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

Jordi Villar's website is a personal professional blog focused on data, sports, and coding topics. The site serves as a platform for sharing technical articles, notes, and curated reads, targeting a general audience interested in data science and technology. The business model revolves around content creation and personal branding, supported by a newsletter subscription service. The domain is well-established since 2006, indicating a mature online presence. Technically, the site uses modern frameworks such as Astro and includes Tinybird's Flock.js for web vitals. Hosting appears to be managed via NameCheap with DNS servers consistent with the registrar. The website is well-optimized for performance, mobile responsiveness, and accessibility, with good SEO practices evident from meta tags and structured content. No CMS or heavy third-party analytics are detected, indicating a lightweight and privacy-conscious setup. From a security perspective, the site enforces HTTPS and has domain transfer protections in place. However, it lacks DNSSEC and security headers which could enhance its security posture. No privacy or cookie policies are published, representing compliance gaps especially under GDPR. Contact information is limited to email and social media links, with no phone or physical address provided. No vulnerability disclosure or incident response information is available. Overall, the website is trustworthy and professional with good content quality and technical implementation. The main risks relate to privacy compliance and security hardening. Strategic improvements in these areas would enhance 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 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

The website represents an individual professional's personal brand in the technology sector, specifically data science and analytics. It targets enthusiasts and professionals interested in data, machine learning, and sports analytics. The business model is content-driven, leveraging blog posts and newsletters to engage the audience. The domain's longevity and consistent content updates indicate a stable presence. The site integrates with popular social media platforms to extend reach and credibility. There is no indication of commercial transactions or partnerships, suggesting a focus on knowledge sharing and personal reputation building.

Security posture

The security maturity level is moderate. HTTPS is properly implemented, and domain registration includes clientTransferProhibited status, reducing risk of unauthorized transfers. However, the absence of DNSSEC and security headers like Content-Security-Policy or X-Frame-Options limits protection against DNS attacks and clickjacking. No exposed sensitive data or vulnerable libraries were detected. The site lacks formal security policies, incident response contacts, or vulnerability disclosure mechanisms, which are important for transparency and trust. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the site is secure for its purpose but could benefit from enhanced security controls and compliance documentation.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and cookie policy to comply with GDPR and inform users.
  3. Implement standard security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Consider adding more contact options or a dedicated security contact email to improve incident response readiness.

Technical notes

Notes

The website is built using Astro, a modern static site generator, which contributes to fast loading times and good performance. The inclusion of Tinybird's Flock.js indicates attention to web vitals and performance monitoring. The site uses minimal external dependencies, reducing attack surface and complexity. Hosting is managed through NameCheap with standard DNS servers. The HTML and CSS are valid and well-structured, supporting accessibility and SEO. There is no evidence of a traditional CMS, which reduces maintenance overhead but may limit dynamic content capabilities. Overall, the technical infrastructure is modern, efficient, and well-suited for a personal blog.
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.
