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

NetDeluxe s.r.o. operates as a local internet and television service provider primarily serving the South Moravia region in the Czech Republic. The company offers stable and fast internet connections alongside smart TV services with multiple programs and features, targeting both residential and business customers. The website reflects a professional and consistent brand presence with clear service offerings and a focus on competitive pricing within its local market. Technically, the site is built on WordPress with modern libraries such as jQuery, Bootstrap, and Leaflet.js, and integrates Google Tag Manager for analytics. The site is mobile-optimized and SEO-friendly, leveraging Yoast SEO for metadata and structured data. Security-wise, the site uses HTTPS and avoids exposing sensitive data, but lacks some security headers and formal security policies. The absence of WHOIS data reduces domain trustworthiness, though the website content and social media presence support legitimacy. Privacy compliance is partial, with a cookie consent mechanism but no explicit privacy or terms of service pages. Overall, the site is functional and professional but could improve transparency and security documentation.

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. 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

      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

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

NetDeluxe positions itself as a small regional ISP with a focus on the South Moravia area, offering internet and smart TV services. Its competitive advantage lies in local presence, fast installation, and affordable pricing. The business model is service-based, targeting households and businesses needing reliable internet and television. The company maintains active social media profiles on Facebook and Instagram, enhancing customer engagement. There is no evidence of partnerships or subsidiaries from the provided data. The website content and technical setup indicate a mature digital presence but limited compliance documentation. Growth potential exists through expanding service areas and enhancing online trust signals. The lack of WHOIS transparency is a concern but may be due to privacy restrictions or registry policies.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and no visible exposure of sensitive information. However, it lacks important security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection, which are recommended to mitigate common web attacks. There is no published security policy or incident response contact information, and no vulnerability disclosure or security.txt file is present. The use of third-party scripts like Google Tag Manager and Smartsupp chat introduces potential tracking and privacy considerations. No known vulnerabilities or malware indicators were detected in the HTML content. To improve security maturity, the company should implement recommended HTTP headers, publish security policies, and establish clear incident response channels.

Recommendations

  1. Implement comprehensive privacy and terms of service pages to improve compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against web attacks.
  3. Publish a security policy and incident response contact information to demonstrate security readiness.
  4. Consider creating a vulnerability disclosure policy and security.txt file to encourage responsible reporting.
  5. Verify and update WHOIS registration data to improve domain trustworthiness and transparency.

Technical notes

Notes

The website is built on WordPress CMS version 6.6.2, using a combination of popular JavaScript libraries including jQuery, Bootstrap for responsive design, Slick Slider for carousels, Magnific Popup for modals, Justified Gallery for image layouts, and Leaflet.js for interactive maps. SEO is managed via Yoast SEO plugin, which provides structured data in JSON-LD format and Open Graph metadata for social sharing. Google Tag Manager is used for analytics and marketing tags, and a cookie consent banner is implemented for GDPR compliance. The site loads external fonts from Google Fonts and uses CDN-hosted scripts for legacy browser support. Performance appears moderate with asynchronous script loading and lazy loading of images. Accessibility is basic with some ARIA roles and semantic HTML, but could be improved. Hosting provider details are not disclosed. Overall, the technical stack is modern and well-integrated but could benefit from enhanced security configurations and more comprehensive compliance documentation.
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.
