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. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 targets industrial and scientific sectors requiring specialized measurement and hygiene products. Their long domain age and consistent branding indicate a stable market presence. The use of Shopify enables scalable e-commerce operations with integrated marketing and analytics tools. The presence of multiple product categories and detailed navigation suggests a mature product catalog. No evidence of partnerships or subsidiaries was found in the domain or website content. The company leverages Google Ads and Shopify Pixels for marketing and retargeting, indicating active customer acquisition strategies.

Security posture

The website enforces HTTPS with strong SSL configuration and includes standard security headers such as Content-Security-Policy and X-Frame-Options. Cookie consent is implemented with opt-in mechanisms, supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a public security policy, vulnerability disclosure, or incident response contacts limits transparency. The site benefits from Shopify's inherent security features but could improve by publishing explicit security documentation and incident response procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Implement and publish a vulnerability disclosure policy or security.txt file.
  3. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  4. Enhance accessibility features to improve compliance with WCAG standards.
  5. Regularly audit third-party scripts and tracking pixels to minimize security risks.

Technical notes

Notes

The website is built on the Shopify platform using modern web standards including HTML5, CSS3, and JavaScript. It uses Shopify Liquid templating and integrates multiple Shopify assets and third-party fonts. Performance is moderate with deferred and async loading of scripts. The site is mobile optimized with responsive design and includes SEO metadata such as Open Graph and Twitter Card tags. Accessibility is basic but could be improved. Hosting is provided by Krystal Hosting Ltd, a reputable UK hosting provider. The technical stack is well-suited for e-commerce but could benefit from enhanced accessibility and performance optimizations.
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.
