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

SwissCaution SA is a leading Swiss company specializing in rental guarantees without requiring tenants to block bank deposits. Positioned as the number one provider in Switzerland, it offers services for private tenants, businesses, and lessors, including provisional certificates and a 24/7 HomeAssistance service. The website is built on modern technologies such as Next.js and React, with integration of Google Tag Manager for analytics. Despite good content quality, SEO, and user experience, the site suffers from a critical security issue due to an invalid SSL certificate, which undermines trust and security. Privacy and legal compliance are well addressed with comprehensive privacy and terms of service pages. Social media presence and customer reviews enhance credibility.

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 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';…

  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

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

SwissCaution operates in the real estate sector, providing an alternative to traditional bank deposits for rental guarantees. Its business model focuses on insurance-like products that free tenants' capital while reassuring landlords and agencies. The company targets private individuals, commercial clients, and landlords, with a strong market position as the leading rental guarantee provider in Switzerland. The presence of loyalty discounts and youth offers indicates customer retention strategies. The company maintains partnerships, including a professional portal (pro.swisscaution.ch), and leverages social media for marketing. The website content and structure support a professional and trustworthy brand image.

Security posture

The website demonstrates moderate security maturity with proper security headers and CORS policies. However, the absence of a valid SSL certificate is a critical vulnerability that exposes users to risks and reduces trust. DNSSEC is not enabled, and CAA records are malformed, indicating gaps in domain security. The lack of OCSP stapling and session resumption further limits TLS performance and security. No explicit incident response or vulnerability disclosure policies are found. Privacy compliance is supported by detailed policies, but cookie consent mechanisms are missing. Overall, the security posture requires urgent improvement to meet industry standards and protect users effectively.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate immediately to secure all user interactions.
  2. Enable and configure HSTS with preload and includeSubDomains to enforce HTTPS.
  3. Correct malformed CAA DNS records and enable DNSSEC to strengthen domain security.
  4. Implement OCSP stapling and TLS session resumption to improve security and performance.
  5. Introduce a cookie consent mechanism to comply with privacy regulations and enhance user trust.
Technical notes

Notes

The website uses a modern tech stack centered on Next.js and React, indicating a contemporary and scalable architecture. The CMS appears to be WordPress, likely in a headless or hybrid configuration. Google Tag Manager is used for analytics and marketing tracking. Performance metrics are missing or zero, suggesting incomplete data or potential performance issues. Mobile optimization is good, and SEO practices are well implemented with proper meta tags and structured data. Accessibility is basic but present. The invalid SSL certificate is a major technical risk that must be addressed to avoid user trust issues and potential data interception.
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.
