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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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';…

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

HYPOX occupies a niche position in the Czech real estate market, focusing on digital tools for property valuation and portfolio management. Its business model revolves around providing free and paid online services to property owners and investors, leveraging data analytics and mapping technologies. The company benefits from partnerships with analytics and marketing platforms such as Microsoft Clarity, Google Tag Manager, and Facebook Pixel to optimize user engagement and marketing effectiveness. The absence of large-scale certifications or security policies suggests a small to medium enterprise with room for maturity in compliance and security governance. The company’s growth potential lies in expanding its service offerings and enhancing trust through transparent security and privacy practices.

Security posture

The website demonstrates a good security posture with enforced HTTPS, comprehensive security headers, and a cookie consent mechanism compliant with GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a publicly available security policy or incident response contact reduces transparency in security governance. The use of multiple third-party tracking scripts introduces a moderate level of user tracking, which is managed through consent banners. There is an opportunity to improve security maturity by publishing vulnerability disclosure policies and incident response procedures. Overall, the security posture is adequate for the business scale but could be enhanced for higher assurance.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Establish and publicize an incident response contact or procedure to improve transparency.
  3. Implement a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to meet broader compliance standards.
  5. Regularly review and audit third-party scripts to mitigate potential security risks.

Technical notes

Notes

HYPOX utilizes a modern technology stack including React and Next.js frameworks, with Material-UI for UI components, hosted on AWS infrastructure. The website is mobile optimized and employs performance best practices such as image preloading and asynchronous script loading. SEO is supported by proper meta tags and canonical links. Accessibility is basic but could be improved. The site integrates multiple analytics and marketing tools, balancing functionality with privacy compliance via Cookiebot. Technical risks are minimal, but reliance on several third-party scripts necessitates ongoing security monitoring. Overall, the technical implementation is robust and aligns with contemporary web development standards.
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.
