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 holds a significant market position as a specialized OEM supplier in the aviation sector, serving a niche but critical industry. Their business model revolves around manufacturing and supplying aircraft parts and accessories, likely generating revenue through OEM contracts and aftermarket sales. The presence of official social media and structured data indicates an established digital footprint. However, the absence of detailed contact information and compliance policies on the site suggests potential areas for operational transparency enhancement. No evidence of partnerships or subsidiaries was found in the provided data, indicating a focused business scope.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and use of Google site verification. However, it lacks visible security headers and formal security policies, which are important for compliance and trust. No incident response or vulnerability disclosure mechanisms are publicly available, which could hinder rapid response to security events. The use of modern analytics and tracking scripts implies moderate user tracking, but privacy compliance is weak due to missing policies. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Overall, the security maturity is moderate but could be improved by adding formal policies and security headers.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement and display a terms of service and security policy page.
  3. Add incident response contact information and a vulnerability disclosure policy or security.txt file.
  4. Enhance HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Ensure all forms include security measures like CSRF tokens and input validation to prevent abuse.

Technical notes

Notes

The website is built on WordPress CMS using Foundation CSS framework and integrates Google Tag Manager and Google Analytics for tracking. It uses Typekit for fonts and Gravity Forms for form management, indicating a modern and extensible technical stack. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by meta tags and structured data in JSON-LD format, enhancing search engine visibility. Hosting provider details are not explicit, but the site uses HTTPS with a valid SSL certificate. There is no evidence of technical debt or deprecated technologies in the provided content. Opportunities exist to improve accessibility and security headers for a more robust technical posture.
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.
