Website security in 2026: how to better secure your website

Securing a website is not a one-off setting you can tick off after launch. Software changes, plug-ins get updates, employees come and go, and new vulnerabilities are discovered. For a Belgian self-employed professional or SME, good website security is therefore mainly a matter of reducing risks and regular maintenance, not installing one miracle plugin and assuming everything is taken care of.

The most important basics are surprisingly down-to-earth: use reliable hosting, keep software up to date, protect admin accounts with strong unique passwords and two-factor authentication, make restorable backups, and check for strange changes or warnings. HTTPS is part of that, but HTTPS alone does not make a website “secure”.

With many business websites, things don’t go wrong because nobody knows updates and backups are important, but because nobody is truly responsible for them. Therefore, set out who follows up on notifications, who performs updates, and who can restore things when something goes wrong.

If you only have ten minutes: check this first

Check	Good sign	Action if it’s not in order
HTTPS active	Your website opens with https:// without a browser warning	Have SSL/TLS set up correctly and redirect HTTP to HTTPS.
CMS and plug-ins up to date	No overdue security updates	Make a backup first, then update in a controlled way.
Admin accounts protected	Unique password + 2FA for administrators	Renew passwords, enable 2FA, and remove old accounts.
Backup available	Recent backup in a separate location	Set up automatic backups and test recovery.
Remove unused software	Only necessary themes and plug-ins present	Remove what you don’t use, don’t just deactivate it.
Monitoring active	You’ll receive alerts about suspicious changes or malware	Set up security monitoring or a reliable scanner.
Search Console connected	You can see security warnings	Verify the property and check Security Issues.
Recovery plan clear	You know who to call and which backup to restore	Record contact details, access, and recovery steps in advance.

1. Understand what website security does and does not mean

A completely risk-free website doesn’t exist. Your goal is to reduce the chance of abuse, limit damage if something does happen, and be able to recover quickly. That is also the core of “hardening”: using multiple layers of defense instead of relying on a single measure.

For developers, the OWASP Top 10 2025 is an important reference framework for common risks in web applications. As an owner, you don’t need to know that list technically by heart. Above all, you need to ensure that your website, hosting, and custom work are maintained by someone who handles access rights, updates, input fields, and configuration securely.

• An SSL certificate protects the connection, but it doesn’t fix a vulnerable plug-in.
• A security plug-in can help, but it doesn’t replace updates, strong accounts, or backups.
• A backup doesn’t prevent a hack, but it can make the difference between recovering quickly and being offline for days.

2. Start with reliable hosting and HTTPS

Your hosting environment is the foundation of your website. A good host keeps server software up to date, limits abuse, and offers clear options for SSL/TLS, backups, and support. If in doubt, ask who is responsible for server updates, malware, backups, and recovery. “The host handles security” is too vague; you want to know where their responsibility ends and yours begins.

HTTPS is basic work by now. It encrypts traffic between visitor and website, which is important for login details, forms, and payments. After a migration or certificate renewal, also check whether all old HTTP URLs redirect correctly and whether no mixed content (“mixed content”) remains.

3. Install updates on time – but not blindly

WordPress is regularly updated to address issues and security risks. The official WordPress hardening guide recommends keeping WordPress up to date; in practice the same applies to themes and plugins.

“Update everything automatically” is not the best approach for every business website. For a simple site, it can work fine. For an online store, booking system, or custom-built website, it is wiser to have a backup first and test important functions after the update. Security and continuity go hand in hand.

• Regularly update WordPress core, themes, and plugins.
• Before major updates, check whether there is a recent backup.
• After updates, test forms, checkout, payments, login, and other critical functions.
• Replace software that is no longer maintained.

4. Use unique passwords and enable 2FA

A strong password helps most when it is unique. Using the same password across multiple services is risky: a breach at one service can then grant access to other accounts. Therefore, use a password manager and create a separate password for each admin account.

For administrators, two-factor verification (2FA/MFA) is one of the most useful extra layers. The Belgian Centre for Cybersecurity Belgium also recommends 2FA for important business access points.

• Enable 2FA for WordPress administrators, hosting, domain name, email, and other critical accounts.
• Do not share an administrator password via regular email or chat if it can be avoided.
• Create separate accounts for employees; do not work with one shared “admin”.

5. Grant users only the rights they need

Not everyone who needs to edit content has to be an administrator. The more administrator accounts exist, the greater the number of accounts that provide access to settings, plug-ins, and user management. So choose the lowest role someone can do their work with, and remove accounts as soon as someone no longer needs access.

• Check every quarter which users still have access.
• Give external suppliers their own temporary account instead of sharing your own login.
• Remove old administrators and accounts of former employees.
• Protect hosting and domain accounts with the same discipline.

6. Create backups that you can actually restore

A backup is only valuable if it is recent, complete, and restorable. WordPress recommends regular backups of both files and the database. Preferably, do not store all copies on the same server as the website; in the event of an incident, you want an independent copy. See also the official WordPress guidelines on backups.

The part that is often forgotten: test recovery. An automated “backup completed” notification does not prove that you can restore the website without issues. Especially for an online store or business site, a periodic restore test is sensible.

• Determine how often your data changes and align the backup frequency with that.
• Keep at least one copy outside the production environment.
• Make sure you know who has access to the backups.
• Occasionally test a restore in a safe test environment.

7. Remove unused plug-ins, themes and accounts

Less software means fewer components that need maintenance. A deactivated plug-in is still on the server. If you no longer need it, delete it. The same applies to old themes, test accounts and temporary integrations that remained after a project.

• Remove plug-ins and themes you don’t use.
• Check whether a plug-in is still actively maintained before adding it.
• Limit the number of tools that perform the same function.
• Only download WordPress, themes and plug-ins from reliable official or well-known sources.

8. Use a firewall and malware monitoring as an extra layer

A web application firewall (WAF) can block suspicious traffic before it reaches your website. For WordPress, solutions exist at plug-in, hosting and network level. Which approach fits depends on your hosting, traffic and risk. A security plug-in is therefore not automatically mandatory, but can be useful for login security, monitoring, malware detection and alerts.

Don’t choose a plug-in based on “how many features” it has. Too many overlapping security tools can make the website more complex or even get in each other’s way. One well-managed solution is usually better than three tools that no one follows up on.

9. Protect forms, login pages and other input points

Contact forms, login pages, search fields and comments process input from outside. That’s why they deserve extra attention. For regular business sites, it’s often mainly about spam, brute-force attempts and form abuse. In custom applications, input must also be technically validated and processed correctly.

• Limit repeated failed login attempts or use rate limiting where appropriate.
• Use anti-spam measures for forms without making the user experience unnecessarily difficult.
• Remove comment or registration functionality if you don’t use it.
• Have custom forms securely implemented and validated by a developer.

10. Keep PHP, server components, and integrations up to date

Your CMS is only one part of the technical chain. PHP, database software, server components, theme frameworks, and external integrations can also become outdated. With managed hosting, part of this is managed for you; with other packages, more responsibility lies with you or your webmaster.

Before a major PHP upgrade, always check the compatibility of themes and plugins. A secure website that stops working after an update is not a good outcome. Therefore, make a backup and test critical functionality.

Is your WordPress site not only outdated but also slow? Then read the Moonbeetle guide Speed up WordPress. Good technical maintenance often helps with stability, performance, and security at the same time.

11. Don’t set file permissions and technical configuration too loosely

File permissions determine which processes may read, modify, or execute files. Overly permissive rights make abuse easier. This is a technical area where you’re better off not changing settings on a whim: incorrect permissions can break updates, uploads, or even the entire website.

The official WordPress hardening documentation describes, among other things, file permissions and limiting write and execute rights. Have such changes carried out by someone who knows your hosting environment if you’re not sure what they do.

12. Monitor changes and check Google Search Console

Security isn’t only about prevention; you also want to spot problems quickly. Think of unexpected new administrators, changed files, strange redirects, unknown pages, or sudden spam in Google. Monitoring and log files can help detect anomalies.

Also link your website to Google Search Console. The Security Issues report can warn you when Google suspects a website has been hacked or could harm visitors. This does not replace your own security monitoring, but it is a useful extra check.

Signals you should not ignore

• New pages or search results that you did not create yourself.
• Visitors being redirected to strange websites.
• Unknown admin accounts or unexpected password resets.
• A browser warning about an unsafe or deceptive website.
• A sudden spike in outgoing traffic, spam, or server load.

13. Secure an online store more strictly than a simple informational site

An online store handles more sensitive processes than a simple brochure website. Accounts, orders, addresses, payments, discount codes, and integrations with external services increase the impact of an incident. That does not necessarily require dozens of extra plugins, but it does require stricter maintenance and faster follow-up.

• Limit admin rights and enable 2FA for everyone with access to orders or settings.
• Test checkout and payments after updates.
• Use reliable payment providers; do not store payment details that you do not need to store yourself.
• Make frequent backups and decide how you will restore recent orders if you need to roll back.
• Check integrations with accounting, shipping, email marketing, and other external services.

14. Make a plan in advance in case your website does get hacked

During an incident you do not want to start figuring out who manages the hosting or where the backups are stored. Therefore, decide in advance who has access to hosting, domain, CMS, and backups, and who you will call in when problems arise. A short recovery plan is often already sufficient for a small business.

What do you do if your website seems hacked?

1. Limit further damage: contact your host or webmaster and change critical access credentials from a trusted device.
2. If possible, make a copy of the affected environment for investigation before you overwrite everything.
3. Find the cause: restoring only an old backup without fixing the vulnerability can lead to a new infection.
4. Remove malicious code and update or replace the vulnerable component.
5. Restore from a clean backup when necessary and test all key functions.
6. Check user accounts, integrations, Search Console, and external alerts after the site is back online.

Google publishes separate documentation about malware and abuse on websites and can report security issues via Search Console. In the event of a serious incident, or for a website that processes personal data, professional security and legal advice may also be needed.

Securing a WordPress website: extra checklist for WordPress

Do you use WordPress? Then you can translate the steps above into a concrete maintenance routine. WordPress itself isn’t “unsafe” because it’s popular; the practical risks often arise from outdated components, weak accounts, overly broad permissions, or poor maintenance. Therefore, keep the installation as simple and up to date as possible.

• WordPress core is up to date.
• All active themes and plug-ins are up to date and are still being maintained.
• Unused plug-ins and themes have been removed.
• Administrators use unique passwords and 2FA.
• There are as few administrator accounts as possible.
• Automatic backups run and restoration has been tested.
• Security monitoring or an appropriate WAF is active where needed.
• PHP and the hosting environment use a supported version.
• You receive notifications from hosting, WordPress, and monitoring, and someone follows them up as well.

A simple rhythm to keep security from slipping

Moment	What to check?	Goal
Weekly or automated	Backups, critical updates, monitoring alerts	Restore quickly and don’t leave urgent risks unresolved.
Monthly	CMS, plugins, themes, forms, login, malware/security alerts	Maintain technical hygiene.
Quarterly	User accounts, 2FA, unused software, recovery test	Check access and recoverability.
After a major change	Backup, checkout/forms, integrations, performance and security alerts	Prevent a release from introducing new issues.

Security that mainly gives a false sense of confidence

• Thinking that HTTPS means the entire website is secure.
• Installing five security plugins at once without knowing what they do.
• Delaying updates for months because you’re afraid something will break, without a testing or backup plan.
• Using a shared admin account for employees and vendors.
• Keeping backups only on the same server.
• Leaving unused plugins disabled instead of removing them.
• Copying technical settings from random tutorials without checking whether they fit your hosting environment.
• After a hack, only restoring an old backup without finding the cause.

Frequently asked questions about website security

How can I secure my website?

Start with reliable hosting, HTTPS, up-to-date software, unique passwords, 2FA for administrators, regular backups, and monitoring. Remove unused software and make sure someone actually follows up on security alerts.

Is HTTPS enough to secure my website?

No. HTTPS encrypts the connection between visitor and website, but it does not protect against, for example, a vulnerable plug-in, a stolen admin account, or malicious code on the server. It is a necessary base layer, not a complete security solution.

Do I need a WordPress security plugin?

Not every website needs the same solution. A good security plugin can help with login protection, firewall features, monitoring, or malware detection, but it does not replace updates, backups, and secure accounts. Choose one suitable solution instead of stacking multiple overlapping plugins.

How often should I update a WordPress website?

Check updates regularly and install security updates in a timely manner. How you organize that depends on the website. For a simple site, automatic updates may be suitable; for an online store or custom-built site, controlled updating with a backup and function test is often wiser.

How often should I make a backup of my website?

That depends on how often the website changes. An informational site that rarely changes has different needs than an online store with daily orders. Choose a frequency where the loss since the last backup remains acceptable, and also test whether restoring works.

How do I know if my website has been hacked?

Possible signs include strange pages, unexpected redirects, unknown administrators, browser warnings, spam in Google, or suspicious monitoring alerts. Also check Search Console and your hosting or security logs.

Does website security affect SEO?

Security is not a simple “ranking trick”. A hacked site can get harmful pages, redirects, or browser warnings and therefore lose traffic and trust. A healthy, maintainable website also protects your organic visibility.

Conclusion: website security is not a setting, but a habit

Securing your website is not about one plugin or one technical trick. The strongest foundation consists of several simple measures that are carried out consistently: updates, secure access, backups, minimal permissions, monitoring, and a recovery plan. The same applies to WordPress. The simpler the installation and the better the maintenance, the more manageable the risk.
