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

Dalekohledy.cz is a Czech-based specialized retailer focusing on astronomical telescopes, binoculars, observation telescopes, microscopes, and related accessories. The company, AiVision, s.r.o., operates both an e-commerce platform and a physical store serving customers primarily in the Czech Republic and Slovakia. The website presents a professional and well-structured interface with clear navigation and a comprehensive product catalog. The business targets astronomy enthusiasts and amateur astronomers, offering products from reputable brands such as Baader, Celestron, Sky-Watcher, and Swarovski. Technically, the site employs modern web technologies including Bootstrap, jQuery, and various UI enhancement libraries, ensuring a responsive and user-friendly experience. However, some minor technical issues such as PHP warnings and lack of security headers were observed. Security posture is adequate with HTTPS enforced and secure login mechanisms, but improvements are recommended in cookie consent and security header implementation. The absence of WHOIS data limits domain trust assessment, but the website content and business information appear legitimate and consistent with a specialized retail operation. Overall, the site is well-positioned in its niche with room for security and privacy compliance enhancements.

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. 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

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 company operates in the retail sector specializing in astronomy and optical equipment. Its business model combines e-commerce with a physical storefront, targeting a niche market of astronomy hobbyists and professionals in the Czech and Slovak regions. The website showcases a broad product range with detailed categorization and brand representation, indicating a strong market position as a specialist retailer. The presence of a blog and news section suggests active engagement with the community and ongoing marketing efforts. The lack of visible social media links or phone contacts on the main page may limit direct customer engagement channels. The company appears to maintain a focused and consistent brand identity with professional content and trust signals such as clear contact forms and business descriptions.

Security posture

The website enforces HTTPS and uses secure AJAX-based login forms, which are positive security practices. However, the absence of key security headers like Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. The presence of PHP warnings in the HTML output indicates potential information leakage and should be addressed to avoid exposing internal server details. Cookie consent mechanisms are present in code but commented out, suggesting incomplete GDPR compliance. No incident response or vulnerability disclosure information is available, which could be improved to enhance security transparency. Overall, the security posture is moderate but requires attention to headers, error handling, and privacy compliance to strengthen defenses.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  2. Fix PHP warnings and errors to prevent information leakage and improve code quality.
  3. Activate and enhance cookie consent mechanisms to ensure GDPR compliance and user privacy.
  4. Publish clear security policy and incident response contact information to improve transparency and trust.
  5. Consider adding visible contact phone numbers and social media links to improve customer engagement and credibility.

Technical notes

Notes

The website uses a modern frontend stack with Bootstrap for responsive design, jQuery and jQuery UI for interactivity, and additional libraries like Splide.js for sliders and AOS for animations. The site appears to be custom-built or uses a proprietary CMS, as no common CMS signatures were detected. Performance is moderate with asynchronous script loading and optimized assets. Mobile optimization is good with responsive menus and layouts. Accessibility features are basic but present. SEO is supported by proper meta tags and structured navigation. Minor technical debt is indicated by PHP warnings and incomplete cookie consent implementation. Hosting provider details are not discernible from the HTML content.
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.
