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

4 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. 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.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 business operates in the hospitality sector, focusing on direct accommodation bookings in Czech mountain areas. Its competitive advantage lies in offering commission-free listings directly managed by property owners, fostering trust and cost savings for customers. The platform supports over 17,000 accommodations and multiple sister sites for neighboring countries, indicating a broad partnership ecosystem. Revenue likely derives from annual fees paid by accommodation providers. The target customers are tourists seeking affordable and direct booking options. The company maintains a consistent brand and leverages social media for outreach. Growth indicators include extensive content and user engagement features such as live cameras and weather updates.

Security posture

The website maintains a good security posture with HTTPS enforced and cookie consent implemented, aligning with GDPR requirements. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of some recommended security headers (e.g., HSTS, X-Frame-Options) suggests room for improvement. There is no public incident response or security policy information, which could enhance transparency and readiness. Overall, the security maturity is moderate to good, suitable for the business type but could benefit from further enhancements to protect user data and improve trust.

Recommendations

  1. Implement additional HTTP security headers such as Strict-Transport-Security, X-Content-Type-Options, and X-Frame-Options to strengthen security.
  2. Publish a clear security policy and incident response plan accessible to users to improve transparency and preparedness.
  3. Enhance accessibility features to improve usability for all users, including those with disabilities.
  4. Regularly audit third-party scripts and tracking tools to ensure compliance with privacy regulations and minimize tracking footprint.
  5. Consider adding structured data (JSON-LD) for business and product information to improve SEO and search engine visibility.

Technical notes

Notes

The website uses a modern front-end stack with Tailwind CSS and JavaScript, including deferred loading of scripts for performance. Google Analytics and Tag Manager are integrated for analytics and marketing. The site is mobile responsive with good SEO meta tags and keyword usage. No CMS was explicitly detected, suggesting a custom or proprietary platform. Performance is moderate with room for optimization. Accessibility is basic but could be improved. The site uses canonical links and meta viewport tags correctly. No critical technical debt or vulnerabilities were identified in the HTML content.
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.
