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

Dobrý web is a Czech-based educational platform specializing in digital marketing and UX training, offering a variety of online and bespoke courses. The company has a strong market presence with over 14 years of experience and a high satisfaction rate among participants. Their business model focuses on e-learning and tailored corporate training, supported by a parent company Sherpas, s.r.o., a digital agency. The website is professionally designed with clear navigation and rich content, targeting individuals and companies seeking to improve their digital marketing skills. Technically, the site uses modern web technologies including Google Analytics, Google Tag Manager, and reCAPTCHA for security. The site is mobile-optimized and SEO-friendly, with structured data enhancing search visibility. Security posture is good with HTTPS and form protections, though some security headers and policies could be improved. Privacy compliance is basic with cookie consent but lacks a clear privacy policy page. WHOIS data is missing, which reduces domain trustworthiness, but the overall business credibility and content quality are high. Recommendations include publishing a privacy policy, security policy, and improving security headers to enhance 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

    • 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

  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

      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

Dobrý web operates in the education sector, focusing on digital marketing and UX training primarily in the Czech Republic. The company leverages a strong partnership with Sherpas, a digital agency, to provide expert-led courses. Their offerings include live and recorded e-learning programs, targeting professionals and businesses. The business benefits from a solid reputation, demonstrated by testimonials and satisfaction guarantees. Revenue streams likely include course fees and subscriptions. The partnership ecosystem includes media partners and a parent company, enhancing market reach. Growth indicators include a broad course catalog and online presence. Strategic observations suggest potential for expanding privacy and security transparency to meet evolving compliance standards.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA to protect forms, and cookie consent mechanisms. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No public security policy or incident response information is available, which could hinder transparency and trust. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site would benefit from publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting. Overall, the security maturity is good but can be enhanced with additional headers and documented policies.

Recommendations

  1. Publish a comprehensive privacy policy page to improve GDPR compliance and user trust.
  2. Implement and configure security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Create and publish a security policy and incident response information to enhance transparency.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible security reporting.
  5. Verify and update WHOIS domain registration information to improve domain legitimacy and trust.

Technical notes

Notes

The website uses a modern technology stack including Google Analytics, Google Tag Manager, Google reCAPTCHA, and the Bulma CSS framework. The presence of Nette framework form validation indicates a PHP backend. The site is mobile-optimized with good accessibility and SEO practices, including structured data for organization and events. Performance is moderate with asynchronous loading of scripts. No common CMS like WordPress or Joomla was detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the content. Technical risks are low, but the absence of some security headers and missing WHOIS data are notable. Opportunities exist to improve security posture and privacy transparency to align with best practices.
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.
