Three names dominate WordPress security plugin recommendations, and each one is built around a different bet about what site owners actually need most: an active firewall that’s free from day one (Wordfence), a guaranteed cleanup if the worst happens (Sucuri), or a lighter hardening layer bundled with a Patchstack vulnerability feed (Solid Security, formerly iThemes Security). We compared official pricing and free-tier depth across all three.
At a Glance
| Plugin | Free Version | Entry Paid Price | Best For |
|---|---|---|---|
| Wordfence | Active firewall + scanner (30-day-delayed rules) | $149/yr (Premium) | A real firewall at zero cost |
| Sucuri | Monitoring/scanning only, no active firewall | $229/yr (Platform) or $9.99/mo (Firewall) | Guaranteed malware cleanup if you’re hacked |
| Solid Security | Login hardening + file monitoring, no firewall | $99/yr (Pro, 1 site) | Lightweight hardening plus a vulnerability feed |
Short Verdict
If you want one plugin that actively blocks attacks for free, Wordfence wins outright — it’s the only one of the three that ships a working firewall before you pay anything. If what you actually fear is getting hacked and needing it fixed, Sucuri’s paid Website Security Platform is built specifically for that, with unlimited cleanup baked into every tier starting at $229/year. Solid Security Pro sits in between on price ($99/year) but asks you to pair it with another firewall, since its own strength is login hardening and the Patchstack vulnerability database rather than request-level blocking.
Wordfence: The Free Firewall
Wordfence’s free tier (5 million+ active installs, 4.7/5 on WordPress.org) includes a genuine web application firewall, a malware scanner that checks core/theme/plugin files against WordPress.org’s versions, brute-force protection, CAPTCHA, passkeys, and 2FA, plus unlimited multi-site management through Wordfence Central. The catch: free users get firewall rules and malware signatures 30 days after Premium subscribers. Premium removes that delay for $149/year per site and adds a real-time IP blocklist, country blocking, and a remote audit log. Above that, Care ($590/year) and Response ($1,250/year) add a human analyst and incident response rather than just faster software.
Sucuri: Insurance Against the Worst Case
Sucuri’s free plugin (600,000+ installs, 4.2/5) is deliberately limited to monitoring: audit logging, file integrity checks, remote malware scanning, and blocklist monitoring, with no active firewall included. Its paid Website Security Platform starts at $229/year for Basic (30-hour malware response, scans every 12 hours), rising to $339/year for Pro and $549/year for Business (6-hour response, scans every 30 minutes), with every tier including unlimited manual cleanup if you’re hacked. A separate Firewall product is billed monthly ($9.99 Basic, $19.98 Pro) and sits in front of the site as a reverse proxy. The split between Platform and Firewall pricing is the main source of confusion shopping Sucuri.
Solid Security: Hardening Plus a Vulnerability Feed
Solid Security (the plugin formerly known as iThemes Security, rebranded after iThemes became SolidWP) takes a different approach: its free version focuses on brute-force protection, monitoring critical WordPress files for changes, and enforcing strong passwords, without an active firewall of its own. Solid Security Pro costs $99/year for a single site and bundles in Patchstack’s vulnerability database on top of the free feature set. The vendor also sells multi-site license bundles above the single-site price — check solidwp.com directly for current multi-site pricing, since we could only confirm the single-site figure against an official source at the time of writing.
Pros and Cons
- Wordfence pros: free active firewall, largest install base, unlimited free multi-site dashboard. Cons: 30-day delay on free-tier rules; no bundled cleanup guarantee below $590/year.
- Sucuri pros: unlimited malware cleanup on every paid Platform tier; CMS-agnostic, works beyond WordPress. Cons: no firewall at all on the free plugin; pricing split across two separate products.
- Solid Security pros: cheapest paid entry point at $99/year; Patchstack vulnerability feed included. Cons: no active firewall even on Pro, so it needs pairing with another tool for request-level blocking.
Who Should Pick Which
Pick Wordfence if you want the strongest free, active defense and can live with (or pay $149/year to remove) the 30-day rule delay. Pick Sucuri if your real worry is what happens after a breach and you want guaranteed cleanup bundled into the price rather than billed as an emergency add-on. Pick Solid Security if you already have firewall coverage elsewhere (including from your host) and just want cheap, well-regarded login hardening plus a vulnerability feed layered on top.
Bottom Line
None of these three plugins is strictly “the best” — they’re solving different problems. Wordfence is the prevention-first free option, Sucuri is the cleanup-guarantee option, and Solid Security is the budget hardening layer. Most sites are actually best served by picking one firewall-capable option (Wordfence, or a host-level firewall) and deciding separately whether they want a cleanup guarantee (Sucuri) on top of it.
