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. 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.

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

      What to do: Implement MTA-STS to prevent downgrade attacks

  4. 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 as a large enterprise in the finance sector, targeting corporate clients and business professionals worldwide. Its business model centers on providing comprehensive accounting and advisory services through a global network of member firms, as evidenced by multiple regional domains linked from the main site. The company demonstrates strong market positioning with a focus on privacy and regulatory compliance, leveraging marketing tools like Marketo and analytics platforms to optimize client engagement. The absence of public WHOIS data is consistent with privacy protection practices common among large professional firms. The partnership ecosystem is robust, with multiple regional subsidiaries clearly identified.

Security posture

The website exhibits a solid security foundation with HTTPS and cookie consent mechanisms that respect user privacy. The presence of anti-CSRF cookies and telemetry tools like Microsoft Application Insights shows attention to secure data handling. However, the lack of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. Incident response contact is provided via a legal email, but a dedicated security policy or vulnerability disclosure page is missing, which could enhance transparency and readiness.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen browser security.
  2. Publish a dedicated security policy and vulnerability disclosure page (security.txt) to improve transparency and incident response readiness.
  3. Regularly audit third-party scripts and libraries to ensure no vulnerable components are included.
  4. Enhance SEO metadata with descriptive titles and descriptions to improve search engine visibility.
  5. Consider adding explicit contact phone numbers and physical addresses to improve business credibility and user trust.

Technical notes

Notes

The website uses a modern tech stack including Kentico CMS, Google Tag Manager, Cookiebot for GDPR-compliant cookie management, and Microsoft Application Insights for telemetry. Fonts are loaded from Google Fonts and cdnfonts.com, and content delivery is optimized with multiple cookies for load balancing and session management. Performance is moderate with preloading of fonts and CSS. Accessibility features are present, including ARIA roles and keyboard navigable consent dialogs. SEO optimization is basic with canonical links but lacks meta description content. The site is mobile optimized and uses HTTPS exclusively, indicating a secure and user-friendly technical infrastructure.
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.
