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

Hidde.blog is a personal blog operated by Hidde de Vries, focusing on web accessibility, web standards, front-end development, and tech ethics. The site serves a niche audience of developers and accessibility enthusiasts, providing insightful blog posts, speaking engagements, and contact opportunities. The business model is primarily personal branding and thought leadership within the technology sector, with a small but consistent audience. The website is well-positioned as a trusted source in its niche with clear author identity and no commercial distractions. Technically, the site is built using the Eleventy static site generator, leveraging modern web standards including custom fonts and SVG graphics. It is hosted with DNS managed by NS1 and uses HTTPS with a good SSL configuration. The site is fast, mobile-optimized, and accessible, with a clean and professional design. SEO practices are good, with proper meta tags and Open Graph data. From a security perspective, the site enforces HTTPS and has domain transfer protection. However, it lacks DNSSEC and security headers such as Content-Security-Policy. No forms or inputs on the homepage reduce attack surface, and analytics are privacy-focused (GoatCounter). There is no explicit security policy or incident response contact published. Privacy compliance is partial, with an accessibility statement but no explicit privacy or cookie policies. Overall, the site is low risk with a strong reputation and good technical hygiene. Recommendations include enabling DNSSEC, adding security headers, publishing privacy and security policies, and implementing cookie consent if cookies are used. These steps would enhance trust and compliance further.

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.

Dark web exposure

Add-on

Leaked records that mention hidde.blog, from OffSeq Breach.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The blog operates as a personal brand platform for Hidde de Vries, targeting web developers and accessibility advocates. It leverages content marketing through blog posts and speaking engagements to build reputation. The business model is non-commercial, focusing on thought leadership rather than direct revenue. The site’s market position is niche but authoritative within web accessibility and ethical technology discussions. The presence of social media links on Mastodon, Bluesky, LinkedIn, and GitHub supports community engagement and professional networking. The lack of advertising and tracking indicates a privacy-respecting approach, appealing to a privacy-conscious audience. Growth potential lies in expanding speaking engagements and content reach.

Security posture

The website demonstrates a mature security posture for a personal blog. HTTPS is enforced, and the domain is protected against unauthorized transfers. The absence of DNSSEC is a minor gap. No security headers were detected, which could improve protection against common web attacks. The site does not collect user data or use intrusive trackers, minimizing privacy risks. Analytics are handled by GoatCounter, a privacy-focused service. No forms on the homepage reduce attack vectors. There is no published security policy or incident response contact, which is a gap for transparency and readiness. Overall, the site is secure but could benefit from enhanced headers and formal security documentation.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a comprehensive privacy policy and cookie consent mechanism if cookies are used.
  4. Add a security policy page with incident response contact information.
  5. Regularly audit third-party scripts and dependencies for vulnerabilities.

Technical notes

Notes

The site uses Eleventy, a modern static site generator, ensuring fast performance and security benefits of static content. Custom fonts and SVG graphics enhance branding and accessibility. The site is mobile-optimized and uses semantic HTML with ARIA attributes for accessibility. Meta tags and Open Graph data support SEO and social sharing. Hosting and DNS are managed by reputable providers. Analytics are minimal and privacy-focused. No CMS or dynamic backend reduces attack surface. Overall, the technical implementation is modern, performant, and well-maintained with opportunities to add security headers and DNSSEC.
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.
