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

TKR Jašek s.r.o. operates the VALACHNET.cz portal, providing regional telecommunications services including internet, television, telephone, mobile, and hosting primarily in the Valašsko region of the Czech Republic. The company has a long-standing presence since 1990 and targets residential and business customers within its service area. The website reflects a regional ISP with a focus on customer engagement and service announcements. Technically, the website uses a traditional tech stack with jQuery and jQuery UI libraries, serving content over HTTPS. While the site is functional and content-rich, it lacks advanced security headers and modern privacy compliance features such as a cookie consent mechanism. The site is moderately optimized for performance and accessibility but could benefit from modernization. Security posture is adequate with HTTPS enabled and no visible sensitive data exposure, but the absence of security headers and vulnerability disclosures indicates room for improvement. The lack of WHOIS data reduces domain trustworthiness, though the website content and business information appear consistent and legitimate. Overall, the site presents a trustworthy regional ISP with good business credibility but requires enhancements in security best practices and privacy compliance to align with modern standards.

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

8 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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 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

The company is positioned as a small regional telecommunications provider with a diversified service portfolio including internet, TV, voice, mobile, and hosting. Its competitive advantage lies in local market knowledge and long-term customer relationships. Revenue streams likely come from subscription services and value-added offerings such as FixProTV. The partnership ecosystem includes cultural organizations and industry associations, enhancing community presence. Growth indicators include service upgrades and new offerings. The business model focuses on direct customer service and regional infrastructure investment.

Security posture

The current security maturity is moderate. HTTPS is enforced, but the absence of key security headers such as Content-Security-Policy and HSTS reduces protection against common web attacks. No vulnerability disclosures or incident response contacts are published, indicating limited transparency. Forms are present but lack visible CSRF protections. Privacy compliance is minimal, with no explicit GDPR statements or cookie consent mechanisms. The company should prioritize implementing security headers, enhancing privacy policies, and establishing incident response protocols to improve security culture and readiness.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and HSTS.
  2. Publish clear privacy and cookie policies with GDPR compliance statements and implement a cookie consent banner.
  3. Establish and publicize an incident response contact channel and vulnerability disclosure policy.
  4. Upgrade JavaScript libraries to latest versions and audit for vulnerabilities.
  5. Enhance website accessibility and mobile responsiveness to improve user experience.

Technical notes

Notes

The website is built on a classic web stack using jQuery and jQuery UI, with CSS and HTML served in windows-1250 charset for Czech language support. The site loads multiple CSS files and JavaScript libraries asynchronously, including Google Custom Search integration. Performance is moderate with no evident advanced optimization techniques. The site lacks a modern CMS or framework indication. Hosting provider details are not disclosed. The site is functional but could benefit from modernization to improve speed, mobile optimization, and security posture.
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.
