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

Brian Kardell's website serves as a personal professional platform highlighting his role as a Developer Advocate at Igalia and his contributions to web standards and extensibility. The site features his writings, talks, and art, targeting web developers and technology enthusiasts interested in web standards and innovation. The business model is centered on personal branding, thought leadership, and community engagement rather than commercial transactions. Technically, the website employs modern web technologies including custom web components and CSS, hosted with DNS services via Cloudflare and domain registration through Squarespace. The site is moderately performant, mobile-optimized, and accessible, though it lacks some advanced SEO and security headers. There are no forms or data collection mechanisms, minimizing privacy risks. From a security perspective, the site uses HTTPS (implied by Cloudflare usage), but lacks DNSSEC and security headers, which are recommended for enhanced protection. No privacy or cookie policies are present, which limits GDPR compliance. No contact information or incident response channels are provided, which could hinder security communication. The domain registration is consistent and stable, supporting the site's legitimacy. Overall, the website is a well-maintained personal professional site with good content quality and business credibility but has room for improvement in privacy compliance and security hardening. Strategic recommendations include adding privacy and cookie policies, enabling DNSSEC, implementing security headers, and providing contact information for security incidents.

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

10 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

Brian Kardell positions himself as a niche thought leader and advocate in the web standards and extensibility space. His affiliations with Igalia and W3C, along with his co-authorship of The Extensible Web Manifesto, establish credibility and influence. The website supports his personal brand by showcasing writings, talks, and art, appealing to a specialized audience of developers and standards enthusiasts. The business model is non-commercial, focusing on professional reputation and community contribution. The external links to social media and professional platforms reinforce his network and outreach. There is no indication of revenue streams or partnerships beyond personal affiliations.

Security posture

The website demonstrates a basic security posture with HTTPS enabled (inferred), but lacks DNSSEC and common security headers such as Content-Security-Policy and Strict-Transport-Security. No forms or user input fields reduce attack surface. Absence of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. No incident response or security contact information is provided, limiting readiness for security events. The domain registration status with clientDeleteProhibited and clientTransferProhibited flags is a positive control against unauthorized domain changes. Overall, security maturity is moderate but could be improved with standard best practices and compliance documentation.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a comprehensive privacy policy and cookie policy to improve GDPR and privacy compliance.
  4. Add clear contact information for security incident reporting and general inquiries.
  5. Regularly audit and update all scripts and dependencies to mitigate vulnerabilities.

Technical notes

Notes

The website uses a custom-built frontend leveraging modern web standards such as custom elements and CSS grid layouts. It is hosted with DNS managed by Cloudflare and domain registered via Squarespace, indicating a reliable infrastructure. Performance is moderate with no obvious blocking scripts or heavy resources. Mobile optimization and accessibility are good, with responsive design and ARIA roles used in custom components. SEO is basic with a proper title and viewport meta tag but lacks Open Graph or structured data. No CMS or third-party frameworks detected. The site uses a Cloudflare Insights beacon for minimal analytics. Overall, the technical implementation is solid but could benefit from enhanced SEO and security features.
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.
