Risk levelMedium

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

The domain holtkoetter.com is currently a parked domain with no active website content beyond a Sedo parking iframe and advertising scripts. The website lacks any business-related information, contact details, or policies, indicating it is not currently used for an operational business. The domain is registered with Network Solutions, LLC since 1998, which suggests it has been held for a long time but is not actively developed or maintained as a business site. Technically, the site uses basic HTML and JavaScript to display the parking page and ads, with no modern frameworks or CMS detected. Security posture is weak due to lack of HTTPS enforcement, absence of security headers, and no privacy or cookie policies. There are no forms or data collection mechanisms, and no analytics services are detected beyond advertising scripts. Overall, the site presents a low trust profile and minimal business credibility.

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

8 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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

No business intelligence can be derived from the website content as it is a parked domain with no company information, services, or market positioning. The domain age is significant but does not correlate with active business operations. There are no indications of partnerships, subsidiaries, or strategic business models. The presence of Sedo parking and Google ads suggests monetization attempts through domain parking rather than active commerce or service delivery.

Security posture

The security posture is minimal and insufficient for a business website. The absence of HTTPS and security headers exposes visitors to potential risks. No privacy or cookie policies are present, indicating non-compliance with GDPR and other privacy regulations. No incident response or security contact information is provided. The domain DNSSEC is not enabled, reducing DNS security. Overall, the site does not follow best practices for security or privacy.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure user connections.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and other regulations.
  3. Provide clear contact information including security incident response contacts.
  4. Enable DNSSEC to improve domain name system security.
  5. Develop active website content or redirect domain to an operational business site to improve credibility.

Technical notes

Notes

The website is a simple parked domain page served via basic HTML and JavaScript. It relies on third-party Sedo parking services and Google AdSense for monetization. No CMS or advanced frameworks are detected. The site lacks performance optimization and accessibility features. Mobile optimization is basic due to minimal content. SEO is minimal with only basic meta tags and no structured data or Open Graph tags. Hosting is provided by Network Solutions, LLC, consistent with domain registrar services. The technical setup is minimal and indicates no active website development or maintenance.
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.
