VARTA AG is a German-based company specializing in energy storage solutions, offering a range of products including modular DC high-voltage storage systems and AC complete systems with integrated battery inverters. The company emphasizes quality manufacturing in Germany, sustainability, and customer-centric services such as installation support and a dedicated monitoring portal (VARTA.energy). The website is professionally designed using TYPO3 CMS, featuring rich multimedia content and clear navigation tailored for both consumers and installers. Security posture is strong with HTTPS, cookie consent mechanisms, and no visible vulnerabilities, although explicit security policies and incident response contacts are not prominently published.

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 X-Frame-Options header

      Prevents clickjacking attacks

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

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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

VARTA AG holds a strong market position in the energy sector, focusing on innovative energy storage solutions for residential and commercial customers. Their business model includes manufacturing, sales, installation support, and digital services via their portal. The company targets environmentally conscious consumers and professional installers, leveraging German manufacturing quality as a key differentiator. The website's comprehensive product details, warranty information, and financing/funding tools indicate a customer-focused approach. Social media integration and active content updates suggest ongoing engagement and brand building. The absence of WHOIS data warrants verification but does not detract from the overall credible business presence.

Security posture

The website employs HTTPS with a presumably strong SSL configuration and includes security best practices such as cookie consent and reCAPTCHA for forms. However, explicit security headers like X-Frame-Options and Content-Security-Policy are not clearly visible in the provided data. No vulnerabilities or exposed sensitive data were detected. The lack of a published security policy or vulnerability disclosure program limits transparency. Incident response contacts are not found, which could be improved to enhance trust and readiness. Overall, the security posture is good but could benefit from enhanced transparency and formalized policies.

Recommendations

  1. Publish a clear security policy and vulnerability disclosure program on the website.
  2. Add explicit security headers such as X-Frame-Options and X-Content-Type-Options to HTTP responses.
  3. Make incident response and abuse contact information easily accessible.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities.
  5. Enhance WHOIS transparency or provide verification to improve domain trust.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, indicating a mature technical infrastructure. It uses modern web technologies including JavaScript, embedded video content, and Google Tag Manager for analytics and marketing. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with some large media assets but overall good SEO optimization. The technical stack supports a professional and scalable digital presence, though hosting provider details are not disclosed. Opportunities exist to improve security headers and incident response mechanisms.
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.
