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

    • 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

  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 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

heroal holds a strong market position as a technological leader in aluminum processing for building systems in Germany. Their competitive advantages include a long company history dating back to 1874, premium German manufacturing, and a broad product portfolio covering windows, doors, roller shutters, sun protection, and more. Revenue streams likely derive from product sales through a partner network and value-added services such as configurators and energy consulting partnerships. The target customer segments include private homeowners, architects, and processors. Growth indicators include digital configurators, energy consulting partnerships, and active social media engagement. The partnership with Fuchs & Eule for energy consulting and funding support expands their service ecosystem. Strategic observations suggest a focus on sustainability, quality certifications, and customer-centric digital tools to maintain market leadership.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and integration of consent management and reCAPTCHA for form protection. The absence of explicit security headers like CSP, HSTS, and X-Frame-Options is a minor gap. No exposed sensitive data or vulnerable libraries were detected. The lack of a published security policy or incident response contact limits transparency and readiness communication. No vulnerability disclosure policy or security.txt file was found, which is recommended for responsible disclosure. Overall, the site is secure for users but could improve by publishing security policies and adding security headers to harden defenses.

Recommendations

  1. Implement and publish explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance protection against common web attacks.
  2. Create and publish a security policy page including incident response contacts (e.g., security@heroal.de or abuse@heroal.de) to improve transparency and readiness.
  3. Develop and host a vulnerability disclosure policy and security.txt file to encourage responsible reporting of security issues.
  4. Provide contact information for a Data Protection Officer (DPO) to strengthen GDPR compliance and user trust.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance with evolving data protection regulations.

Technical notes

Notes

The website uses a modern technology stack including JavaScript libraries, Google Tag Manager for analytics, Usercentrics for consent management, and AddSearch for site search functionality. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate with preloading of fonts and asynchronous loading of scripts. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The site integrates embedded Vimeo videos and external partner links. Technical risks are low but could be further mitigated by adding security headers and improving incident response transparency.
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.
