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

Herold Business Data GmbH operates Austria's largest online directory for local business searches and is a leading provider of online marketing services for companies. The website www.herold.at serves as a platform for businesses to be found locally and to access marketing solutions. The company targets Austrian businesses and local enterprises, positioning itself as a market leader in this niche. The website is professionally designed with good content relevance and clear navigation, optimized for mobile devices and SEO. Technically, the site uses modern frameworks such as Qwik, integrates Google Tag Manager and Adsense, and employs a consent management platform to comply with cookie regulations. Security-wise, HTTPS is implied, and consent mechanisms are in place, but explicit security headers and policies are not evident, indicating room for improvement. Overall, the site is trustworthy and well-established, with a consistent WHOIS registration matching the business identity. However, the absence of explicit privacy and terms of service documents and contact details slightly reduce compliance and transparency scores.

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

7 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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 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';…

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

Herold's business model revolves around providing a comprehensive online directory and marketing services tailored to Austrian businesses. Its competitive advantage lies in its market leadership and extensive local business listings. Revenue streams likely include advertising, premium listings, and marketing service fees. The target customers are local businesses seeking visibility and marketing support. The company demonstrates digital maturity with modern web technologies and consent management but could enhance compliance transparency. Partnerships with Google Adsense and Facebook indicate a robust marketing ecosystem. The business shows signs of stability and growth potential within the Austrian market.

Security posture

The website exhibits a moderate security posture with HTTPS usage and cookie consent mechanisms. However, the lack of visible security headers such as Content-Security-Policy, X-Frame-Options, and others suggests potential vulnerabilities to common web attacks. No explicit security policies or incident response contacts are published, which may hinder rapid response to security incidents. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Compliance with GDPR is partially indicated through consent management but lacks full transparency due to missing privacy policy documentation. Overall, the security maturity is adequate but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Implement and configure essential security headers to protect against common web vulnerabilities.
  3. Provide clear contact information including security incident response channels.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features to improve compliance and user experience.

Technical notes

Notes

The website is built using the Qwik framework, indicating a modern, performance-oriented architecture. Integration with Google Tag Manager and Adsense shows active marketing and analytics usage. ConsentManager scripts manage cookie consent, aligning with privacy regulations. The site uses optimized fonts and responsive design techniques, ensuring good mobile performance. However, no CMS or hosting provider details were explicitly found. Performance is moderate, with potential for improvement by optimizing resource loading and enhancing accessibility. The technical stack is solid but could be improved with better security header implementation and explicit documentation of compliance features.
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.
