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

Periscope Travel s.r.o. operates a professional travel agency website specializing in Scandinavian and northern European destinations, as well as worldwide travel tours. The company has a strong market presence with over 33 years of experience, offering a wide range of travel services including organized tours, cruises, travel insurance, and ferry tickets. The website is well-structured, content-rich, and targets travelers interested in niche northern European and global destinations. Technically, the site uses modern analytics and marketing tools such as Google Analytics, Google Tag Manager, and retargeting pixels, indicating a mature digital marketing strategy. The website is mobile optimized and provides a good user experience with clear navigation and comprehensive search filters. Security-wise, the site enforces HTTPS and cookie consent mechanisms but lacks visible security headers, which could be improved. The absence of WHOIS data is a concern but does not outweigh the professional presentation and compliance indicators. Overall, the site is trustworthy and professionally maintained, with room for technical security 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

10 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

      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 X-Frame-Options header

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 holds a solid position in the travel and hospitality sector, focusing on specialized travel experiences in Scandinavia and northern Europe, which differentiates it from generalist travel agencies. Its business model revolves around curated travel packages, guided tours, and related travel services. The presence of detailed customer testimonials, event announcements, and a team section indicates a customer-centric approach and active community engagement. The company targets middle to upper-middle-class travelers seeking unique travel experiences. Its marketing ecosystem includes partnerships with major ad networks and social media platforms, supporting growth and customer acquisition. The lack of publicly available WHOIS data is a minor risk factor but likely due to privacy settings or registry policies.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS and cookie consent management reflecting GDPR compliance. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces the overall security maturity. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site uses third-party scripts for analytics and advertising, which should be regularly audited to prevent supply chain risks. There is no explicit incident response or security policy information available, which could be improved to enhance transparency and readiness. Overall, the security posture is adequate for a travel agency website but can benefit from implementing additional HTTP security headers and publishing a security policy.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and customer trust.
  3. Regularly audit and update third-party scripts and libraries to mitigate supply chain vulnerabilities.
  4. Enhance accessibility features to comply with recognized standards and improve user experience for all visitors.
  5. Consider publishing WHOIS data or ensuring domain registration information is accessible to improve trust and legitimacy perception.

Key observations

  1. Website is fully accessible with rich content and interactive features.
  2. No WAF or blocking mechanisms detected.
  3. WHOIS data is missing or inaccessible, which is a concern but not definitive of illegitimacy.
  4. Strong GDPR and privacy compliance indications.
  5. Comprehensive travel service offerings with detailed search and filtering.
  6. Multiple social media and video channel integrations.
  7. Use of multiple advertising and analytics services indicates active marketing.
  8. No security headers detected in HTML source; potential area for improvement.
  9. Website uses legacy charset windows-1250 but is otherwise modern and responsive.
  10. No explicit security policy or incident response information found.
Technical notes

Notes

The website uses a traditional HTML structure with JavaScript for interactivity and integrates multiple Google services for analytics and advertising. The charset is windows-1250, which is less common today but appropriate for Czech language content. The site is mobile responsive with a clear navigation menu and advanced search filters for travel packages. Performance appears moderate with asynchronous loading of analytics scripts. No CMS or hosting provider information is explicitly detected. The site could benefit from modernizing some technical aspects such as adopting UTF-8 charset and implementing progressive web app features. Overall, the technical infrastructure supports the business needs but has room for modernization and improved security hardening.
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.
