Myth: WordPress Is Secure Out of the Box. Reality: 92% of Small-Business Sites Fail Basic Security.
You trust WordPress because it powers 43% of the web. You launch a new site—fresh install, strong password, SSL enabled. Job done, right?
We scanned 49,604 sites across 44,791 unique small-business WordPress installs. Only 0.1% scored an A+. Nearly half failed outright. Most business owners never see the red flags. Attackers see them instantly.
If you believe “default WordPress is safe,” the real data from your peers should stop you cold. Here’s why that belief puts your revenue, your customer data, and your reputation at risk.
The Myth
❌ Myth: WordPress is secure out of the box
Most owners believe a fresh WordPress install gets security “by default.” It’s fast. It’s popular. The famous 5-minute install ends with a login screen and a welcome post. That first impression sells the idea that you can launch and forget.
After all, if millions rely on WordPress, it can’t be a security risk—can it?
The Data
We analyzed 49,604 scans across 44,791 unique small-business WordPress sites in the past 30 days.
Average security score: 39.1%.
Only 65 sites—just 0.1%—earned an A+.
Grade Distribution:
| Grade | Number of Sites | Percentage |
|---|---|---|
| A+ | 65 | 0.1% |
| A | 117 | 0.2% |
| B+ | 516 | 1.0% |
| B | 300 | 0.6% |
| C+ | 5,823 | 11.7% |
| C | 3,048 | 6.1% |
| D | 13,175 | 26.6% |
| F | 22,683 | 45.7% |
92% of sites scored C or lower.
Nearly half failed completely—leaving doors open to attackers and bots.
Breakdown of critical security controls:
- SSL/TLS Configuration ('Good'): 7.2%—Valid certificate, HSTS, modern TLS, strong ciphers.
Most sites have HTTPS. Very few have it hardened against intercepts or downgrade attacks. - Security Headers ('Good'): 0.4%—All required: CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy.
Missing headers mean browsers don’t protect your sessions or customer logins. - Cookie Security ('Good'): 88.4%—Session cookies set Safe/SameSite/HttpOnly flags.
- Mixed Content ('Good'): 77.2%—No insecure (HTTP) resources loaded in.
- Server Version Exposure: 20.6%—Server reveals exact software version. This gift wraps your site for attackers who match versions to known exploits.
This isn’t a single developer’s failure. This is systemic.

The Breakdown
The real data exposes four deadly assumptions that most business owners make about WordPress security.
Myth: "A Fresh WordPress Install Covers the Basics"
Reality: Default installs miss almost every critical security hardening measure.
Data: 45.7% of sites fail outright. Only 7.2% have SSL truly locked down. Only 0.4% set all required security headers. Cookie security is the only area where most fare well—and that’s a fluke, not intent.
Business consequence: Basic attacks like session hijacking, content injection, and credential theft work against most sites from day one. A fresh WordPress install doesn't block these. Attackers don’t need zero-days—they use what’s exposed.
Myth: "HTTPS Means My Site Is Secure"
Reality: HTTPS only encrypts data in transit. Most “secure” padlocks on browsers hide misconfigurations.
Data: 7.2% have proper SSL/TLS setup. The rest lack HSTS or strong ciphers, leaving them open to interception and downgrade attacks.
Business consequence: Users trust the padlock. Attackers bypass weak SSL. If your login or admin panel isn’t locked down, credentials and credit card details leak—without warning.

Myth: "Security Headers Are for Large Sites—My Customers Don’t Need Them"
Reality: Missing headers leave browser defenses unarmed—no matter your size.
Data: Only 0.4% set all required security headers (CSP, X-Frame-Options, etc.). 99%+ miss at least one.
Business consequence: Your customers are one click from cross-site scripting payloads. If malware infects your checkout or login, Google flags you and payment processors shut you down.
Myth: "Attackers Don’t Care What Version I Run"
Reality: If you leak your server version, attackers know exactly how to break in.
Data: 20.6% expose server version banners. Automated bots scan and target these weaknesses dozens of times per hour.
Business consequence: Outdated server software, known exploits, and automated attacks become personalized threats. This risk doesn’t require a high-profile target—only a site left exposed.

What to Do Instead
Security isn’t automatic. Here’s what works—fast:
- Harden immediately after install. Run a security checklist to plug known gaps.
- Demand “Good,” not “Present,” on SSL/TLS.
- Set a valid certificate, enforce HSTS, enable only modern TLS, strip out weak ciphers.
- Set ALL required security headers.
- CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy.
Don’t rely on “secure by default.” - Eliminate mixed content warnings.
- Scan for HTTP scripts and images. Fix all found issues.
- Lock down server version leaks.
- Remove banners and meta tags that reveal your stack.
- Review cookies and session settings.
- Require Secure, HttpOnly, and SameSite on all sensitive cookies.
- Scan, audit, and repeat.
- Run your site through a security scanner after every update.
- Don’t assume plugin or theme defaults protect you.
- For a quick-action plan, see our website security checklist.
- Limit admin access to people who need it. Use strong, unique passwords.
- Keep all plugins, themes, and WordPress core updated. Outdated components account for the majority of exploited breaches (details for SMBs).
Final Thoughts
The myth of “secure out of the box” puts every small-business WordPress site at risk. Our scans of 44,791 real-world sites prove it: over 92% earn failing or barely passing grades. The defaults protect only by accident, not by design.
Stop assuming. Start acting.
Run your site. See your security grade.
