Your WordPress site does not need to be a fortress to be secure, but it does need a few fundamentals in place. Most successful attacks on small business sites exploit obvious weaknesses: an outdated plugin, a reused password, a hosting plan with no firewall. Fix those and you have removed the low-hanging fruit that automated bots constantly go after.
Key takeaways
- Outdated plugins and themes are the most common entry point for attackers on WordPress sites.
- A weak admin password plus no two-factor authentication is an open invitation to brute-force attacks.
- Layering protections (good hosting, a security plugin, regular backups, SSL) is far more effective than any single fix.
- You do not need to be technical to action most of this, your website maintenance plan should cover it automatically.
- Doing a security review once and walking away is not enough; set a quarterly reminder.
Start with your hosting, everything else sits on top of it
If the server your site runs on is poorly configured, no amount of plugins will fully compensate. Look for a host that includes a firewall, automatic malware scanning, and daily backups as standard. Shared hosting is fine for many small businesses, but it does mean your site shares resources with others, which carries some risk. A VPS (Virtual Private Server) gives you more isolation if you are handling sensitive customer data.
Whatever plan you are on, confirm that automatic backups are actually running and that you know how to restore from one. A backup you cannot restore is not a backup.
Keep WordPress, plugins and themes updated
This sounds obvious, but it is the single biggest gap on most small business sites. Every update WordPress or a plugin developer releases often includes a security fix. Leave it unapplied and you are running software with a known vulnerability, and attackers know which ones to target.
The process is straightforward in your WordPress dashboard under Dashboard > Updates. For plugins and themes, you can enable automatic updates so critical patches apply without you having to remember. Just make sure you have a backup before any major update runs, so you can roll back if something breaks.
Also, delete plugins and themes you are not actively using. An inactive plugin still represents a potential entry point, even if it is switched off.
Use a security plugin and an SSL certificate
A security plugin like Wordfence or Sucuri adds a firewall, monitors login attempts and scans for malware, things WordPress does not do by default. Install one, configure it properly and check in on its alerts occasionally.
An SSL certificate (the padlock in the browser) encrypts data between your site and your visitors. Without it, browsers warn visitors your site is not secure, which will cost you enquiries. It also has a small but real positive effect on your search rankings. Most hosting providers include a free SSL certificate, if yours does not, that is worth querying.
Sort your admin credentials
Brute-force attacks work by trying thousands of username and password combinations. If your admin username is literally "admin" and your password is short or reused from another account, this is a serious exposure. Change your username to something non-obvious, use a password that is at least 12 characters and generated by a tool like 1Password or Bitwarden, and enable two-factor authentication (2FA) on your WordPress login.
Many security plugins include 2FA support, or you can use a dedicated plugin. It adds about ten seconds to logging in and makes brute-force attacks essentially useless.
Spam protection matters more than you think
Spam in your contact forms and comments is not just annoying. Links to malicious sites posted in your comments can get your site flagged by search engines. Akismet is the most widely used spam filter for WordPress, install it, get an API key, and it runs quietly in the background filtering the junk.
A simple priority order if you're starting from scratch
- Confirm your host has a firewall, malware scanning and daily backups.
- Update WordPress core, all plugins and all themes.
- Delete any plugins or themes you are not using.
- Change your admin username and set a strong, unique password.
- Enable two-factor authentication on admin accounts.
- Install an SSL certificate if you do not have one.
- Install a security plugin (Wordfence or Sucuri are solid choices).
- Add Akismet for spam filtering.
- Set a quarterly reminder to repeat steps 2, 5 and 8.
| Step | Difficulty | Done by |
|---|---|---|
| Update WordPress and plugins | Easy | You or your developer |
| Strong passwords plus 2FA | Easy | You |
| SSL certificate | Easy to medium | Your host or developer |
| Security plugin setup | Medium | Your developer |
| Backup configuration check | Medium | Your host or developer |
| File permissions review | Technical | Your developer |
You should not be doing all of this yourself
If you are running a business, your time is better spent elsewhere. Most of the ongoing work here, checking updates, monitoring for threats, verifying backups, is exactly what a website maintenance plan handles for you. The point is not that you cannot do it, it is that you probably should not have to.
Get the basics locked down once, then make sure someone is keeping an eye on it going forward. That is a much better use of everyone's time than scrambling after a hack.

Frequently asked questions
How often should I update my WordPress plugins?
As soon as updates are available, ideally. Most security patches are released in response to discovered vulnerabilities, so delay increases your exposure. Enable automatic updates for plugins you trust, and check manually at least once a month.
Do I need a security plugin if my host already has malware scanning?
Both do different jobs. Your host protects at the server level, but a WordPress security plugin monitors activity inside your site, login attempts, file changes, injected code. Having both is the sensible approach.
What is the biggest cause of WordPress sites getting hacked?
Outdated plugins are consistently the most common entry point, followed by weak admin passwords. Keeping everything updated and using strong, unique credentials eliminates a large proportion of the risk.
Can I secure my WordPress site myself or do I need a developer?
Some steps, updating plugins, changing passwords, installing an SSL certificate, are well within reach for a non-technical business owner. Others, like reviewing file permissions or configuring a security plugin properly, are quicker and more reliable when handled by someone who knows WordPress.
