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

No critical or high findings. These medium findings are worth fixing next.

  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.

    • Medium

      Missing X-XSS-Protection header

      Legacy XSS protection (deprecated but still recommended)

      What to do: Add "X-XSS-Protection: 1; mode=block"

    • Medium

      Missing Permissions-Policy header

      Controls browser features and APIs

      What to do: Implement a Permissions-Policy to restrict feature access

      • OWASP Secure Headers: OWASP Secure Headers Project recommends Permissions-Policy: accelerometer=(), autoplay=(), camera=(), cross-origin-isolated=(),…
  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Medium

      Privacy policy may not be GDPR compliant

      Privacy policy lacks explicit GDPR compliance elements

      What to do: Update privacy policy to explicitly address GDPR requirements and user rights

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Medium

      DNSSEC Not Enabled

      DNSSEC is not configured for this domain

      What to do: Enable DNSSEC to prevent DNS spoofing attacks

      • CAPEC-142
      • RFC 4033

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 operates in the finance sector, focusing on audit, tax, legal, and consulting services. Its business model revolves around professional advisory services targeting medium to large enterprises and organizations in the Czech Republic. The firm leverages a strong brand presence and a large expert workforce. The website reflects a mature digital presence with integrated marketing and analytics tools, indicating a focus on client acquisition and engagement. No direct contact information or detailed corporate data is exposed on the site, which may be intentional for privacy. The absence of WHOIS data limits external verification but does not detract from the professional presentation. The company likely benefits from partnerships with major analytics and marketing platforms to optimize outreach.

Security posture

The website enforces HTTPS and uses a reputable cookie consent management system (Cookiebot), supporting GDPR compliance. Tracking technologies include Google Analytics, Microsoft Application Insights, Meta Pixel, and Leady, which collect user data with consent. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the site lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which could enhance protection against common web attacks. There is no visible security.txt or vulnerability disclosure policy, which are best practices for transparency and incident management. The absence of contact channels for security incidents reduces readiness perception. Overall, the security posture is good but could be improved with additional headers and published policies.

Recommendations

  1. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a security policy and incident response plan accessible from the website.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve transparency.
  4. Provide clear contact information for security incidents and data protection inquiries.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance.

Technical notes

Notes

The website uses Kentico CMS, Google Tag Manager, Cookiebot, Microsoft Application Insights, and Meta Pixel, indicating a modern and integrated technology stack. Fonts are loaded from Google Fonts and cdnfonts.com with preconnect and preload optimizations. The site is mobile responsive with CSS media queries and uses SVG and PNG icons. Performance is moderate with asynchronous loading of analytics scripts. Accessibility is basic with some ARIA roles and language attributes. SEO is supported by meta tags, canonical links, and hreflang tags for multilingual support. Hosting provider is not explicitly identified. The site could benefit from enhanced accessibility features and additional performance optimizations.
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.
