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

INTERNEXT 2000, s.r.o. is a regional Czech internet service provider offering broadband internet, TV, VoIP telephony, and hosting services primarily in cities such as Zlín, Otrokovice, Uherské Hradiště, and Vsetín. The company emphasizes affordable, high-speed internet with packages up to 1 Gb/s and has been operating for approximately 29 years, indicating a well-established market presence. Their website targets residential and small business customers in the Czech Republic, providing clear service offerings and customer support channels. Technically, the website is built on WordPress with modern JavaScript libraries and integrates Google Analytics and Tag Manager for tracking. It uses HTTPS with good security headers and a cookie consent mechanism compliant with GDPR. The site is mobile-optimized and provides a good user experience with clear navigation and professional design. However, some accessibility features could be improved. From a security perspective, the site follows best practices such as enforcing HTTPS, implementing security headers, and avoiding exposure of sensitive data. No critical vulnerabilities or suspicious scripts were detected. Privacy compliance is strong with explicit cookie consent and a comprehensive privacy policy. However, the site lacks a published security policy or incident response contact information. Overall, the website and business appear legitimate and trustworthy, with a solid security posture and compliance framework. The absence of WHOIS data due to privacy protection is common and justified for this business type. Strategic recommendations include publishing a security policy, incident response details, and enhancing accessibility to further improve trust and compliance.

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

7 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

  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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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

INTERNEXT operates as a medium-sized ISP focused on regional markets in the Czech Republic, leveraging nearly three decades of experience. Their competitive advantage lies in offering high-speed internet at affordable prices with bundled TV and telephony services. The business model is subscription-based with multiple service tiers. The company maintains a partnership ecosystem including data center providers and TV service platforms, enhancing their service portfolio. Growth indicators include the promotion of 1 Gb/s internet and customer support availability. The website content and structure support lead generation and customer engagement effectively.

Security posture

The website demonstrates a mature security posture with HTTPS enforcement, comprehensive security headers, and no visible sensitive data leaks. Cookie consent and privacy policies align with GDPR requirements. The use of third-party analytics is managed with consent mechanisms. However, the lack of a public security policy and incident response contacts represents a compliance gap. No vulnerabilities or outdated libraries were detected. The security culture appears adequate but could benefit from transparency improvements and formal vulnerability disclosure mechanisms.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Add incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file.
  4. Enhance website accessibility features to meet higher standards.
  5. Regularly review and update third-party scripts and plugins to mitigate potential vulnerabilities.

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.
