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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. 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

Solarwatt holds a strong market position as a supplier of German photovoltaic products in Spain and other European markets, leveraging a multi-country website network. Their business model focuses on providing complete solar energy systems, including hardware and energy management solutions. The company benefits from partnerships and sister sites across Europe, enhancing brand consistency and market reach. The use of advanced marketing and analytics tools suggests a data-driven approach to customer engagement and growth. However, the absence of direct contact information on the main site may limit immediate customer interaction. The company appears medium-sized with a focus on renewable energy sectors.

Security posture

The website exhibits a good security posture with HTTPS enabled and cookie consent mechanisms that allow granular user control. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security hardening. There is no visible security policy or incident response contact, which could hinder timely vulnerability reporting and response. Compliance with GDPR is supported by the cookie consent banner but lacks a detailed privacy policy. Overall, the security maturity is moderate to good but could be enhanced by formalizing security policies and improving header configurations.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service to improve transparency and compliance.
  2. Add security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Provide clear contact information including emails and phone numbers for customer support and security incident reporting.
  5. Regularly audit third-party scripts and cookies to minimize privacy risks and ensure compliance with evolving regulations.

Technical notes

Notes

The website is built on the Neos CMS platform using the Flow PHP framework, indicating a modern and flexible content management system. It employs Google Tag Manager and Cookiebot for analytics and cookie consent management, reflecting a mature approach to data collection and privacy. The site loads CSS and JavaScript resources asynchronously and uses modern font formats (woff2), contributing to good performance and mobile optimization. However, some performance improvements could be achieved by optimizing third-party scripts and reducing cookie counts. Accessibility is basic but could be improved with enhanced ARIA roles and keyboard navigation support. SEO is supported by proper meta tags, Open Graph, and JSON-LD structured data, although the structured data is minimal and could be expanded for richer search results.
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.
