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

Sustainable Skies World Summit is a UK-based event organizer focused on addressing sustainability challenges in the aviation industry. The website promotes the 2026 summit scheduled for March 17-18, positioning itself as a leading UK event in sustainable aviation. The business model revolves around event hosting and industry networking, targeting aviation professionals and sustainability stakeholders. The site content is professionally presented with good SEO and structured data, reflecting a well-maintained digital presence for a newly founded organization in 2024. Technically, the website is built on WordPress with common technologies such as jQuery, Bootstrap, and WP Rocket for performance optimization. It integrates multiple analytics and marketing tools including Google Analytics, Microsoft Clarity, LinkedIn Insight Tag, and Cookiebot for cookie consent management. The site is mobile-optimized and uses HTTPS with a good SSL configuration, although no explicit security headers were detected in the provided data. From a security perspective, the site demonstrates good practices such as HTTPS enforcement, cookie consent with blocking mode, and bot protection via Google reCAPTCHA. However, it lacks published security policies, incident response contacts, and explicit privacy and terms of service pages, which are recommended for compliance and trust. No vulnerabilities or suspicious patterns were detected, and WHOIS data aligns with the business timeline, indicating legitimacy. Overall, the website presents a moderate to good security posture and digital maturity for a new event business. Strategic improvements in privacy documentation, security headers, and contact transparency would enhance trust and compliance. The risk level is moderate with no critical issues identified.

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.

Priority findings

6 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  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

The Sustainable Skies World Summit operates as a niche event organizer within the transportation sector, specifically targeting sustainable aviation. Its market positioning as a leading UK event suggests a competitive advantage in sustainability-focused aviation conferences. Revenue streams likely include event registrations, sponsorships, and partnerships. The target customer segments are aviation industry professionals, sustainability advocates, and corporate stakeholders interested in net zero and sustainable aviation solutions. The partnership ecosystem includes major analytics and marketing platforms but no direct business partners were identified from the domain data. Growth indicators include recent domain registration aligned with event launch and professional digital presence. Strategic observations highlight the importance of expanding contact transparency and compliance documentation to support business credibility and growth.

Security posture

The website exhibits a moderate security maturity level with HTTPS enabled and cookie consent mechanisms in place. The use of Google reCAPTCHA and multiple analytics tools indicates awareness of bot mitigation and user tracking. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No exposed sensitive data or vulnerable libraries were detected, and forms appear secured with reCAPTCHA. Compliance gaps include missing published privacy and terms of service pages and lack of incident response contact information. Data protection practices are partially visible through Cookiebot disclosures. Incident response readiness and security culture indicators are not evident from the content. Overall, the security posture is adequate for a small event website but can be improved with formal policies and enhanced technical controls.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages accessible from the website footer.
  2. Implement and disclose a formal security policy including incident response procedures and contact channels.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  4. Provide clear company contact information including emails and phone numbers to improve transparency and trust.
  5. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS using a modern tech stack including jQuery, Bootstrap, and WP Rocket for performance optimization. It integrates multiple third-party services such as Google Analytics, Microsoft Clarity, LinkedIn Insight Tag, and Cookiebot for analytics and compliance. The site uses HTTPS with a valid SSL certificate and is mobile-optimized with responsive design. Performance is moderate with deferred script loading and preconnect hints. Accessibility features are basic but present. SEO is well implemented with meta tags, Open Graph, and JSON-LD structured data. Technical risks include reliance on multiple third-party scripts which require monitoring for vulnerabilities. The hosting provider is not explicitly identified from the data. Overall, the technical infrastructure supports a professional event website with room for improvement in security hardening and accessibility.
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.
