Risk levelMedium

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

WhirlWind Propellers is a specialized manufacturer and service provider of propellers for airboats, aircraft, UAVs, and wind tunnel testing. The company has a niche market position and is now integrated as part of Hartzell Propeller, a larger parent company based in Piqua, Ohio. The website reflects a small business with a focused product line and clear contact channels. Technically, the website uses established but somewhat dated technologies such as Bootstrap 3 and jQuery, hosted behind Cloudflare DNS services. The site is accessible, mobile-optimized, and provides a good user experience with clear navigation and relevant content. Security posture is moderate; HTTPS is implied but no explicit security headers or DNSSEC are enabled, and privacy compliance is lacking due to absence of privacy and cookie policies. Overall, the domain is legitimate with a long registration history consistent with the business claims.

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

8 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 operates in the transportation sector, specifically aviation and airboat propeller manufacturing. Its business model centers on manufacturing and servicing specialized propeller products, targeting aviation professionals, airboat operators, and UAV manufacturers. The integration with Hartzell Propeller suggests strategic consolidation and access to broader resources. The website's limited marketing and analytics footprint indicates a focus on direct customer engagement rather than broad digital marketing. The presence of social media channels on Facebook and YouTube supports brand awareness and customer engagement. The company appears stable with a long domain age and consistent registration data, reinforcing credibility.

Security posture

The website demonstrates a basic security posture with HTTPS likely enabled via Cloudflare, but lacks visible security headers such as CSP, HSTS, or X-Frame-Options. No vulnerability disclosure or incident response information is provided, and no security certifications are mentioned. The absence of DNSSEC reduces domain security resilience. Contact information is openly provided but no dedicated security contact channels exist. The site does not appear to use tracking or analytics scripts that could introduce privacy risks. Overall, the security maturity is moderate but could be improved by implementing standard security headers, enabling DNSSEC, and publishing privacy and security policies.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Enable DNSSEC on the domain to enhance DNS security.
  3. Publish comprehensive privacy and cookie policies to improve GDPR and privacy compliance.
  4. Add a vulnerability disclosure policy or security contact email to support incident response readiness.
  5. Regularly audit and update third-party libraries and scripts to mitigate vulnerabilities.

Technical notes

Notes

The website is built on Bootstrap 3 with jQuery and Font Awesome 4.2, indicating a somewhat dated but stable technology stack. Hosting is managed via Cloudflare DNS, which may provide CDN and security benefits. The site is mobile responsive and uses Google Fonts for typography. Performance is moderate with no explicit indicators of slow loading. SEO optimization is basic with minimal meta description content. Accessibility features are basic but present. No CMS is detected, suggesting a custom or static site. The contact form collects standard user data with client-side validation but no visible CAPTCHA or anti-spam measures. Overall, the technical infrastructure is functional but could benefit from modernization and enhanced security controls.
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.
