Their website is professionally designed using WordPress, featuring clear navigation, good SEO practices, and mobile optimization.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

4 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The company operates in the Real Estate sector, targeting homeowners and clients needing construction and renovation services. Their business model focuses on service delivery with a local market presence. The website content and structured data reflect a clear and consistent brand identity. Trust indicators include certification as an 'Erkend Leerbedrijf' and transparent contact information. No evidence of partnerships or subsidiaries was found. The company appears to maintain a straightforward operational model with a focus on quality and reliability.

Security posture

The website uses HTTPS and secure contact forms, which are positive security indicators. However, the absence of security headers such as Content-Security-Policy and Strict-Transport-Security reduces the overall security posture. No incident response or security policy information is provided, and no vulnerability disclosure or security.txt files are present. The lack of cookie consent mechanisms may pose GDPR compliance risks. Overall, the security maturity is moderate with room for improvement in headers and compliance transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Enable DNSSEC on the domain to enhance DNS security.
  3. Add a cookie policy and consent mechanism to comply with GDPR requirements.
  4. Publish a security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit and update plugins and dependencies to avoid vulnerabilities.

Technical notes

Notes

The website is built on WordPress with common plugins like Contact Form 7 and uses modern front-end libraries such as Swiper.js for sliders. Google Fonts are used for typography. The site loads moderately fast and is mobile optimized. SEO is well implemented with meta tags, Open Graph, and JSON-LD structured data. Accessibility is basic but present. Hosting provider details are not explicitly disclosed. No analytics or tracking scripts were detected, indicating minimal user tracking. The technical stack is standard for small business websites, with opportunities to enhance security and privacy features.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
