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

Sihlcity is a prominent urban entertainment and shopping center located in Zurich, Switzerland. The website presents a well-structured digital presence with a focus on retail, dining, and entertainment services targeting the general public and visitors in Zurich. The business model revolves around providing a comprehensive shopping and leisure experience in a large-scale urban environment. The site is professionally designed with consistent branding and good content quality, supporting its market position as a major retail hub. Technically, the website leverages modern JavaScript frameworks, notably Vue.js, and is managed via Magnolia CMS. It integrates Cookiebot for cookie consent management and Google Tag Manager for analytics, indicating a moderate level of digital maturity. The site is mobile-optimized and performs moderately well, with good SEO practices observed. From a security perspective, the website enforces HTTPS and implements cookie consent mechanisms, but lacks explicit security headers and published security policies such as incident response or vulnerability disclosure. No critical vulnerabilities or suspicious content were detected. Privacy compliance is basic, with no visible privacy policy or terms of service on the homepage, which is a notable gap. Overall, the website is trustworthy and professional, with a solid business credibility score. Strategic improvements in privacy policy publication, security header implementation, and incident response transparency would enhance the security posture and compliance standing.

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

3 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. 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

Sihlcity operates as a large retail and entertainment center in Zurich, targeting a broad consumer base including local residents and tourists. Its competitive advantage lies in its urban location and comprehensive service offering, combining shopping, dining, and entertainment under one roof. The business model is based on leasing retail spaces and hosting events to attract foot traffic. The website reflects a mature digital presence with integration of marketing and analytics tools. The absence of detailed business registration or VAT information on the site suggests a focus on consumer-facing content rather than corporate transparency online. Partnerships or subsidiaries are not explicitly mentioned, indicating a standalone operation or a focus on direct consumer engagement.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and cookie consent managed via Cookiebot. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security robustness. No security.txt or vulnerability disclosure mechanisms are present, limiting transparency and readiness for incident response. The absence of published security policies or contact channels for security incidents indicates potential gaps in compliance with GDPR and NIS2 requirements. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security posture is adequate but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Implement and publish a security policy including incident response procedures and contact channels.
  3. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to HTTP responses.
  4. Consider publishing a security.txt file to facilitate vulnerability disclosure and improve transparency.
  5. Enhance privacy compliance by detailing data retention policies and user rights in line with GDPR.

Technical notes

Notes

The website is built using modern web technologies including Vue.js and Magnolia CMS, indicating a contemporary technical infrastructure. It uses Cookiebot for cookie management and Google Tag Manager for analytics, reflecting integration of standard marketing and compliance tools. The site is mobile-optimized with responsive design and good SEO metadata including JSON-LD structured data for the shopping center. Performance is moderate, with multiple CSS and JS assets loaded asynchronously. No deprecated or vulnerable libraries were detected in the HTML content. Opportunities exist to improve accessibility features and implement additional security headers to reduce technical risks.
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.
