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

The website www.durisol-zdivo.cz presents a specialized construction business focused on the Durisol building system, which integrates wood, concrete, and insulation to create energy-efficient, healthy, and durable family homes. The site targets individuals and families in the Czech Republic interested in innovative and sustainable building technologies. The business offers consultation, project design, construction services, and DIY support, positioning itself as a niche player in the real estate and energy-efficient construction sector. Technically, the website employs a modern tech stack including Bootstrap, jQuery, Owl Carousel, and Google services such as Analytics and Maps. The site is mobile-optimized with good navigation and content relevance. However, performance is moderate and accessibility features are basic. No CMS or hosting provider details were detected. From a security perspective, the site lacks visible security headers and a privacy policy, which are important for compliance and user trust. HTTPS status is unknown from the data, but Google Analytics and cookie consent are implemented, indicating some privacy awareness. The absence of WHOIS data is a significant concern, reducing domain trustworthiness and raising questions about domain registration legitimacy. Overall, the website is functional and professional but would benefit from enhanced security practices, transparent privacy policies, and verified domain registration information to improve trust and compliance.

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

10 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

The business operates in the real estate and energy-efficient construction sector, offering a unique building system (Durisol) that combines ecological materials and advanced technology. Its competitive advantage lies in the patented building blocks and integrated insulation technology. Revenue streams likely include material sales, project consulting, and construction services. The target customers are homeowners and builders seeking sustainable and healthy housing solutions. The partnership with www.energy-domy.cz suggests a collaborative ecosystem for project offerings. Growth potential exists in the niche market of energy-saving construction, but lack of transparent domain registration and privacy policies may hinder trust with new customers.

Security posture

The current security posture is moderate but has notable gaps. The absence of security headers and privacy policy reduces compliance with GDPR and best practices. No incident response or vulnerability disclosure information is provided. The site uses Google Analytics and advertising scripts, which require proper user consent and data protection measures. No forms or sensitive data collection points were found, reducing immediate risk. The missing WHOIS data is a red flag for domain legitimacy. Overall, the site should improve transparency, implement security headers, and provide clear privacy and security policies to enhance its security maturity.

Recommendations

  1. Implement a comprehensive privacy policy page detailing data collection and GDPR compliance.
  2. Ensure HTTPS is properly configured and enforce secure connections site-wide.
  3. Add security HTTP headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Publish terms of service and incident response contact information to improve transparency.
  5. Verify and publish domain registration details to increase trustworthiness and legitimacy.

Technical notes

Notes

The website uses a standard modern front-end stack with Bootstrap and jQuery, enhanced by Owl Carousel for interactive elements and Lightbox for image galleries. Google Analytics and Google Ads scripts are integrated for tracking and marketing. The site is mobile responsive and SEO optimized with proper meta tags. However, no CMS or backend technology is identified, and hosting details are unknown. Performance is moderate, with potential improvements in loading speed and accessibility. The site lacks advanced security headers and privacy documentation, which are critical for compliance and user trust.
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.
