“WordPress is insecure.” You’ve heard this a hundred times. But here’s a question: If WordPress is so insecure, why does the White House use it? Why does NASA? Why do banks and governments worldwide? Let’s separate myth from reality.
The Big Myth
The myth goes like this: WordPress is open-source, so hackers can see the code and find vulnerabilities. Custom software is secret, so it’s safer.
This is backwards.
Open-source software is reviewed by thousands of security researchers. Vulnerabilities are found and fixed quickly. Custom software hides its bugs until a hacker finds them.
“Security through obscurity is not security at all.”
— Security industry saying
Where Do WordPress Vulnerabilities Come From?
Here’s the most important statistic you need to know:
97% of WordPress vulnerabilities come from plugins and themes — not WordPress core.
WordPress core is extremely secure. It’s maintained by Automattic and a dedicated security team. It receives regular updates. It follows security best practices.
The problem is third-party code. A free plugin made by one developer in their spare time is not the same as WordPress core.
| Source | % of Vulnerabilities |
|---|---|
| Plugins | ~90% |
| Themes | ~7% |
| WordPress Core | ~3% |
The White House Uses WordPress
The official White House website has been built on WordPress. This is the digital presence of the President of the United States.
Do you think the White House would use insecure software? They have:
- The Secret Service reviewing security
- The NSA providing guidance
- Constant attacks from nation-state hackers
- Zero tolerance for security failures
If WordPress was truly insecure, the White House would not use it. Full stop.
NASA Uses WordPress VIP
NASA uses WordPress VIP for their blogs and microsites. WordPress VIP is the enterprise-grade hosting platform that powers some of the world’s biggest sites.
WordPress VIP includes:
- 24/7 security monitoring
- Automatic security patches
- Code review for all plugins
- DDoS protection
- Regular security audits
This is not your average shared hosting. This is enterprise security.
How to Make WordPress Secure
WordPress security is not automatic. It requires proper setup. Here’s how the enterprise does it:
1. Use Quality Hosting
Cheap shared hosting = shared security problems. Enterprise sites use:
These hosts include firewalls, malware scanning, and automatic updates.
2. Minimize Plugins
Every plugin is a potential security risk. Enterprise sites:
- Use only necessary plugins
- Choose well-maintained plugins with good reviews
- Remove unused plugins completely
- Audit plugins regularly
3. Keep Everything Updated
Most hacks target old, unpatched vulnerabilities. Updates are critical:
- Enable automatic WordPress core updates
- Update plugins weekly
- Update themes
- Update PHP version
4. Use Strong Authentication
- Strong, unique passwords
- Two-factor authentication (2FA)
- Limit login attempts
- Change default admin username
5. Implement Web Application Firewall (WAF)
A WAF blocks attacks before they reach your site:
Custom Software Is Not More Secure
Here’s what people forget: Custom software has security issues too. The difference?
WordPress Vulnerabilities
- Publicly reported
- Quickly patched
- Security researchers help
- Community monitors
Custom Software Vulnerabilities
- Hidden until exploited
- Only your team can fix
- No external review
- You discover bugs the hard way
“Custom development often wins on TCO while providing better performance and security, though this can vary based on project complexity.”
— Synaptis Technologies
Notice the word “can” — custom software can be more secure. But only if you invest heavily in security testing, code reviews, and ongoing maintenance. Most companies don’t.
Security Is a Process, Not a Product
The real truth about security:
No software is inherently secure or insecure. Security depends on:
- How it’s configured
- How it’s maintained
- How it’s hosted
- How users behave
A poorly maintained custom site is less secure than a well-maintained WordPress site. And vice versa.
The question is not “Is WordPress secure?” The question is “Are you doing security right?”
Enterprise Security Checklist
If you want WordPress security at enterprise level, here’s your checklist:
- ☐ Use managed WordPress hosting (VIP, WP Engine, Kinsta)
- ☐ Enable automatic core updates
- ☐ Audit and minimize plugins
- ☐ Implement 2FA for all users
- ☐ Use a WAF (Cloudflare, Sucuri)
- ☐ Regular backups (daily minimum)
- ☐ Security monitoring and alerts
- ☐ Regular security audits
- ☐ SSL/HTTPS everywhere
- ☐ Principle of least privilege for users
Follow this checklist, and your WordPress site will be more secure than 99% of custom-built websites.
Key Takeaways
- 97% of WordPress vulnerabilities come from plugins, not WordPress core
- The White House and NASA use WordPress — they wouldn’t if it was insecure
- Open-source security is better than “security through obscurity”
- Custom software has vulnerabilities too — you just don’t know about them yet
- Security is about configuration and maintenance, not the platform
