WordPress security plugins harden logins, filter hostile traffic, scan for malware and warn about vulnerable extensions on sites that run the platform.
This guide orders them by the independence of the maker, then by what the first ninety days demand, the true yearly bill across several sites, how cleanly you can leave, and whether the tool blocks, reports or repairs.
Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.
In short
What wordpress security plugins software does
A WordPress security plugin protects a site from attacks by limiting logins, filtering bad traffic, scanning files for malware and flagging vulnerable plugins, themes and core versions.
Each wordpress security plugins tool was put through the same five questions, in sequence: how hard is setup, what does it really cost, how does data come back out, can you leave, and who is it for. A challenger rule applies on top. Places 1 to 3 are kept for lesser-known vendors when the category has them; large brands rank from 4. Our how we work page explains the choice of these five and why we give no mark out of ten.
Free-forever core plugin with Plus pricing by number of sites
Ranked #1 of 13 in Best WordPress Security Plugins in 2026.
Free tierPublished pricingElsewhere
The free edition already carries two-factor login, password policies, core file scanning and a vulnerability scanner, which is rare at zero cost.
Plus climbs in seven site bands up to one hundred sites and adds traffic rate limiting, CrowdSec intelligence, passkeys, MainWP integration and seven days plus twelve weeks of backup retention. Weigh that against the missing corporate details: nothing on the pages read identifies who stands behind the plugin.
What stands out
Free core hardening
Site-count bands
CrowdSec in Plus
Where it costs you
The About page gives no country, legal entity, address or owner, so a procurement check has nothing to verify.
The agency tier is only listed as coming soon, so agencies must price Plus by site band for now.
Right for
Single sites and small portfolios wanting a capable free tier before paying
Wrong for
Buyers who need a named company and country on record
Not stated by the vendorFree forever core; Plus billed monthly or yearly by site band, in euros; agency tier listed as coming soon
Dutch-registered plugin with three yearly licences by domain count
Ranked #2 of 13 in Best WordPress Security Plugins in 2026.
Pricing on requestEurope
Tiers differ only in how many domains they cover, so nobody pays extra to unlock the firewall, two-factor login, login attempt limits or security headers. The package also covers 18 hardening features, recurring vulnerability scans and Let's Encrypt SSL when needed.
A 30-day refund replaces a trial. The entity is registered in Groningen with a Chamber of Commerce number, which is more than most rivals publish, though no owner is named.
What stands out
Domain-count licences
18 hardening features
Groningen entity
Where it costs you
Advertised prices apply to the first year only, so the renewal bill is higher than the headline.
The page does not describe the WordPress.org version, so what you get before paying is unclear.
Right for
Owners of one to twenty-five domains wanting every feature in every licence
Wrong for
Teams wanting a documented free version to try first
NetherlandsYearly licences by domain count, shown in dollars or euros, with first-year discounts and a 30-day refund
US-registered plugin offering unlimited free sites and paid per-site packs
Ranked #3 of 13 in Best WordPress Security Plugins in 2026.
Free tierPublished pricingNorth America
The free edition is not limited by site count, which suits anyone running a long tail of small installs. Paid plans add cloud protection on top of malware scans, integrity checks, geographic access rules and spam protection, while the five-site pack brings round-the-clock premium support.
Billing can be quarterly for one site or monthly for the pack, and cancelling is allowed at any time. Ownership beyond the company name stays unstated.
What stands out
Free unlimited sites
Cloud protection
GEO access rules
Where it costs you
Two-factor authentication is not among the listed plan features, only a documentation link.
Paid plans stop at five sites, so larger portfolios have to stack packs.
Right for
Owners of many small sites wanting geographic rules at no cost
Wrong for
Buyers who require built-in two-factor login listed in the plan
United StatesFree edition for unlimited sites; paid single-site plan billed quarterly or yearly, five-site pack monthly or yearly
Test-driven plugin with a free edition and 14-day Pro trial
Ranked #4 of 13 in Best WordPress Security Plugins in 2026.
Free tierPublished pricingElsewhere
Pro bundles a cloud firewall with country blocking, malware and core file scanners, vulnerability monitoring, login limits, a custom login URL, WooCommerce abuse protection and scheduled email reports with webhooks.
Prices climb through four site bands to one hundred sites, and plans of 25 or more add white-label branding. The About page is unusually direct about two companies, one that built it and one that sells it.
What stands out
50+ security tests
White-label from 25 sites
Card-backed trial
Where it costs you
The Pro trial requires a card or PayPal and converts to annual billing unless cancelled before day 14.
No country is stated, although owner and maker are both named.
Right for
Agencies managing 25 or more sites wanting white-label reports and branding
Wrong for
Buyers who dislike trials that demand a card up front
Not stated by the vendorFree WordPress.org edition; yearly Pro in four site bands; card-backed trial; 30-day refund
Rapid mitigation without code changes, sold as per-site licences
Ranked #5 of 13 in Best WordPress Security Plugins in 2026.
Pricing on requestElsewhere
The pitch is mitigation without code changes, with API integrations and remote software management for people running many sites.
The Developer plan includes three seats; additional seats and batches of five sites are priced separately, so an agency bill grows with headcount as well as installs. Enterprise adds extended API endpoints. A first-month offer is shown, though the page does not call it a trial.
What stands out
Rapid mitigation
Extra seats and sites
Enterprise SLA
Where it costs you
Enterprise, agency and web host pricing is not published, so those buyers must contact sales.
The About page names no country, owner or legal entity, only a copyright line.
Right for
Agencies wanting vulnerability fixes applied across client sites without touching plugin code
Wrong for
Site owners who expect a free tier to start on
Not stated by the vendorDeveloper plan billed annually with seats and extra sites priced separately; enterprise tiers by contact
Free scanner tier with paid cleanup plans for one or five sites
Ranked #6 of 13 in Best WordPress Security Plugins in 2026.
Free tierPublished pricingElsewhere
Detection costs nothing, which lets you see whether a site is infected before paying. Cleanup and the real-time firewall wait on Repair, and Fortify adds hourly scans, WebHost suspension recovery, an annual website audit and 60 days of activity logs.
Support response improves with each step, from 72 hours to 24 and then six. Plans bill annually per site pack of one or five.
What stands out
Weekly free scans
Automated cleanup
Built by BlogVault
Where it costs you
The free plan does not remove malware, and support there answers within 72 hours.
The footer credits BlogVault, but no owner or country is stated.
Right for
Owners who want detection at zero cost and pay only after an infection
Wrong for
Teams that need a stated company and country on file
Not stated by the vendorFree tier with weekly scans; annual plans for one or five sites; 14-day refund window
WPMU DEV plugin with free and Pro editions sold by site count
Ranked #7 of 13 in Best WordPress Security Plugins in 2026.
Free tierPublished pricingElsewhere
Defender covers scanning, firewall and login hardening in one plugin, with pwned password checks, CAPTCHA options and user-agent blocklists among the named items.
Pro tiers differ mainly in site count, while Premium Pro adds unlimited backups, a CDN, hosting discounts, unlimited seats and 24/7 support. A free edition provides core protection. The promotional monthly rate for Premium Pro changes after three months.
What stands out
AntiBot firewall
Login masking
Plugin-suite bundle
Where it costs you
The unlimited-site tier is a bundle of other WPMU DEV Pro plugins, so security is only part of what you pay for.
No country or owner is stated on the page.
Right for
Agencies already using WPMU DEV products across many client sites
Wrong for
Buyers wanting a standalone security product and nothing else
Not stated by the vendorFree edition; yearly Pro tiers by site count; bundled Premium Pro for unlimited sites; 30-day refund
Malware and blacklist scanning plans with expert removal on higher tiers
Ranked #8 of 13 in Best WordPress Security Plugins in 2026.
Pricing on requestElsewhere
This is a scanning service more than an in-dashboard guard: it checks a site from outside and from the server, using heuristics, and tracks listings on Google Safe Browsing and dozens of other blacklists.
Recovery support comes with those listings. Escalation is by tier, from the monthly entry plan to yearly Premium and then Emergency, which buys speed. The footer names Quttera Ltd. and nothing more.
What stands out
Heuristic scanning
Blacklist monitoring
Expert removal
Where it costs you
Expert cleanup is reserved for the Premium and Emergency plans, not the entry tier.
The pricing page does not price the WordPress plugin, which sits behind a separate link.
Right for
Owners with a blacklisted site needing outside help with removal
Wrong for
Buyers who want the plugin itself priced on the page
Not stated by the vendorMonthly entry plan and yearly Premium and Emergency plans; WordPress plugin linked separately
Hosted firewall and cleanup service billed yearly per site
Ranked #9 of 13 in Best WordPress Security Plugins in 2026.
Published pricingElsewhere
The value is the service wrapped round the firewall: manual malware cleanups with no stated cap, blocklist removal, a post-cleanup report and round-the-clock ticket support.
Scans run every 12 hours, every six, or every 30 minutes on Business. Firewall-only plans bill monthly, with SSL support added on Pro. A free Sucuri Security plugin is promoted separately from the paid platform.
What stands out
Cleanup SLA
CDN firewall
GoDaddy-owned
Where it costs you
It is offered through GoDaddy Media Temple, Inc., so independence is not available here.
Multi-site owners must step up to Junior Dev or a quote, since core platform plans protect one site.
Right for
Owners of one high-value site wanting a cleanup guarantee in hours
Wrong for
Buyers who prefer independent vendors or run many sites
Not stated by the vendorYearly platform plans and monthly firewall plans, both published; 30-day money-back guarantee
Monthly website protection tiers from a Sectigo business unit
Ranked #10 of 13 in Best WordPress Security Plugins in 2026.
Published pricingElsewhere
The ladder is easy to read: Basic as the entry tier, Pro for patching, bot blocking, backdoor protection, DDoS protection, WAF and CDN, and Business for two-factor login, PCI reporting and tailored WAF rules.
Monthly billing suits short projects. A scan link is offered, but it is a check and not a plan. SiteLock describes itself as part of the Sectigo family since 2021.
What stands out
Monthly tiers
PCI reporting
Sectigo unit
Where it costs you
Annual prices are not shown, so the two-month saving cannot be checked on the page.
It sits inside Sectigo as a business unit, which removes independence.
Right for
Shops needing PCI reporting and a firewall on monthly terms without commitment
Wrong for
Buyers who want an independent vendor or a trial period
Not stated by the vendorMonthly tiers published; two months off when paying annually, though annual prices are not shown
Scanner plugin from Automattic, with paid Pro and Complete bundles
Ranked #11 of 13 in Best WordPress Security Plugins in 2026.
Free tierPublished pricingElsewhere
Start with the scanner alone, then judge whether the paid bundles justify their cost. Pro and Complete price in euros per month, per year or per two years, and yearly plans carry a 14-day refund while monthly ones get seven days.
The upgrade buys more than protection, since the bundles belong to the wider Jetpack suite. Free firewall protection is manual, so tuning stays with you.
What stands out
Daily automated scans
Automattic product
Bundled upgrades
Where it costs you
Real-time scanning and automatic firewall rules need the Pro or Complete bundles.
Automattic owns the product, so it is a large company's offer.
Right for
Existing Jetpack users wanting daily scans with no setup fuss
Wrong for
Buyers seeking a security-only product from a small independent maker
Not stated by the vendorFree scanner plugin; Pro and Complete bundles billed monthly, yearly or every two years in euros; refund windows
Vulnerability database and CLI scanner, with API plans by quote
Ranked #12 of 13 in Best WordPress Security Plugins in 2026.
Free tierPublished pricingElsewhere
Treat it as an input to your own process. The command-line scanner runs without the API, while the Enterprise plan adds instant email alerts, details by vulnerability ID, Slack and HTTP webhooks and CVSS risk scores.
Commercial use means asking for a quote, since the free tier excludes it. Because it only reports, remediation and blocking come from other products. Automattic is named as the owner.
What stands out
Vulnerability database
CLI scanner
API alerts
Where it costs you
The Researcher tier covers non-commercial use only and allows just 25 calls daily.
It supplies data and alerts, which makes it a supporting tool beside a firewall.
Right for
Security teams and developers feeding vulnerability data into their own tooling
Wrong for
Site owners wanting something that actively blocks attacks
Not stated by the vendorFree researcher tier capped by daily API calls; enterprise plan on request
Scanner and penetration-testing plans billed monthly or yearly
Ranked #13 of 13 in Best WordPress Security Plugins in 2026.
Pricing on requestElsewhere
Plans split into scanner, cloud and pentest lines, each with monthly or yearly billing and custom enterprise tiers. Pentest Auto is described as autonomous, while Pentest Expert adds manual testing by certified experts.
The one-week trial of the DAST scanner costs a small fee and needs no card commitment. Because the focus is testing and not blocking, it complements a plugin more than it replaces one.
What stands out
Pentest plans
DAST scanner
Paid trial
Where it costs you
The plans listed are scanners and pentests, so WordPress-specific protection is not what is sold.
The one-week trial carries a fee, so evaluating it costs money.
Right for
Companies that need a penetration test report for a WordPress site
Wrong for
Owners seeking an everyday firewall plugin for daily protection
Not stated by the vendorScanner, cloud and pentest plans billed monthly or yearly; enterprise on custom terms; one-week paid trial
A WordPress security plugin protects a site from attacks by limiting logins, filtering bad traffic, scanning files for malware and flagging vulnerable plugins, themes and core versions. These are the questions that actually differ between vendors, in the order we would ask them.
01
Work out how much a sales call is worth to you
4 vendors on this page sell by quote, while 9 publish a pricing model you can read today: Shield Security, WP Cerber, Security Ninja, MalCare, Defender, Sucuri, SiteLock, Jetpack Protect, WPScan.
02
Decide how much the jurisdiction matters
Check the vendor's home market (Elsewhere 11, North America 1, Europe 1), because that is where subpoenas and data requests arrive first, whatever region holds your files.
Choosing a WordPress security plugin: firewall, scanner or data feed
The word security covers three different jobs here. Shield Security, Really Simple Security and WP Cerber sit inside your dashboard and harden logins, block bots and scan files. Sucuri runs a hosted firewall with a CDN in front of the site. WPScan is a vulnerability database and command-line scanner that reports problems but blocks nothing, and Patchstack sells rapid mitigation of flaws without code changes.
Buy the job you lack, because a data feed does not stop a login attack and a login limiter does not tell you which plugin is exposed. Most small sites need a hardening plugin first, then an alert source. An agency with many client sites may want a mitigation service on top, which Patchstack sells per licence.
List which of hardening, scanning, firewall and vulnerability alerts you already have
Check whether the product blocks threats or only reports them
Confirm the feature you need sits in the tier you are pricing
Pricing WordPress security plugins for many sites
Per-site pricing decides the bill once you pass three or four installs. Shield Security prices seven site bands from 1 to 100, Security Ninja four bands, Defender tiers of 1, 3 and 10 sites plus an unlimited bundle, and Really Simple Security covers 1, 5 or 25 domains. WP Cerber lets the free edition run on unlimited websites, which changes the maths for a long tail of small sites.
Check whether the advertised price is a first-year discount, as at Really Simple Security, and whether support or white labelling sits in a higher band. Build the three-year total for your actual site count, then compare it with what the paid tier of a free edition adds.
Count your sites and note the nearest pricing band
Ask what the renewal price is after any first-year discount
Compare the free editions on 2FA, scanning and firewall rules
Malware cleanup plans: who removes the infection
Detecting malware and removing it are sold separately. MalCare scans weekly on its free plan but starts cleanup at the Repair plan, while Quttera reserves expert removal for Premium Security and Emergency. Sucuri bundles unlimited manual cleanups with a stated response commitment that tightens from 30 hours to 6 as the tier rises.
If your site earns money, response time matters more than the scan interval, so compare how fast each service promises to act. Also ask whether cleanup is automated or done by a person, and whether a report follows. Scanners such as Jetpack Protect tell you what is wrong, and the fix remains yours unless you move to a paid bundle. Treat any cleanup promise as a service level to be compared, not an assumption.
Find the lowest tier that actually includes malware removal
Compare stated cleanup response times, not only scan frequency
Check for a post-cleanup report and the limit on manual fixes
Who stands behind your WordPress security plugin
A security plugin gets deep access to your site, so ownership is worth a minute. Sucuri operates through GoDaddy Media Temple, SiteLock sits in Sectigo as a business unit, and Jetpack Protect and WPScan come from Automattic. MalCare is built by BlogVault, and Security Ninja names WebFactory Ltd as maker and Larsik Corp as owner since 2019.
At the other end, Shield Security and Patchstack give no country, legal entity or owner on the pages read. Really Simple Security publishes a Groningen entity with a Chamber of Commerce number. Independence is a preference, not a safety guarantee, but an unnamed publisher is a gap to close before you install, and a corporate parent is a fact to weigh.
Note the named company and any parent on the vendor site
Ask support for a legal entity and country if none is shown
Decide whether a corporate owner or an anonymous maker concerns you more
What goes wrong most often when buying wordpress security plugins software
Buying a scanner and assuming it blocks attacks, when WPScan and similar data services only report.
Reading a first-year price as the running cost, as with the discounted Really Simple Security licences.
Choosing a free MalCare-style tier and expecting removal, which starts only on a paid cleanup plan.
Paying for a bundle such as Defender Premium Pro or Jetpack Complete when only the security piece is needed.
