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

ŠumavaNet.CZ operates a regional tourism and accommodation portal focused on the Šumava region and surrounding areas in the Czech Republic. The website provides a comprehensive catalog of accommodations, tourism tips, event calendars, and media galleries, targeting tourists, local businesses, and residents interested in the region. It holds a recognized position as a regional information source with partnerships and awards supporting its credibility. Technically, the site uses common web technologies including jQuery, Google Analytics, and cookie consent scripts, with a moderate performance and good mobile optimization. Security posture is adequate with HTTPS enabled and cookie consent implemented, though security headers are not evident and could be improved. The absence of WHOIS data reduces transparency but does not detract significantly from the site's legitimacy given the detailed contact information and active social media presence. Overall, the website is professional, trustworthy, and compliant with privacy regulations, serving as a valuable resource for its audience.

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

5 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 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';…

  2. 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

      SSL Certificate Expires Soon

      SSL certificate expires in 19 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 portal's business model centers on advertising and listing services for accommodation providers and local businesses, supplemented by media content publishing. It targets tourists and visitors seeking lodging and activities in the Šumava region, leveraging partnerships with regional organizations. The site demonstrates consistent branding and content quality, with a focus on regional culture, events, and tourism infrastructure. Revenue likely derives from advertising placements and promotional partnerships. The presence of multiple contact channels and a contact form facilitates business inquiries and advertising sales. The portal's market position is that of a specialized regional information hub with a loyal audience and recognized reputation.

Security posture

The website exhibits a basic to moderate security maturity level. HTTPS is properly implemented, and a cookie consent mechanism aligns with GDPR requirements. However, the lack of visible security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. There is no evidence of a dedicated security policy, incident response contacts, or vulnerability disclosure program, which are recommended for enhanced security posture. The use of third-party scripts like Google Analytics and AddThis introduces typical tracking risks but is managed with user consent. Overall, the site maintains a reasonable security baseline appropriate for its business type but should enhance security controls and transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to harden the site against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Conduct regular audits of third-party scripts and dependencies to identify and mitigate vulnerabilities.
  4. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.
  5. Maintain and update privacy and cookie policies regularly to ensure ongoing GDPR compliance and user trust.

Technical notes

Notes

The website uses a traditional web stack with jQuery and various Google services for analytics and search. It employs Font Awesome for icons and a cookie consent solution for privacy compliance. The site is moderately performant with good mobile responsiveness and SEO optimization. However, no modern frameworks or CMS platforms were detected, suggesting a custom or legacy implementation. Hosting provider details are not evident. The site could benefit from modernization efforts including adoption of modern JavaScript frameworks, improved accessibility, and enhanced security configurations. Technical debt appears moderate, with opportunities to improve performance and security without major overhaul.
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.
