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

The U.S. Department of the Interior is a key federal government agency responsible for protecting and managing the nation's natural resources, cultural heritage, and energy supplies. It serves a broad audience including the general public, tribal communities, and various government stakeholders. The website reflects the department's authoritative position with comprehensive information about its mission, bureaus, and initiatives. The presence of multiple official bureaus and partner sites underscores its extensive operational scope. Technically, the website is built on Drupal 10 and leverages the U.S. Web Design System (USWDS) to ensure accessibility and consistent branding. It integrates modern analytics tools such as Google Analytics and Siteimprove, indicating a mature digital infrastructure. The site is mobile-optimized and designed for accessibility, providing a positive user experience. From a security perspective, the site enforces HTTPS and publishes a vulnerability disclosure policy, demonstrating commitment to security best practices. However, the absence of visible security headers and a cookie consent mechanism suggests areas for improvement. The WHOIS data is not publicly available, which is typical for .gov domains, and does not detract from the site's legitimacy. Overall, the website is professional, trustworthy, and well-maintained, with minor recommendations to enhance security posture and privacy 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

3 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 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 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

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 Department of the Interior holds a dominant position in the U.S. government sector related to natural resource management and cultural heritage. Its business model is service-oriented, focusing on regulatory, conservation, and informational roles rather than commercial revenue generation. The department's extensive network of bureaus and partnerships, such as America250.org, supports its mission and outreach. The website's content and structure indicate a focus on transparency, public engagement, and compliance with government standards. Growth indicators include active news updates and engagement with social media platforms. The department's operations are critical to national interests in energy, environment, and indigenous affairs.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS and a published vulnerability disclosure policy. The use of modern CMS and analytics tools is balanced with the need for enhanced security headers and explicit privacy consent mechanisms. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of incident response contact details and security.txt file represents an opportunity to improve incident handling readiness. Overall, the security maturity is good but can be elevated by adopting additional best practices and transparency measures.

Recommendations

  1. Implement and publish security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Add a cookie consent banner or mechanism to comply fully with GDPR and other privacy regulations.
  3. Publish clear incident response contact information and consider adding a security.txt file to facilitate vulnerability reporting.
  4. Regularly audit third-party scripts and analytics tools to ensure they do not introduce vulnerabilities or privacy risks.
  5. Enhance WHOIS transparency where possible or provide official domain registration information on the website for public trust.

Technical notes

Notes

The website is built on a modern Drupal 10 CMS platform, utilizing the U.S. Web Design System for consistent and accessible UI/UX. It integrates multiple analytics and tracking services including Google Analytics, Google Tag Manager, Siteimprove Analytics, and DigitalGov Universal Federated Analytics, indicating a mature approach to performance and user behavior monitoring. The site is mobile-optimized and includes accessibility features such as font size toggles and dyslexia-friendly color schemes. Performance is moderate, likely due to the complexity and size of the site. There is no explicit hosting provider information, but the use of .gov domain and government analytics tools suggests hosting on government infrastructure.
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.
