How does your WordPress security measure up against information security standards—such as ISO 27001, the BIO, or NEN 7510? First, let’s clear up a common misconception: using WordPress doesn’t mean you’ll “suddenly” be compliant; compliance isn’t a switch you can just flip. But if your organization is subject to such a standard, your website is often a key component of it. After all, it’s a place where data enters and where your security must be demonstrable. In this blog, you’ll learn which standards are relevant, which standard applies to which type of organization (rarely does a single organization need them all), why compliance always has two sides—your site’s technology and your hosting—how to speed up your preparations with AI, and how we handle it at JKC. One clarification up front: we’ll largely set aside the GDPR here. It deals with privacy and personal data—a related but distinct discipline from information security.
Is Your WordPress Security Sufficient for Information Security?
WordPress has an undeserved reputation for being insecure. The truth is: WordPress security is no more or less a matter of the system itself than it is with other platforms—it depends on how you set it up and manage it. With the right technology, processes, and hosting, a WordPress site is perfectly capable of meeting strict information security standards. It’s important to understand that a standard like ISO 27001 applies to your entire organization, not just your website. So your website alone will never make you compliant. Conversely, however, the site is often one of the components that falls within the scope of the standard—and must therefore be demonstrably in order. Compliance isn’t a switch you flip, but a process you establish and demonstrably maintain.
What Weak WordPress Security Costs You
Information security may sound abstract, but the risks directly affect your own website. Imagine this: a major client asks you to sign a security statement or pass a supplier audit, and you can’t prove that your site is up to standard. Then that contract falls through over a single checkbox. Or you fail to win a healthcare or government contract because you can’t demonstrate compliance with the required standard. These are the direct costs of weak WordPress security: lost revenue and reputational damage. On top of that comes the privacy aspect: if you process personal data via a contact form, newsletter, or online store, the GDPR also applies—with its own risk of a data breach and a fine from the Dutch Data Protection Authority. Related regulations also directly affect your site, such as the European Accessibility Act. And this isn’t just an issue for large organizations: these requirements also apply to freelancers and small and medium-sized businesses as soon as you process data online. Good WordPress security is therefore not a luxury, but a way to protect your revenue and your reputation.
Which standards are we talking about?
This blog focuses on three information security standards. We’ll set the GDPR aside for now, since it deals with privacy rather than information security:
| Standard | What is this about? | For whom |
|---|---|---|
| ISO 27001 | International Standard for Information Security | Those who want to demonstrably ensure security (often corporate) |
| BIO | Government Information Security Baseline (at the ISO 27001 level) | The government and those who work for the government |
| NEN 7510 | Information Security in Healthcare (NEN) | Healthcare organizations and their suppliers |
| GDPR (privacy, not information security) | Protection of Personal Data (Dutch Data Protection Authority) | Any organization that holds personal data |
Important: It’s rare for a single organization to need all of these standards at the same time. Which one applies to you depends on your industry and your role—usually, it’s exactly one. A healthcare provider looks to NEN 7510, a government contractor to the BIO, and a corporate entity to ISO 27001. The GDPR is the exception that affects almost everyone, but it stands on its own: it is privacy legislation, not an information security standard.
Which standard affects whom? Here's how to know what to look out for
Not every standard applies to every organization—and in most cases, there’s exactly one information security standard that applies to you. What you need to focus on regarding your WordPress security depends on your industry and your role. If you recognize yourself in any of these situations, you’ll know right away which standard applies to you:
- Marketing or communications manager at a larger organization (healthcare, medtech, corporate). You need to secure internal buy-in from executive management, IT, and sometimes QA or legal. In the healthcare sector, this involves NEN 7510; in a corporate environment, it’s often ISO 27001. Your priority: being able to demonstrate that the supplier can handle it, so that you don’t run into problems internally.
- You’re a growing entrepreneur, and a major client suddenly starts making demands. A client asks for an integration, a portal, or a security statement. That’s when ISO 27001 comes into play. What’s at stake for you: not losing the contract because of a box you can’t check.
- Government agency or government contractor. In that case, the BIO applies, which in practice is equivalent to the ISO 27001 standard.
- Any organization with a contact form or account. As soon as you process personal data, the GDPR also applies. Please note: this pertains to privacy, not information security—it’s a separate requirement that runs parallel to your information security standards.
The common thread: information security is rarely an abstract requirement, but rather something that a specific person—whether internally or at a client’s site—must be able to defend. If you know which standard applies to you, you’ll also know what to discuss with your web developer and your hosting provider.
Compliance always has two aspects: technology and hosting
This is the key point that’s often overlooked. Compliance for a website is always the sum of two things. On the one hand, there’s the technical aspect of the site itself: who has access to what data, how long you retain data, how you log access, and how you prevent data breaches. On the other hand, there’s the infrastructure and hosting: does your site run on an environment with the proper certifications, and do those providers have verifiable procedures in place? You can have the technical aspects perfectly in order, but if you’re using a hosting provider without certification, you’re still not compliant. And the reverse is just as true.
WordPress Security: What to Do at the Technical Level
- Minimum permissions — not everyone needs to be an administrator.
- Strong authentication — for example, two-step verification for administrators.
- Retention Policy — Specify how long you retain form and customer data and when you purge it.
- Encryption and Updates — Use HTTPS everywhere, and keep your software (core, plugins, theme) up to date.
- Logging — recording who did what and when, so you can provide proof.
- Agreements — data processing agreements and a proper cookie and consent policy.
What You Can Expect from Your Hosting Provider
Ask your hosting provider specifically about: their certifications (such as ISO 27001), how often they perform backups, how they respond to incidents, where the servers are located, and who has access. A reputable provider will back this up with documentation. If your healthcare or government website runs on an environment that cannot demonstrate this, that is a risk separate from your own technology.
Prepare Your Information Security with AI: Prompts You Can Use Right Away
AI doesn't take over your information security, but it does help you fine-tune your preparations: taking stock, asking the right questions, and identifying gaps. You can copy these prompts and fill in the blanks between the square brackets:
- Mapping Data: “I have a WordPress site with the following features: [contact form, quote form, account, newsletter, online store, …]. Create an overview of what data each feature collects, where that data is stored, and which of those are sensitive.”
- Hosting Questionnaire: “Create a list of specific questions I should ask my hosting provider to verify whether they comply with [ISO 27001 / NEN 7510], regarding certifications, backups, incident response, data location, and access.”
- Establishing a retention policy: “Draft a retention policy for these types of data: [form submissions, accounts, newsletters]. For each type, specify a standard retention period and when it makes sense to purge the data, so that I can align it with my own legal requirements.”
- Identifying Gaps: “These are the security measures I’m currently implementing: [paste list]. Compare them with the key areas outlined in [the standard] and note where I still have gaps and what questions I need to ask my web developer.”
Important: Use the results as a starting point, not as a final assessment. Information security ultimately comes down to people: have your approach reviewed by your web developer, your hosting provider, and, where necessary, a security expert or auditor. AI helps you have the right conversation, but it doesn’t sign off on anything.
The Master's Application Prompt: Get Ready in One Go
Would you prefer a structured preparation guide all at once instead of separate prompts? Copy the prompt below into your AI tool (ChatGPT, Claude, or another), fill in your specific situation, and you’ll receive a preparation document that you can finalize with your web developer, hosting provider, and, if necessary, an auditor.
You’re an information security consultant. Help me prepare my WordPress site for an information security standard. You won’t be providing a final assessment, but rather a preparation plan that I’ll have reviewed. My organization: [industry + number of employees] The standard that applies to me: [ISO 27001 / BIO / NEN 7510 — and/or GDPR for privacy] Components on my site that collect data: [contact form, account, newsletter, online store, ...] My current measures: [list what you’re currently doing, or ‘I don’t know’] Please provide: 1. A data inventory: for each component, what data it collects, where that data goes, and what is sensitive. 2. A draft retention policy for each type of data, with a standard retention period (to be aligned with my own legal requirements). 3. A questionnaire for my hosting provider (certifications, backups, incident response, data location, access). 4. A gap analysis: which measures are missing compared to the standard, and what questions I need to ask my web developer. 5. A short checklist with priorities (now / soon / later). First, ask up to 3 clarifying questions if anything is missing.
Once again: this is preparation, not a final judgment. That’s also in line with how we view AI (humans steer, AI accelerates): you can read more about that in our vision on AI. The results will help you have more focused discussions with your web developer, hosting provider, and auditor, but the final decision remains a human one.
Helpful tip: An AI integration can scan your entire WordPress site at once for issues such as missing security measures, outdated plugins, or forms without the correct settings—instead of having to check page by page. To learn how to safely integrate AI with your site, read “WordPress Management in 2026: Put AI to Work.”
Here's How JKC Approaches WordPress Security
At JKC, we are committed to the BIO standard. In practice, this is equivalent to the ISO 27001 standard, and we are in the process of obtaining ISO 27001 certification ourselves. Specifically, this means: we set up sites with minimal access rights, a well-thought-out retention policy, and logging, and we choose hosting providers that can demonstrate the appropriate certifications and procedures. This ensures that information security is demonstrably embedded in both the technology and the infrastructure—not just a promise made after the fact.
Compliance is never just your website or just your hosting. It is the sum of both, documented in a verifiable manner. If one of the two is missing, the picture isn't complete.
Frequently Asked Questions About WordPress and Information Security
Which standard applies to my organization?
Usually exactly one, depending on your industry and your role. Healthcare organizations and their suppliers are subject to NEN 7510, government agencies and their suppliers to BIO, and corporate environments often choose ISO 27001 to demonstrably ensure security. Rarely does a single organization need all of them. Separate from these is the GDPR: it applies to every organization that processes personal data, no matter how small you are, but that is privacy legislation and not an information security standard. In practice, therefore, you often have one information security standard that fits your sector, plus the GDPR as a privacy baseline alongside it.
What is the difference between information security and the GDPR?
Information security (ISO 27001, BIO, NEN 7510) is about protecting information in the broadest sense: controlled access, logging, retention policies, and certified infrastructure, to ensure that data is not leaked, altered, or rendered unavailable. The GDPR specifically addresses privacy: the lawful and careful handling of people’s personal data. They overlap—good security helps you ensure your privacy is in order—but they are two separate disciplines with their own requirements. For your WordPress site, this means: you handle information security (technology + hosting) and, if you process personal data, you handle the privacy aspects separately (data processing agreements, consent, retention periods). This blog focuses on the former.
Is WordPress secure enough for the healthcare sector (NEN 7510)?
Yes, provided it’s set up properly. WordPress isn’t inherently less secure than other systems; it depends on how you set it up and manage it. NEN 7510 requires controlled access (minimal privileges, strong authentication), logging that allows you to demonstrate who did what and when, a well-thought-out retention policy, and hosting that supports these requirements with certifications. With this setup, a WordPress site is a perfectly acceptable component within the standard. The key is to document these measures in a verifiable way, not to choose a different CMS.
What is the difference between BIO and ISO 27001?
ISO 27001 is the international standard for information security, focused on establishing and maintaining an information security management system. The BIO (Government Information Security Baseline) is the Dutch government baseline that is based on ISO 27001 and closely aligns with it in practice. Those who comply with the BIO are, in practice, operating at the ISO 27001 level. For a website, both standards entail the same requirements: controlled access, logging, retention policies, and certified hosting.
Does having a WordPress site automatically make me compliant?
No. An information security standard such as ISO 27001, the BIO, or NEN 7510 covers your entire organization—processes, people, technology, and suppliers—not just your website. So your website alone will never make you compliant. However, if your organization is subject to such a standard, the website is often a specific component within its scope: it’s a place where data is received, and where you must demonstrate that your security measures are in order. You therefore manage the website as part of a larger whole, not as the entire solution.
Is information security the responsibility of my website or my hosting provider?
Both, and that’s the key point that’s often overlooked. Your site’s technical infrastructure determines who has access to which data, how long you retain data, how you log access, and how you prevent data breaches. Your hosting provider determines the underlying security: certifications, backups, incident response, and server locations. You can have your site’s technical infrastructure perfectly organized, but if your hosting provider lacks certification, you’re still not compliant—and the reverse is just as true. Information security is the sum of both, documented in a verifiable manner.
