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

Sousedé.cz is a Czech Republic-based digital platform focused on facilitating collaboration and management within residential communities, specifically SVJ (homeowners associations) and apartment buildings. The platform offers a comprehensive suite of services including legal duty monitoring, online voting, document management, communication tools, and integration with property management systems like DOMUS. Positioned as the leading portal for SVJ collaboration in the Czech market, Sousedé.cz targets SVJ committees, property managers, and apartment owners, aiming to simplify administration and enhance community engagement. Technically, the website is built using modern web technologies such as React with Next.js framework, ensuring a responsive and mobile-optimized user experience. It integrates multiple third-party services for analytics (Google Analytics), marketing automation (HubSpot), and advertising (Adform). The site employs HTTPS and cookie consent mechanisms, reflecting a commitment to user privacy and GDPR compliance. However, explicit security headers and incident response policies are not evident, suggesting areas for improvement in security posture. From a security perspective, the platform demonstrates good practices such as secure user zones with role-based access and GDPR-aligned privacy policies. No critical vulnerabilities or exposed sensitive data were detected in the analysis. The absence of WHOIS registration data is a notable concern, as it limits the ability to verify domain legitimacy and ownership, which could impact trustworthiness assessments. Overall, Sousedé.cz presents as a professional, well-structured, and user-focused platform with strong market positioning in the Czech residential property management sector. Strategic enhancements in security transparency and domain registration disclosure would further strengthen its credibility and trust with users and partners.

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.

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

Business profile

Sousedé.cz operates in the Real Estate sector, specifically targeting the niche of residential community management in the Czech Republic. Its business model revolves around providing SaaS solutions that streamline administrative tasks, legal compliance, and communication for SVJ committees and property managers. The platform's competitive advantage lies in its comprehensive feature set, integration capabilities (notably with DOMUS), and strong local market presence evidenced by testimonials and user base metrics. Revenue streams likely include subscription fees for platform access and premium services such as legal consultations and advanced integrations. The target customer segments are SVJ committees, property management companies, and apartment owners seeking efficient digital tools. Growth indicators include a sizable user base (over 45,000 users) and long operational experience (15 years). The partnership ecosystem includes integration with Anasoft's DOMUS system and marketing/analytics providers like HubSpot and Adform. The company maintains active social media channels to engage its community and promote services. Strategic observations suggest focusing on expanding integrations, enhancing security transparency, and possibly broadening services to related real estate management areas.

Security posture

The security maturity of Sousedé.cz is moderate to good. The site enforces HTTPS, employs secure user zones with role-based access controls, and provides GDPR-compliant privacy and cookie policies. These measures indicate a baseline commitment to protecting user data and privacy. However, the absence of explicit security headers (such as Content Security Policy, HSTS, X-Frame-Options) in the analyzed data suggests potential gaps in defense-in-depth strategies. No incident response or vulnerability disclosure information is publicly available, which could hinder timely communication and mitigation of security incidents. No exposed sensitive data or vulnerable libraries were detected, and forms appear to be standard with no obvious security flaws. The use of reputable third-party services for analytics and marketing is noted, but these also introduce privacy considerations that are partially mitigated by cookie consent mechanisms. Overall, while the platform demonstrates good foundational security practices, it would benefit from enhanced security header implementation, public incident response policies, and formal vulnerability disclosure channels to elevate its security posture and user trust.

Recommendations

  1. Implement and enforce comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen protection against common web attacks.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and preparedness for security events.
  3. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting and remediation of security issues.
  4. Enhance domain registration transparency by ensuring WHOIS data is complete and publicly accessible to improve trustworthiness.
  5. Consider adding verified company phone numbers and physical address details to bolster business credibility and user confidence.

Technical notes

Notes

The website is built on a modern React-based framework (Next.js) that supports server-side rendering and optimized performance. The tech stack includes integrations with Google Analytics for traffic analysis, HubSpot for marketing automation and forms, and Adform for advertising and retargeting. The site is mobile-optimized with responsive design, ensuring usability across devices. Performance appears moderate with multiple script chunks and preloads, indicating some complexity but no major delays. Accessibility features such as ARIA roles and focus management are present, contributing to a good user experience. No CMS is explicitly detected, suggesting a custom or headless architecture. Hosting provider details are not available from the data. The site uses standard favicon and manifest files for cross-platform compatibility. Technical risks include the lack of visible security headers and incomplete WHOIS data, which could affect operational security and domain legitimacy. Opportunities exist to streamline scripts and enhance SEO metadata further.
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.
