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 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';…

  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

  3. 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

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

Hindenburg Systems operates in the technology sector, focusing on audio software for spoken word production. Their business model revolves around software sales and account-based services. The company targets a diverse audience including independent professionals, businesses, and educational institutions, indicating a broad market reach within their niche. The presence of a dedicated account management domain suggests a structured customer engagement approach. The company maintains a consistent brand image and complies with European privacy regulations, enhancing its credibility. The use of multiple advertising and analytics platforms indicates active marketing efforts and data-driven decision making. The company appears stable with no signs of suspicious activity or domain registration inconsistencies.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, anonymized IP tracking in analytics, and anti-forgery tokens in forms. Cookie consent is actively managed with clear categorization of strictly necessary and targeting cookies. No exposed credentials or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy or incident response plan limits transparency. There is no vulnerability disclosure or security.txt file found, which could be improved to foster trust and facilitate responsible vulnerability reporting. Overall, the security practices align well with industry standards for a small technology company, but documentation and communication of security policies could be enhanced.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement and publish an incident response plan and contact channels for security issues.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance website accessibility to meet higher standards for users with disabilities.
  5. Create a terms of service page to clarify user rights and obligations.

Technical notes

Notes

The website uses a modern and diverse technology stack including multiple analytics and advertising platforms, a CMS (Umbraco), and hosting via Cloudflare. The site is mobile-optimized and employs smooth scrolling and lazy loading for media content. The HTML structure is valid and includes meta tags for SEO and viewport settings for responsiveness. Cookie consent is managed via CookieScript, providing detailed cookie declarations and user controls. The use of anti-forgery tokens in forms indicates secure form handling. Performance is moderate, with potential for optimization by reducing third-party script load. The technical infrastructure supports a professional and secure user experience, with opportunities to improve accessibility and reduce third-party dependencies.
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.
