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

Heligo.aero is a small regional service provider specializing in helicopter flights including panoramic tours, gastronomic flights, initiation flights, transfers, and scenic tours such as the Mont Blanc tour. The website targets customers primarily in France and Switzerland, offering niche tourism and transportation services. The business appears to have been established around 2015, consistent with the domain registration date. Technically, the website is minimalistic with basic HTML content and limited technical sophistication. Hosting is provided by Infomaniak, a known Swiss hosting provider. The site lacks advanced technologies, analytics, or advertising scripts, and shows basic mobile optimization and accessibility. SEO is minimal but present through meta tags. From a security perspective, the site uses privacy-protected WHOIS registration, which is justified for a small business. However, no security headers, privacy policies, cookie consent mechanisms, or contact information are present, limiting trust and compliance posture. No WAF or blocking mechanisms were detected, and the site is accessible without restrictions. Overall, the website is functional but basic, with room for improvement in security, privacy compliance, and user engagement. Strategic enhancements in these areas would improve trustworthiness and regulatory compliance.

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 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

    • 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

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

Heligo operates in the transportation sector, focusing on helicopter flight services for tourism and transfers. Its market position is niche and regional, targeting French and Swiss customers interested in aerial experiences. The business model is service-based, generating revenue from flight bookings. The absence of detailed business information and contact data limits transparency. The company benefits from privacy protection for domain registration, which is common for small businesses. Growth potential exists through enhanced digital presence and customer engagement. No partnerships or subsidiaries were identified from the website content. The company relies on direct website traffic and possibly offline channels for customer acquisition. The lack of analytics and marketing tools suggests limited digital marketing efforts. Improving online visibility and adding trust signals could enhance competitive advantage.

Security posture

The current security posture is basic with significant gaps. The website lacks essential security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security. DNSSEC is not enabled, which could improve domain security. No privacy or cookie policies are present, indicating non-compliance with GDPR requirements. No incident response or security contact information is provided, reducing transparency and readiness for security events. No forms or input fields are present, minimizing attack surface but also limiting user interaction. The use of privacy-protected WHOIS is appropriate but does not compensate for missing security best practices. Recommendations include implementing security headers, enabling DNSSEC, publishing privacy and cookie policies, and adding contact channels for security incidents.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  4. Add clear contact information including email and phone for customer support and incident response.
  5. Improve mobile optimization and accessibility to enhance user experience and SEO.

Technical notes

Notes

The website is built with basic HTML and minimal styling, lacking modern frameworks or CMS detection. Hosting is provided by Infomaniak, a reputable Swiss hosting provider. The site does not use analytics, advertising, or tracking scripts, indicating a low digital footprint. Performance is moderate given the minimal content. SEO is basic with meta description and keywords present but no structured data or Open Graph tags. Accessibility and mobile responsiveness are basic but could be improved. The absence of forms or interactive elements reduces complexity but also limits user engagement.
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.
