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

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

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

The company operates in the manufacturing and retail sectors, focusing on art and office supplies. It leverages a multi-channel approach including physical stores, an e-commerce platform, and product configurators. The brand benefits from a long heritage and consistent branding, which supports customer trust and market differentiation. The presence of a blog and extensive product catalog indicates active engagement with customers and marketing efforts. Partnerships with related domains for catalog, e-shop, and promotions strengthen the ecosystem. The company targets a broad audience from children to professional artists, emphasizing product safety and quality. Growth indicators include a large product portfolio and international presence. No suspicious or fraudulent patterns detected in business operations.

Security posture

The website enforces HTTPS and uses Google Tag Manager for analytics, indicating basic security hygiene. Cookie consent mechanisms are in place, supporting privacy compliance. However, the absence of detected security headers such as Content-Security-Policy or X-Frame-Options suggests room for improvement in mitigating common web vulnerabilities. No exposed sensitive data or vulnerable libraries were identified in the analysis. There is no public incident response or security policy information, which could enhance transparency and readiness. Overall, the security posture is moderate but could be strengthened with additional headers and documented policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Verify and publish domain WHOIS registration details to improve trust and transparency.
  3. Add a dedicated security policy and incident response information accessible to users and partners.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.
  5. Enhance accessibility features and SEO metadata for improved user experience and search engine ranking.

Technical notes

Notes

The website is built using React 17.0.2 and related modern JavaScript libraries, ensuring a dynamic and responsive user interface. It loads external resources securely via HTTPS, including Google Tag Manager for analytics and an S3-hosted media library for images. The site includes polyfills for URLSearchParams and fetch, indicating support for older browsers. Performance is moderate with some lazy loading placeholders observed. Mobile optimization is good, with responsive design and viewport meta tags. SEO is supported by meta descriptions, keywords, and Open Graph tags, although some OG title and description fields are empty. No CMS is explicitly detected, suggesting a custom or headless CMS solution. Hosting provider details are not available from the data. Overall, the technical infrastructure is modern and well-implemented with opportunities for performance tuning and enhanced accessibility.
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.
