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

6 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 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

  3. 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

Skyguide operates in the transportation sector, specifically air navigation services, serving a broad range of aviation stakeholders including airlines, military, and drone operators. The company benefits from a strong brand and certifications such as the CANSO GreenATM level 3 accreditation, highlighting its commitment to sustainability. Revenue streams likely include service fees for air traffic management, commercial services, and training via its academy. The company maintains active engagement through media releases and social channels, indicating a transparent and growth-oriented approach. No parent or subsidiary companies were identified, suggesting independent operation. The website's comprehensive content and clear contact information enhance business credibility and customer trust.

Security posture

The website exhibits a mature security posture with mandatory HTTPS, cookie consent banners, and no visible exposure of sensitive data. Use of modern JavaScript frameworks and third-party analytics is balanced with privacy compliance. However, the absence of a published security policy or incident response contact limits transparency in security governance. Security headers are not explicitly visible in the HTML but may be configured at the server level. No vulnerabilities or suspicious domains were detected. Recommendations include publishing a security policy, incident response contacts, and implementing explicit security headers to further strengthen security maturity.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Maintain transparency on data retention policies related to analytics and tracking.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve user trust.

Technical notes

Notes

The website is built on a modern tech stack featuring Nuxt.js and Vue.js frameworks, with WordPress likely used as a CMS backend. It integrates multiple analytics and marketing tools including Google Tag Manager, Facebook Pixel, TikTok Pixel, and Adform tracking. The site is optimized for mobile devices and accessibility, with good SEO practices evident from meta tags and structured content. Performance is moderate, with asynchronous loading of scripts to improve user experience. No technical debt or deprecated libraries were detected. Hosting provider details were not explicitly found. Overall, the technical infrastructure supports a professional and scalable digital presence.
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.
