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

The Harry S. Truman Library and Museum website represents a government/non-profit institution dedicated to preserving the legacy of President Harry S. Truman. The domain is long-established, dating back to 1998, consistent with the institution's history. However, the website content is minimal and primarily consists of an embedded iframe from an external source, with no visible privacy, cookie, or terms of service policies. Contact information and social media links are absent, limiting user engagement and trust signals. Technically, the site uses basic HTML and JavaScript without modern frameworks or CMS detection. The domain's DNS configuration raises concerns due to the use of 'pendingrenewaldeletion.com' name servers, suggesting potential domain management issues. Security headers and DNSSEC are not implemented, and the SSL configuration is basic, indicating room for improvement in security posture. From a security perspective, the site lacks standard best practices such as security headers and DNSSEC, and no incident response or vulnerability disclosure information is present. The presence of third-party ads and tracking pixels without clear privacy policies further reduces privacy compliance. Overall, the site scores low on content quality, technical implementation, security, and privacy compliance, resulting in a moderate risk profile. Strategic recommendations include updating domain name servers, enabling DNSSEC, implementing comprehensive privacy and cookie policies, adding contact information, and enhancing security headers and SSL configurations to improve 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

10 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

The Harry S. Truman Library and Museum operates as a specialized government/non-profit entity focused on historical preservation and education. Its market position is niche, serving researchers, historians, and the general public interested in presidential history. The business model is non-commercial, relying on public funding and institutional support. The lack of visible partnerships or subsidiaries suggests a standalone operation. The website's minimal content and lack of engagement features may limit outreach and growth potential. There is no evidence of revenue streams or commercial activities. The institution's long history and domain age support its credibility, but domain management issues could impact reputation.

Security posture

The current security posture is weak. The absence of DNSSEC, security headers, and advanced SSL configurations exposes the site to potential DNS spoofing and man-in-the-middle attacks. The domain's name servers pointing to 'pendingrenewaldeletion.com' is a significant red flag indicating possible domain expiration or mismanagement. No incident response or vulnerability disclosure mechanisms are evident, and no security contact channels are provided. The presence of third-party ads and tracking pixels without privacy disclosures further complicates compliance with GDPR and other privacy regulations. Overall, the site requires urgent security improvements to protect its users and maintain institutional trust.

Recommendations

  1. Update domain name servers to valid authoritative servers and enable DNSSEC to secure DNS resolution.
  2. Develop and publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  3. Add clear contact information including emails and phone numbers for general and security-related inquiries.
  4. Implement standard security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  5. Conduct a security audit to identify and remediate vulnerabilities and establish an incident response plan.

Technical notes

Notes

The website uses basic HTML and JavaScript without detectable modern frameworks or CMS platforms. The content is minimal and primarily loaded via an iframe from an external domain, which may impact performance and user experience. Mobile optimization is basic, and SEO elements such as meta tags and structured data are absent. Hosting provider details are not discernible from the content. The domain's DNS configuration is problematic due to name servers indicating pending renewal or deletion status. Performance is moderate but could be improved with better infrastructure and content delivery strategies.
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.
