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

5 findings rated critical or high. Fix these first.

  1. Network security

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

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • 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
    • 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

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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 · found on this site
  • 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

Syna holds a strong market position as a major Swiss trade union with a broad membership base and sector coverage. Its non-profit business model relies on membership fees and offers value through legal protection, education, and solidarity initiatives. The organization maintains an active partnership ecosystem including its unemployment fund and member portal. The website's multilingual support and detailed membership forms indicate a focus on accessibility and inclusivity. Testimonials and social media engagement enhance credibility and member trust. The absence of privacy protection in WHOIS data aligns with the organization's transparency. Growth indicators include active campaigns and digital engagement tools.

Security posture

The website demonstrates a solid security posture with mandatory HTTPS, encrypted form submissions, and cookie consent mechanisms. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not detected, representing an area for improvement. No vulnerabilities or exposed sensitive data were found in the HTML content. The use of third-party analytics and tracking scripts is balanced with privacy compliance. Incident response and security policy information are not publicly available, which could be enhanced to improve security culture and readiness.

Recommendations

  1. Implement and enforce security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and vulnerability disclosure page to enhance transparency and incident response readiness.
  3. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  4. Enhance visibility of contact channels for security incidents or abuse reports.
  5. Continue to maintain and update privacy and cookie policies to comply with evolving regulations.

Technical notes

Notes

The website is built on Joomla CMS with Yootheme templates and uses UIkit for UI components. It integrates jQuery and Flatpickr for enhanced user interactions, especially in forms. Analytics are handled via Matomo and Google Tag Manager, with Facebook Pixel for marketing. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured data (JSON-LD). Performance is moderate, likely due to rich media content and multiple scripts. There is no indication of outdated or vulnerable libraries. Hosting provider details are not explicitly found. The technical stack supports a professional and user-friendly experience but could benefit from further performance optimization and security hardening.
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.
