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

Ridera Development is a small real estate development company focused on modern housing projects in the Moravian-Silesian Region of the Czech Republic. Their website highlights current projects such as 'Bydlení Ema' and 'Rezidence Keltičkova', targeting potential home buyers and residents in the region. The business model centers on real estate development and providing housing documentation to clients. Technically, the website is built on WordPress using the Elementor page builder and Astra theme, indicating a modern and flexible digital infrastructure. The site is mobile-optimized and uses HTTPS, but lacks some security headers and privacy compliance features. Security posture is moderate with room for improvement in policy transparency and incident response readiness. Overall, the website is professional and relevant but limited in publicly available business and security information, and the absence of WHOIS data reduces domain trustworthiness. Strategic recommendations include adding privacy and cookie policies, contact information, and enhancing security headers to improve compliance and trust.

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

    • 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"

      • 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 company operates in the regional real estate sector with a focus on residential housing projects. Their market positioning is localized within the Moravian-Silesian Region, serving home buyers and residents. The website links to partner project domains, indicating a partnership ecosystem. Revenue streams likely derive from property sales and development services. The business model is straightforward, focusing on construction and management of housing projects. Growth indicators are not explicitly stated, and no parent or subsidiary companies are identified. The lack of detailed business information and contact data limits transparency but the site content is professionally presented and consistent with real estate development activities.

Security posture

The website employs HTTPS, ensuring encrypted communications, which is a fundamental security measure. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. The site lacks visible privacy policies, cookie consent mechanisms, and incident response contact channels, indicating gaps in compliance with GDPR and best security practices. The WHOIS data is unavailable, which may indicate privacy protection or registration issues, impacting trust. Overall, the security posture is moderate but could be significantly improved by implementing recommended headers, policies, and transparency measures.

Recommendations

  1. Implement comprehensive privacy and cookie policies with visible links on the website.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  3. Publish contact information including security incident response contacts and consider a vulnerability disclosure policy.
  4. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities.
  5. Enhance website transparency by providing WHOIS or domain registration details if possible.

Technical notes

Notes

The website is built on a modern WordPress platform using the Elementor page builder and Astra theme, which supports responsive design and good user experience. It uses common libraries such as jQuery and Swiper for UI components. The site loads external fonts from Google Fonts and uses HTTPS for secure connections. Performance is moderate with no major issues detected, though no explicit performance optimization indicators were found. Accessibility features are basic, with some screen-reader text and skip links present. SEO optimization is basic with meta tags and canonical links but lacks advanced structured data or Open Graph metadata. The technical stack is standard for small to medium business websites, offering flexibility but requiring ongoing maintenance to ensure security and performance.
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.
