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

      Third-party services without privacy policy

      Detected services: Google Analytics

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

  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 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';…

  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 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

Caruna holds a significant market position as a major electricity network operator in Finland. Its business model focuses on electricity distribution and customer service for both residential and business clients. The company leverages digital self-service platforms to enhance customer experience and operational efficiency. The website content and WHOIS data confirm the legitimacy and transparency of the business. The company does not appear to have publicly listed subsidiaries or parent companies in the provided data. The use of AWS for hosting and modern analytics tools indicates a commitment to scalable and data-driven operations.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, multiple security headers, and no exposed sensitive information. The presence of cookie consent and privacy policies indicates compliance with GDPR requirements. However, the absence of a published security policy, incident response contact, or vulnerability disclosure program suggests areas for improvement in transparency and incident readiness. No critical vulnerabilities or suspicious patterns were detected in the website content or WHOIS data. Overall, the security posture is solid but could be enhanced by publishing additional security governance documentation.

Recommendations

  1. Implement DNSSEC to strengthen DNS security and prevent spoofing.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Establish and publicize a vulnerability disclosure program or security.txt file.
  4. Enhance transparency by providing direct contact details for the Data Protection Officer or privacy team.
  5. Regularly review and update third-party scripts and tracking tools to minimize privacy risks.

Technical notes

Notes

The website is built on Drupal 10, a modern and secure CMS platform, hosted likely on AWS infrastructure as inferred from the nameservers. It uses Google Tag Manager and Instana for analytics and performance monitoring, alongside Giosg for live chat support and OneTrust for cookie consent management. The site is mobile-optimized, accessible, and SEO-friendly with proper meta tags and Open Graph data. Performance is moderate, with room for optimization. The technical stack is modern and well-maintained, supporting a professional user experience and operational reliability.
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.
