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

Fletstock s.r.o. is a Czech Republic based company specializing in real estate investment and professional property management services. The company offers a comprehensive suite of services including investment planning, property search, financing, renovation, rental, and ongoing management, targeting a broad audience from beginner investors to premium clients with larger portfolios. Their market position is strong within Prague, supported by client testimonials and case studies demonstrating consistent above-market returns. Technically, the website employs modern web technologies such as Bootstrap, jQuery, and various analytics and tracking tools, hosted on VAS Hosting infrastructure. Security posture is good with HTTPS enforced and GDPR compliance evident through cookie consent and privacy policy, though some security headers and incident response information are missing.

However, the WHOIS data shows an anomalous future domain creation date, which is likely a data error but slightly impacts trust assessment.

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

  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

      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

The company operates in the real estate sector with a focus on investment and property management in Prague. Their business model revolves around providing end-to-end services for property investors, including financial planning, property acquisition, renovation, and rental management. They maintain a selective investment approach, analyzing thousands of properties monthly and recommending only a small fraction for investment, which positions them as a quality-focused service provider. Their client base includes novice investors, experienced owners, and premium clients, indicating a diversified target market. The presence of partnerships, such as with Penta Real Estate and PixelBrothers for website development, suggests a solid ecosystem. The company emphasizes trust and professionalism, supported by extensive client reviews and case studies.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and secure form handling including GDPR consent. Multiple tracking and advertising scripts are used, but cookie consent mechanisms are in place to comply with privacy regulations. However, the absence of explicit security headers like Content-Security-Policy and lack of published security policies or incident response contacts are gaps. No vulnerabilities or exposed sensitive data were detected in the content. The WHOIS data anomaly does not directly impact website security but suggests a need for domain registration verification. Overall, the security posture is good but could be improved with additional headers and transparency.

Recommendations

  1. Implement and verify comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness for security incidents.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Review and correct WHOIS domain registration data to ensure consistency and trustworthiness.
  5. Continue maintaining GDPR compliance and enhance user privacy controls for tracking and data collection.

Technical notes

Notes

The website uses a modern and well-supported technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, Swiper for sliders, AOS for animations, and Plyr for media handling. Google Fonts are used for typography. The site is hosted on VAS Hosting as indicated by the nameservers. Performance is moderate with asynchronous loading of analytics and tracking scripts to reduce blocking. The site is mobile optimized with good accessibility features and SEO meta tags including Open Graph for social sharing. No CMS was explicitly detected, suggesting a custom or proprietary solution. Technical debt appears low, but security header implementation could be improved. Overall, the technical infrastructure supports a professional and user-friendly experience.
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.
