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

The website us-cert.gov is a U.S. government domain associated with the United States Computer Emergency Readiness Team under the Department of Homeland Security. It serves as a critical national cybersecurity resource. However, the website content is currently inaccessible due to a Web Application Firewall or security mechanism blocking access, as evidenced by the 'Access Denied' page and reference to errors.edgesuite.net. This prevents direct analysis of the site's content, metadata, or technical infrastructure. The domain registration data confirms the legitimacy and government affiliation of the site, consistent with its mission. Due to the blocked content, no detailed technical infrastructure or digital maturity assessment can be performed. No metadata, scripts, or forms are accessible to evaluate. Security posture cannot be fully assessed beyond the indication that a WAF is in place, which is a positive security control. No privacy or cookie policies are detectable, nor are contact or incident response details visible. Overall, the site appears to be a legitimate government cybersecurity resource with strong domain registration trustworthiness. The blocking mechanism suggests a high-security posture to protect the site from unauthorized access or attacks. However, this also limits external analysis and transparency. Strategic recommendations include ensuring public-facing content is accessible to authorized users and providing clear contact and policy information to enhance trust and compliance visibility.

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

6 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 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

    • 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

US-CERT operates as a critical government cybersecurity entity providing incident response and threat intelligence services to U.S. federal agencies and the public. Its market position is authoritative within the government sector, focusing on national cybersecurity defense. The business model is non-commercial, funded by government budgets, targeting government agencies, critical infrastructure operators, and cybersecurity professionals. The domain and entity are consistent with a large enterprise government organization. No commercial partnerships or subsidiaries are evident from the data. The site likely serves as an information dissemination and incident coordination platform.

Security posture

The presence of a WAF or security blocking mechanism indicates a mature security posture aimed at protecting the site from unauthorized access and attacks. However, the lack of accessible content prevents evaluation of security headers, SSL configuration, or vulnerability disclosures. No incident response contact information or security policies are publicly visible, which may limit external reporting and transparency. The domain registration is consistent and trustworthy, reducing risk of impersonation. Overall, the security posture appears strong but opaque due to access restrictions.

Recommendations

  1. Ensure that public-facing content is accessible to legitimate users without triggering WAF blocks to improve transparency and usability.
  2. Publish clear privacy, cookie, and terms of service policies to enhance compliance and user trust.
  3. Provide accessible incident response and vulnerability disclosure contact information to facilitate security communication.
  4. Implement and publicly document security headers and SSL configurations to demonstrate best practices.
  5. Consider providing a security.txt file or similar mechanism to improve vulnerability reporting and security culture.

Key observations

  1. Website content is inaccessible due to a WAF or security block.
  2. No metadata, forms, scripts, or contact information available in the HTML.
  3. No privacy, cookie, or terms of service policies detected.
  4. No visible security headers or SSL configuration details available.
  5. Domain WHOIS data indicates a legitimate U.S. government registration.
  6. External domain linked is errors.edgesuite.net, likely related to CDN or WAF error handling.
  7. No advertising, analytics, or tracking technologies detected due to blocked content.
Technical notes

Notes

Due to the access denial and minimal HTML content, no technical stack, CMS, or hosting provider information could be extracted. The site is protected by a WAF, likely provided by a CDN or security service referencing edgesuite.net. No scripts, analytics, or tracking technologies are detectable. Performance, mobile optimization, and SEO cannot be assessed. The domain is government-owned and likely hosted on secure government infrastructure. Technical modernization opportunities cannot be identified without further access.
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.
