Medium risk. 9 critical or high findings in Email security, Security headers and 3 other checks.

Security score

50/100

Risk levelMedium

0–100, higher is better. How it is calculated

VARTA AG is a well-established European leader in battery technology and energy storage solutions, with a history dating back to 1887. The company operates multiple divisions including Consumer Batteries, Micro Batteries, and Lithium-Ion technologies, with a significant automotive battery division owned by Clarios LLC. The website reflects a professional corporate presence with detailed business and contact information, targeting both consumers and industrial clients. Technically, the site uses TYPO3 CMS and integrates Matomo analytics for privacy-conscious tracking, alongside Google reCAPTCHA for form security. Security posture is generally strong with HTTPS enforced, though the absence of security headers and privacy policies indicates room for improvement. The missing WHOIS data is a notable anomaly but does not detract significantly from the overall legitimacy given the detailed corporate disclosures on the site.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 X-Frame-Options header

      Prevents clickjacking attacks

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

  3. GDPR outside view

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

    • 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

    • 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

    • 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

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

The company holds a strong market position as a European technology leader in battery manufacturing and research. Its business model focuses on innovation and production across multiple battery segments, serving diverse markets including automotive and consumer electronics. The presence of major shareholders like Montana Tech Components AG and Porsche AG underscores financial stability and strategic partnerships. The website links to subsidiary and partner domains, indicating a structured corporate ecosystem. Growth potential is supported by technological leadership and diversified product lines. However, the lack of visible privacy and security policies may impact customer trust in regulated markets.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS and use of reCAPTCHA to protect forms. The integration of Matomo analytics suggests a focus on privacy-friendly data collection. However, the absence of explicit security headers such as Content-Security-Policy and missing published privacy and cookie policies are gaps that could expose the site to certain risks and compliance issues. No vulnerabilities or exposed sensitive data were detected in the provided content. Incident response and vulnerability disclosure information are not present, which could hinder rapid mitigation of security incidents. Overall, the security maturity is adequate but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a dedicated security or incident response page with contact information for vulnerability reporting.
  4. Conduct a WHOIS record audit to ensure domain registration transparency and consistency with corporate identity.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and scalable content management system suitable for enterprise use. The use of Matomo analytics indicates a preference for privacy-respecting tracking solutions. Google reCAPTCHA is employed to secure forms, although no active forms were detected on the main page. The site demonstrates good mobile optimization and SEO practices with proper meta tags and structured data (JSON-LD). Performance is moderate, with no critical issues detected. The absence of security headers and incomplete privacy documentation represent technical debt and compliance risks. Hosting provider details are not disclosed, limiting full infrastructure assessment.
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.
