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

jQuery.com represents the official website for the jQuery JavaScript library, a widely adopted open-source project supported by the OpenJS Foundation. The site provides comprehensive resources including downloads, documentation, community support, and related projects. The business model centers on open-source software development with community contributions and foundation backing, positioning jQuery as a key player in web development technology. The website is professionally designed, well-structured, and targets developers and web professionals globally. Technically, the site leverages WordPress CMS, integrates modern JavaScript libraries including jQuery itself, and uses Typesense for search functionality. Hosting is provided by Digital Ocean with DNS managed via Cloudflare, ensuring good performance and availability. The site is mobile optimized and SEO friendly, with clear navigation and rich content. From a security perspective, the site enforces HTTPS and employs domain transfer protections. However, DNSSEC is not enabled and security headers are not visibly configured, representing areas for improvement. No direct incident response or vulnerability disclosure mechanisms are published, which could enhance security posture. Privacy compliance is strong with clear policies, though no explicit cookie consent mechanism is present. Overall, jQuery.com is a high-quality, trustworthy website with strong business credibility and technical maturity. Strategic recommendations include enabling DNSSEC, adding security headers, publishing vulnerability disclosure information, and implementing cookie consent to further enhance security and 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

4 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

jQuery is a mature and influential open-source JavaScript library project with a strong community and foundation support via the OpenJS Foundation. Its market position is solid as a foundational technology in web development. The business model is non-commercial but sustained through foundation sponsorship and community contributions. The target audience includes web developers and software engineers seeking efficient client-side scripting tools. The project ecosystem includes related projects like jQuery UI and jQuery Mobile, though some are deprecated or in maintenance mode. Partnerships with the OpenJS Foundation and hosting providers like Digital Ocean support operational stability. The website content and resources reflect a professional and well-maintained project with ongoing modernization efforts.

Security posture

The website demonstrates a good security posture with mandatory HTTPS, domain transfer lock status, and use of reputable DNS providers. However, the absence of DNSSEC and missing security headers such as Content-Security-Policy and Strict-Transport-Security are notable gaps. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The lack of published incident response contacts or security.txt file limits transparency for vulnerability reporting. Privacy policies are comprehensive and GDPR compliant, but cookie consent mechanisms are absent. Overall, the security maturity is good but could be improved with additional controls and transparency.

Recommendations

  1. Enable DNSSEC to protect against DNS spoofing and enhance domain security.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a security.txt file and provide clear incident response contact information to facilitate vulnerability reporting.
  4. Add a cookie consent mechanism to comply fully with GDPR and enhance user privacy transparency.
  5. Regularly review and update third-party dependencies and monitor for vulnerabilities.

Notes

The website is built on WordPress 6.8.2 CMS, utilizing jQuery 3.7.1 and Typesense for search functionality. Hosting is provided by Digital Ocean with CDN services from Fastly, contributing to fast load times and good performance. The site is mobile optimized and accessible with semantic HTML and ARIA roles. SEO is well addressed with meta tags, canonical links, and structured navigation.

Overall, the technical infrastructure supports a reliable and performant user experience.
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.
