Grant Thornton Sweden AB is a well-established professional services firm specializing in audit, tax, advisory, accounting, and payroll services. The company is part of the global Grant Thornton International Ltd network, providing both local and international expertise. Their website reflects a strong market position with a comprehensive service offering tailored to various industries including tech, healthcare, private equity, and non-profit sectors. The site is professionally designed with clear navigation and rich content aimed at business clients and entrepreneurs in Sweden. Technically, the website employs modern JavaScript libraries and tools such as jQuery, Optimizely for experimentation, OneTrust for privacy compliance, and Azure Application Insights for monitoring. The site is hosted on a robust infrastructure likely leveraging Microsoft Azure, ensuring good performance and scalability. Mobile optimization and accessibility are well addressed, contributing to a positive user experience. From a security perspective, the site enforces HTTPS, uses cookie consent mechanisms, and integrates monitoring tools, indicating a mature security posture. However, explicit security policies, incident response contacts, and vulnerability disclosure mechanisms are not publicly available, suggesting areas for improvement. No critical vulnerabilities or exposed sensitive data were detected. Overall, the website presents a low-risk profile with strong compliance and professionalism. Strategic recommendations include publishing detailed security and incident response policies, implementing security.txt for vulnerability disclosures, and enhancing security headers to further strengthen the security posture.

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

15 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

  3. 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: Telnet

      Port 23 (Telnet) is publicly accessible - Telnet - Unencrypted remote access

      What to do: Immediately restrict access to Telnet 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
    • Critical

      Critical Service Exposed: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB 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 SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: MSSQL

      Port 1433 (MSSQL) is publicly accessible - MSSQL - Database server

      What to do: Immediately restrict access to MSSQL 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

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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Grant Thornton Sweden AB operates in the finance sector, offering essential services such as auditing, tax consulting, advisory, and accounting. Their business model focuses on providing tailored solutions to a diverse client base including SMEs, tech companies, private equity firms, and non-profits. The company leverages its global network to offer international services, enhancing its competitive advantage. The website's content and structure indicate a focus on thought leadership, client education, and engagement through events and newsletters. Partnerships with career platforms and a global network site reflect a comprehensive ecosystem supporting growth and talent acquisition.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, use of privacy management tools (OneTrust), and integration of monitoring services (Azure Application Insights). No direct contact emails or phone numbers are exposed, reducing phishing risks. The absence of explicit security policies and incident response contacts is a gap in transparency and readiness. No vulnerable libraries or exposed sensitive data were found. The site could benefit from enhanced security headers and a published vulnerability disclosure policy to improve trust and compliance.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and controls.
  2. Implement and publicly link a security.txt file to facilitate responsible vulnerability disclosure.
  3. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  4. Enhance HTTP security headers including Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options.
  5. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern tech stack including jQuery, Optimizely for A/B testing, OneTrust for cookie consent, and Azure Application Insights for telemetry. It employs responsive design techniques and accessibility best practices, ensuring usability across devices. The hosting environment is inferred to be Microsoft Azure, providing reliable performance. The site uses structured data (JSON-LD) and Open Graph metadata for SEO and social sharing. Performance is moderate, with opportunities to optimize loading times further. The technical implementation is robust but could be improved by adopting additional security headers and enhancing privacy disclosures.
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.
