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

4 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 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

SESAR Deployment Manager occupies a key position in the European air traffic management modernization ecosystem, acting as the deployment coordinator for SESAR solutions. Its business model is governmental/intergovernmental, focusing on coordination, project management, and stakeholder engagement rather than commercial activities. The organization targets aviation stakeholders across Europe, including service providers and regulators. The website content and structure indicate a medium-sized entity with strong ties to the SESAR Joint Undertaking, its parent organization. The absence of commercial advertising and the presence of official EU branding reinforce its authoritative market position. Growth indicators include active communication channels and up-to-date project information. The partnership ecosystem includes SESAR JU and other European aviation bodies, reflecting a collaborative operational model.

Security posture

The website exhibits a mature security posture with HTTPS enforced site-wide and multiple security headers implemented, such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options. No exposed sensitive data or vulnerable libraries were detected in the source code. Forms appear to be secure with no signs of insecure input handling. However, the absence of a publicly accessible security policy or vulnerability disclosure mechanism limits transparency and incident response readiness. GDPR compliance is evident through privacy and cookie policies with consent mechanisms. The site does not display any signs of malware, phishing, or other malicious activity. Overall, the security maturity is high but could be improved by adding explicit security governance documentation and incident response contacts.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and practices.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Add incident response contact information, such as a security@ or abuse@ email address.
  4. Regularly review and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance transparency by providing data retention policies and detailed privacy compliance statements.

Technical notes

Notes

The website is built on a modern static site generation framework, Gatsby, leveraging React for UI components. This architecture supports fast loading times, good SEO, and excellent mobile responsiveness. The use of OpenLayers suggests interactive geographic data visualization capabilities. The site employs standard web technologies including CSS modules and modern JavaScript. No CMS detected, indicating a controlled content deployment process. Performance is optimized with minimal external dependencies. Accessibility features are present but could be enhanced with ARIA roles and better keyboard navigation support. The technical infrastructure appears robust with no evident technical debt or legacy components. Hosting provider details are not explicitly disclosed but the site uses HTTPS with strong SSL configuration.
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.
