BD Security Firewall vs Sucuri: in-process plugin vs cloud WAF

Sucuri is a cloud-based security service: their WAF sits in front of your site as a reverse proxy, and they sell incident response. BD Security Firewall is a plain WordPress plugin that runs in PHP on your own server. These are different products solving overlapping problems — pricing them like-for-like is misleading, so this page tries to be fair about that.

Pick BD Security Firewall if…

Pick BD if you want plugin-level protection without changing DNS, without trusting a third party with traffic, and without a $200+ floor.

Pick Sucuri if…

Pick Sucuri if you want a cloud WAF that blocks attacks before they hit your server, post-hack incident response included, or DDoS mitigation at the network edge.

Switching from Sucuri?

Expect to lose edge-level filtering and CDN — gain in-process WAF, 2FA, FIM, headers, and geo-blocking on your own infrastructure for less money.

When to pick which

Pick Sucuri if you want a cloud WAF that scrubs traffic before it reaches your origin server. That's a real architectural advantage — bots, exploit scanners, and Layer 7 DDoS attempts get filtered at the edge, your PHP-FPM workers never see them, and your origin can sit behind their IP allowlist so direct attacks become impossible. The included incident response (unlimited malware cleanup requests at any paid tier) is also genuinely valuable: if your site gets hacked, you open a ticket and their team cleans it. That alone justifies the price for some operators.

Pick BD Security Firewall if you don't want to change DNS, don't want a third party in your traffic path, and don't need cloud-level DDoS mitigation. BD runs in PHP, so it can only filter requests after they've reached your server — but for the typical small-to-medium WordPress site behind a reasonable host, that's the threat model that actually applies. The included 2FA (TOTP + email), FIM, headers, geo-blocking, and login protection cover the same ground Sucuri's plugin does, minus the cloud edge.

These products aren't substitutable for everyone. If you're running a high-traffic site that's been DDoSed, Sucuri (or Cloudflare) is the right answer regardless of cost. If you're running a brochure site, an agency client portfolio, or a shop, BD does the job for a quarter of the price.

Migrate from Sucuri to BD Security Firewall

1. Install BD Security Firewall and activate the license while Sucuri is still in front of your site.
2. Configure BD's WAF, 2FA, FIM, and security headers — whitelist your own IP.
3. Test that BD's rules don't conflict with Sucuri's edge rules (look for double-blocks).
4. In Sucuri's dashboard, change DNS back to your origin server (revert the proxy).
5. Wait for DNS to propagate (up to 24h) and confirm traffic is hitting your server directly.
6. Cancel Sucuri (or downgrade to free monitoring if you want the remote scanner).
7. Install BD Malware Cleaner if you want ongoing file scanning to replace Sucuri's remote scan.

FAQ

Doesn't a cloud WAF beat a plugin WAF?

For DDoS and bot-traffic offloading, yes u2014 that's exactly Sucuri's pitch. For application-layer rules (SQLi, XSS, login abuse), a plugin WAF can be just as effective because it has full request context. Different layers, different strengths.

Will I lose CDN if I switch?

Yes u2014 Sucuri's CDN comes with the proxy. If you need a CDN, run Cloudflare's free tier alongside BD; you'll get most of the edge benefit without paying $200/yr.

What about malware cleanup if my site gets hacked?

Sucuri includes unlimited cleanup requests at any paid tier u2014 that's their differentiator. BD doesn't. If you want that safety net, factor it in or budget for emergency cleanup separately.

Is BD's WAF as good as Sucuri's?

For application-layer attacks, comparable. For volumetric attacks (DDoS), no u2014 that requires network-edge filtering that no plugin can provide.

Can I run both?

Yes, and many operators do u2014 Sucuri at the edge plus a server-side plugin gives layered defense. Just disable BD's WAF if Sucuri's is already filtering, to avoid double-processing.

# BD Security Firewall vs Sucuri

Sucuri is, technically, not really a WordPress plugin company. They sell a cloud security service: a reverse-proxy WAF, an Anycast CDN, malware monitoring, and incident response. The WordPress plugin is a thin client that ties into the platform. BD Security Firewall is the opposite — a self-contained PHP plugin that runs entirely on your server with no cloud component.

Comparing them by feature checklist is misleading because they operate at different layers. Sucuri’s WAF sees a request before it reaches your origin; it can null-route a DDoS, allowlist by ASN, and serve a challenge page on volumetric attacks. BD’s WAF sees a request after Apache/nginx has handed it to PHP — by definition, every request has already cost you a worker process. That’s a real architectural disadvantage on high-traffic sites and a non-issue on low-traffic ones.

What Sucuri does that BD can’t: edge DDoS mitigation, traffic offload via CDN, post-hack incident response (unlimited cleanup requests are included in any paid tier — that’s the part of the bill that’s genuinely worth $200/yr if you’ve ever been hacked), and a network-effect malware database from monitoring tens of thousands of sites. What BD does that Sucuri’s plugin doesn’t: built-in 2FA with email OTP, a security headers panel, integrated activity logging, no DNS changes, no third-party in your traffic path.

The pricing gap looks dramatic — $49 vs $200 at the entry tier — but it’s not a fair comparison. Sucuri’s $200 buys you a CDN, a cloud WAF, and a cleanup team. BD’s $49 buys you a plugin. If you need what Sucuri sells, BD is not a substitute.

Where BD does substitute well: agency portfolios where the threat model is “automated bot traffic and credential stuffing, not targeted DDoS,” shops behind decent hosts that already have basic L4 protection, and operators who don’t want a third party in their request path for compliance, performance, or principle reasons. The single-vendor bundle (BD Backup, BD Malware Cleaner, BD Uptime Monitor under one license dashboard) is also a real workflow advantage if you manage many sites.

Honest summary: Sucuri is a better product for high-risk and high-traffic sites, and we’re not going to claim otherwise. BD is a better fit for normal sites at normal traffic with normal threat exposure — which is most sites.
