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

The website davar.cz is a personal site maintained by RNDr. David VARNER, Ph.D., featuring diverse hobbyist content including military history, technical monuments, Ford car collections, fossils, applied mechanics, and trainspotting. It serves a niche audience interested in these specialized topics and does not appear to operate as a commercial business. The domain is mature, registered since 2006, and hosted with Czech-based registrar and DNS providers, consistent with the website's Czech language content and focus. Technically, the site is built using legacy tools such as Microsoft FrontPage 6.0, with static HTML and CSS. There is no evidence of modern CMS, responsive design, or accessibility features. The site lacks HTTPS enforcement and security headers, which are critical for protecting user data and ensuring secure communications. No forms or user data collection mechanisms are present, reducing immediate data security risks but also limiting interactivity. From a security perspective, the absence of HTTPS and security headers lowers the security posture score. No privacy or cookie policies are present, indicating non-compliance with GDPR and related privacy regulations. The site does not use analytics or advertising scripts, minimizing tracking but also limiting business intelligence capabilities. Contact information is limited to a single email address, with no phone or physical address provided. Overall, the website is safe for general audiences, with no adult or explicit content detected. The site’s technical and security posture is basic and would benefit from modernization and implementation of standard security and privacy practices. The domain registration data is consistent and trustworthy, supporting the legitimacy of the site as a personal project rather than a commercial enterprise.

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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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.

Technical appendix

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

Business context

Business profile

Davar.cz operates as a personal informational website targeting enthusiasts of military history, technical heritage, automobiles, geology, and trains. The business model is non-commercial, focusing on content sharing rather than revenue generation. The site’s niche positioning and long domain age suggest a stable presence in its specialized community. There are no indications of partnerships, subsidiaries, or commercial services. The lack of analytics and marketing tools limits insights into visitor behavior and growth potential. The site’s content is primarily in Czech, targeting local or regional audiences interested in the specified topics.

Security posture

The website’s security maturity is low due to the absence of HTTPS, security headers, and privacy policies. While no forms or user inputs reduce the risk of data breaches, the lack of encryption exposes visitors to potential interception risks. There is no evidence of incident response or vulnerability disclosure mechanisms. Compliance with GDPR is not demonstrated, which could pose regulatory risks if personal data were collected. The site’s security culture appears minimal, reflecting its personal and hobbyist nature rather than a professional business environment.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure all communications.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Develop and publish privacy and cookie policies to comply with GDPR and inform visitors.
  4. Modernize the website technology stack to support responsive design and improve accessibility.
  5. Consider adding basic analytics with privacy-respecting configurations to understand visitor engagement.

Technical notes

Notes

The website is built with outdated technology, specifically Microsoft FrontPage 6.0, resulting in static HTML and CSS without modern responsive or accessibility features. Hosting is managed through REG-ONE registrar with DNS hosted on one.cz name servers, indicating a Czech-based infrastructure. Performance is moderate but could be improved with modern web standards. The absence of JavaScript frameworks or CMS limits functionality and scalability. There is no evidence of automated SEO or metadata optimization. The site would benefit from modernization to improve user experience, mobile compatibility, and security.
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.
