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

Buus Jensen is a well-established, independent accounting and auditing firm based in Copenhagen, Denmark. The company offers a range of professional services including auditing, economic advisory, and a proprietary digital bookkeeping system called BUUS JENSEN Online. With over 50 employees and a stable leadership team of seven partners, the firm emphasizes personalized client relationships and comprehensive financial support. Their market position is that of a trusted mid-sized player in the Danish finance sector, supported by partnerships with recognized accounting networks such as UHY and Revisorgruppen Danmark. Technically, the website is built on WordPress with modern plugins for SEO, multilingual support, and cookie consent management. The site employs Google Analytics and Google Tag Manager for analytics and tracking, alongside Google reCAPTCHA for form security. The website is mobile-optimized, accessible, and SEO-friendly, reflecting a mature digital infrastructure. Performance is moderate, with room for optimization. From a security perspective, the site uses HTTPS and implements a comprehensive cookie consent mechanism compliant with GDPR. The contact form is protected by reCAPTCHA, and no sensitive data is exposed in the HTML. However, some security headers are not explicitly detected and could be improved. The absence of WHOIS data limits domain trust verification, but the professional presentation and consistent business information mitigate concerns. Overall, Buus Jensen presents a professional and trustworthy online presence with strong privacy compliance and a solid technical foundation. Strategic improvements in security headers and incident response visibility would further enhance their security posture and trustworthiness.

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

3 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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.

    • 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 · found on this site
  • 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.

Business context

Business profile

Buus Jensen operates in the finance sector, targeting businesses and individuals in need of auditing, accounting, and financial advisory services in Copenhagen. Their competitive advantage lies in their personalized approach, experienced leadership, and integration of digital bookkeeping solutions. Revenue streams likely include auditing fees, advisory services, and subscription or usage fees for their online bookkeeping platform. The firm demonstrates growth through content updates and partnerships with reputable accounting networks. Their digital presence supports multilingual access, indicating an openness to international or expatriate clients. The partnership ecosystem with UHY and Revisorgruppen Danmark enhances credibility and market reach. Operationally, the firm focuses on client-centric service delivery and continuous digital enhancement.

Security posture

The website exhibits a good security maturity level with HTTPS enforced and use of Google reCAPTCHA to protect forms. The cookie consent banner is comprehensive and GDPR-compliant, allowing granular user consent. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers like X-Frame-Options and Content-Security-Policy in the visible HTML suggests potential areas for improvement. Incident response and security policy information are not publicly available, which could be a compliance gap. The lack of WHOIS data limits domain legitimacy verification but does not directly impact website security. Overall, the security posture is solid for a professional services website but could benefit from enhanced header policies and transparency in security governance.

Recommendations

  1. Implement and verify HTTP security headers such as X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to strengthen browser security.
  2. Publish a security policy and incident response contact information to improve transparency and compliance.
  3. Regularly update WordPress core and plugins to mitigate vulnerabilities.
  4. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  5. Conduct periodic security audits and penetration testing to proactively identify and remediate risks.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including Yoast SEO for search optimization, Contact Form 7 for form management, Weglot for multilingual support, and Cookie Information for consent management. Google Analytics and Google Tag Manager are used for analytics and tracking, while Google reCAPTCHA secures user input forms. The site is mobile-optimized and accessible, with good SEO practices evident in meta tags and structured data (JSON-LD). Performance is moderate, suggesting potential for optimization in loading times. Hosting provider details are not explicitly found. The technical implementation reflects a mature and professional digital infrastructure suitable for a mid-sized accounting firm.
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.
