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

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

Travelio.sk operates as a niche travel agency focusing on German and Austrian travel packages for Slovak customers, leveraging partnerships with major European travel operators. Its competitive advantage lies in direct representation and a comprehensive online booking platform with detailed filtering options. Revenue streams likely include commissions from travel bookings and ancillary services such as insurance and car rentals. The target customer segment is Slovak-speaking travelers seeking reliable and convenient vacation options abroad. The company maintains a strong partnership ecosystem, including well-known travel agencies and airlines. Growth indicators include a broad destination portfolio and active marketing via Google and Facebook. The business demonstrates a clear market position as a trusted expert in its domain.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and good SSL configuration. Cookie consent and privacy policies are implemented, supporting GDPR compliance. The use of reputable analytics and marketing tools is balanced with user consent mechanisms. However, the absence of a published security policy and incident response contacts limits transparency. Security headers such as Content-Security-Policy and X-Frame-Options are not explicitly detected, representing an area for improvement. No vulnerabilities or exposed sensitive data were found in the HTML content. Overall, the security posture is solid but could benefit from enhanced header policies and formal security documentation.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  3. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Maintain transparency in data retention policies and provide clear user options for data management.

Technical notes

Notes

The website is built on a custom travel agency system (CeSYS) with a modern front-end stack including jQuery, Bootstrap, and Slick Carousel. It integrates multiple third-party analytics and marketing tools such as Google Analytics, Facebook Pixel, Hotjar, and Google Tag Manager, all managed with cookie consent. The site is mobile-optimized and features comprehensive search and booking forms with advanced filtering capabilities. Performance is moderate, with lazy loading of images and asynchronous script loading. Technical debt appears minimal, but opportunities exist to improve security headers and accessibility compliance. Hosting details are not explicitly identified but appear stable given the CDN usage for static assets.
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.
