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

Chester's Garden is a personal digital garden and portfolio website showcasing the projects, hobbies, writings, and reading interests of Chester, a developer and creative individual. The site targets a general audience interested in personal projects and creative content. It operates as a personal brand platform rather than a commercial business. Technically, the website is built using modern web technologies including Next.js and React, hosted on Vercel, and uses Supabase for media storage. The site is fast, mobile-optimized, and well-structured with good SEO practices. Security-wise, the site enforces HTTPS and avoids forms, reducing attack surface, but lacks explicit security headers and privacy policies. No contact information or incident response channels are provided, limiting transparency and compliance. Overall, the site is safe, professional, and trustworthy but would benefit from improved privacy compliance and security best practices.

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 a personal brand rather than a commercial entity, focusing on sharing Chester's projects and interests. It leverages partnerships such as Mobbin, indicated by referral links. The business model is content sharing and personal branding without direct monetization visible. The target audience includes technology enthusiasts and individuals interested in digital gardens and creative hobbies. The site shows growth indicators through active content updates and social media presence. The partnership ecosystem is limited but includes relevant project collaborations. Strategic observations suggest opportunities to enhance professionalism by adding privacy and security policies and contact channels.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible sensitive data exposure. The absence of forms reduces risk of input-based vulnerabilities. However, the lack of security headers such as Content Security Policy and HSTS is a gap. No vulnerability disclosure or incident response information is provided, which limits readiness for security incidents. Compliance with GDPR and other privacy regulations is weak due to missing privacy and cookie policies. The security culture appears informal, consistent with a personal site, but could be improved by adopting standard security practices and transparency measures.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to improve compliance and user trust.
  2. Add security headers including Content Security Policy, HSTS, and X-Frame-Options to enhance security posture.
  3. Provide clear contact information or a dedicated security contact for incident response and vulnerability reporting.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible security communication.
  5. Regularly review and update third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern and performant technology stack centered on Next.js and React, hosted on Vercel with Supabase for media storage. The site is well-optimized for mobile and SEO, with fast loading times and clean code structure. There is no evidence of technical debt or outdated technologies. The absence of forms reduces complexity and security risks. However, the site lacks explicit security headers and privacy compliance features, which are technical gaps that should be addressed. Overall, the technical infrastructure is solid and supports a high-quality user experience.
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.
