0–100, higher is better. How it is calculated

Praktijk voor Tandheelkunde & Implantologie J.J.M. Rijnties is a small dental healthcare provider based in The Hague, Netherlands, specializing in dental implantology and general dental services. The website presents a professional but basic online presence with clear contact information and a focus on personalized patient care. The domain is well-established since 2007 with DNSSEC enabled, supporting legitimacy and trustworthiness. Technically, the site uses simple HTML and CSS without modern frameworks or CMS, resulting in moderate performance and basic mobile optimization. Security posture is limited, with no HTTPS enforcement or security headers detected, and no privacy or cookie policies present, indicating gaps in compliance and best practices. Overall, the site is safe and suitable for general audiences but would benefit from enhanced security and privacy measures to improve trust and compliance.

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

6 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

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 business operates as a local dental practice with nearly 25 years of experience, targeting patients in the Netherlands seeking implantology and dental care. The business model is service-based healthcare with direct patient engagement. The website lacks advanced digital marketing or analytics tools, indicating a traditional approach to customer acquisition. The absence of social media or partner links suggests limited digital partnerships. The domain age and DNSSEC support a stable market position, but the lack of privacy and security policies may impact future growth and regulatory compliance.

Security posture

The current security maturity is low to moderate. While DNSSEC is enabled, the absence of HTTPS enforcement and security headers exposes the site to potential risks such as data interception and clickjacking. No forms or user input fields reduce attack surface but also limit functionality. The lack of privacy and cookie policies indicates non-compliance with GDPR requirements. Incident response and vulnerability disclosure mechanisms are not present, which could delay handling of security incidents. Overall, the site requires significant improvements to meet modern security and privacy standards.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and enforce HTTPS site-wide.
  2. Add standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies to comply with GDPR and inform users.
  4. Introduce a cookie consent mechanism if cookies or tracking technologies are used.
  5. Consider adding a security.txt file and dedicated incident response contact information to improve transparency and readiness.

Technical notes

Notes

The website is built using static HTML and CSS without detectable modern frameworks or CMS platforms. The site includes a video element for visual engagement but lacks responsive design features, resulting in basic mobile optimization. No analytics or tracking scripts were found, indicating minimal data collection. Hosting provider details are not discernible from the content. Performance is moderate with no evident broken elements. SEO optimization is basic with minimal meta tags and no structured data or Open Graph tags. Accessibility features are minimal, limiting usability for users with disabilities. Overall, the technical implementation is functional but dated and could benefit from modernization and enhanced SEO and accessibility practices.
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.
