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

Arendt operates in the finance and legal sectors, targeting businesses and professionals requiring specialized advisory services in Luxembourg. The firm leverages a diversified service portfolio including legal, tax, regulatory, and investor services, complemented by educational offerings. The website's structured navigation and content indicate a client-centric approach with clear market positioning as a leading Luxembourg advisory firm. The presence of social media channels and compliance with GDPR and cookie regulations reflect a mature digital presence. No direct contact details were found in the analyzed content, suggesting contact is likely managed through dedicated pages or forms elsewhere on the site.

Security posture

The website demonstrates a good security posture with HTTPS enabled and cookie consent implemented, indicating compliance with privacy regulations. However, the absence of explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security hardening. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency in handling security incidents. Overall, the security maturity is moderate to good, with room for improvement in formalizing security communications and technical headers.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance site security.
  2. Publish a dedicated security policy and incident response page with clear contact channels for reporting security issues.
  3. Add a vulnerability disclosure or security.txt file to improve transparency and encourage responsible reporting.
  4. Include explicit company contact emails and phone numbers on accessible pages to improve user trust and communication.
  5. Regularly review and update third-party plugins and analytics tools to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS using a variety of plugins such as FacetWP for filtering, Sugar Calendar for events, Complianz for GDPR cookie consent, and Matomo and Parsely for analytics. The site uses modern JavaScript libraries and CSS for responsive and accessible design. Performance is moderate with asynchronous loading of scripts and prefetching of DNS for external resources. Accessibility features include an accessibility settings modal for contrast, font, and spacing adjustments. SEO is supported by structured data (JSON-LD) and Open Graph metadata. Hosting provider details are not explicitly disclosed in the HTML content.
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.
