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

BigNews is a Czech content platform affiliated with Bigmat CZ, a cooperative focused on building materials and construction. The website provides articles, news, and information related to architecture, materials, suppliers, and partners, targeting professionals and enthusiasts in the construction sector. The site supports brand awareness and customer engagement through newsletters and social media integration. Technically, the website uses common JavaScript libraries such as jQuery and Font Awesome, with a moderate performance and good mobile optimization. Security posture is moderate, with cookie consent implemented but lacking visible security headers and incident response information. WHOIS data is missing, which reduces domain trustworthiness, but the website content and branding appear professional and consistent. Overall, the site is functional and trustworthy but would benefit from improved security practices and domain registration 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

7 findings rated critical or high. Fix these first.

  1. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

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.

Add-on

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

Technical appendix

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

Business context

Business profile

The website serves as a content marketing tool for Bigmat CZ, a cooperative in the building materials sector. It positions itself as a niche information provider with a focus on construction and architecture topics. The business model revolves around content dissemination to support the cooperative's market presence and customer engagement. The target audience includes construction professionals, architects, and partners. The site leverages partnerships with Bigmat CZ and integrates social media channels for broader reach. Growth indicators include regular content updates and newsletter subscriptions. The absence of detailed company registration data online suggests a need for enhanced transparency to strengthen business credibility.

Security posture

The website demonstrates a basic to moderate security posture. It employs HTTPS (assumed from typical modern standards, though not explicitly confirmed) and implements a cookie consent mechanism compliant with GDPR. However, no security headers such as Content Security Policy, HSTS, or X-Frame-Options were detected, which are recommended to enhance security. There is no public incident response or vulnerability disclosure information. No sensitive data exposure or vulnerable libraries were identified in the HTML content. The lack of WHOIS data and domain registration transparency is a concern for trust and legitimacy. Overall, the site should improve security headers, incident response readiness, and domain registration visibility to strengthen its security posture.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Ensure HTTPS is enforced site-wide and verify SSL/TLS configuration for best practices.
  3. Publish clear incident response and vulnerability disclosure policies to enhance transparency and trust.
  4. Improve domain registration transparency by ensuring WHOIS data is complete and publicly accessible.
  5. Add phone contact information and enhance accessibility features to improve user trust and compliance.

Technical notes

Notes

The website uses a standard tech stack with jQuery, Font Awesome, and jQuery fancyBox for UI components. The HTML structure is well-formed with responsive design elements and SEO-friendly meta tags. Performance is moderate, with external resources loaded from a CDN (res.lookweb.cz). No CMS is explicitly detected, suggesting a custom or proprietary platform. Accessibility is basic but could be improved with ARIA attributes and better keyboard navigation support. The site includes a cookie consent banner with granular control, indicating attention to privacy compliance. No outdated or vulnerable libraries were detected in the provided content. Hosting provider details are not available from the data. Overall, the technical implementation is solid but could benefit from enhanced accessibility and security improvements.
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.
