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

5 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

The company operates a B2B business model focusing on technology and content aggregation for the travel sector. Their competitive advantage lies in their hybrid offering of both travel IT solutions and payment services, enabling them to provide fully aggregated solutions. The presence of multiple subsidiaries and partner companies enhances their service ecosystem. Their target customers include airlines, consolidators, OTAs, and travel portals. The company demonstrates growth potential through its scalable infrastructure and global content reach. Strategic partnerships and certifications further solidify their market credibility.

Security posture

Ypsilon.Net AG exhibits a mature security posture with adherence to industry-leading standards such as PCI DSS Level 1 and ISO 27001. The website and company documentation emphasize strong customer authentication (PSD2 / SCA) and secure payment processing. No critical vulnerabilities or exposed sensitive data were detected in the website content. However, the absence of explicit security headers and incident response contact information suggests areas for improvement. The company should consider publishing a vulnerability disclosure policy and enhancing cookie consent mechanisms to strengthen compliance and transparency.

Recommendations

  1. Implement and enforce security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options to improve web security.
  2. Publish clear incident response and vulnerability disclosure information, including a security.txt file or dedicated security contact email.
  3. Add a visible cookie consent mechanism to comply fully with GDPR and enhance user privacy transparency.
  4. Enhance website accessibility features to meet recognized standards and improve user experience for all visitors.
  5. Regularly review and update technical infrastructure and security certifications to maintain trust and compliance.

Technical notes

Notes

The website is built on a modern Nuxt.js and Vue.js framework with usage of Swiper.js for interactive elements and PDFMake for document generation. The tech stack is contemporary and supports responsive design, providing a good user experience across devices. Performance is moderate with room for optimization. The hosting provider is not explicitly identified, but the domain is stable and well-maintained. The website lacks some advanced SEO and accessibility features but maintains good content structure and navigation clarity. Technical debt appears low, with opportunities to enhance security headers and privacy compliance mechanisms.
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.
