The infrastructure described includes a scalable server environment capable of handling high query volumes, reflecting a mature digital presence. Security certifications including PCI DSS Level 1, ISO 27001, and PSD2 compliance underscore a robust security posture. The website employs HTTPS and demonstrates best practices in data protection, although some improvements in security headers and incident response transparency are recommended. Overall, the security posture is strong with no visible vulnerabilities or exposed sensitive data. Privacy compliance is well addressed with clear privacy and cookie policies, though a consent mechanism could be enhanced. The business credibility is high, supported by consistent branding, comprehensive contact information, and trust indicators such as certifications and CEO statements.

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.

Business context

Business profile

Ypsilon.Net AG operates as a hybrid technology and payment service provider in the travel industry, uniquely combining travel IT solutions with payment and fraud prevention services. Their competitive advantage lies in their comprehensive content aggregation from multiple sources and their PCI DSS Level 1 and ISO 27001 certifications, which are critical for trust in payment processing. The company targets airlines, travel agencies, OTAs, and consolidators, offering scalable and secure solutions that support global distribution and booking. The presence of multiple subsidiaries and related companies indicates a diversified business ecosystem. Growth indicators include a long operational history, extensive client base, and partnerships with major industry players. The company’s business model focuses on B2B SaaS and payment processing, generating revenue through licensing, transaction fees, and service contracts.

Security posture

Ypsilon.Net AG demonstrates a mature security posture with adherence to industry-leading standards such as PCI DSS Level 1, ISO 27001, and PSD2 compliance. The website and business infrastructure emphasize secure payment processing, strong customer authentication, and fraud prevention tailored to the travel industry. No critical vulnerabilities or exposed sensitive data were detected in the website content. However, the absence of a published security.txt and explicit incident response contacts suggests room for improvement in vulnerability disclosure and incident management transparency. The use of HTTPS and secure coding practices is evident, but additional security headers could enhance protection against common web threats. Overall, the company shows a strong commitment to security, aligning with the sensitive nature of payment and personal data handled.

Recommendations

  1. Publish a security.txt file to facilitate responsible vulnerability disclosure.
  2. Add explicit incident response contact information on the website.
  3. Implement a cookie consent mechanism to comply fully with privacy regulations.
  4. Enhance website security headers such as Content-Security-Policy and X-Content-Type-Options.
  5. Improve accessibility features to meet higher compliance standards and broaden user inclusivity.

Technical notes

Notes

The website is built using modern JavaScript frameworks including Vue.js and Nuxt.js, indicating a contemporary and maintainable tech stack. The use of Swiper.js for interactive elements and PDFMake for document generation shows thoughtful integration of specialized libraries. The site is mobile optimized with responsive design and good navigation clarity. Performance is moderate, with potential for improvement through optimization of assets and caching strategies. Hosting details are not explicitly disclosed, but the infrastructure described in content suggests a robust multi-center server environment. Technical risks are minimal, though the lack of DNSSEC and some security headers could be addressed to enhance DNS and web security. Overall, the technical implementation supports the business needs effectively with opportunities for incremental 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.
