Grant Thornton Switzerland / Liechtenstein · Finance · Switzerland
Low risk. 1 critical or high finding in SSL/TLS.
Grant Thornton Switzerland / Liechtenstein is a well-established professional services firm providing audit, tax, advisory, and consulting services primarily to businesses in Switzerland and Liechtenstein. The firm operates as a member of the global Grant Thornton International network, positioning itself as a leading mid-tier player in the finance sector within its geographic market. The website reflects a professional and consistent brand image aligned with international standards, targeting corporate clients seeking high-quality financial and advisory services. Technically, the website employs modern analytics and marketing technologies such as Google Analytics, Microsoft Clarity, Optimizely, and OneTrust for cookie consent management, indicating a mature digital infrastructure. The site is mobile-optimized with good SEO and accessibility features, although some technical details like CMS and hosting provider are not explicitly identified. From a security perspective, the site enforces HTTPS with strong SSL configuration and implements key security headers. Privacy compliance is robust with comprehensive privacy and cookie policies and active consent mechanisms. However, the absence of a dedicated security policy, incident response information, and vulnerability disclosure mechanisms suggests areas for improvement in transparency and security maturity. Overall, the website presents a low-risk profile with strong business credibility and privacy compliance. Strategic recommendations include publishing explicit security and incident response policies and implementing a vulnerability disclosure program to enhance trust and security posture further.
Scanned
NIS2 Art. 21(2)
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.
1 finding rated critical or high. Fix these first.
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
SSL certificate uses 256-bit key, which is considered weak
What to do: Use at least 2048-bit RSA or 256-bit ECC key

Each check with its score, findings and the evidence it collected.
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.

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.
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, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
