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

Uitjes.nl is a well-established Dutch online platform founded in 1999, specializing in providing inspiration and listings for leisure activities and day trips across the Netherlands and Belgium. The platform caters to a broad audience including families, friends, and corporate groups, offering a wide range of activities such as sports, cultural events, and special outings. It features user reviews, promotional offers, and a reservation/payment system to facilitate bookings. Technically, the website employs modern web technologies including Bootstrap, Google Analytics, Google Tag Manager, and Google reCAPTCHA, ensuring a functional and moderately optimized user experience with good mobile responsiveness. Security-wise, the site benefits from HTTPS, DNSSEC, and reCAPTCHA integration, but lacks visible security headers and published security policies, indicating room for improvement in security transparency and defense-in-depth. Overall, the domain's WHOIS data confirms a long-standing and legitimate presence, supporting the platform's credibility and trustworthiness.

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. 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

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

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

    • 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

  3. 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 384-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

Uitjes.nl holds a strong market position as a leading leisure activity finder in the Dutch hospitality sector. Its business model revolves around aggregating and promoting a diverse range of outings and events, monetizing through promotions and a reservation/payment system. The platform targets general consumers seeking day trips and leisure activities, with a focus on families and groups. Partnerships with recognized organizations such as Natuurmonumenten and Staatsbosbeheer enhance its ecosystem. The website's content quality and branding consistency support user trust and engagement, while its medium size and longevity indicate stable operations. Growth potential lies in expanding digital marketing and enhancing user engagement features.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and DNSSEC enabled, protecting data in transit and domain integrity. Integration of Google reCAPTCHA on forms mitigates automated abuse. However, the absence of security headers like Content Security Policy, HSTS, and X-Frame-Options reduces defense layers against common web attacks. No public security policy or incident response contacts are provided, which limits transparency and preparedness perception. No vulnerabilities or exposed sensitive data were detected in the analyzed content. To elevate security maturity, publishing a security policy, implementing security headers, and establishing a vulnerability disclosure program are recommended.

Recommendations

  1. Implement and configure HTTP security headers such as CSP, HSTS, and X-Frame-Options to enhance protection against common web threats.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and user trust.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerable components are included.
  5. Enhance accessibility features and SEO metadata to improve user experience and search engine visibility.

Technical notes

Notes

The website uses a modern technology stack including Bootstrap for responsive design, FontAwesome for icons, and Google services for analytics and bot protection. The HTML structure is valid and includes appropriate meta tags for SEO and social sharing (Open Graph). Performance is moderate with asynchronous loading of scripts and lazy loading of images. Mobile optimization is good, supporting a wide range of devices. However, no CMS or hosting provider details are explicitly detected. Accessibility is basic but could be improved with more ARIA attributes and semantic HTML. Overall, the technical implementation supports a stable and user-friendly platform but could benefit from enhanced security 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.
