Risk levelMedium

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

The website represents Asociace technických diagnostiků České republiky, a professional non-profit association focused on technical diagnostics and maintenance in the Czech Republic. It offers professional membership, certification, educational courses, and publishes an industry-specific journal. The organization has a long-standing presence since 1998, reflected in the domain age and consistent WHOIS data. The website is well-structured, mobile-optimized, and uses modern web technologies including Bootstrap and Google Fonts, managed via ISSA CMS. However, it lacks visible privacy and cookie policies, which are critical for GDPR compliance, and no contact emails or phone numbers are provided, limiting direct communication channels.

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

9 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

  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. 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 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';…

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.

Breach exposure

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

Leaked records that mention atdcr.cz, from OffSeq Breach.

No leaked records found

Breach holds no records for atdcr.cz right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The association targets technical diagnostics professionals, students, and industry experts in the Czech Republic. Its business model is based on membership fees, educational services, certification programs, and publishing. The website positions the organization as a credible and established entity with a niche focus. Partnerships with educational institutions and professional groups are evident. The lack of marketing or tracking tools suggests a focus on professional service rather than commercial advertising. The organization maintains a clear brand identity and consistent messaging, supporting trust and authority in its sector.

Security posture

The site uses HTTPS, ensuring encrypted communications. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No forms or user input fields are present on the homepage, minimizing attack surface. No incident response or abuse contact information is provided, which is a gap in security readiness. No vulnerable libraries or exposed sensitive data were detected. Overall, the security posture is moderate but could be improved with standard best practices and compliance documentation.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve GDPR compliance.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection.
  3. Add clear contact emails and phone numbers for general and security incident communications.
  4. Consider adding a vulnerability disclosure or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features and SEO metadata to improve user experience and discoverability.

Technical notes

Notes

The website is built on ISSA CMS with Bootstrap framework and uses Google Fonts for typography. It loads CSS and JS bundles efficiently and is mobile responsive. The site performance is fast with no broken elements detected. SEO metadata is minimal but present. No analytics or tracking scripts were found, indicating minimal user tracking. The site lacks advanced accessibility features but meets basic standards. Hosting provider details are not explicit but domain uses REG-ZONER name servers. Overall, the technical implementation is solid but could benefit from enhanced SEO, accessibility, and security header 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.
