About w7sfw
w7sfw is an external firewall that keeps WordPress sites safe — without plugins, servers to manage, or security expertise.
Our mission
WordPress powers a huge part of the web, which also makes it the favourite target of automated attackers. We built w7sfw to make strong, enterprise-grade protection simple enough for anyone to switch on — not just security teams.
How we protect your site
Instead of cleaning up attacks after they reach WordPress, w7sfw stops them at the edge. We block all incoming traffic first, then let only verified-safe requests through using our System Rules and an Active Whitelist, and add two-factor authentication on your login. Threats are filtered before they ever touch your server.
Built on global infrastructure
w7sfw runs on a worldwide server network — across Asia, Europe, and the US — backed by System443. Wherever your visitors are, protection stays fast and stable.
Who it's for
From personal blogs to high-traffic business sites, w7sfw scales with you. Start free and upgrade to Pro, Business, or a fully custom setup as your needs grow.
