Security score

56/100

Risk levelMedium

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

Tesla Batteries USA Corp. operates in the energy sector, specializing in consumer and industrial battery products. The company targets both consumer markets and industrial clients, positioning itself as a niche player in battery manufacturing. The website serves as a landing page with navigation to product sections and provides detailed contact information for company representatives, indicating a small but professional business presence. Technically, the site uses legacy JavaScript libraries such as jQuery 1.11.2 and Modernizr 2.6.2, with some modern plugins like Zoomslider. The site is moderately optimized for mobile and performance but lacks advanced SEO and accessibility features. Security posture is moderate; the site uses HTTPS (implied by domain but not explicitly confirmed), but no security headers are detected, and outdated libraries pose potential risks. Privacy compliance is low due to the absence of privacy and cookie policies. Overall, the site is functional and professional but would benefit from modernization and improved security and privacy practices.

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. 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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. 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

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 appears to be a small-sized entity founded in 2012, operating primarily in the energy and transportation sectors with a focus on battery products. The business model revolves around manufacturing and distributing batteries for consumer and industrial use. Contact details and physical address in the United States support legitimacy. The lack of social media presence and limited online content suggests a focused but possibly limited digital marketing strategy. No partnerships or subsidiaries are evident from the data. The company uses a Tesla-branded name, which may imply a strategic branding choice to leverage Tesla's market recognition, though no direct affiliation is confirmed.

Security posture

The website demonstrates a basic security posture with HTTPS usage (assumed but not explicitly verified), no visible security headers, and no forms that collect user data on the main page, reducing attack surface. However, the use of outdated JavaScript libraries like jQuery 1.11.2 introduces potential vulnerabilities. The absence of privacy and cookie policies indicates compliance gaps with GDPR and other privacy regulations. No incident response or vulnerability disclosure information is provided, which may impact trustworthiness. The domain registration is stable and consistent with the business age, with no privacy protection used, enhancing transparency. Recommendations include updating libraries, adding security headers, and implementing privacy policies.

Recommendations

  1. Upgrade all JavaScript libraries to current supported versions to mitigate known vulnerabilities.
  2. Implement comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance security posture.
  4. Enable DNSSEC for the domain to improve DNS security.
  5. Consider adding incident response and vulnerability disclosure information to demonstrate security maturity and transparency.

Technical notes

Notes

The website uses a combination of legacy and modern JavaScript libraries, including jQuery 1.11.2, Modernizr 2.6.2, and Zoomslider plugin. The site is structured with CSS and JavaScript assets loaded locally and from CDNs. No CMS or major frameworks are detected, suggesting a custom or static site build. Performance is moderate with some mobile optimization evident. SEO is basic with minimal meta description and no Open Graph or JSON-LD structured data present. Accessibility features are minimal. Hosting and registrar information indicate use of Gransy, s.r.o. as registrar and DNS provider, but no detailed hosting provider info is available. Overall, the technical infrastructure is functional but could benefit from modernization and enhanced SEO and accessibility practices.
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.
