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

Clarios, LLC. is a global leader in advanced battery technologies, manufacturing over 150 million advanced low-voltage batteries annually for a wide range of vehicles including automotive, commercial, powersports, and leisure sectors. The company offers a diverse portfolio of products such as AGM, lithium-ion, supercapacitors, and sodium-ion batteries, alongside connected services leveraging AI-driven insights. Their market position is strong with a global footprint serving over 100 countries and multiple well-known subsidiary brands. The website reflects a mature digital presence with professional design, clear navigation, and comprehensive corporate content. Technically, the website is built on the Sitefinity CMS platform and integrates modern marketing and analytics tools including Google Tag Manager, Hotjar, LinkedIn Insight, and Criteo for advertising and user behavior tracking. The site is mobile-optimized, accessible, and SEO-friendly, with a moderate performance profile. Security best practices are observed with HTTPS enforcement, security headers, and a consent management platform for privacy compliance. Security posture is solid with no visible vulnerabilities or exposed sensitive data. However, the absence of a public vulnerability disclosure or security.txt file and explicit incident response contacts suggests room for improvement in transparency and incident readiness. Privacy compliance is well addressed with clear privacy and cookie policies and GDPR compliance indicators. Overall, the website and business demonstrate high professionalism and trustworthiness. The only notable concern is the lack of WHOIS data for the domain, which may be due to privacy protection or registrar issues but does not detract significantly from the legitimacy of the business. Strategic recommendations include publishing a vulnerability disclosure policy, enhancing incident response transparency, and disclosing any security certifications to further strengthen trust.

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. 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

    • 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

  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

Clarios operates in the energy and transportation sectors, focusing on advanced battery manufacturing and energy storage solutions. Their business model centers on supplying OEMs and aftermarket customers globally with innovative battery technologies and integrated systems. The company’s competitive advantage lies in its extensive product portfolio, global brand presence, and commitment to sustainability and innovation. Revenue streams likely include product sales, connected services, and licensing of technology. Target customers include automotive manufacturers, commercial vehicle operators, and leisure vehicle users. Growth indicators include recent product expansions and partnerships showcased in press releases. The company maintains a strong partnership ecosystem with multiple subsidiary brands and compliance frameworks, positioning it well for future market demands.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented. Use of a consent management platform and published policies such as whistleblower and conflict minerals policies indicate a strong compliance culture. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of a public vulnerability disclosure program and explicit incident response contact emails limits transparency. Compliance with GDPR is evident, but additional certifications or security frameworks are not explicitly stated. Overall, the security maturity is good with opportunities to enhance incident response readiness and disclosure practices.

Recommendations

  1. Publish a publicly accessible vulnerability disclosure or security.txt file to encourage responsible reporting.
  2. Provide explicit incident response contact information such as security@ or abuse@ email addresses.
  3. Disclose any security certifications or compliance frameworks to enhance trust and transparency.
  4. Maintain and regularly update privacy and cookie policies to ensure ongoing GDPR compliance.
  5. Enhance WHOIS data transparency if possible to improve domain registration trustworthiness.

Technical notes

Notes

The website is built on the Sitefinity CMS platform, leveraging modern JavaScript libraries and marketing technologies such as Google Tag Manager, Hotjar, LinkedIn Insight, and Criteo. The site is mobile-optimized, accessible, and SEO-friendly with proper meta tags and Open Graph data. Performance is moderate, with asynchronous loading of tracking scripts to minimize impact. The technical infrastructure supports a professional corporate presence with integrated analytics and consent management. Opportunities exist to improve hosting transparency and implement a security.txt file for vulnerability disclosures.
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.
