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

Dokonalý nájemník is a Czech Republic based real estate rental management service specializing in providing landlords with guaranteed rent and comprehensive care of their apartments. The company leverages 14 years of rental market experience to offer hassle-free rental solutions including tenant management, maintenance, and rent calculation tools. Their market position is supported by a portfolio worth billions of Czech crowns and a growing client base. The website is professionally designed, mobile optimized, and provides clear navigation and relevant content targeted at property owners seeking reliable rental income. Technically, the website is built on the MySUITU CMS platform, utilizing modern web technologies such as Google Maps API for location services, jQuery for interactivity, and cookie consent tools for GDPR compliance. Hosting is via mysuitu.com CDN, ensuring moderate performance and good availability. Analytics and marketing tools including Google Analytics, Facebook Pixel, and LinkedIn Insight Tag are integrated for user tracking and advertising purposes. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms, reflecting a good baseline security posture. However, there is room for improvement by adding explicit security policies, incident response contacts, and updating legacy libraries like jQuery. No critical vulnerabilities or exposed sensitive data were detected. Privacy compliance is supported by a clear privacy policy and cookie management, though terms of service are absent. Overall, the website and business demonstrate a high level of professionalism and trustworthiness with a solid technical foundation. Strategic recommendations include enhancing security transparency, updating technical components, and publishing comprehensive legal documents to further strengthen compliance and user trust.

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

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

Dokonalý nájemník operates in the real estate sector focusing on rental property management with a unique selling proposition of guaranteed rent and full apartment care. Their business model targets landlords who prefer a hands-off approach to renting their properties. The company benefits from a strong partnership ecosystem including direct.cz, adol.cz, and flatino.cz, which supports their service offerings. Growth indicators include a well-maintained website with client testimonials and active social media presence. Revenue streams likely derive from rental management fees and loyalty bonuses. The company’s strategic positioning as an experienced rental specialist with a large portfolio enhances competitive advantage in the Czech market.

Security posture

The website exhibits a mature security posture with HTTPS enforced and cookie consent implemented, aligning with GDPR requirements. No security.txt or incident response information is published, which limits transparency in vulnerability reporting and incident handling. The use of an older jQuery version presents a minor security risk. No exposed sensitive data or known vulnerabilities were found in the HTML content. Security headers are not explicitly detected, suggesting an opportunity to improve defense-in-depth. Overall, the security maturity is good but could be enhanced by formalizing security policies and updating technical components.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Add incident response contact information such as security@ or abuse@ email addresses.
  3. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Upgrade jQuery and other JavaScript libraries to latest secure versions to mitigate vulnerabilities.
  5. Develop and publish terms of service to clarify legal relationships and responsibilities.

Technical notes

Notes

The website is built on the MySUITU CMS platform with integration of Google Maps API for address autocomplete and location services. It uses jQuery 1.11.0, which is outdated and should be upgraded. Hosting is via mysuitu.com CDN, providing moderate performance. The site is mobile optimized with responsive design and includes accessibility features at a basic level. SEO is supported by proper meta tags, Open Graph tags, and canonical URLs. Analytics and marketing tools are well integrated, including Google Analytics, Facebook Pixel, and LinkedIn Insight Tag. There is no evidence of technical debt beyond the legacy jQuery version. Overall, the technical infrastructure is solid with opportunities for modernization and security hardening.
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.
