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

Altclub is an established Czech online education platform specializing in cryptocurrency and trading courses. Founded in 2009, it offers a range of courses from beginner to master levels, including a comprehensive Trader Challenge program. The platform targets individuals interested in learning about cryptocurrencies and trading, providing video lessons, tips, and practical trading education. It positions itself as the leading online academy in its niche within the Czech market, supported by endorsements from educational authorities and positive student testimonials. Technically, the website employs a modern tech stack including jQuery, Google Analytics, Facebook Pixel, Hotjar, and Google reCAPTCHA, ensuring interactive and trackable user experiences. However, some security best practices such as DNSSEC and security headers are missing, and no cookie consent mechanism is present despite GDPR compliance claims. Overall, the site is professionally designed, mobile-optimized, and trustworthy, with a good balance of content quality and business credibility.

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

9 findings rated critical or high. Fix these first.

  1. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Altclub operates a direct-to-consumer online education business model, monetizing through paid courses and memberships. Its competitive advantage lies in its comprehensive course offerings tailored to various skill levels and its strong local market presence in the Czech Republic. The platform leverages endorsements from reputable educational institutions to build trust. The target customer segment includes crypto enthusiasts and traders ranging from novices to professionals. The presence of multiple course tiers and a challenge program indicates a growth-oriented approach to customer engagement and retention. The website's integration with major ad networks and tracking tools suggests active marketing and user behavior analysis to optimize conversions. No clear partnerships or subsidiaries were identified, and the business appears to be a small-sized independent entity.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and use of Google reCAPTCHA to protect forms from abuse. However, the absence of DNSSEC and security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces its defense-in-depth capabilities. No explicit security or incident response policies are published, and no dedicated security contact channels are provided. The forms include client-side validation but no visible advanced security measures. The lack of a cookie consent mechanism may expose the site to GDPR compliance risks. Overall, while no critical vulnerabilities were detected, improvements in DNS security, HTTP headers, and privacy compliance are recommended to enhance security maturity.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  2. Implement essential security headers (CSP, X-Frame-Options, X-Content-Type-Options) to mitigate common web attacks.
  3. Add a cookie consent banner/mechanism to comply fully with GDPR requirements.
  4. Publish a formal security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve user trust.

Technical notes

Notes

The website uses a combination of modern JavaScript libraries and frameworks including jQuery, Slick Carousel, Remodal, Chart.js, GSAP, ScrollMagic, and Video.js, providing rich interactive features and multimedia content. Google Tag Manager, Google Analytics, Facebook Pixel, and Hotjar are integrated for analytics and user behavior tracking. The backend likely uses the Nette Framework, a PHP framework popular in Czech Republic. Hosting is provided by Gransy, s.r.o., a Czech registrar and hosting provider. The site is mobile-optimized with responsive design and uses Google Fonts for typography. Performance is moderate with asynchronous loading of scripts and CDN usage for some assets. Accessibility features are basic, with room for improvement. SEO is supported by proper meta tags, Open Graph, and Twitter Card metadata. Overall, the technical infrastructure is solid but could benefit from enhanced security configurations and privacy controls.
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.
