BDO España is a professional services firm specializing in audit, legal, fiscal, outsourcing, and advisory services. It operates as part of the global BDO network, serving businesses and professionals in Spain. The website reflects a mature digital presence with consistent branding and a clear focus on its core services. The technical infrastructure leverages modern analytics and marketing technologies including Google Analytics, LinkedIn Insight, and Microsoft Application Insights, hosted likely on Microsoft Azure. The site implements GDPR-compliant cookie consent mechanisms with detailed cookie categorization and user control. Security posture is generally strong with HTTPS enforced and IP anonymization in analytics, though explicit security headers are not detected and could be improved.

Overall, the website is professional, secure, and compliant, suitable for its target audience of business clients seeking professional advisory services.

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. 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.

  2. 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
      • RFC 4035
    • Medium

      No DMARC Record

      DMARC policy not configured

      What to do: Implement DMARC to prevent email spoofing

  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 DKIM record found

      DKIM adds cryptographic signatures to emails

      What to do: Configure DKIM with your email provider

    • Medium

      No MTA-STS Policy

      MTA-STS enforces TLS for email delivery

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

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 España holds a strong market position as a large professional services firm in Spain, offering a broad range of audit, legal, fiscal, and advisory services. Its business model focuses on B2B professional consulting with revenue streams from service contracts and advisory engagements. The company targets medium to large enterprises and professionals requiring compliance and advisory support. The website's use of advanced analytics and marketing tools indicates a strategic approach to client engagement and digital marketing. The absence of explicit contact details on the homepage suggests a possible focus on direct client relationships or contact via other channels. The firm benefits from the global BDO brand and network, enhancing credibility and reach. No suspicious or unrelated domains were found linked, supporting a focused and professional ecosystem.

Security posture

The website demonstrates a solid security posture with mandatory HTTPS, cookie consent mechanisms, and anonymized analytics tracking. However, the lack of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options represents an area for improvement. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The site does not publish a security policy, incident response contacts, or vulnerability disclosure information, which are recommended best practices for professional services firms handling sensitive client data. Overall, the security maturity is good but could be enhanced by formalizing security policies and improving HTTP header configurations.

Recommendations

  1. Implement and publish explicit security headers including CSP, HSTS, and X-Frame-Options to strengthen browser security.
  2. Add clear links to privacy policy and terms of service pages prominently on the website to improve transparency and compliance.
  3. Publish a security policy and incident response contact information to demonstrate readiness and build trust.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance accessibility features and provide visible contact information to improve user experience and trust.

Technical notes

Notes

The website uses a modern technology stack including Kentico CMS, Microsoft Azure hosting, and integrates multiple analytics and marketing tools such as Google Analytics, Google Tag Manager, LinkedIn Insight, and Microsoft Application Insights. The site is mobile optimized with good SEO practices including meta tags and structured data. Performance is moderate with preloading of fonts and CSS. Cookie consent is managed by Cookiebot with detailed cookie categorization and user controls. No major technical debt or outdated libraries were detected. Opportunities exist to improve security headers and accessibility compliance to further enhance the technical robustness.
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.
