American Civil Liberties Union · Non-profit · United States
Medium risk. 4 critical or high findings in SSL/TLS, GDPR outside view and 1 other check.
The American Civil Liberties Union (ACLU) is a well-established non-profit organization dedicated to defending and expanding civil liberties and constitutional rights across the United States. The website serves as a comprehensive platform for advocacy, education, and fundraising, targeting a broad audience including activists, donors, and the general public. It offers detailed information on key civil rights issues, campaigns, legal battles, and resources such as 'Know Your Rights' materials. The ACLU maintains a strong market position as a leading civil liberties organization with a large national presence. Technically, the website is built on WordPress with modern enhancements including Vue.js components, Yoast SEO for optimization, and integrations with analytics and marketing tools like Heap and Optimizely. The site demonstrates good mobile responsiveness, accessibility, and SEO practices, contributing to a positive user experience. Performance is moderate, with room for optimization in hosting and resource delivery. From a security perspective, the site enforces HTTPS and uses secure forms for data collection. However, explicit security headers are not detected in the provided data, and no public security or incident response policies are found. The absence of a vulnerability disclosure or security.txt file suggests an opportunity for improvement in transparency and security maturity. No vulnerabilities or suspicious elements are evident in the content or scripts. Overall, the ACLU website is a trustworthy, professional, and content-rich platform that effectively supports the organization's mission. The domain registration data is privacy-protected but consistent with the organization's long-standing history. Strategic recommendations include enhancing security header implementation, publishing security policies, and adding vulnerability disclosure mechanisms to further strengthen trust and security posture.
Scanned
NIS2 Art. 21(2)
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.
4 findings rated critical or high. Fix these first.
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
Server supports weak protocols: TLSv1.1
What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions
These are the privacy signals visitors and data protection authorities look for under GDPR.
GDPR requires clear information about cookie usage
What to do: Add a dedicated cookie policy explaining cookie usage and purposes
GDPR requires explicit consent for non-essential cookies
What to do: Implement a cookie consent banner that appears on first visit
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.

Each check with its score, findings and the evidence it collected.
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.

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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
