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

2 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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

BDO Schweiz operates in the finance sector with a focus on auditing, tax, fiduciary, and consulting services. The business model revolves around providing specialized professional services to Swiss companies and individuals. The company leverages a strong partnership with the global BDO network, enhancing its market reach and credibility. Revenue streams likely include consulting fees, auditing contracts, tax advisory, and digital service subscriptions. The target customers are SMEs, large companies, and private clients in Switzerland. The website content and event listings indicate active engagement with clients and prospects, supporting growth and brand loyalty. The company maintains a consistent brand image and offers a wide range of services, positioning itself as a comprehensive service provider in the Swiss finance market.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and multiple security headers implemented, including HSTS, CSP, and X-Frame-Options. Cookies related to security such as CSRF tokens are present. The site uses a cookie consent mechanism to comply with privacy regulations, reducing risk of unauthorized data collection. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a public security policy or incident response contact information is a gap that could affect transparency and trust. Overall, the security measures are strong for a corporate website, but improvements in disclosure and incident handling communication are recommended.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement and publicly expose a security.txt file for vulnerability disclosure and incident reporting.
  3. Add explicit contact channels for security incidents such as security@ or abuse@ email addresses.
  4. Regularly review and update third-party scripts and tracking tools to minimize security risks.
  5. Enhance transparency on data retention and processing practices to strengthen privacy compliance.

Technical notes

Notes

The website uses a modern technology stack including React for frontend rendering and Kentico CMS for content management. It integrates multiple analytics and marketing tools such as Google Tag Manager, Microsoft Application Insights, Facebook Pixel, and Cookiebot for consent management. The site is mobile optimized with responsive design and preloads fonts and CSS for performance. Security headers and HTTPS are properly configured. Performance is moderate, likely due to multiple external scripts and rich media content. The site architecture supports multilingual content and has clear navigation structures. Opportunities exist to optimize script loading and reduce third-party dependencies to improve load times and reduce attack surface.
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.
