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

4 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

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 holds a solid market position in the German retail sector for personalized cards, leveraging a direct-to-consumer e-commerce model. Their competitive advantages include a wide product range, customization options, and fast shipping. The target customer segment includes individuals organizing weddings, births, and other personal events. The presence of a magazine and newsletter indicates active customer engagement and marketing efforts. The company maintains transparent contact channels and customer service, enhancing credibility. No parent or subsidiary relationships were detected, suggesting an independent medium-sized enterprise focused on retail. The partnership ecosystem includes social media platforms for brand presence and customer interaction.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented, enhancing protection against common web threats. The use of OneTrust for cookie consent indicates compliance with privacy regulations. No security policy or incident response pages were found, representing an area for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a security.txt file or explicit vulnerability disclosure policy suggests limited formalized security communication. Overall, the security maturity is good, with recommendations to formalize security policies and incident response contacts to further strengthen trust.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide explicit incident response contact information, such as security@ or abuse@ email addresses.
  3. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly review and update cookie consent and privacy policies to maintain GDPR compliance.
  5. Enhance transparency by adding certifications or trust badges related to security and data protection.

Technical notes

Notes

The website is built on a custom or proprietary CMS with a modern front-end stack including asynchronous CSS loading and Google Tag Manager integration. Hosting is provided via AWS, ensuring scalability and reliability. Performance is optimized with preconnect and dns-prefetch directives. The site is mobile-optimized with responsive design and accessibility considerations. SEO is supported by proper meta tags and structured data in JSON-LD format describing the organization. Cookie consent is managed by OneTrust, indicating compliance with EU regulations. No legacy or vulnerable libraries were detected. Technical risks are minimal, but the absence of explicit security policies and incident response mechanisms could pose reputational risks in case of security incidents.
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.
