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. 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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';…

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

Propelair operates in the cleantech sector focusing on energy and water efficiency for commercial facilities. Their business model is B2B, targeting facility managers and organizations aiming to reduce operational costs and environmental impact. The company leverages IoT technology to differentiate its offerings, providing real-time monitoring and management capabilities. Their certifications and accreditations position them as a trusted provider in sustainability-focused markets. The website content and structure support lead generation and customer engagement through detailed product information, case studies, and contact forms. Social media presence on LinkedIn, Facebook, and YouTube supports brand awareness and customer education. The company appears to be medium-sized with a long operational history since 2001, indicating stability and market experience.

Security posture

The website employs HTTPS with a valid SSL certificate, ensuring encrypted communications. Domain registration includes clientTransferProhibited and clientUpdateProhibited statuses, reducing risk of unauthorized domain changes. Cookie consent is implemented with GDPR compliance, including detailed cookie categories and user preferences. However, no explicit security policy or incident response information is published, and DNSSEC is not enabled, which could be improved to enhance DNS security. No vulnerable libraries or exposed sensitive data were detected in the HTML content. The use of popular and maintained plugins like Gravity Forms and WooCommerce suggests a maintained platform, but security headers are not explicitly identified and should be audited. Overall, the security posture is good but could benefit from additional hardening and transparency.

Recommendations

  1. Enable DNSSEC to improve domain name system security and prevent DNS spoofing.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a dedicated security policy page and provide incident response contact information to improve transparency and trust.
  4. Consider adding a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Regularly audit third-party plugins and scripts for vulnerabilities and keep them updated.

Technical notes

Notes

The website is built on WordPress CMS with WooCommerce for e-commerce capabilities and Gravity Forms for data collection. It uses modern JavaScript libraries such as Swiper.js for sliders and jQuery for DOM manipulation. SEO is enhanced via Yoast SEO plugin with proper meta tags and structured data (JSON-LD) for organization and webpage schema. The site loads external resources from trusted CDNs like jsdelivr.net and Google Tag Manager for analytics. Performance is moderate with responsive design and mobile optimization evident. Accessibility features such as skip links and ARIA labels are present, supporting usability. The technical stack is mature and well-integrated, though some improvements in security headers and DNS configuration could enhance robustness.
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.
