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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 small but important entity in the hospitality and real estate sectors, leveraging partnerships with local stakeholders and the municipality. Its revenue model likely includes promotional partnerships, ticket sales, and city branding initiatives. The target audience includes local residents, tourists, and entrepreneurs. The platform's partnership ecosystem includes related domains such as schiedamviert750.nl for city celebrations. Growth indicators include active event promotion and digital engagement. The business benefits from a clear market niche as the official city marketing channel.

Security posture

The website demonstrates a moderate security maturity level with HTTPS and secure form submissions. However, it lacks comprehensive security headers like Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. There is no visible vulnerability disclosure or incident response information, which could hinder timely security issue reporting. Privacy compliance is partial, missing cookie consent mechanisms. No critical vulnerabilities or exposed sensitive data were detected. The security posture is adequate but could be improved with additional headers and published policies.

Recommendations

  1. Implement a Content-Security-Policy header to enhance protection against cross-site scripting.
  2. Add security headers such as X-Frame-Options and X-Content-Type-Options to improve defense in depth.
  3. Publish a clear security policy and incident response contact information to facilitate vulnerability reporting.
  4. Introduce a cookie consent banner or mechanism to comply with GDPR and ePrivacy regulations.
  5. Regularly review and update third-party libraries and frameworks to mitigate known vulnerabilities.

Technical notes

Notes

The website uses a mature CMS platform (DotNetNuke) combined with popular JavaScript libraries like jQuery, Bootstrap, and Owl Carousel, providing a stable and feature-rich user experience. The site includes SEO best practices such as meta descriptions and alternate language links. Performance is moderate, with some optimization opportunities. Mobile responsiveness is good, but accessibility features are basic and could be enhanced. The technical stack is well-suited for the site's purpose but would benefit from modern security enhancements and performance tuning.
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.
