VARTA AG is a well-established German company with a history spanning over 130 years, specializing in energy solutions including micro and household batteries, custom lithium-ion batteries, and industrial and home energy storage systems. The company targets both consumer and industrial markets, positioning itself as an innovative leader in battery technology. The website is professionally designed, built on TYPO3 CMS, and incorporates modern marketing and analytics tools such as Google Tag Manager, Google Analytics, Facebook Pixel, and Hotjar. Privacy compliance is well addressed with a comprehensive cookie consent mechanism and a detailed privacy policy.

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 operates in the energy sector with a focus on battery and energy storage solutions. Its business model revolves around manufacturing and selling a broad portfolio of energy products to both consumers and industrial clients. The company leverages its long history and brand strength to maintain a competitive advantage. The website content and news updates indicate active innovation and market engagement. The company maintains a presence on major social media platforms and uses advanced marketing and tracking tools to optimize customer engagement. The lack of direct contact information on the main page suggests a preference for controlled communication channels, possibly via dedicated contact pages.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and a cookie consent mechanism that aligns with GDPR requirements. The use of multiple third-party analytics and marketing scripts introduces some risk, but no vulnerable libraries or exposed sensitive data were detected in the HTML content. The absence of explicit security policies or incident response contacts is a gap that could be addressed to enhance trust and readiness. Security headers are not explicitly visible and should be implemented to strengthen defenses against common web attacks. Overall, the site is secure but could improve transparency and technical security controls.

Recommendations

  1. Implement comprehensive HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance contact information availability on the website for better user support and trust.
  5. Consider verifying and publishing WHOIS data or clarifying domain registration details to reduce suspicion.

Notes

The website is built on TYPO3 CMS, a robust and scalable content management system. It uses modern JavaScript libraries and integrates multiple marketing and analytics services including Google Tag Manager, Google Analytics, Facebook Pixel, Hotjar, and LinkedIn Insight Tag. The site is mobile optimized with responsive design and good accessibility features. Performance is moderate, likely influenced by the number of external scripts and image assets. SEO is well addressed with proper meta tags, Open Graph data, and JSON-LD structured data. The site uses HTTPS exclusively, ensuring encrypted communication. Hosting provider details are not explicitly available from the content. Overall, the technical infrastructure supports a professional and user-friendly experience with room for performance optimization.
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.
