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

JSPM.IO is a specialized CDN package provider supporting the JSPM project, a JavaScript package manager ecosystem. The website presents a focused business model delivering CDN services to developers and technology users. The domain is mature, registered since 2013, and hosted on reliable infrastructure with Cloudflare DNS and CacheFly sponsorship. The website content is minimal but professional, emphasizing the core service without extraneous information or marketing. Technically, the site uses modern web technologies such as import maps and ES modules, with good mobile optimization and basic accessibility. Security posture is solid with HTTPS enforced and domain status protections, though DNSSEC is not enabled and no security headers are explicitly detected. Privacy and compliance documentation such as privacy policy, cookie policy, and terms of service are absent, which reduces compliance confidence. No contact information or incident response details are provided, limiting transparency. Overall, the site is trustworthy and functional for its niche audience but could improve in compliance and security communication.

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

8 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

JSPM.IO operates in the technology sector, targeting developers needing CDN package delivery for JavaScript projects. The business model is service-oriented, focusing on infrastructure support for the JSPM ecosystem. The domain's long registration age and use of privacy proxy are consistent with a mature technology project. Partnerships include CacheFly as infrastructure sponsor and references to jspm.org and framer.com domains. The company appears small but stable, with no public subsidiaries or parent company indicated. The website branding is consistent and professional, though content is sparse. No direct revenue streams or monetization details are visible. The lack of contact or compliance information suggests a lean operation focused on technical service delivery rather than broad commercial engagement.

Security posture

The website enforces HTTPS and uses domain status flags to prevent unauthorized domain changes, indicating good baseline security. However, DNSSEC is not enabled, which is a missed opportunity to enhance DNS security. No security headers such as Content-Security-Policy or X-Frame-Options are detected, which could improve protection against common web attacks. The absence of privacy, cookie, or incident response policies reduces transparency and compliance posture. No forms or user input fields are present, minimizing attack surface. No analytics or tracking scripts are detected, reducing privacy risks. Overall, the security posture is moderate with room for improvement in DNS security and policy publication.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and security.
  2. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear contact information and incident response channels for security reporting.
  5. Implement a vulnerability disclosure policy or security.txt file to enhance transparency and trust.

Technical notes

Notes

The website uses modern web standards including import maps and ES modules, indicating up-to-date technical implementation. Hosting is supported by CacheFly infrastructure and Cloudflare DNS, providing reliable performance and security. The site is mobile optimized with responsive design and basic accessibility features. SEO optimization is basic with meta tags and Open Graph data present but no advanced structured data or analytics detected. No CMS or frameworks are explicitly identified, suggesting a custom or lightweight static site. Performance is moderate given the minimal content and external resource usage. Technical debt appears low but opportunities exist to enhance security headers and compliance documentation.
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.
