering traffic, not about locks and keys.
What realistically protects a small site
The single most effective step is putting the site behind a CDN or reverse proxy, which absorbs and filters a huge amount of junk before it reaches your server — the same CDN that speeds up your site in what a CDN does also hides your origin and soaks up floods. A web application firewall (what a WAF is) adds request filtering on top. And being on hosted or cloud infrastructure that can scale helps, because a fixed single server is the easiest target. For most small sites, "behind a reputable CDN with its DDoS mitigation on" is 90% of the answer.
What is overkill, and what to do during an attack
Dedicated scrubbing services and enterprise contracts are for sites that are targeted repeatedly at scale — not for a blog or a small shop. If you are hit, the practical moves are boring: let the CDN absorb it, do not keep restarting your server (it will just be flooded again), and contact your host or provider, who often have mitigation you can enable. And keep the basics solid — security headers, patches — because the goal of most small attackers is disruption, and a site that is resilient and uninteresting is left alone.
