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

Preisvergleich.ch is a well-established Swiss price comparison platform operated by Preisvergleich Europe GmbH. It offers users comprehensive product listings, buying guides, and test reports to facilitate informed purchasing decisions. The platform targets Swiss consumers seeking competitive prices and trustworthy product information. Technically, the site employs modern JavaScript libraries such as jQuery and Owl Carousel, integrates Google Tag Manager and Analytics for tracking, and uses JSON-LD structured data to enhance SEO and search capabilities. The website is mobile-optimized with good navigation and content quality. Security-wise, the site enforces HTTPS and avoids exposing sensitive data, but lacks visible security headers and formal security policies. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism detected. Overall, the site is professional and trustworthy but could improve in privacy and security transparency.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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
  • 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 business operates in the e-commerce sector as an affiliate price comparison service, leveraging partnerships with numerous verified online shops primarily in Switzerland, but also including international sellers shipping to Switzerland. Its competitive advantage lies in comprehensive product coverage, expert buying advice, and integration with partner sites in Austria and Germany. The business model relies on affiliate commissions and advertising. The presence of a YouTube channel and detailed content indicates a focus on content marketing and consumer engagement. The parent company Preisvergleich Europe GmbH provides corporate governance and legal framework. Growth potential exists through expanding product categories and enhancing privacy compliance.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible sensitive data leaks. However, it lacks advanced security headers such as Content-Security-Policy and Strict-Transport-Security, which could mitigate common web attacks. There is no public incident response or vulnerability disclosure information, which limits transparency and readiness perception. The absence of a cookie consent banner is a compliance gap under GDPR and Swiss data protection laws. No vulnerable libraries or obvious security flaws were detected in the HTML content. Overall, the security posture is adequate but could be significantly improved by adopting best practices and publishing security policies.

Recommendations

  1. Implement a visible cookie consent banner to comply with GDPR and Swiss regulations.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Include terms of service to clarify user rights and legal conditions.

Technical notes

Notes

The website uses a modern but somewhat traditional tech stack centered on jQuery and Owl Carousel for UI components. Google Tag Manager and Analytics are integrated for tracking user behavior. The site uses JSON-LD structured data to improve search engine understanding and supports search actions. Performance is moderate with preloading of fonts and CSS, but no explicit advanced performance optimizations detected. Mobile optimization is good with responsive design and accessible navigation. Accessibility features are basic, with some ARIA labels and semantic HTML. The site is hosted on a domain consistent with the business and uses HTTPS with a valid certificate. There is room for modernization by adopting newer JavaScript frameworks and improving accessibility and 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.
