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

1 finding rated critical or high. Fix these first.

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 Concunia GmbH holds a stable market position within the auditing and consulting sector in Germany, leveraging the global BDO brand. Its business model focuses on delivering essential financial and legal services to corporate and public clients. The firm benefits from a trusted brand and a comprehensive service portfolio including tax, legal, audit, and advisory services. The website supports this positioning by providing detailed service navigation and insights content. The absence of direct contact emails suggests a preference for controlled client engagement via forms. The company’s partnership ecosystem includes the global BDO network and related domains. Growth indicators are not explicit but the presence of news and insights sections indicates active market engagement.

Security posture

The website exhibits a mature security posture with HTTPS enforced and use of anti-forgery cookies to prevent CSRF attacks. Cookie consent is managed via Cookiebot, providing granular user control and transparency. Microsoft Application Insights is used for telemetry, indicating monitoring capabilities. However, the absence of explicit security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS reduces the overall security score. No exposed sensitive data or vulnerable libraries were detected. Incident response and security policy pages are not present, which could be improved to enhance transparency and readiness. Overall, the site is secure but could benefit from additional security hardening and documented policies.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish explicit security policy and incident response information to improve transparency and preparedness.
  3. Enhance SEO by adding meaningful meta descriptions, keywords, and structured data to improve search engine visibility.
  4. Provide clear and direct contact information including verified company emails and phone numbers to facilitate client communication.
  5. Improve accessibility features to meet higher standards and ensure inclusivity for all users.

Cookiebot is integrated for GDPR-compliant cookie consent management. The site uses Microsoft Application Insights for telemetry and monitoring, indicating a focus on performance and usage tracking. Hosting appears to be managed via Deutsche Telekom infrastructure, as inferred from the name servers. Performance is moderate with good mobile optimization and basic accessibility. SEO metadata is minimal, suggesting opportunities for improvement. The technical stack is modern and well-maintained, with no visible technical debt or deprecated technologies.
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.
