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. 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. 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

Walder Wyss operates in the finance/legal sector with a business model focused on providing high-value legal services to corporate clients. Their market positioning as a leading Swiss law firm is supported by awards and a large team of experts. The firm leverages a network of partner domains specialized in niche legal areas, enhancing their service portfolio. Revenue streams likely derive from legal advisory, tax consulting, and notary services. The website's content and structure indicate a focus on client engagement, recruitment, and thought leadership. The partnership ecosystem is visible through multiple related domains, indicating strategic alliances. Growth indicators include recent news about promotions and rankings. The firm maintains a strong brand consistency and professional online presence.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and domain transfer protection status. However, the absence of DNSSEC and lack of visible security headers such as Content-Security-Policy or X-Frame-Options suggest room for enhancement. The cookie consent mechanism is implemented properly, supporting privacy compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The lack of a published security policy or incident response contact channels is a gap in transparency and readiness. Overall, the security posture is solid but could be improved by adopting additional best practices and publishing relevant security documentation.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish a formal security policy and incident response contact information on the website.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  4. Consider publishing a vulnerability disclosure policy and security.txt file to encourage responsible reporting of security issues.
  5. Regularly review and update cookie and privacy policies to maintain compliance with evolving regulations and best practices.

Technical notes

Notes

The website uses modern web technologies including JavaScript, CSS, and HTML5 with asynchronous loading of Google Tag Manager and Google Analytics scripts. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with no major issues detected in the HTML content. The domain is registered with a reputable registrar and uses stable DNS servers. The website does not appear to use a common CMS, suggesting a custom or proprietary platform. Technical debt is minimal based on the provided content, but enabling DNSSEC and adding security headers would modernize the security infrastructure further. The site’s SEO is supported by proper meta tags, Open Graph, and JSON-LD structured data enhancing search engine visibility.
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.
