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

Tailwind CSS is a widely recognized utility-first CSS framework designed to enable rapid development of modern websites directly within HTML markup. The website serves as the primary resource for developers and designers, offering comprehensive documentation, examples, and sponsorship opportunities. Tailwind Labs, the entity behind the framework, has established a strong market position with a medium-sized team and a focus on modern web technologies. The technical infrastructure leverages Next.js and React, hosted with Cloudflare DNS, ensuring fast performance and excellent mobile optimization. Security posture is solid with HTTPS enforced and domain transfer protections, though there is room for improvement in publishing explicit security policies and enabling DNSSEC. Privacy compliance is limited due to the absence of visible privacy and cookie policies. Overall, the website is professional, trustworthy, and technically mature, catering effectively to its target audience of web developers.

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

7 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

Tailwind CSS operates in the technology sector, specifically targeting frontend web development. Its business model revolves around open-source software with additional paid offerings and sponsorship programs, fostering a community-driven ecosystem. The company maintains partnerships with several technology service providers, enhancing its product and reach. The website's content quality and branding consistency reflect a mature and professional organization. While direct contact information is not prominently displayed, the presence of a GitHub repository and sponsorship links indicate active community engagement and transparency. The domain's registration details align well with the company's history, supporting legitimacy and trustworthiness.

Security posture

The website demonstrates a good security baseline with HTTPS enabled and domain status flags that prevent unauthorized transfers or updates. However, the lack of DNSSEC implementation and absence of explicit security policies or incident response contacts represent areas for enhancement. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The use of modern frameworks and hosting providers contributes positively to the security posture. Privacy compliance is minimal, with no visible privacy or cookie policies, which could pose compliance risks under regulations like GDPR. Overall, the security maturity is moderate, with recommendations to formalize security documentation and improve DNS security.

Recommendations

  1. Enable DNSSEC to enhance domain name system security and prevent DNS spoofing.
  2. Publish comprehensive privacy and cookie policies with clear consent mechanisms to improve GDPR compliance.
  3. Develop and display a formal security policy and incident response contact information to build trust and readiness.
  4. Implement security headers such as Content-Security-Policy and X-Frame-Options to mitigate common web vulnerabilities.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Opportunities exist to enhance security configurations and formalize privacy compliance mechanisms.
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.
