TLDR: If you run a WordPress site, your baseline security should cover four things: (1) keep WordPress, plugins, and themes updated on a schedule, (2) use multi-factor authentication (MFA) and strong access control, (3) keep reliable backups you can restore quickly, and (4) reduce preventable risk with a few operational habits (least privilege, reputable plugins, monitoring, and a simple incident plan). The goal is not “perfect security.” It is practical risk reduction that fits a small business.
Why WordPress security feels confusing for small businesses
Most small businesses are not trying to become security experts. They just need their website to stay online, keep working, and not become a surprise problem on a busy Tuesday. The issue is that “WordPress security” is often explained in extremes. Some advice is overly technical, and some advice is overly simplistic.
A more useful approach is to treat security like building maintenance. You are not trying to make a building indestructible. You are trying to reduce avoidable risks, keep the basics working, and ensure that if something goes wrong, recovery is predictable.
This article focuses on a baseline security posture that is realistic for Canadian small businesses and still applies if you operate across Canada and the US. It also aligns with how ongoing WordPress maintenance and managed hosting typically support security in the real world.
What you are actually protecting
When people say “secure your WordPress site,” they are usually talking about protecting a few specific assets:
- Site access: Admin logins, editor accounts, and hosting control panels.
- Site integrity: Preventing unauthorized changes to pages, redirects, or injected spam.
- Customer and staff data: Contact form entries, quote requests, user accounts, and email addresses.
- Business continuity: Keeping the site available and recoverable after an incident or failure.
- Reputation and trust: Avoiding browser warnings, malicious redirects, or being used to send spam.
Security becomes clearer when you map these assets to the practical controls that protect them.
The most common ways WordPress sites get compromised
Most incidents are not movie-style “hacking.” They usually happen through routine weaknesses:
- Outdated software: WordPress core, plugins, or themes that are behind on security patches.
- Credential compromise: Reused passwords, leaked passwords, phishing, or brute-force login attempts.
- Too much access: Multiple admin accounts, shared logins, or accounts that never get removed.
- Risky extensions: Plugins or themes that are abandoned, poorly maintained, or installed from untrusted sources.
- Recovery gaps: Backups that do not exist, are not restorable, or are stored in the wrong place.
The baseline controls in the next sections address these patterns directly.
Baseline #1: Updates and patching (core, plugins, themes)
If you only do one thing consistently, do this: keep WordPress core, plugins, and themes up to date. The WordPress project itself emphasizes updates as a key part of basic security, and encourages using plugins and themes that are actively maintained.
For a small business, “updates” should mean an operational routine, not a once-a-year burst of activity. A practical approach looks like this:
Set a regular update cadence
- Weekly: Review and apply routine plugin and theme updates, then do a quick site check.
- Monthly: Confirm WordPress core updates, review extensions, and remove anything unused.
- After major changes: Update again once the site has stabilized, especially if new plugins were added.
Update safely, not recklessly
Updates can occasionally cause compatibility issues. The goal is to reduce risk without creating new disruption. Basic safeguards include:
- Backup first (more on this below).
- Update in a controlled order: plugins first, then themes, then core, unless a specific advisory suggests otherwise.
- Do a quick functional check: homepage, a key service page, contact form, and any ecommerce or booking flow.
- Keep a short change log: date, what changed, and whether anything required a rollback.
Reduce update risk by reducing plugin sprawl
Many WordPress problems come from having too many plugins that overlap in function. A smaller, well-maintained plugin set is easier to keep current and easier to troubleshoot. As a baseline:
- Remove plugins you are not using.
- Avoid installing multiple plugins that do the same job “just in case.”
- Prefer reputable sources and plugins with a clear update history.
Baseline #2: MFA and account hygiene (stop credential-based takeovers)
For many small businesses, the fastest path to a serious incident is a compromised login. Multi-factor authentication (MFA) addresses this directly by requiring an additional factor beyond a password. Canada’s Canadian Centre for Cyber Security and other security agencies consistently recommend MFA as a strong baseline control for accounts.
Where MFA matters most
Enable MFA anywhere that provides meaningful control or access:
- WordPress admin accounts (especially administrators)
- Hosting control panel and server access
- Email accounts (because password resets often route through email)
- Domain registrar accounts (control of DNS can redirect traffic and email)
- Cloud storage used for backups and business documents
Use MFA that matches your risk
Not all MFA methods are equal. Some methods are more resistant to phishing than others. Without getting overly technical, a practical preference order often looks like this:
- Best: security keys or passkeys where supported
- Strong: authenticator apps (time-based codes or push approvals)
- Better than nothing: SMS codes (use when other options are not available)
The most important point is consistency. A strong password alone is not enough if it is reused, leaked, or phished.
Make access control boring and predictable
Small teams commonly share logins because it is convenient. That convenience creates risk and accountability gaps. Baseline access control should include:
- Unique accounts per person (no shared admin logins).
- Least privilege: give people the minimum role they need (Editor instead of Admin, when possible).
- Remove access quickly: when staff change roles or leave, remove accounts and revoke keys.
- Use a password manager: it supports unique, strong passwords without relying on memory.
Baseline #3: Backups that you can actually restore
Backups are not only for cyber incidents. They also protect you from updates gone wrong, accidental deletions, hosting failures, and human error. The common mistake is assuming “we have backups” without confirming that restores work.
What to back up (minimum)
- Database: posts, pages, settings, form entries, ecommerce orders, and user data.
- Files: WordPress core files, themes, plugins, uploads, and any custom code.
The 3-2-1 thinking, simplified for small business
A useful mental model is to keep multiple copies in different places. In practice, this often means:
- A recent backup on the hosting environment for quick restores.
- A separate copy stored off-site (cloud storage) in case the hosting environment is the problem.
- Enough retention to roll back beyond yesterday, because some issues are discovered late.
Decide your recovery targets
Two questions help you choose a backup schedule that makes sense:
- How much data can you afford to lose? If your site gets several inquiries per day, losing a week of form submissions is not acceptable.
- How quickly do you need the site back? If the site is a primary lead channel, recovery time matters.
You do not need a perfect answer, but you do need an intentional one.
Test restores, not just backups
A backup that cannot be restored is not a backup, it is a false sense of security. Baseline practice:
- Confirm you can restore the database and files.
- Do an occasional test restore into a staging environment.
- Document where backups are stored, who can access them, and how restores happen.
Baseline #4: Hosting and configuration basics that reduce exposure
Security is shared responsibility. WordPress configuration, hosting environment, and business operations all matter. Without turning this into a server administration guide, these are baseline expectations you should be able to ask about and verify:
- TLS/HTTPS: Your site should run on HTTPS, and admin logins should never be transmitted in plain text.
- Account separation: Avoid running unrelated sites in a way that allows one compromised site to affect others.
- Server and platform patching: The underlying operating system and services should be maintained and patched.
- Access logging and monitoring: You should be able to review login activity and identify anomalies.
- Principled access: Limit who has server-level access and rotate credentials when needed.
Managed WordPress hosting often helps here by standardizing patching, access controls, isolation, and monitoring practices. It does not eliminate the need for WordPress-level maintenance, but it can reduce the operational burden for small teams.
Baseline #5: Reduce risk from plugins, themes, and third-party scripts
WordPress sites are ecosystems. The moment you install plugins, themes, and tracking scripts, you expand your attack surface. That is normal. The baseline is to manage it intentionally.
Choose extensions like you choose suppliers
- Prefer actively maintained plugins and themes.
- Avoid “nulled” or pirated software. It is a common path to malware.
- Keep a short approved list of core plugins your business relies on.
- Remove what you do not need. Disabled but installed plugins are still part of your footprint.
Be careful with “just add this script” requests
Marketing pixels, chat widgets, and analytics scripts are common. They can also be a source of risk if they are added without review or if accounts are compromised. Baseline practice:
- Track what is installed and why.
- Use least privilege on third-party accounts.
- Remove scripts you no longer use.
Baseline #6: Monitoring, alerts, and simple operational habits
Most small businesses do not need a security operations centre. They do need a small set of signals that warn them early. Baseline monitoring includes:
- Uptime monitoring: know when the site is down.
- Login alerts: especially for admin accounts or unusual locations.
- File change awareness: unexpected changes can indicate compromise.
- Form and email monitoring: sudden spikes in spam or delivery failures can be a sign of trouble.
Operationally, keep it simple:
- Document who is responsible for updates and when they happen.
- Keep a list of critical vendor logins (domain registrar, hosting, email) and who has MFA enabled.
- Record key renewal dates (domain, SSL, hosting, critical plugins).
Baseline #7: Have a small incident plan before you need it
When something goes wrong, the first hour matters. You do not need a 40-page plan. You need a short checklist that avoids panic and preserves evidence for troubleshooting.
- Step 1: Identify what is happening (defaced pages, redirects, admin lockout, warnings, downtime).
- Step 2: Limit exposure (change passwords, revoke sessions, disable compromised accounts).
- Step 3: Preserve access and logs (do not delete everything immediately).
- Step 4: Restore from known-good backups if appropriate.
- Step 5: Patch the cause (updates, plugin removal, credential resets, configuration fixes).
- Step 6: Review what happened and reduce repeat risk.
If your business handles sensitive data, you may also have notification obligations depending on the situation and applicable privacy requirements. The baseline approach is to know who you would call (internal lead, IT provider, legal/privacy advisor) and where the evidence is (logs, backups, change history).
How WordPress maintenance supports these basics
Many businesses treat security as something they will “deal with later.” In practice, security is mostly consistency: updates, checks, backups, and access control. This is where WordPress maintenance matters.
A practical WordPress maintenance program commonly includes:
- Scheduled updates for WordPress core, plugins, and themes
- Pre-update backups and the ability to roll back if needed
- Monitoring for availability and key site functions
- Routine audits of user accounts and permissions
- Periodic cleanup of unused plugins and themes
- Documentation and change tracking
Whether you do this internally or outsource it, the important part is that it is owned and consistently executed.
A practical baseline checklist you can use
If you want a short list to work from, start here:
- Enable MFA on WordPress admin accounts, hosting, email, and domain registrar.
- Use unique logins per person and remove unused accounts.
- Use a password manager and stop password reuse.
- Update WordPress core, plugins, and themes on a schedule.
- Remove unused plugins and themes, and avoid untrusted sources.
- Confirm backups exist, are stored appropriately, and can be restored.
- Monitor uptime and basic security signals (logins, anomalies).
- Write a one-page incident checklist and keep it accessible.
When it is time for a rebuild, not just maintenance
Sometimes security issues are a symptom of an older site that has accumulated too many plugins, custom patches, and one-off changes over the years. If your site is difficult to update safely, it may be a candidate for a rebuild that simplifies the architecture, reduces plugin dependencies, and creates a more maintainable foundation.
A rebuild is not automatically “more secure,” but a cleaner, more maintainable system is often easier to keep updated and easier to monitor.
