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

7 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

      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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn

      What to do: Document all third-party data sharing in your privacy policy

  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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

  • Security headers: did not complete in this scan.
  • 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 is positioned as a medium-sized retail business specializing in promotional products and point of sale marketing solutions. Its business model combines e-commerce with B2B sales, offering both standard and customized products. The presence of multiple country-specific domains indicates a broad European market reach. The company leverages partnerships and maintains active social media channels to engage customers. The product range and services suggest diversified revenue streams including product sales, custom manufacturing, and graphic services. The website content and structure reflect a focus on customer experience and operational efficiency.

Security posture

The website exhibits a good security maturity level with HTTPS enforced site-wide, use of CSRF tokens, and a login process that supports two-factor authentication. Cookie consent is managed via Usercentrics CMP, indicating attention to privacy regulations. However, the absence of advanced security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. Incident response and security policy information are not publicly available, which could be enhanced to improve transparency and readiness.

Recommendations

  1. Implement additional HTTP security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy to strengthen defense against common web attacks.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures to increase user trust and compliance.
  3. Provide clear incident response contact channels such as security@ or abuse@ email addresses for reporting security issues.
  4. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerable dependencies.
  5. Enhance accessibility features to improve compliance with standards and broaden user inclusivity.

Technical notes

Notes

The website is built on the OXID eShop CMS platform, utilizing Bootstrap for responsive design and jQuery for client-side scripting. It integrates Usercentrics for GDPR-compliant consent management and Google Tag Manager for analytics and marketing tags. The site employs service workers for progressive web app capabilities. Performance is moderate with good mobile optimization and SEO practices including meta tags and structured data. The technical implementation is modern but could benefit from enhanced accessibility and additional security headers. Hosting provider details are not explicitly identified from the 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.
