I've noticed that even some small, low-traffic websites redirect me to a Cloudflare network or human-verification check before loading their homepage. Is this something each website owner enables individually, or can it be applied across an entire hosting server? Could my internet provider be causing it? I usually get through without being blocked, but I once saw a warning about malicious bot activity coming from my network, which seems unlikely. I use Chromebooks, although there are also some older Windows computers on my home network.

The website owner chooses whether to put a domain behind Cloudflare; your ISP generally isn’t turning these checks on. Cloudflare is popular because its free and inexpensive plans provide CDN caching, DDoS protection, TLS certificates, and anti-bot tools. Those features are useful even for small sites, especially when they’re self-hosted or don’t have much infrastructure.
Cloudflare can also be used simply as a content delivery network. It caches images and other files near visitors, reducing the load on the origin server and often improving performance. The security checks are an optional part of the service, so a small site may show them because the owner enabled a stricter protection setting rather than because Cloudflare is blanket-blocking an entire server.
Seeing an occasional verification page isn’t automatically evidence that your devices are infected. Cloudflare may be reacting to the reputation of your shared or changing IP address, unusual traffic patterns, browser settings, VPN or proxy use, or a large wave of automated requests affecting that site. However, if you constantly receive challenges across many unrelated sites, check every device on your network—including routers, cameras, NAS systems, TVs, and older computers—for malware or unwanted proxy software.
Small sites can still be hit by huge bot floods or DDoS attacks, and Cloudflare can absorb and filter that traffic before it reaches the actual server. It also lets a site hide its origin IP and only allow Cloudflare’s servers to connect back to the host. That makes it a practical option for a home-hosted site or a modest project, not just for major companies.
A Chromebook by itself is less likely to be the source of traditional Windows malware, but anything connected to the same network could still be responsible. An old, neglected Windows laptop would be worth updating, scanning, or temporarily disconnecting to see whether the behavior changes.
