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

2 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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 operates in the finance and professional services sectors, offering audit, tax, advisory, and payroll outsourcing services. The firm targets Swedish companies across various industries including real estate, tech, and manufacturing. The business model is service-oriented with a focus on long-term client relationships and industry specialization. The website content and structure indicate a well-established brand with consistent messaging and strong trust signals such as privacy policies, cookie consent, and social media presence. Partnerships with platforms like Cookiebot and Microsoft Azure enhance operational capabilities. The company leverages content marketing through articles, events, and insights to engage its audience and maintain market leadership.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and security headers implied. Cookie consent is managed via Cookiebot with blocking mode enabled, ensuring compliance with privacy regulations. Analytics tools like Google Analytics and Microsoft Application Insights are configured with IP anonymization and consent-based activation. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy page and incident response contact details suggests room for improvement in transparency and readiness. Overall, the security measures align well with industry best practices for a professional services website.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement a security.txt file to facilitate vulnerability disclosure and improve transparency.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience.
  5. Regularly review and update third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using React and Kentico CMS, indicating a modern and scalable architecture. It integrates multiple third-party services including Cookiebot for consent management, Google Tag Manager for analytics, and Microsoft Application Insights for telemetry. Hosting appears to be on Microsoft Azure, inferred from cookie domains and telemetry endpoints. Performance is moderate with preloading of fonts and CSS, though some scripts are loaded asynchronously to optimize load times. The site is mobile responsive with good SEO practices including meta tags and Open Graph data. Technical risks are minimal but continuous monitoring of third-party dependencies is recommended to maintain security and performance.
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.
