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

Invia.sk is a leading online travel agency in Slovakia specializing in the sale of travel packages and last-minute vacations from multiple travel operators. The website targets a broad audience seeking holiday bookings primarily in popular European and Mediterranean destinations. Technically, the site employs modern web technologies including JavaScript frameworks, CDN delivery, and advanced analytics and error tracking tools such as Google Analytics, Hotjar, and Sentry. The presence of a comprehensive cookie consent mechanism and privacy policy indicates a good level of GDPR compliance. Security posture is strong with HTTPS enforced and no visible vulnerabilities or exposed sensitive data. However, explicit terms of service and direct contact information for security or business inquiries are not readily found, which could be improved to enhance trust and compliance. Overall, the site presents a professional and trustworthy platform for travel bookings.

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

3 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Invia operates in the hospitality sector as an essential e-commerce platform for travel services. It holds a strong market position as the largest online travel package seller in Slovakia, leveraging partnerships with numerous travel agencies and sister sites in neighboring countries. The business model is based on online sales and marketing of travel packages, supported by extensive use of advertising networks and tracking technologies to optimize user engagement and conversions. The company demonstrates digital maturity with integrated analytics and consent management tools. Growth potential is supported by multi-country presence and a broad service offering. Strategic partnerships with advertising and analytics providers enhance marketing effectiveness. The lack of visible direct contact details and formal security policies suggests areas for operational transparency improvement.

Security posture

The website exhibits a mature security posture with mandatory HTTPS, use of security headers, and no detected vulnerabilities in the HTML content. The cookie consent mechanism provides granular user control over data collection, supporting GDPR compliance. Use of Sentry for error monitoring indicates proactive incident detection capabilities. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms limits transparency and readiness perception. No evidence of outdated or vulnerable libraries was found. The site would benefit from publishing a security.txt file and explicit incident response procedures to improve security culture and user trust.

Recommendations

  1. Publish a clear and accessible security policy and incident response plan on the website.
  2. Implement and publish a security.txt file to facilitate vulnerability disclosure.
  3. Add explicit terms of service to clarify user agreements and legal protections.
  4. Provide clear contact information including security and abuse contacts.
  5. Enhance accessibility features to improve compliance and user experience.

Technical notes

Notes

The website uses a modern technology stack including JavaScript, CDN delivery, and third-party services for analytics, error tracking, and consent management. Performance is moderate with good mobile optimization and SEO practices. The site uses multiple external domains primarily for content delivery, analytics, and advertising. No CMS was explicitly detected, suggesting a custom or proprietary platform. The technical infrastructure supports scalability and user tracking but could improve accessibility compliance. Overall, the technical implementation supports business goals effectively with room for modernization in accessibility and transparency.
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.
