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

The business operates in the weather information sector, targeting residents and visitors in Switzerland who require timely severe weather warnings. Its subscription model generates revenue through premium alert packages with clear pricing tiers. The company benefits from partnerships with similar weather services across Europe, enhancing its market position. The website's content quality and navigation support user engagement, while GDPR compliance and cookie consent mechanisms demonstrate regulatory adherence. However, the absence of direct contact emails or phone numbers may limit immediate customer support accessibility. The platform's integration of advertising and analytics tools suggests a balanced approach to monetization and user data collection.

Security posture

The website exhibits a mature security posture with HTTPS enabled and multiple security headers implemented, reducing common web vulnerabilities. The use of a consent management platform aligns with privacy regulations, and login forms are secured with password inputs. No exposed sensitive data or vulnerable libraries were detected in the provided content. However, the lack of a published security policy, incident response information, or vulnerability disclosure program represents a gap in transparency and preparedness. Enhancing these areas would improve trust and readiness for potential security incidents.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and incident response procedures.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Enhance accessibility features to improve usability for all users, including those with disabilities.
  4. Provide clear company contact emails and phone numbers for customer and security inquiries.
  5. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern tech stack including JavaScript, OpenLayers for interactive maps, and Handlebars.js for templating. It employs Bootstrap for responsive design and integrates Google Analytics for traffic analysis. Consentmanager.net is used for cookie consent management, ensuring GDPR compliance. The site loads external resources efficiently and appears optimized for desktop and mobile devices. Performance is moderate, with room for improvement in accessibility and SEO. Hosting details are not explicitly identified, but the presence of security headers and HTTPS indicates a professionally managed infrastructure. Overall, the technical implementation supports the business goals effectively with opportunities for further modernization.
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.
