WordPress Security Plugins: The 8 Best in 2026
WordPress is the most widely used CMS in the world, and therefore also the most attacked. According to W3Techs, 40.2% of all websites run on WordPress (October 2026), and among sites with a known CMS the share is 58.6%.
A good security plugin is your first line of defence. But which one should you choose?
In this guide I compare eight plugins so you can pick the one that fits your site.
Seven of them are dedicated security plugins. The eighth is Jetpack, which bundles many features and puts security in a paid plan. I include it because a lot of sites already run Jetpack, and I state clearly what it gives you and what it does not.

What should a security plugin do?
A good WordPress security plugin should include:
The essentials
- Firewall (WAF): blocks malicious traffic before it reaches your site
- Malware scanning: finds infected files and malicious code
- Login protection: limits login attempts and blocks brute force attacks
- Two-factor authentication (2FA): an extra layer at login
- Alerts: an email when something is wrong
Nice to have
- File change detection
- Hardening of the WordPress setup
- Blocklist monitoring
- SSL certificate monitoring

Patchstack
Active installations: 60,000+ Price: Free plugin (vulnerability alerts) / Developer $69 per month billed annually ($828 per year)
What Patchstack does
Patchstack works differently from classic security plugins. Rather than scanning files on your server, it protects against known vulnerabilities in plugins, themes and WordPress core, even before the developer has released a fix:
- Virtual patching (paid): targeted rules that block exploitation of a known vulnerability without changing the site's code
- Early warnings (free): up to 48 hours' notice of new vulnerabilities found by Patchstack's researchers
- RapidMitigate: Patchstack says it prevents up to 74% more vulnerabilities from being exploited than leading web application firewalls (Patchstack's own figure)
- Extras in the paid version: 2FA, hardening, a community IP blocklist and custom rules
- Remote management: update vulnerable plugins and follow all your sites from one place
Pros
- Protects against vulnerabilities before an update exists
- Light to run, because rules are only deployed when a vulnerability is found on the site
- Good for agencies and freelancers with many sites
Cons
- The free version only gives alerts, not protection
- No malware scanning. Patchstack states that it will not find malware already on the site
- The price is high for a single site
Who is it for?
Best for: agencies and freelancers who look after several WordPress sites, and anyone who would rather prevent than clean up.
Wordfence Security
Active installations: 5+ million Price: Free / Premium $149 per year per site / Care $590 / Response $1,250
What Wordfence does
Wordfence is the most installed security plugin on WordPress.org and offers:
- Firewall (WAF): blocks known attack patterns
- Malware scanner: compares your files with the official versions and looks for known malicious code
- Login security: brute force protection, 2FA, passkeys and reCAPTCHA
- Live traffic: see visits and attacks in real time
- Country blocking (Premium): block traffic from specific countries
Pros
- Very complete free version
- Detailed firewall with rules
- Thorough malware scanning
- Updated continuously
Cons
- New firewall rules and malware signatures arrive 30 days later in the free version
- Scanning uses your server's resources
- The interface can feel overwhelming
Who is it for?
Best for: anyone who wants solid security for free, and anyone who wants detailed control.
Kadence Security (Nexcess)
Active installations: 700,000+ Price: Free / the Pro features come with the Kadence Pro bundle at $299 per year or Elite at $499
What Kadence Security does
Kadence Security makes security manageable with templates for different types of site:
- Security dashboard: attacks, banned users and scan results at a glance
- Brute force protection: a network of nearly 1 million sites plus your own blocklist
- 2FA: several methods, such as an app, email and backup codes
- Passwordless login (Pro): users log in with one click
- Virtual patching (Pro): the Pro version includes Patchstack
Pros
- Friendly setup, which Kadence says takes under 10 minutes
- Good 2FA
- Patchstack included in Pro
Cons
- Many features need Pro
- Pro is sold as part of the Kadence bundles, not as a standalone plugin on the pricing page
- Malware scanning is not mentioned in the plugin description
Who is it for?
Best for: sites that already use the Kadence theme or blocks, and beginners who want a simple setup.
Sucuri Security
Active installations: 600,000+ Price: Free plugin / platform from $229 per year (Basic), $339 (Pro), $549 (Business)
What Sucuri does
Sucuri combines a free plugin with a paid cloud firewall and CDN:
- Security activity log: everything that happens on the site
- File integrity monitoring: spots changes that should not happen
- Remote malware scanning: scans from Sucuri's own servers
- Blocklist monitoring: an alert if your site gets blocklisted
- Cloud firewall (paid): filters traffic before it reaches your server and protects against DDoS
- Malware removal (paid): included in the platform plans
Pros
- The firewall does not load your server
- CDN included in the paid plans
- Post-hack cleanup is included
Cons
- The plugin alone gives limited protection
- More expensive than the alternatives
- The firewall requires a DNS change
Who is it for?
Best for: larger sites and online shops that want CDN and security in one package.
All-In-One Security (AIOS)

- Firewall: basic on the free plan, extended with virtual patching on Protect
- Login protection: 2FA for 2 admin users on the free plan
- Malware cleanup (Repair and up): instant cleanup and a report afterwards
Pros

Cons
- Cleanup needs at least Repair at $299 per year
- The free plan only scans weekly
Who is it for?
Best for: anyone who prioritises malware protection, and sites that have been hacked before.
SecuPress
Active installations: 40,000+ Price: Free / Pro, priced by number of sites and monthly or annual billing
What SecuPress does
SecuPress is a French plugin focused on simple setup:
- Security scanner: checks 35 points and fixes them for you
- Firewall: blocks bad bots and suspicious IP addresses
- Login protection: against brute force and password spraying
- Malware scanner (Pro)
- PDF security report (Pro)
Pros
- Clean, clear interface
- The scanner can fix its findings and asks first when a decision is needed
- PDF report you can send to a client
Cons
- Smaller user base than Wordfence
- Malware scanning and reports need Pro
Who is it for?
Best for: anyone who wants a simple setup with a good interface.
Jetpack
What it is: One plugin from Automattic with many features: stats, backups, search, AI, speed and security. Security is not a separate plugin but a paid plan inside Jetpack, and it needs a WordPress.com account.
Price: The plugin itself is free. Jetpack Security costs DKK 67.95 per month for the first year and DKK 134.95 per month after that, both billed yearly (as shown from Denmark on 3 October 2026).
What Jetpack's security does
- Brute force protection: free
- Downtime monitoring: free
- Firewall (WAF): in the Security plan
- Real-time backups and restores: in the Security plan, from 10 GB storage
- Malware scanning with one-click fixes: in the Security plan
- Spam filtering via Akismet: in the Security plan
- 30-day activity log: in the Security plan
Pros
- From Automattic, the company behind WordPress.com
- Backups, firewall and malware scanning alongside stats
- The free tier covers brute force and downtime
Cons
- A heavy plugin if all you need is security
- Firewall and malware scanning need the paid plan
- Needs a WordPress.com account, so data passes through Automattic's services
Who is it for?
Best for: sites that already run Jetpack and want backups, firewall and malware scanning from the same vendor. If you are choosing a security plugin from scratch, Patchstack or Wordfence are lighter for the job.
Which plugin should you choose?
Best overall: Patchstack
Patchstack is the strongest choice when you look after many sites. Virtual patching protects against known vulnerabilities before an update exists. The price is $828 per year for the Developer plan, though, and it will not find malware that is already in. Pair it with a free malware scanner.
Best free: Wordfence
Wordfence free is the most complete free option, with firewall, malware scanning and login protection. Remember that the rules arrive 30 days later than in Premium.
Best for Kadence sites: Kadence Security
If you already have Kadence Pro, you have Kadence Security Pro with Patchstack built in, so it makes sense to use it.
Best with a CDN: Sucuri
For larger sites that want a cloud firewall and CDN with cleanup included, Sucuri is worth considering.
Best on a small budget: AIOS
AIOS covers the basics for free, and Premium is cheap if you need malware scanning.
Best for malware: MalCare
If the site has been hacked before, MalCare is built to find and remove malware.
If you would rather not run this yourself
Picking a plugin is the easy part. The hard part is that one of them has to be set up properly, and someone has to notice when an update breaks the setup three months later.
That is the part I handle in WordPress maintenance: updates, hardening and one person accountable for the whole setup rather than a licence key. See the prices (maintenance from DKK 2,500/month, technical partner DKK 15,000/month), or tell me what you are running into and I will tell you whether it is worth fixing.
If you are unsure where to start, the security baseline for small businesses covers the basics beyond WordPress.
Conclusion
A good security plugin matters for any WordPress site. My advice:
- Start with Wordfence free. It is genuinely good, and it costs nothing to find out whether you need more.
- Add Patchstack if you run client sites. At $828 per year, though, it is a deliberate cost.
A plugin is not enough on its own. Use strong passwords, keep everything updated and take regular backups.
Frequently asked questions
What is the best free security plugin for WordPress?
Wordfence is the most complete free option, with a firewall, a malware scanner and 2FA. The free version gets new firewall rules and malware signatures 30 days late. Real-time updates need Premium, which costs $149 per year per site.
How much does Patchstack cost?
The Developer plan is $69 per month billed annually, so $828 per year, with 3 team seats. Extra sites come in packs of 5 for $12.50 per month. The free plugin gives you vulnerability alerts but not the automatic protection.
Can I run several security plugins at once?
Use one plugin for firewall and login protection. Two plugins that both filter traffic and lock logins can get in each other's way and make troubleshooting hard. Patchstack is the exception, because it focuses on vulnerabilities and itself recommends running a malware scanner alongside it.
Will a security plugin remove malware that is already on my site?
Not always. Patchstack does not scan files for malware. Wordfence, MalCare and Sucuri can find malware, but cleanup is a paid service: at MalCare from the Repair plan at $299 per year, at Wordfence from Care at $590 per year.
Isn't my hosting enough?
A good host blocks a lot, but it rarely tells you which of your own plugins has a known vulnerability, and it does not clean up files that are already infected. A security plugin and regular updates cover those gaps.
