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

9 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

  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 Strict-Transport-Security header

      Forces HTTPS connections

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

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

Tesla Energy Group operates in the energy sector, focusing on manufacturing battery storage solutions. Their business model revolves around product manufacturing and providing energy solutions to homes and companies. The company targets environmentally conscious customers seeking sustainable energy options. The website's multilingual capabilities suggest an intent to serve multiple European markets. While the company appears small in size, it maintains a consistent brand image and professional online presence. The lack of visible certifications or trust badges may indicate a developing market position or a focus on direct business relationships rather than broad consumer marketing. No explicit partnerships or subsidiaries are identified from the website content.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and no visible exposure of sensitive data. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces its defense-in-depth. No vulnerability disclosures or incident response contacts are provided, which limits transparency in security management. The use of up-to-date WordPress plugins and themes is assumed but should be regularly audited to prevent vulnerabilities. Privacy compliance is weak due to missing privacy and cookie policies, which could pose regulatory risks under GDPR. Overall, the security posture is functional but requires enhancements to meet best practices and compliance standards.

Recommendations

  1. Implement and display a comprehensive privacy policy and cookie consent banner to improve GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance security posture.
  3. Provide clear contact information including emails and phone numbers for customer and security incident communications.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to foster transparency and trust.
  5. Regularly audit and update all CMS components and plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, Google Tag Manager, and multilingual support via WPML. The site uses a custom theme or builder (Bricks Builder) and several plugins for galleries and styling. Performance is moderate with caching and CSS optimizations evident. Mobile optimization is good, and SEO meta tags are properly implemented including Open Graph and Twitter cards. Accessibility features are basic but present. Hosting provider details are not disclosed. The site lacks advanced security headers and visible privacy compliance mechanisms, which are technical gaps to address.
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.
