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

HEROLD Business Data GmbH operates Austria's largest online directory for local company searches and is a leading provider of online marketing services for businesses. The company offers a comprehensive suite of services including firm search, person search, online booking, website building, and domain services, targeting primarily Austrian businesses and consumers. Their market position is strong, supported by a well-designed, content-rich website that emphasizes user experience and local market relevance. Technically, the website leverages modern frameworks such as Qwik and Tailwind CSS, integrates Google Tag Manager and Ads, and employs robust email protection and marketing tools. Security-wise, the site uses valid TLS certificates with no known vulnerabilities, implements SPF and DMARC with strict policies, but lacks some advanced security headers like HSTS and DNSSEC. Overall, the company demonstrates a mature digital presence with good privacy and cookie consent mechanisms, though improvements in security configurations are recommended to enhance trust and compliance.

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 centers on providing a comprehensive online directory and marketing platform for Austrian companies, facilitating firm and person searches, and offering digital marketing solutions. Their competitive advantage lies in their extensive local market coverage and integration of online booking and marketing tools. The company targets SMEs and larger enterprises seeking enhanced online visibility and customer engagement. Partnerships with career portals and specialized search sites like arztsuche24.at expand their ecosystem. The business shows indicators of growth and digital maturity, with a focus on user-centric services and strategic marketing offerings.

Security posture

The website's security posture is solid with the use of modern TLS protocols (TLS 1.3 and 1.2) and absence of critical SSL vulnerabilities. Email security is reinforced through SPF and DMARC with a reject policy, reducing phishing risks. However, the absence of HSTS, DNSSEC, and CAA records indicates areas for improvement in DNS and transport security. No explicit security or incident response policies are publicly available, which may impact transparency and readiness. The cookie consent mechanism is comprehensive and GDPR-compliant, reflecting good data protection practices. Overall, the security maturity is moderate with room for enhancements in DNS security and incident response visibility.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to enforce HTTPS.
  2. Implement DNSSEC to protect against DNS spoofing and improve DNS integrity.
  3. Add CAA records to restrict which certificate authorities can issue certificates for the domain.
  4. Enable OCSP stapling to improve SSL certificate revocation checking performance and reliability.
  5. Publish a clear security policy and incident response plan to enhance transparency and preparedness.
Technical notes

Notes

The website is built using the Qwik framework, optimized for performance and modern web standards, with Tailwind CSS for styling. It integrates Google Tag Manager and Google Ads for analytics and marketing, and uses consentmanager.net for cookie management. Hosting is managed via Telekom Austria's DNS infrastructure. The site shows moderate load times and good mobile optimization. No standard CMS is detected, indicating a custom or proprietary solution. The technical stack is modern and well-integrated, though some security-related technical configurations could be improved to reduce risk and enhance compliance.
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.
