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

The website www.veleton.cz serves as the online platform for the largest Czech festival focused on construction, housing, and heating, scheduled for January 2026. It offers free registrations, expert lectures, recorded presentations, and consultations, targeting Czech-speaking individuals interested in building and energy-saving technologies. The platform is well-positioned in the Czech market as a leading online event for the construction sector, supported by numerous industry partners and sponsors. Technically, the site employs modern web technologies including jQuery, FancyBox, Slick Carousel, and integrates multiple analytics and marketing tools such as Google Tag Manager, Microsoft Clarity, and Facebook Pixel. The site is mobile-optimized with responsive design and includes cookie consent mechanisms compliant with GDPR. Performance is moderate with good SEO and basic accessibility features. From a security perspective, the site uses HTTPS and cookie consent but lacks explicit security headers and dedicated security policy pages. No vulnerabilities or exposed sensitive data were detected. The WHOIS data is unavailable, likely due to privacy protection, but the website's professional appearance and trust signals indicate legitimacy. Overall, the website presents a low-risk profile with good business credibility and privacy compliance. Strategic improvements in security headers and accessibility could enhance its posture further.

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 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

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 business operates as an online event platform specializing in the construction and housing sector within the Czech Republic. It leverages a free registration model to attract attendees and monetizes through exhibitor partnerships and sponsorships. The platform's extensive partner ecosystem and testimonials indicate strong industry relationships and market acceptance. The focus on energy-saving and heating technologies aligns with current market trends, positioning the business for growth in the digital event space. The absence of direct contact details on the main page suggests a focus on online engagement rather than direct sales. The company targets a medium-sized audience of professionals and consumers interested in construction innovations and energy efficiency. The business model is scalable and adaptable to future online events, with potential for expansion into related sectors.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced, and privacy compliance is evident through cookie consent and GDPR policy pages. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. No signs of vulnerabilities or exposed sensitive data were found in the HTML content. The use of multiple third-party analytics and marketing scripts introduces a moderate tracking footprint, which is managed through consent mechanisms. Incident response and security policy documentation are not publicly available, indicating an area for improvement. The lack of WHOIS data limits domain trust verification but is mitigated by the professional site presentation and partner endorsements. Overall, the site is secure for its purpose but would benefit from enhanced security controls and transparency.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response information to improve transparency and trust.
  3. Enhance accessibility features to meet higher standards and improve user experience for all visitors.
  4. Regularly audit and update third-party scripts to minimize security risks from external dependencies.
  5. Consider providing clear company contact information to improve business credibility and user trust.

Technical notes

Notes

The website is built on a modern JavaScript stack with jQuery, FancyBox, and Slick Carousel for UI components. It integrates multiple analytics and marketing tools such as Google Tag Manager, Microsoft Clarity, and Facebook Pixel, indicating a mature digital marketing approach. The site uses responsive design with Google Fonts and asynchronous script loading to optimize performance. However, no CMS or hosting provider information is explicitly detected. Performance is moderate with room for improvement in loading speed and accessibility. The site structure and meta tags support good SEO practices. Technical debt appears low, but security header implementation and accessibility enhancements are recommended to reduce risks and improve compliance.
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.
