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

Happy Divers s.r.o. operates as a specialized diving center and school based in Prague, Czech Republic. The company offers a comprehensive range of diving courses for beginners and advanced divers, sells high-quality diving equipment from renowned brands, provides equipment servicing, and organizes diving trips domestically and internationally. Their SSI Diamond Center certification underscores their recognized expertise and quality in the diving education sector. The website is well-structured, providing clear navigation and relevant content tailored to diving enthusiasts and customers seeking diving-related services and products. Technically, the website employs a traditional web stack with jQuery and related plugins for UI and interactivity, alongside modern tools like Google Tag Manager and Google Analytics for marketing and analytics. The site is mobile-optimized and includes a cookie consent mechanism compliant with GDPR, reflecting a mature approach to privacy and user experience. However, some technical debt is noted with the use of older jQuery versions and absence of explicit security headers. From a security perspective, the site benefits from HTTPS encryption and a robust cookie consent framework. No critical vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data limits domain trust assessment, but the visible business information and certifications support legitimacy. Overall, the site demonstrates a solid security posture with room for improvements in security headers and updated libraries. The overall risk profile is moderate-low, with recommendations focusing on enhancing security headers, updating third-party libraries, and adding legal documents such as terms of service. These steps will strengthen compliance, trust, and resilience against emerging threats.

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

  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

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

Happy Divers holds a strong position in the local diving education and retail market, leveraging its SSI Diamond Center certification to differentiate itself. The business model integrates service delivery (courses, trips, equipment servicing) with retail sales (diving gear and accessories), creating multiple revenue streams. Their target customers include novice divers, experienced divers seeking advanced training, and diving equipment buyers. The company maintains active engagement through social media and newsletter subscriptions, indicating a focus on community building and customer retention. Partnerships with e-commerce platforms like Scubashop.cz enhance their market reach. Growth indicators include regularly scheduled courses and travel offers, suggesting steady operational activity. Strategic observations highlight the importance of maintaining digital security and compliance to protect customer trust and business continuity.

Security posture

The website exhibits a mature security posture with HTTPS enforced and a comprehensive cookie consent mechanism aligned with GDPR requirements. The absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is a notable gap that could expose the site to certain web-based attacks. The use of an outdated jQuery version presents a potential vulnerability vector if not regularly patched. No signs of data leakage, malware, or phishing were found. Incident response and security policy information are not publicly disclosed, which could hinder rapid response in case of security events. Overall, the site is secure for typical user interactions but would benefit from enhanced security controls and transparency.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Update jQuery and other third-party libraries to their latest stable versions to reduce risk from known vulnerabilities.
  3. Publish a terms of service page to improve legal compliance and user trust.
  4. Consider adding explicit security policy and incident response contact information to enhance transparency and preparedness.
  5. Conduct regular security audits and penetration testing to proactively identify and remediate vulnerabilities.

Technical notes

Notes

The website uses a classic web technology stack centered around jQuery 1.11.1 and associated plugins for UI components and interactivity. It integrates Google Tag Manager and Google Analytics for marketing and analytics purposes, alongside Facebook SDK for social media integration. The site is mobile responsive with good SEO practices including meta tags and Open Graph data. Performance is moderate, likely influenced by the use of older libraries and multiple external scripts. Accessibility is basic but could be improved with ARIA roles and better semantic markup. No CMS is explicitly detected, suggesting a custom or static site architecture. Hosting provider details are not discernible from the provided data. Overall, the technical implementation is solid but would benefit from modernization and enhanced accessibility.
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.
