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

The website www.vivus.cz represents a real estate business focused on selling new apartments in Prague, Czech Republic. The company behind the site is WebActive s.r.o., which appears as the developer and author of the website. The site showcases multiple ongoing and sold residential projects across various Prague districts, targeting individuals seeking affordable new housing. The business model centers on real estate development and sales, with a medium-sized market presence in the Prague region. Technically, the website is built on WebJET CMS and uses common web technologies such as jQuery and Bootstrap for responsive design. The site is well-structured with good SEO practices and mobile optimization. Cookie consent mechanisms are implemented, indicating some level of privacy compliance. However, no explicit privacy policy or terms of service pages were found, which is a compliance gap. From a security perspective, the site uses HTTPS (implied by canonical URLs) but lacks visible security headers and advanced security policies. No WHOIS data was retrievable for the domain, which raises concerns about domain registration legitimacy and trustworthiness. No incident response or security contact information is provided. Overall, the security posture is moderate but could be improved with better transparency and technical controls. The overall risk assessment suggests the website is functional and professional but has gaps in domain legitimacy verification and privacy compliance. Strategic recommendations include publishing privacy and terms policies, improving security headers, and clarifying domain registration details to enhance 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.

Priority findings

5 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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 24 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Vivus.cz operates in the real estate sector, focusing on new residential developments in Prague. The company leverages multiple projects in desirable locations, offering a range of apartment sizes and price points. Their competitive advantage lies in localized expertise and a portfolio of ongoing and completed projects. Revenue streams are primarily from apartment sales. The target customers are homebuyers in Prague seeking new construction. The company maintains an active social media presence and a dedicated portal for clients. Growth indicators include multiple projects under construction and recent sales completions. The partnership with WebActive s.r.o. suggests a professional digital presence. No parent or subsidiary companies were identified.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is used, ensuring encrypted communications. A cookie consent banner is implemented, supporting GDPR compliance. However, the absence of privacy and terms policies, lack of security headers (such as CSP, HSTS), and missing incident response contacts indicate compliance and security gaps. No vulnerable libraries or exposed sensitive data were detected in the HTML content. The lack of WHOIS data for the domain is a significant concern, as it impairs trust and domain legitimacy verification. The site does not appear to use advanced security frameworks or certifications. Overall, the security culture appears minimal but functional.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve compliance and user trust.
  2. Implement standard security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  3. Add a security.txt file and provide clear incident response contact information for vulnerability reporting.
  4. Conduct regular audits of third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Clarify domain registration details and ensure WHOIS information is publicly available to enhance domain trustworthiness.

Technical notes

Notes

The website uses a modern but common technology stack including WebJET CMS, jQuery, and Bootstrap for responsive design. The site loads multiple combined CSS and JS resources, indicating some optimization efforts. The presence of cookie consent scripts and GDPR-related JavaScript shows attention to privacy mechanisms. Performance is moderate with no explicit indicators of slow loading. Accessibility is basic with room for improvement. SEO is supported by meta tags and Open Graph data. Hosting provider and SSL certificate details are not explicitly available from the HTML content. Overall, the technical infrastructure is adequate for a medium-sized real estate business website.
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.
