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

3 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 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 256-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

Nordic Solar operates in 12 European countries, focusing on utility-scale solar park projects and battery energy storage integration. Their competitive advantage lies in full value chain operation from greenfield development to grid connection, positioning them as a key player in the Nordic renewable energy market. Revenue streams likely include solar park operations, power purchase agreements, and energy storage solutions. The target customer segments include investors, energy market participants, and sustainability-focused stakeholders. Growth indicators include expanding battery storage projects and increasing operational MWp capacity. The company maintains a professional partnership ecosystem with active social media presence and transparent investor communications.

Security posture

The website demonstrates a mature security posture with HTTPS enforcement and no visible sensitive data exposure. Privacy and cookie policies indicate GDPR compliance and user consent mechanisms. The absence of explicit security headers and incident response contacts suggests room for improvement in defense-in-depth and transparency. No vulnerabilities or malware indicators were found in the HTML content. The company should consider publishing a security.txt file and vulnerability disclosure policy to enhance incident response readiness and stakeholder trust. Overall, the security culture appears proactive but could benefit from formalized policies.

Recommendations

  1. Implement and configure HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish an incident response contact or security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Develop and disclose a formal vulnerability disclosure policy to encourage responsible security reporting.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.
  5. Enhance user trust by providing more visible security and compliance certifications or attestations on the website.

Technical notes

Notes

The website leverages a modern React-based framework (Next.js) with server-side rendering for performance and SEO benefits. Content is managed through Sanity CMS, enabling rich media and structured content delivery. The site uses Google Tag Manager for analytics and marketing, integrated with user consent mechanisms. Performance is optimized with responsive images and lazy loading. The technical stack is up-to-date, supporting scalability and maintainability. Opportunities exist to improve security headers and incident response mechanisms to reduce technical risks and enhance operational resilience.
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.
