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

ha-vel internet s.r.o. is a Czech telecommunications company operating a major data network serving over 50 towns and cities. The company offers a broad range of services including data, IT, voice, leased lines, IP connectivity, video conferencing, and mobile telephony under the ha-loo brand. Their market position is supported by partnerships with major telecom operators such as Vodafone and T-Mobile, and they target a diverse customer base including corporations, public administration, wholesale providers, and households. The website content is professional and well-structured, reflecting a medium-sized enterprise with a solid presence in the Czech telecommunications sector. Technically, the website is built on Drupal CMS with legacy jQuery libraries and includes modern features such as a cookie consent banner compliant with GDPR. The site is mobile optimized and provides a good user experience, although some technical improvements could be made, such as updating JavaScript libraries and enhancing accessibility. The hosting provider is not explicitly identified, but the site uses HTTPS with a good SSL configuration. From a security perspective, the site enforces HTTPS and includes cookie consent mechanisms, but lacks visible security headers and explicit security policies. The presence of a CSIRT page indicates some level of incident response readiness. No critical vulnerabilities or exposed sensitive data were detected. WHOIS data is unavailable due to EURid privacy policies, but the domain appears legitimate and consistent with the business claims. Overall, ha-vel.eu presents a trustworthy and professional telecommunications service provider with a solid digital presence. Strategic improvements in security headers, updated libraries, and enhanced privacy disclosures would further strengthen their security posture 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

3 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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

ha-vel internet s.r.o. holds a significant position in the Czech telecommunications market, offering a comprehensive portfolio of network and communication services. Their business model focuses on providing high-quality, scalable solutions to demanding customers across multiple sectors. The company leverages partnerships with major telecom operators to enhance service reliability and reach. Revenue streams likely include wholesale network access, leased lines, IT services, voice services, and mobile telephony. The website highlights customer references and case studies, indicating a focus on customer satisfaction and business development. Growth indicators include service expansion and new offerings such as ha-fi and ha-loo mobile. The partnership ecosystem includes major players like Vodafone, T-Mobile, and Student Agency, reinforcing market credibility. Operationally, the company demonstrates a commitment to quality and security, although some modernization opportunities exist in their digital infrastructure.

Security posture

The security posture of ha-vel.eu is moderate with key strengths including enforced HTTPS, cookie consent compliance, and an incident response page (CSIRT) indicating organizational awareness of security incidents. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security hardening of the web presence. The use of outdated jQuery versions may expose the site to known vulnerabilities if not properly patched. No exposed sensitive data or critical vulnerabilities were detected in the HTML content. Privacy compliance is addressed through cookie policies and GDPR-aligned disclosures. Incident response readiness is suggested but contact channels for security issues are not explicitly provided. Overall, the site would benefit from enhanced security headers, updated libraries, and a published vulnerability disclosure policy to improve trust and resilience.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to harden the website against common attacks.
  2. Upgrade JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  3. Publish explicit security and privacy policies, including a vulnerability disclosure policy or security.txt file, to enhance transparency and compliance.
  4. Enhance accessibility features to improve usability for all users and meet modern standards.
  5. Provide clear and multiple contact channels for security incident reporting and data protection officer information to strengthen incident response and GDPR compliance.

Technical notes

Notes

The website is built on Drupal CMS with legacy jQuery 1.12.4 and jQuery UI 1.10.2 libraries, indicating a somewhat dated technology stack. The site uses external CDNs for common libraries and includes a cookie consent script from cookie-bar.eu. Performance is moderate with no explicit indicators of slow loading but could be improved by updating libraries and optimizing assets. Mobile optimization is good with responsive meta tags and CSS. SEO is basic with standard meta tags but no Open Graph or JSON-LD structured data detected. Accessibility is basic with skip links and some ARIA roles but could be enhanced. Hosting provider details are not disclosed. Overall, the technical infrastructure is functional but would benefit from modernization and security hardening.
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.
