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

Konstrukce.cz is a professional Czech technical media platform operated by KONSTRUKCE Media, s.r.o., specializing in construction industry topics such as steel, concrete, and wood structures. The website serves as a digital extension of a prestigious bi-monthly magazine, offering articles, podcasts, event calendars, job listings, and subscription services targeting construction professionals. The domain has been active since 2001, indicating a well-established presence in the market. Technically, the site uses modern web technologies including Google Tag Manager, Microsoft Clarity, Facebook Pixel, and Cloudfront CDN, with responsive design and good SEO practices. However, there is a lack of visible privacy and cookie policies, and no explicit security headers detected, which are areas for improvement. The security posture is moderate with HTTPS usage but could benefit from enhanced headers and transparency. Overall, the site is trustworthy and professional but should enhance privacy compliance and security disclosures to align with best practices.

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. 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"

      • OWASP A04:2025
      • ASVS V3.4.1
    • High

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

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 business operates in the niche media sector focused on construction and civil engineering professionals in the Czech Republic. It leverages content publishing, digital articles, podcasts, and event advertising as revenue streams. The company maintains active social media channels to engage its audience. The long domain age and consistent branding support a strong market position. There is no evidence of parent or subsidiary companies. The business model is content-driven with a focus on technical expertise and industry relevance. Growth potential lies in expanding digital offerings and improving compliance and security transparency.

Security posture

The website enforces HTTPS and uses reputable analytics and tracking services. However, it lacks visible security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are recommended to mitigate common web vulnerabilities. No vulnerability disclosure or incident response contact information is provided, limiting transparency for security issues. The absence of privacy and cookie policies also indicates compliance gaps with GDPR and related regulations. The security score is moderate, reflecting a need for improved security best practices and user privacy protections.

Recommendations

  1. Publish a comprehensive privacy policy and cookie consent banner to improve GDPR compliance.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance security posture.
  3. Add a security.txt file or vulnerability disclosure policy to facilitate responsible reporting of security issues.
  4. Provide clear contact information for data protection officer and incident response to increase transparency.
  5. Regularly audit third-party scripts and tracking services to minimize privacy risks and improve user trust.

Notes

The website uses a modern tech stack with Bootstrap for responsive design, Google Fonts for typography, and multiple analytics/tracking tools including Google Tag Manager, Microsoft Clarity, and Facebook Pixel. Hosting leverages Amazon Cloudfront CDN for content delivery. The site shows good SEO optimization with meta tags and Open Graph data. Performance is moderate, with room for optimization. Accessibility features are basic but present. No CMS is explicitly detected. The site is mobile optimized and has clear navigation. Technical debt appears low but privacy and security implementations need enhancement.
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.
