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

The National League of Cities (NLC) is a well-established non-profit organization dedicated to strengthening cities across the United States through advocacy, resources, training, and events. The website reflects a mature digital presence with comprehensive content targeting city leaders and municipal officials. It offers membership services, advocacy centers, resource libraries, and organizes conferences such as the City Summit and Congressional City Conference. The organization maintains a strong market position as a leading voice for local governments. Technically, the website is built on WordPress with modern technologies including jQuery, Google Tag Manager, Google Analytics, and New Relic for performance monitoring. The site is mobile-optimized, accessible, and SEO-friendly, providing a good user experience. The presence of privacy and cookie policies with consent mechanisms indicates attention to privacy compliance. From a security perspective, the site uses HTTPS with a good SSL configuration but lacks explicit security headers in the provided data. No vulnerabilities or sensitive data exposures were detected. The WHOIS data is unavailable due to a malformed response, but the website's professionalism and consistency suggest legitimacy. The organization uses multiple social media channels and partners with related domains for insurance, events, and community engagement. Overall, the site demonstrates a strong security posture, good privacy compliance, and high business credibility. Recommendations include implementing security headers, publishing a vulnerability disclosure policy, and enhancing incident response visibility to further strengthen trust and security.

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 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 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

NLC operates as a membership-based non-profit serving local governments and city officials. Its competitive advantage lies in its comprehensive advocacy efforts, extensive resource offerings, and well-established events that engage municipal leaders nationwide. Revenue streams likely include membership dues, event fees, and partnerships. The target customer segment is municipal officials and city leaders seeking support and advocacy. Growth indicators include active event promotion and digital engagement. The partnership ecosystem includes insurance services and specialized programs like RISC. Strategic observations highlight a focus on digital modernization and community building through online discussion groups and resource libraries.

Security posture

The website exhibits a mature security posture with HTTPS enforced and privacy policies in place. However, the absence of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for improvement. No exposed credentials or vulnerabilities were found in the HTML content. The site uses third-party analytics and monitoring tools responsibly, with cookie consent mechanisms supporting GDPR compliance. Incident response and vulnerability disclosure information are not publicly available, which could be enhanced to improve transparency and readiness. Overall, the security culture appears proactive but could benefit from formalized policies and headers.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a publicly accessible vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Enhance incident response visibility by providing dedicated security contact channels such as security@ or abuse@ emails.
  4. Regularly audit and update third-party scripts and libraries to minimize risk from vulnerabilities.
  5. Continue to maintain and improve privacy compliance mechanisms, including clear data retention policies and user rights disclosures.

Technical notes

Notes

The website is powered by WordPress CMS with a custom theme and uses modern JavaScript libraries such as jQuery. It integrates Google Tag Manager and Google Analytics for marketing and performance tracking, alongside New Relic for real-time monitoring. The site loads asynchronously and defers non-critical scripts to optimize performance. Mobile responsiveness and accessibility features are well implemented. The site architecture supports clear navigation and SEO best practices. Technical risks are minimal but include the need for enhanced security headers and formal vulnerability disclosure mechanisms. Hosting provider details are not explicitly identified from the content.
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.
