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

Verein ARC is a Swiss non-profit educational institute focused on providing continuing education and training for employees, particularly those affiliated with labor unions such as Travail.Suisse, Syna, transfair, SCIV, and swissPersona. The organization operates under the umbrella of Travail.Suisse and offers courses aimed at enhancing skills in customer handling, member engagement, and organizational effectiveness. The website reflects a professional and consistent brand identity with clear messaging targeted at employees and union members in Switzerland. Technically, the website is built on Drupal 10 with Bootstrap and FontAwesome, ensuring a modern and responsive user experience. The site is well-optimized for mobile devices and accessibility, with good SEO practices and social media integration. Performance is moderate, with no significant technical debt or errors observed. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms compliant with GDPR. However, it lacks explicit security headers and a published incident response or vulnerability disclosure policy. No vulnerabilities or exposed sensitive data were detected. The WHOIS data aligns well with the website's organizational claims, indicating legitimacy and transparency. Overall, the website presents a low-risk profile with strong business credibility and good privacy compliance. Strategic improvements in security headers and incident response transparency would further enhance its security posture.

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 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 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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 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

The organization occupies a niche position within the Swiss labor movement, leveraging its affiliation with Travail.Suisse and member unions to provide targeted educational services. Its business model is non-profit, focusing on employee development and union member training. Revenue streams likely come from course fees and union funding. The target audience includes union members and employees seeking professional development. The partnership ecosystem includes Travail.Suisse Formation and eduQua certification, enhancing credibility. Growth indicators include a regularly updated course catalog and active social media presence. The organization's operations emphasize education, labor rights, and member engagement within Switzerland.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and GDPR-compliant cookie consent. Absence of security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No incident response contacts or vulnerability disclosure policies are published, which could hinder rapid response to security incidents. No signs of vulnerabilities or data leaks were found. The security culture appears cautious but could benefit from enhanced transparency and formalized policies. Overall, the site is secure for its purpose but should adopt additional best practices to strengthen defenses and compliance.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web attacks.
  2. Publish an incident response contact or security email address to facilitate reporting and handling of security issues.
  3. Develop and publish a vulnerability disclosure policy or security.txt file to encourage responsible vulnerability reporting.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.
  5. Enhance website performance optimization to improve loading speed and user experience.

Technical notes

Notes

The website is built on a modern Drupal 10 CMS platform, utilizing Bootstrap for responsive design and FontAwesome for iconography. The site includes social sharing via Sharriff and is optimized for mobile devices with good accessibility features. Meta tags and Open Graph data are properly configured for SEO and social media sharing. No analytics or tracking scripts were detected, indicating a privacy-conscious approach. Performance is moderate, with potential for improvement through caching and asset optimization. The technical infrastructure supports the business goals effectively with room for modernization in security headers and incident response capabilities.
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.
