ARO Treuhand GmbH is a Swiss fiduciary services company providing comprehensive accounting, tax, payroll, and business consulting services primarily to small and medium-sized enterprises across Switzerland. The company emphasizes a constructive and transparent partnership with clients, leveraging modern technologies and automated processes to deliver efficient and reliable solutions. Their market position is that of a trusted regional player with a focus on personalized service and professional expertise. Technically, the website is built on WordPress using the Themify Ultra theme and several professional plugins including Builder Slider Pro, Contact Form 7, and Complianz GDPR for cookie management. The site is well-optimized for mobile devices and includes modern security features such as HTTPS and Google reCAPTCHA v3 on forms. Performance is moderate with good SEO and accessibility basics in place. From a security perspective, the site enforces HTTPS and includes a cookie consent mechanism compliant with GDPR. However, it lacks some advanced security headers and a dedicated security policy or vulnerability disclosure page. No vulnerabilities or exposed sensitive data were detected. The WHOIS data is consistent with the business claims, enhancing trustworthiness. Overall, the website presents a professional and trustworthy digital presence with good compliance and security posture. Strategic improvements could include adding security headers, publishing a security policy, and implementing a security.txt file to further enhance transparency and security readiness.
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.
7 findings rated critical or high. Fix these first.

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.

Not counted
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.
