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

5 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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

Vantaa.fi positions itself as a key government information hub for the city of Vantaa, offering a wide range of public services and engagement opportunities. The business model is public sector service delivery, focusing on transparency and citizen engagement. The site supports multiple languages, indicating inclusivity and internationalization. While no direct revenue streams are evident, the site supports municipal operations and community outreach. The presence of detailed organizational and governance information suggests a commitment to accountability. Partnerships or subsidiaries are not explicitly listed, consistent with a municipal government entity.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS, comprehensive security headers, and cookie consent mechanisms aligned with GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure program indicates room for improvement in transparency and readiness. The use of third-party analytics and monitoring tools is balanced with privacy compliance. Overall, the security posture is good but could be enhanced by publishing explicit security governance documents and contact channels for security incidents.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Establish and publicize an incident response contact channel (e.g., security@vantaa.fi or abuse@vantaa.fi).
  3. Implement and link to a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Regularly review and audit third-party scripts to mitigate supply chain risks.
  5. Enhance transparency on data retention and processing policies related to analytics and user data.

Technical notes

Notes

The site is powered by Drupal 10, a modern and widely supported CMS, ensuring maintainability and security updates. It uses Google Tag Manager and Instana for analytics and performance monitoring, indicating a focus on operational insight. The site is mobile-optimized with responsive design and accessibility features such as skip links and ARIA labels. SEO is supported by proper meta tags and Open Graph data. Performance appears moderate, likely due to comprehensive content and third-party scripts. No critical technical debt or deprecated technologies were observed. Hosting details are not explicit but the presence of security headers and HTTPS indicates a professionally managed environment.
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.
