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

CdnFlex is a newly established free and open-source content delivery network service focused on delivering popular JavaScript libraries, CSS frameworks, and static assets efficiently. It leverages Cloudflare's infrastructure to provide fast and reliable content delivery, serving a significant portion of websites globally. The website presents a clean and professional landing page with clear messaging about its services and target audience of developers and website owners. However, it lacks critical compliance and contact information such as privacy policies, cookie consent mechanisms, and terms of service, which are important for trust and regulatory adherence. Technically, the site is simple but well-structured, with good performance and mobile optimization, though it does not implement advanced SEO or accessibility features. Security posture is moderate with domain transfer protection and Cloudflare hosting but lacks DNSSEC and security headers. Overall, the site is legitimate but would benefit from enhanced compliance and security transparency.

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. 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 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

    • 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

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

CdnFlex operates in the technology sector as a small-scale, community-driven CDN provider. Its business model is based on offering free access to popular web libraries, positioning itself as a reliable alternative to commercial CDNs. The service targets developers and website owners who require fast, easy integration of libraries without hosting overhead. Powered by Cloudflare, it benefits from robust infrastructure and global reach. The lack of published business contact details and compliance documentation suggests a lean operation focused on technical delivery rather than commercial engagement. Growth potential exists given the large market for CDN services, but establishing formal policies and contact channels would improve credibility and partnership opportunities.

Security posture

The security maturity of the website is moderate. The domain is protected against unauthorized transfers and uses Cloudflare DNS, which provides resilience and performance benefits. However, the absence of DNSSEC and security headers reduces protection against DNS spoofing and common web attacks. No privacy or security policies are published, and no incident response contacts are provided, which limits transparency and preparedness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site does not collect user data or have forms, reducing attack surface. To improve security posture, the site should implement DNSSEC, add security headers, publish privacy and security policies, and provide incident response contacts.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  3. Add standard security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  4. Provide clear contact information including security incident response and data protection officer contacts.
  5. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website is built with clean, valid HTML and CSS, featuring an embedded SVG logo for branding. It is hosted on Cloudflare, ensuring fast content delivery and global availability. The site is mobile optimized with responsive design and uses modern font stacks for good typography. No CMS or JavaScript frameworks are detected, indicating a static site approach which reduces complexity and attack surface. SEO optimization is basic with minimal meta tags and no structured data or Open Graph tags. Accessibility features are minimal but text contrast and font sizes are adequate. The site does not use analytics or tracking scripts, enhancing privacy but limiting marketing insights. Overall, the technical implementation is solid for a simple informational site but could be enhanced with SEO and accessibility improvements.
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.
