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

Viladomy U Mlýna is a real estate development project focused on creating a new urban residential quarter in Vysočany, Prague. The website represents a medium-sized real estate developer, Metrostav Development, offering above-standard housing solutions. The site targets potential home buyers and residents interested in modern city living combined with natural surroundings. The business model centers on property development and sales within the Czech Republic real estate market. Technically, the website is built on the ProcessWire CMS and employs modern front-end technologies such as Swiper.js, Tippy.js, and Google Tag Manager, ensuring a good user experience with mobile optimization and SEO best practices. The site uses HTTPS and integrates a comprehensive cookie consent mechanism via Cookiebot, reflecting good privacy compliance and transparency in advertising and tracking practices. However, the WHOIS data shows a suspicious domain creation date in the future, which raises concerns about registration legitimacy. No explicit contact information or terms of service pages were found, which slightly impacts business credibility. Overall, the website is professional, secure, and compliant with GDPR, but improvements in transparency and WHOIS data accuracy are recommended.

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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
  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';…
  3. 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

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 · found on this site
  • 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 real estate sector, focusing on residential development in Prague. It leverages partnerships with Metrostav, a known construction and development firm, enhancing its market position. The business model is straightforward, selling residential units in newly developed urban quarters. The website's content and structure indicate a focus on quality and customer engagement, with clear navigation and detailed cookie and privacy policies. The advertising ecosystem includes major ad networks like Google and Seznam.cz, indicating active marketing efforts. The absence of direct contact details on the site suggests reliance on partner sites or offline channels for customer interaction. The suspicious WHOIS data could be a data entry error or a domain transfer, warranting further investigation.

Security posture

The website demonstrates a solid security posture with HTTPS enabled and cookie consent mechanisms in place. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of security headers such as Content-Security-Policy and lack of a security.txt file or incident response contacts indicate areas for improvement. The use of third-party scripts and ad networks is managed with user consent, aligning with GDPR requirements. The suspicious WHOIS data does not directly impact site security but affects trustworthiness. Overall, the site is secure but could enhance its security maturity by implementing recommended headers and incident response disclosures.

Recommendations

  1. Add explicit contact information including company emails and phone numbers on the website to improve business credibility.
  2. Publish terms of service and security policy pages to enhance transparency and compliance.
  3. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Create and publish a security.txt file to facilitate vulnerability disclosure and incident response.
  5. Investigate and correct the WHOIS domain registration data to align with the actual business timeline and improve trust.

Technical notes

Notes

The website uses a modern technology stack with ProcessWire CMS, Google Fonts, Swiper.js for sliders, Tippy.js for tooltips, and Google Tag Manager for analytics and marketing tags. Cookiebot is integrated for cookie consent management, ensuring GDPR compliance. The site is mobile optimized and uses canonical tags and Open Graph metadata for SEO and social media sharing. Hosting appears to be with REG-ZONER, a known Czech hosting provider. Performance is moderate with room for optimization. Accessibility features are basic but present. No broken elements or errors were detected in the provided HTML snippet. The technical infrastructure supports a professional and user-friendly experience but could benefit from enhanced security headers and performance tuning.
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.
