StayFriends.ch is a Swiss online social networking platform focused on reconnecting former school friends, viewing class photos, and organizing reunions. It serves a niche educational social network market with over 1.3 million members. The platform offers a freemium business model targeting former students in Switzerland, providing region-specific school search and member directories. The website is professionally designed with consistent branding and clear navigation, supporting a good user experience for its target audience. Technically, the site uses modern JavaScript libraries such as jQuery and Bootstrap, integrates Google Tag Manager for analytics, and employs privacy management scripts to comply with GDPR. Security posture is solid with HTTPS enforced and secure form handling, though some security headers and explicit incident response contacts are missing. The WHOIS data aligns well with the business claims, indicating a trustworthy domain registration. Overall, the site demonstrates a mature digital presence with moderate advertising and tracking practices balanced by privacy compliance mechanisms.

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. 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

  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 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 company behind StayFriends.ch, klassenfreunde.ch GmbH, operates in the education sector providing a specialized social network for school alumni in Switzerland. Its competitive advantage lies in its large member base and localized school search features. Revenue likely derives from premium memberships and advertising partnerships, including Ströer Digital Group and Yieldlove. The platform is part of a broader ecosystem with partner sites in Germany, Austria, France, and Sweden, indicating a regional expansion strategy. The target customers are former students seeking to reconnect and organize reunions. The business shows signs of stability and moderate growth with a clear focus on privacy and compliance, which is critical in the European market.

Security posture

The website exhibits a good security maturity level with enforced HTTPS, secure form inputs, and GDPR-compliant privacy management. However, it lacks explicit security policies and incident response contact details, which are important for transparency and trust. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party ad and tracking scripts is balanced with user consent mechanisms, reducing privacy risks. To improve, the company should implement additional security headers and publish a vulnerability disclosure policy to enhance security culture and incident readiness.

Recommendations

  1. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to strengthen browser security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Review and minimize third-party tracking scripts to reduce privacy risks and improve user trust.
  5. Enhance mobile optimization and accessibility features to improve user experience across devices.

Technical notes

Notes

The website uses a custom CMS with modern front-end technologies including jQuery, jQuery UI, Bootstrap, and Font Awesome. Google Tag Manager is used for analytics and marketing tags. Privacy management scripts indicate GDPR compliance efforts. Performance is moderate with room for improvement in mobile responsiveness and accessibility. No CMS-specific platform like WordPress or Drupal was detected, suggesting a bespoke solution. Hosting provider details are not explicit. The site uses canonical URLs and meta tags for SEO, contributing to good search engine visibility. Technical risks are low but could be mitigated further by updating libraries and enhancing security headers.
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.
