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.

    • 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

      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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Cloudflare

      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

Business profile

Ríkisskattstjóri holds a critical role as Iceland's national tax and customs authority, providing essential services such as tax and duty collection, taxpayer support, and regulatory enforcement. The website reflects a well-established government entity with a large operational scale. Its comprehensive content and service offerings indicate a robust business model centered on public sector compliance and revenue collection. The presence of certifications like Jafnlaunavottun and detailed legal and privacy documentation underscores a commitment to regulatory compliance and transparency. The site’s ecosystem includes related domains for company registration and customs services, indicating a broad partnership and service network within Iceland's government infrastructure. The digital presence supports efficient taxpayer interaction and administrative processes, positioning the authority as a key player in Iceland's financial governance.

Security posture

The website exhibits a solid security posture with mandatory HTTPS encryption and no visible exposure of sensitive data in the HTML content. The use of security scripts to prevent framing attacks and integration of a secure IBM Watson Assistant chat service further enhance security. However, the absence of explicit HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement to mitigate risks like clickjacking and MIME sniffing. No vulnerable libraries or security flaws were detected in the analyzed content. Privacy policies and data protection officer information are clearly presented, indicating good compliance with data protection regulations. Overall, the site maintains a trustworthy security environment suitable for a government tax authority, but should consider implementing additional headers and continuous security audits.

Recommendations

  1. Implement and enforce Content-Security-Policy HTTP header to reduce XSS risks.
  2. Add X-Frame-Options header to prevent clickjacking attacks.
  3. Add X-Content-Type-Options header to prevent MIME sniffing vulnerabilities.
  4. Conduct regular security audits of third-party scripts and libraries.
  5. Enhance transparency on data retention policies related to analytics and user data.

Technical notes

Notes

The website is built on the Eplica CMS platform, leveraging modern JavaScript libraries such as jQuery 2.2 and GSAP TweenMax for UI interactions and animations. It integrates Google Tag Manager and Google Analytics for tracking and Siteimprove Analytics for performance and accessibility monitoring. The IBM Watson Assistant chat integration provides advanced user support capabilities. The site is mobile optimized with responsive design and accessibility features, including ARIA roles and keyboard navigation aids. Performance is moderate, with asynchronous loading of analytics and chat scripts to minimize blocking. SEO is well addressed with proper meta tags, Open Graph, and Twitter card metadata. The technical infrastructure reflects a mature and well-maintained government digital service platform with opportunities to enhance security headers and optimize performance further.
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.
