w7sfw vs Wordfence vs Sucuri: WordPress Firewall Comparison
How w7sfw compares to the two most popular WordPress security tools — where each runs, what it costs, and which one fits your site.
Short answer: w7sfw and Sucuri both block attacks at the edge before they reach WordPress and both include a CDN, while Wordfence runs as a plugin inside WordPress. w7sfw is the easiest edge firewall to start with — it has a free plan, needs no WordPress plugin, and won't slow your site.

The details
w7sfw vs Wordfence
Wordfence is a popular plugin that runs a web application firewall and malware scanner inside WordPress. Because it runs as PHP inside your site, requests reach WordPress before they're inspected, and it can add server load. w7sfw blocks traffic at the edge before it reaches WordPress, with no plugin to install and no risk of conflicts, and serves your static files from a built-in CDN. Wordfence's strength is its deep file-level malware scanner; w7sfw's strength is stopping attacks before they ever load.
w7sfw vs Sucuri
w7sfw and Sucuri are both edge solutions: each routes your traffic through its own global network (so both involve a one-time DNS change), includes a CDN, and blocks attacks before they reach WordPress. The differences: w7sfw has a free plan and starts at $20/month, sets up through a Google-approved browser extension with no WordPress plugin, and adds firewall-layer 2FA. Sucuri is paid-only, needs a helper plugin, and adds hands-on managed malware cleanup.
Which should you choose?
Choose w7sfw if you want edge protection — with a built-in CDN — that's free to start, simple to set up, and won't slow your site or conflict with plugins. Choose Wordfence if you specifically need an in-WordPress malware scanner. Choose Sucuri if you want managed, hands-on malware cleanup and don't mind paid-only setup.
Comparison FAQ
Is w7sfw a good Wordfence alternative?
Yes. If you want firewall protection that runs outside WordPress instead of as a plugin, w7sfw blocks attacks before they reach your site, avoids plugin conflicts and 403 errors, and won't slow your site down. It also serves your static files from a CDN. Both have a free tier, but w7sfw filters traffic at the edge rather than inside WordPress.
Is w7sfw cheaper than Sucuri?
Yes. w7sfw has a free plan and paid plans from $20/month, while Sucuri is paid-only starting around $199/year. Both are edge firewalls that include a CDN and route traffic before it reaches your site, but w7sfw is far cheaper to start.
Does w7sfw scan for malware like Wordfence and Sucuri?
w7sfw focuses on blocking malicious traffic at the edge before it can reach WordPress, rather than scanning files after an infection. For deep file-level scanning you can pair it with a scanner; for prevention, edge filtering stops most attacks far earlier.
Do I need to change my DNS to use w7sfw?
Yes. Like other edge firewalls — including Sucuri — w7sfw routes your traffic through its global network, which needs a one-time DNS change. Setup is guided and takes minutes, with no WordPress plugin to install and no code changes, and your static files are then served from the nearest edge server.
