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

Monteurzimmer.at is a well-established online platform specializing in affordable accommodation listings for workers and travelers in Austria. The website offers over 1,000 budget-friendly lodging options with direct contact to landlords and free mediation services, positioning itself as a key player in the hospitality sector targeting a niche audience of monteurs and budget travelers. The platform supports multiple languages, enhancing accessibility for diverse users. Technically, the site employs modern web technologies including Google Maps API and Google Tag Manager, ensuring functional and analytical capabilities. Security measures such as HTTPS and multiple security headers are implemented, reflecting a good security posture. Privacy and cookie policies are comprehensive and GDPR compliant, indicating strong privacy awareness.

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 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 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

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 platform operates in the hospitality and real estate sectors, focusing on budget accommodation for workers and travelers in Austria. Its business model revolves around listing properties and facilitating direct landlord-tenant communication without charging mediation fees. The multilingual approach and partnerships with sister sites in Germany and other regions expand its market reach. The company maintains a medium-sized operation with consistent branding and good content quality. Trust signals include SSL encryption, clear contact details, and privacy compliance. The absence of detailed WHOIS data suggests privacy protection, which is justified given the nature of the business. The platform leverages Google services for analytics and mapping, supporting data-driven decision-making and enhanced user experience.

Security posture

Monteurzimmer.at exhibits a solid security posture with enforced HTTPS, presence of key security headers such as HSTS, X-Frame-Options, and Content-Security-Policy. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The use of Google Tag Manager is properly implemented, and forms appear secure with no visible injection vulnerabilities. Privacy policies and cookie consent mechanisms are in place, supporting GDPR compliance. The main security recommendation is to enhance CSP implementation with nonces or hashes and to apply Subresource Integrity for external scripts to further mitigate risks. Incident response and vulnerability disclosure information are not publicly available, which could be improved to enhance transparency and trust.

Recommendations

  1. Implement CSP with nonce or hash-based whitelisting for inline scripts to strengthen content security.
  2. Add Subresource Integrity (SRI) attributes to all external scripts and stylesheets to prevent tampering.
  3. Publish a clear vulnerability disclosure policy and incident response contact to improve security transparency.
  4. Regularly audit third-party libraries and dependencies for vulnerabilities and update accordingly.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website uses a modern tech stack with HTML5, CSS, JavaScript, and integrates Google Maps and Google Tag Manager for enhanced functionality and analytics. The site is mobile-optimized with responsive design and good SEO practices including meta tags and multilingual support. Performance is moderate, with CDN usage for static assets improving load times. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The site shows good technical implementation but could benefit from improved accessibility and advanced security headers configuration.
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.
