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

9 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

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

Brumlovka operates in the real estate sector, specifically commercial leasing in Prague 4. Its competitive advantage lies in offering a unique business park environment with offices, retail, fitness, and event spaces. The business model revolves around property leasing and community engagement through events and services. The target customers include companies seeking office space and retail tenants. The website reflects a medium-sized enterprise with a strong brand presence and parent company backing. Partnerships with Passerinvest Group and related virtual tour services enhance market positioning. Growth indicators include active event promotion and continuous service expansion. The company maintains a professional digital presence aligned with its market niche.

Security posture

The website exhibits a mature security posture with HTTPS enabled and cookie consent implemented, supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were identified in the HTML content. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not evident and could be added to strengthen defenses. There is no visible incident response or vulnerability disclosure information, which could be improved. Overall, the site follows good security practices but has room for enhancement in header policies and formal security documentation.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Add a security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  4. Regularly audit and update all WordPress plugins and themes to prevent vulnerabilities.
  5. Consider publishing an incident response policy or contact channel for security issues to build trust.

Technical notes

Notes

The website is built on WordPress using the Avada theme and several plugins including Yoast SEO, WPML for multilingual support, and SmartEmailing for marketing. It integrates Google Maps API and Google Analytics for location and analytics services. The site is hosted likely by Active24, consistent with the registrar information. Performance is moderate with good mobile optimization and SEO practices. The use of structured data (JSON-LD) enhances search engine visibility. Technical debt appears low, but security header implementation and accessibility could be improved. The site is well maintained with modern web technologies and a professional design.
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.
