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

6 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.

Breach exposure

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 sector, focusing on residential development and sales. The project targets active individuals seeking balance between city life and nature. The business model centers on property development and sales, supported by financing options. Market positioning is that of a quality, modern residential project in a desirable Prague location. The company benefits from the strong brand and resources of its parent, Metrostav a.s. The partnership ecosystem includes major ad networks and analytics providers, ensuring effective marketing and user tracking. Growth indicators include recent domain registration and active marketing campaigns. Strategic observations suggest leveraging the parent company's reputation and expanding contact information visibility to enhance customer engagement.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive cookie consent, and no visible sensitive data exposure. The use of Cookiebot ensures GDPR compliance and user privacy controls. However, the absence of explicit security headers such as Content Security Policy, X-Frame-Options, and HSTS is a gap that should be addressed to harden security. No vulnerabilities or malware indicators were detected. Incident response and security policy pages are not present, which could be improved to enhance transparency and readiness. Overall, the security culture appears adequate for the business type but can benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement standard security headers (CSP, HSTS, X-Frame-Options) to improve security posture.
  2. Publish explicit security and incident response policies to increase transparency and trust.
  3. Add clear contact information including company emails and phone numbers for customer support.
  4. Regularly audit third-party scripts and cookies for compliance and security risks.
  5. Enhance accessibility features to improve user experience for all visitors.

Technical notes

Notes

The website is built on ProcessWire CMS, using modern HTML5, CSS3, and JavaScript technologies. It integrates Cookiebot for cookie consent management and Google Tag Manager for analytics and marketing. Hosting is provided by REG-ZONER, a reputable registrar and hosting provider. Performance is moderate with good mobile optimization and SEO practices. The site uses structured data (JSON-LD) for breadcrumbs, aiding search engine indexing. Technical debt appears low, but the lack of security headers and limited accessibility features indicate areas for modernization. Overall, the technical infrastructure supports the business goals effectively with room for incremental improvements.
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.
