Medium risk. 6 critical or high findings in Security headers and GDPR outside view.

Security score

72/100

Risk levelMedium

0–100, higher is better. How it is calculated

BDO is a well-established professional services firm operating primarily in the finance sector, offering audit, tax, advisory, and consulting services. The domain bdo.ca has been registered since 2000 and is consistent with the company's Canadian presence. However, the website content is currently inaccessible due to a Cloudflare Turnstile CAPTCHA challenge, which blocks direct content access and prevents a full analysis of the website's content, policies, and contact information. The technical infrastructure includes Cloudflare protection and HTTPS with a clientTransferProhibited domain status, indicating good domain security practices. The lack of visible privacy, cookie, or terms of service policies and absence of contact details in the accessible content limits the assessment of compliance and user engagement features. Overall, the website demonstrates a strong security posture in terms of domain and SSL configuration but lacks accessible content for deeper evaluation.

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

6 findings rated critical or high. Fix these first.

  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.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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 businesses and organizations requiring professional financial and consulting services. The business model focuses on delivering audit, tax, advisory, and consulting services. The domain age and registrant information align with a mature and legitimate business entity. The website's current security measures, including Cloudflare WAF and CAPTCHA, suggest a focus on protecting digital assets and mitigating automated threats. However, the absence of accessible business content, policies, and contact information on the landing page limits insights into customer engagement strategies, marketing efforts, and partnership ecosystems.

Security posture

The website employs HTTPS and Cloudflare's security services, including Turnstile CAPTCHA, to protect against automated threats and ensure secure connections. The domain status clientTransferProhibited prevents unauthorized domain transfers, enhancing domain security. However, DNSSEC is not enabled, which is a recommended security enhancement for DNS integrity. No security headers are visible in the challenge page HTML, and no vulnerability disclosure or incident response information is accessible. The lack of visible privacy and cookie policies indicates potential compliance gaps. Overall, the security posture is moderate with strong perimeter defenses but limited transparency on internal security policies and user data protection.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies accessible from the website.
  3. Add visible security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear contact information including security incident response contacts and data protection officer details.
  5. Improve website accessibility by reducing reliance on CAPTCHA challenges for legitimate users and enhancing content availability.

Technical notes

Notes

The website is hosted behind Cloudflare, utilizing its security and performance services including Turnstile CAPTCHA for bot mitigation. The HTML content is minimal and serves as a security challenge page rather than a full website. No CMS or additional frameworks are detectable from the accessible content. The domain uses HTTPS with a valid SSL configuration. Performance and SEO cannot be assessed due to content blocking. The technical setup prioritizes security at the perimeter but limits user access and content delivery, which may impact user experience and SEO rankings. Modernization opportunities include enabling DNSSEC, improving content delivery post-challenge, and implementing standard web security headers.
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.
