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.

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

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

LUMIS operates as a small-sized travel agency within the hospitality sector, leveraging partnerships with multiple travel operators and service providers. Its business model revolves around selling packaged holidays, travel insurance, and ancillary services such as airport parking and flight compensation. The company targets Central European customers, particularly from the Czech Republic and neighboring countries, offering flights from various regional airports. The website's content and partner logos indicate a well-established network, enhancing competitive positioning. Revenue streams likely include commissions from travel bookings and insurance sales. The presence of a newsletter and callback form suggests active customer engagement strategies. Despite missing WHOIS data, the business appears operational and focused on growth within its niche.

Security posture

The website maintains a good security posture with enforced HTTPS and a comprehensive cookie consent mechanism aligned with GDPR requirements. The use of third-party analytics and marketing tools is transparent, with user consent managed appropriately. However, the lack of HTTP security headers such as Content-Security-Policy and absence of publicly available security or incident response policies represent gaps. No vulnerabilities or exposed sensitive data were detected in the HTML content. The missing WHOIS information raises concerns about domain registration transparency, which could impact trust. Overall, the security maturity is moderate to good, with recommendations to enhance header policies and publish security governance documents.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and preparedness.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Monitor domain WHOIS status and ensure registration information is accurate and publicly available to enhance trust.
  5. Enhance accessibility features and conduct periodic security assessments to maintain compliance and user safety.

Technical notes

Notes

The website is built on the CeSYS platform tailored for travel agencies, utilizing a modern tech stack including jQuery, Bootstrap, Select2, Slick Slider, and Moment.js. It integrates Google Analytics and Facebook SDK for tracking and marketing purposes. The site is mobile-optimized with responsive design and lazy loading for images, contributing to moderate performance. SEO is supported by appropriate meta tags and Open Graph data. However, the absence of some security headers and limited accessibility features suggest areas for technical improvement. Hosting details are not explicitly identified, and no CMS vulnerabilities were detected. Overall, the technical infrastructure supports a professional and functional user experience with room for security and accessibility enhancements.
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.
