Risk levelLow

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

BDO Norge is a leading international advisory and auditing firm with a strong presence in the Norwegian business and public sectors. The company offers a broad range of professional services including auditing, accounting, advisory, and legal services, targeting a diverse clientele from large multinational corporations to small and medium-sized enterprises. The website reflects a professional and consistent brand image aligned with its market position. Technically, the website employs modern technologies such as Google Tag Manager, Marketo Munchkin, Cookiebot for consent management, and Microsoft Application Insights for telemetry. The CMS identified is Kentico, indicating a robust content management infrastructure. The site is mobile-optimized and performs moderately well, with good SEO and accessibility features. From a security perspective, the site uses HTTPS with strong SSL configuration and implements a comprehensive cookie consent mechanism. However, explicit security headers are not detected in the provided content, and there is no visible security policy or incident response information published. No vulnerabilities or exposed sensitive data were found in the analysis. Overall, the website is trustworthy and professional, with extensive analytics and marketing tools in use. The lack of publicly available WHOIS data is due to privacy protection, which is justified for this type of business. Strategic recommendations include enhancing security headers, publishing security and incident response policies, and providing vulnerability disclosure information to improve transparency and trust.

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.

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

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

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 Norge holds a strong market position in the Norwegian finance sector, specializing in auditing, accounting, advisory, and legal services. Its business model focuses on professional services catering to a wide range of clients including public and private sectors. The company leverages partnerships with major technology and marketing platforms to enhance client engagement and operational efficiency. The website's content and structure indicate a mature digital presence with a focus on compliance and user experience. Growth indicators include the use of advanced analytics and marketing automation tools. No direct parent or subsidiary domains were identified from the content.

Security posture

The security posture of the website is solid with HTTPS enforced and a comprehensive cookie consent mechanism that supports GDPR compliance. The use of Microsoft Application Insights and other telemetry tools indicates active monitoring of site performance and usage. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for improvement. No incident response or security policy information is publicly available, which could be a gap in transparency. No vulnerabilities or exposed sensitive data were detected. Overall, the site demonstrates a good security maturity level appropriate for a professional services firm but could benefit from enhanced security controls and published policies.

Recommendations

  1. Implement and publish comprehensive security headers including CSP, HSTS, and X-Frame-Options to strengthen site security.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and user trust.
  3. Establish a vulnerability disclosure program and provide a security.txt file to facilitate responsible reporting.
  4. Enhance accessibility features to meet higher standards and improve user experience for all visitors.
  5. Regularly review and update privacy and cookie policies to ensure ongoing GDPR and other regulatory compliance.

Technical notes

Notes

The website uses a modern technology stack including JavaScript frameworks, Google Tag Manager, Marketo Munchkin for marketing automation, Cookiebot for consent management, and Microsoft Application Insights for telemetry. The CMS is Kentico, a robust enterprise-level platform. Performance is moderate with good mobile optimization and SEO practices. The site loads multiple external resources from trusted domains. No deprecated or vulnerable libraries were detected in the analyzed content. Technical debt appears low, but opportunities exist to improve security headers and accessibility compliance. Hosting provider details were not explicitly found.
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.
