Risk levelMedium

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

BDO Austria GmbH is a well-established professional services firm operating as part of the global BDO network. The company provides a broad range of services including auditing, tax consulting, corporate finance, consulting, and sustainability advisory primarily targeting Austrian businesses and organizations. Their market position is strong, supported by comprehensive service offerings and a consistent brand presence. Technically, the website is built on modern frameworks such as ASP.NET and React, hosted on Microsoft Azure, and managed via Kentico CMS. However, the site currently lacks a valid SSL certificate and does not support modern TLS protocols, which is a critical security shortfall. Security headers are properly configured, and privacy compliance is supported by Cookiebot for consent management. Overall, the website is content-rich, professionally designed, and trustworthy, but the absence of HTTPS significantly impacts the security posture and overall risk profile.

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

5 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  2. 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

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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 leverages its membership in the international BDO network to offer a wide array of financial and consulting services. Their business model focuses on professional services with a strong emphasis on tax, auditing, corporate finance, and sustainability. The company targets medium to large enterprises and public sector entities in Austria, providing tailored solutions including cyber security assessments and grant consulting. The website reflects a mature digital presence with active event promotion, webinars, and a career portal. Partnerships and social media engagement further enhance their market reach. The domain registration and DNS configurations are consistent with the company's Austrian base, reinforcing legitimacy.

Security posture

The website demonstrates partial adherence to security best practices with several HTTP security headers implemented, including HSTS, X-Content-Type-Options, X-Frame-Options, and a restrictive Content Security Policy. DNS records include SPF and DMARC for email security. However, the lack of a valid SSL certificate and absence of TLS protocols severely undermine the security posture, exposing users to potential interception and trust issues. No vulnerabilities such as Heartbleed or POODLE were detected, but the missing HTTPS is a critical vulnerability. Incident response and security policy information are not publicly available on the site, indicating potential gaps in transparency and readiness.

Recommendations

  1. Immediately obtain and deploy a valid SSL/TLS certificate to enable HTTPS and secure user connections.
  2. Enable and enforce modern TLS protocols (TLS 1.2 or TLS 1.3) to ensure secure communications.
  3. Implement OCSP stapling and session resumption to improve SSL performance and security.
  4. Publish clear security policies and incident response contact information to enhance transparency and trust.
  5. Continue to maintain and update security headers and privacy compliance mechanisms regularly.

Technical notes

Notes

The website is built on a modern technology stack including ASP.NET backend and React frontend, supported by Kentico CMS for content management. Hosting is on Microsoft Azure, indicating a scalable and reliable infrastructure. The site uses multiple third-party scripts for analytics, consent management, and accessibility, including Cookiebot, SiteImprove, SalesViewer, and Microsoft Application Insights. Performance metrics indicate slow loading, possibly due to heavy scripts or unoptimized resources. The site is mobile optimized and accessible, with good SEO practices including meta tags, Open Graph, and structured data in JSON-LD format. Technical debt is moderate, with the critical need to fix SSL/TLS issues to avoid business and security risks.
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.
