Risk levelMedium

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

The website 'Mary's Internet Realm' is a personal and hobbyist site created in 2018, featuring casual content including a Tetris game and links to various personal projects and friends' websites. It targets general internet users interested in casual gaming and personal portfolios. The site is small-scale with basic content quality and moderate branding consistency. Technically, it uses standard HTML, CSS, and JavaScript with Cloudflare DNS hosting but lacks advanced frameworks or CMS. Mobile optimization is good, but accessibility and SEO are basic. Security posture is weak due to lack of security headers, DNSSEC, and privacy policies. The domain is privacy protected via a reputable registrar, which is typical for personal sites. Overall, the site is safe and suitable for general audiences but lacks professional security and privacy compliance features.

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. 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';…

  2. 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

This personal website does not represent a commercial business but serves as a personal portfolio and casual gaming platform. It has no clear revenue model or market positioning beyond personal branding. The site links to multiple partner and friend domains, indicating a small network of related personal projects. The absence of business information, certifications, or formal policies suggests a hobbyist approach rather than a commercial enterprise.

Security posture

The security posture is minimal. The site uses HTTPS (assumed but not explicitly confirmed), but DNSSEC is not enabled, and no security headers are detected. There is no evidence of vulnerability disclosure or incident response policies. The lack of privacy and cookie policies indicates non-compliance with GDPR and other privacy regulations. No analytics or tracking scripts reduce privacy risks but also limit business insights. Overall, the site is low risk but would benefit from basic security and compliance improvements.

Recommendations

  1. Enable DNSSEC to improve DNS security and integrity.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add clear privacy and cookie policies to comply with GDPR and enhance user trust.
  4. Provide incident response and vulnerability disclosure information to improve security transparency.
  5. Consider adding analytics with privacy-respecting configurations to better understand user engagement.

Technical notes

Notes

The website is built with basic web technologies (HTML, CSS, JavaScript) and uses Cloudflare for DNS hosting. No CMS or major frameworks are detected, indicating a custom or minimalistic build. The site includes a deferred JavaScript file for the Tetris game. Mobile responsiveness is handled via CSS media queries. Performance is moderate with no heavy external dependencies. Accessibility features are basic, with some ARIA attributes present. SEO is minimal with basic meta tags and Open Graph tags but no structured data like JSON-LD. The domain is registered with Namecheap and uses privacy protection. DNSSEC is not enabled, which is a technical gap. Overall, the technical implementation is functional but basic, with room for modernization and security enhancements.
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.
