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

Zeppelin is a specialized technology company offering an intelligent Hotel Marketing Platform designed to enhance hotel websites, online marketing, content creation, and sales optimization. The company targets the hospitality industry with a B2B SaaS business model, positioning itself as a niche provider in hotel marketing technology. The website is built on TYPO3 CMS and integrates modern marketing and analytics tools such as Google Tag Manager, HubSpot, Hotjar, and Usercentrics for consent management. The technical infrastructure reflects a moderate level of digital maturity with good mobile optimization and SEO practices. Security posture is strong with HTTPS enforcement and appropriate security headers, although explicit security policies and incident response information are not publicly available. Privacy compliance is basic, with a cookie consent mechanism present but lacking a visible privacy policy or terms of service. Overall, Zeppelin's website is professional and trustworthy but would benefit from enhanced transparency in privacy and contact information.

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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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

Zeppelin operates in the technology and hospitality sectors, providing hotel marketing solutions that include website development, online marketing, and content creation services. The company appears to focus on small to medium-sized hotel businesses seeking to improve direct sales and marketing effectiveness. The business model is subscription-based SaaS, leveraging digital marketing tools to deliver value. The website's integration with HubSpot and Facebook Ads indicates active marketing and retargeting strategies. While no parent or subsidiary companies are identified, Zeppelin maintains a consistent brand presence and uses professional fonts and verified Google site ownership. The absence of detailed company contact information and legal disclosures suggests room for improvement in business transparency and customer trust.

Security posture

The website demonstrates a good security posture with HTTPS enabled and multiple security headers such as Strict-Transport-Security, Content-Security-Policy, and X-Frame-Options. The use of a consent management platform (Usercentrics) aligns with GDPR requirements for cookie consent. No exposed sensitive data or vulnerable libraries were detected in the provided content. However, the lack of published security policies, incident response plans, or vulnerability disclosure mechanisms limits the overall security maturity. The site does not appear to be behind a WAF or present any blocking challenges, indicating stable accessibility. Recommendations include publishing explicit security and incident response policies and implementing a security.txt file to improve transparency and readiness.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve legal compliance and user trust.
  2. Provide clear company contact information including official emails and phone numbers for support and sales.
  3. Implement and publicize an incident response policy and vulnerability disclosure program.
  4. Enhance accessibility features to meet compliance standards and improve user experience.
  5. Maintain and regularly update security headers and monitor third-party scripts for vulnerabilities.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust open-source content management system, and uses a modern tech stack including JavaScript libraries for analytics and marketing integrations. Google Tag Manager is used for managing tracking scripts, alongside HubSpot for marketing automation and Hotjar for user behavior analytics. The site loads CSS and JS assets in compressed form, indicating performance optimization efforts. Mobile optimization is good, and SEO meta tags including Open Graph and Twitter cards are properly configured. Hosting provider details are not explicitly available. The site shows moderate performance with room for improvement in accessibility compliance. Technical risks are minimal but depend on third-party script security and privacy compliance 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.
