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.

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 diverse sectors including financial services, healthcare, natural resources & energy, private equity, public sector, real estate & construction, technology, media & entertainment, telecommunications, and transport. The company targets businesses and organizations requiring professional advisory and compliance services globally. The business model is based on delivering specialized consulting, audit, tax, and outsourcing services through a large international network. The website content and structure support clear navigation and service discovery, reinforcing BDO's market position as a comprehensive and reliable professional services provider.

Security posture

The website employs HTTPS with a valid SSL certificate supporting TLS 1.2 and 1.3 protocols, and OCSP stapling is enabled and successful. SPF and DMARC DNS records are properly configured with a strict reject policy, reducing email spoofing risks. No vulnerable SSL/TLS ciphers or protocols were detected, and no subdomain takeover vulnerabilities exist. However, HTTP Strict Transport Security (HSTS) is not enabled, which is recommended to prevent protocol downgrade attacks. No explicit security or incident response policies were found on the site. The cookie consent mechanism is robust, and no exposed sensitive data or vulnerable libraries were identified, indicating a mature security posture.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to enhance HTTPS enforcement.
  2. Implement CAA DNS records to restrict certificate authorities authorized to issue certificates for the domain.
  3. Improve certificate transparency compliance to increase trust and detect mis-issuance.
  4. Optimize website performance by reducing load time and resource count to improve user experience.
  5. Publish explicit security and incident response policies to enhance transparency and trust.
Technical notes

Notes

The website uses a modern technology stack including React for frontend rendering, Kentico CMS for content management, and Microsoft Azure for hosting and telemetry via Application Insights. It integrates Google Tag Manager and Cookiebot for analytics and cookie consent management, respectively. Accessibility is enhanced with the UserWay widget. Despite the advanced stack, the site suffers from slow load times and a large number of resources, indicating potential technical debt or optimization opportunities. SEO and metadata are adequately implemented, with canonical links and Open Graph tags present. The site is mobile optimized and accessible, supporting a broad user base.
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.
