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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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 Austria GmbH holds a strong market position as part of the BDO global network, leveraging its international brand and local expertise. The business model focuses on delivering auditing, tax, and consulting services to corporate clients, with specialized offerings in mergers, transactions, and cyber security. The company benefits from a broad partnership ecosystem and maintains active social media channels to engage clients. The website's content and structure support lead generation and client engagement, reflecting a medium to large enterprise scale. While WHOIS data is unavailable, the overall digital footprint and business information align with a reputable professional services firm.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and a robust cookie consent mechanism that blocks scripts until consent is given. CSRF protection cookies are present, and no sensitive data is exposed in the HTML. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program limits transparency. No vulnerabilities or suspicious activities were detected in the content. The security score is high, but improvements could be made by publishing explicit security and incident response information to enhance trust and compliance.

Recommendations

  1. Publish a dedicated security policy and incident response contact information on the website.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Regularly review and audit third-party scripts and tracking technologies to minimize security risks.
  4. Enhance transparency around data protection officer contact details to improve GDPR compliance.
  5. Maintain and update cookie consent mechanisms to reflect evolving privacy regulations and user expectations.

Technical notes

Notes

The website is built on the Kentico CMS platform, utilizing modern JavaScript libraries and third-party services such as Cookiebot for consent management, Microsoft Application Insights for telemetry, and SalesViewer for visitor analytics. Fonts are loaded from Google Fonts and CDNFonts, ensuring good typography. Accessibility is supported via the Userway widget. Performance is moderate with preloading of critical CSS and fonts, and asynchronous loading of analytics scripts. SEO is well addressed with meta tags, Open Graph data, and structured JSON-LD data. The site is mobile optimized and includes accessibility features, contributing to a positive user experience. Technical risks are minimal but should be monitored with respect to third-party script dependencies.
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.
