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

Cetris s.r.o. operates the website www.cetrishobby.cz, promoting and selling CETRIS® HOBBY boards designed for hobbyists and small construction projects. The company targets DIY enthusiasts and gardeners in the Czech Republic, offering a niche product with detailed pricing, project ideas, and direct factory sales. The website is well-structured, visually consistent, and provides clear contact information and social media links, supporting a professional business presence. Technically, the site uses Google Analytics and Google Maps APIs, with responsive design and moderate performance.

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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, YouTube, Google APIs

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

  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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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

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 positions itself as a manufacturer and direct seller of specialized construction boards for hobby and garden use. Its business model focuses on manufacturing, direct sales at the factory, and community engagement through project inspiration. The market niche is well-defined, targeting DIY hobbyists in the Czech Republic. The website supports sales with pricing tables, promotional discounts, and contact details. The presence of social media channels indicates active customer engagement. The lack of WHOIS data is a concern but does not negate the visible business operations. The company appears medium-sized with a focused product line and regional market presence.

Security posture

The website uses HTTPS, which is mandatory for secure communication. However, no security headers such as Content Security Policy, HSTS, or X-Frame-Options were detected, which are recommended best practices. No exposed sensitive data or vulnerable libraries were found in the HTML. The site lacks published security policies, incident response contacts, or vulnerability disclosure mechanisms. Cookie consent is implemented, indicating some privacy awareness. Overall, the security posture is moderate but could be enhanced by implementing security headers, publishing privacy and security policies, and establishing incident response contacts.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  3. Establish and publicize an incident response contact or security email to handle security issues and disclosures.
  4. Improve accessibility features to ensure compliance with standards and enhance user experience for all visitors.
  5. Verify and update WHOIS domain registration information to improve domain legitimacy and trust signals.

Technical notes

Notes

The website is built with standard HTML5, CSS3, and JavaScript, utilizing Google Maps API for location services and Google Analytics for traffic monitoring. The site is mobile responsive with good navigation and SEO meta tags. No CMS or advanced frameworks were detected, indicating a custom or lightweight implementation. Performance is moderate, with room for optimization. The absence of security headers and incomplete privacy documentation are technical gaps. Hosting provider details are not disclosed. Overall, the technical infrastructure supports the business needs but could benefit from modernization and enhanced security configurations.
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.
