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

Opidum – reality a.s. operates in the real estate sector, developing residential apartments in the Czech Republic. The business model revolves around property development and direct sales, targeting local buyers near Prague. The company leverages digital marketing tools and analytics to optimize customer acquisition and engagement. The presence of GDPR-compliant cookie management and structured data indicates awareness of regulatory and SEO best practices. The project is relatively new, with domain registration in 2021, aligning with the development timeline. The company maintains clear contact channels and physical office locations, enhancing transparency and customer confidence. No partnerships or subsidiaries were identified from the data.

Security posture

The website demonstrates a good security baseline with HTTPS encryption, cookie consent management, and integration of Google reCAPTCHA to protect forms. However, explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options are not evident, which could improve defense against common web attacks. No incident response or security policy pages are published, which is a gap in transparency and preparedness. The use of third-party scripts is managed with consent, reducing privacy risks. No vulnerabilities or exposed sensitive data were detected in the analysis. Overall, the security posture is adequate for the business type but could benefit from enhanced policies and headers.

Recommendations

  1. Implement security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and plugins to mitigate vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Maintain and update GDPR and cookie consent mechanisms aligned with evolving regulations.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, Google Tag Manager, Google Analytics, Facebook Pixel, and Complianz GDPR plugin. The site uses Yoast SEO for search optimization and Contact Form 7 for user inquiries. Hosting and domain registration are managed by Wedos, a Czech provider, ensuring regional consistency. Performance is moderate with good mobile optimization and responsive design. Accessibility is basic but could be improved. The site uses structured data (JSON-LD) for enhanced SEO and branding. Some technical debt may exist in the form of missing security headers and potential over-reliance on multiple third-party scripts, which should be monitored for performance and security impact.
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.
