0–100, higher is better. How it is calculated

Calibra is a Czech-based e-commerce company specializing in superpremium and premium pet food products for dogs, cats, and small rodents. The website presents a professional and comprehensive online store with a wide range of products including veterinary diets, dry food, wet food, treats, and subscription services. The brand has a strong presence in the Czech Republic and multiple international markets, supported by localized partner domains. Technically, the website uses modern web technologies such as jQuery, Google Tag Manager, and Google Analytics 4, with responsive design and accessibility features. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, although some security headers and incident response information are missing. Privacy compliance is well addressed with a detailed privacy policy and cookie management. Overall, the site is trustworthy and professionally maintained, though WHOIS data is unavailable likely due to privacy protection, which slightly reduces transparency.

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

6 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

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

Calibra operates in the retail and e-commerce sector focused on pet nutrition. Its competitive advantage lies in offering veterinary diets and subscription-based automatic orders, catering to pet owners seeking premium quality products. The business model is direct-to-consumer online sales with a strong brand identity and multi-country presence. Revenue streams include product sales and subscription services. The company targets pet owners in Czech Republic and abroad, leveraging social media and content marketing. The partnership ecosystem includes multiple country-specific domains, indicating a strategic international expansion. The website content and structure support a mature and growing business with good customer engagement.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and cookie consent mechanisms that comply with GDPR. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of explicit security headers like Content-Security-Policy and lack of published incident response or vulnerability disclosure policies indicate areas for improvement. The site does not provide a security.txt file or dedicated security contact channels, which could enhance transparency and trust. Overall, security practices are good but could be strengthened by adopting additional best practices and formal policies.

Recommendations

  1. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response information.
  3. Add explicit contact channels for security incidents or abuse reports to improve transparency and responsiveness.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.
  5. Enhance documentation of data retention policies and privacy compliance details for user assurance.

Technical notes

Notes

The website uses a modern and performant technology stack including jQuery 3.7.1, Google Tag Manager, and Google Analytics 4. It employs responsive design techniques and lazy loading for images, contributing to fast load times and good mobile optimization. The HTML structure includes semantic elements and accessibility features such as skip links and ARIA labels. SEO is supported by proper meta tags, Open Graph, Twitter cards, and JSON-LD structured data. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. Overall, the technical implementation is robust with room for minor enhancements in security headers and incident response integration.
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.
