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

Parsley.js is an open source JavaScript library focused on frontend form validation, providing developers with an intuitive and powerful tool to validate forms without writing JavaScript code. The project is maintained by Wisembly SAS, a French company, and has been active since 2012. The website presents clear, professional content targeting frontend developers and web designers, emphasizing ease of use, extensibility, and user experience. The business model revolves around open source software development under the MIT license, fostering community contributions and adoption. Technically, the website uses Bootstrap for styling, integrates social media widgets from Twitter, and employs Google Analytics for traffic monitoring. Hosting is provided by OVH sas, a reputable French hosting provider. The site shows moderate performance and basic mobile optimization. Accessibility and SEO optimizations are present but could be improved. The technical stack is modern but lacks advanced CMS or platform integrations. From a security perspective, the site uses HTTPS and has domain status protections to prevent unauthorized changes. However, it lacks DNSSEC, security headers, and visible privacy or cookie policies, which are important for compliance and security posture. No forms are present on the homepage, limiting exposure to input-based vulnerabilities. The absence of contact information and incident response channels reduces transparency and user trust in security matters. Overall, Parsley.js's website is trustworthy and professional but has room for improvement in privacy compliance and security best practices. Strategic enhancements in these areas would strengthen user trust and regulatory adherence.

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

9 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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"

    • 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';…

  3. 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

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

Parsley.js occupies a niche in the frontend development ecosystem as a specialized form validation library. Its competitive advantage lies in its ease of use, allowing validation rules to be written declaratively in HTML without JavaScript coding. The open source MIT license encourages widespread adoption and community contributions. Revenue streams are likely indirect, possibly through consulting or related services by Wisembly SAS. The target customers are frontend developers and web designers seeking efficient validation solutions. The project shows maturity with a decade-long presence and active maintenance. Partnerships appear limited but include social media engagement and GitHub community involvement. The business operates primarily in France with a small company size, focusing on technology innovation and developer tools.

Security posture

The security maturity of the Parsley.js website is moderate. HTTPS is enforced, and domain registration protections are in place, which are foundational security measures. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options weakens the defense-in-depth strategy. No privacy or cookie policies are published, indicating compliance gaps with GDPR and other privacy regulations. The lack of incident response contact channels and vulnerability disclosure policies reduces preparedness for security incidents. No forms on the homepage reduce attack surface but also limit user engagement options. Overall, the site demonstrates basic security hygiene but requires enhancements to meet modern security and privacy standards.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies to enhance GDPR compliance and user trust.
  3. Implement security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web vulnerabilities.
  4. Provide clear contact information and dedicated security incident response channels (e.g., security@ or abuse@ emails).
  5. Improve mobile optimization and accessibility to broaden user reach and comply with accessibility standards.

Technical notes

Notes

The website is built using Bootstrap CSS framework and JavaScript, with external integrations including Twitter widgets and Google Analytics. Hosting is provided by OVH sas, a reputable French provider. The site loads external CSS and JS resources from trusted CDNs. Performance is moderate with no evident broken elements. The HTML is valid and includes meta tags for description and viewport settings, supporting basic SEO. Accessibility features are minimal but present. The site lacks a CMS and appears to be a static or lightly dynamic site focused on documentation and downloads. Technical debt is low, but modernization opportunities include enhanced SEO, accessibility, and security header implementation.
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.
