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

nanoshinono.me is a personal portfolio website of a young developer known as prefetcher, based in Poland. The site showcases various niche projects related to retro computing culture, multiplayer games, online radio, and music streaming. The business model is primarily personal branding and project promotion within a niche community. The website is modest in scale and targets enthusiasts of 1990s-2000s computing aesthetics and indie game development. Technically, the site is built with standard HTML, CSS, and JavaScript, hosted behind Cloudflare DNS services. It lacks advanced frameworks or CMS platforms and shows basic mobile optimization and accessibility. Performance is moderate with no detected tracking or advertising services, indicating a lightweight footprint. From a security perspective, the site uses HTTPS and domain-level protections but lacks important security headers and privacy compliance mechanisms such as privacy and cookie policies. No forms or data collection points are present, reducing attack surface but also limiting user interaction. The presence of links to an NSFW site without warnings impacts content safety ratings. Overall, the security posture is average with room for improvement in headers and compliance. The overall risk is moderate, with no critical vulnerabilities detected but lacking in privacy and security best practices. Strategic recommendations include implementing security headers, adding privacy and cookie policies, improving mobile and accessibility features, and clearly labeling NSFW content. These steps would enhance trust and compliance while maintaining the site's niche appeal.

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 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

The website represents a small-scale personal brand focused on software development and retro internet culture. Its market position is niche, targeting enthusiasts and developers interested in Y2K-era aesthetics and indie projects. The business model is non-commercial, centered on portfolio display and community engagement. Revenue streams are not evident, suggesting a hobbyist or passion project. The site links to multiple related projects and platforms, indicating an ecosystem of personal and community-driven services. Growth indicators are limited but consistent with a stable personal brand. No formal partnerships or parent companies are identified, and the use of privacy protection in WHOIS is typical for individual operators.

Security posture

The security maturity level is basic to moderate. HTTPS is enforced, and domain registration includes standard EPP protections. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, limiting transparency. The lack of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. No forms or user input reduce risk exposure but also limit engagement. The presence of NSFW linked content without warnings could pose reputational risks. Overall, the site would benefit from enhanced security controls and compliance documentation to improve its security culture and readiness.

Recommendations

  1. Implement essential security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Add clear privacy and cookie policies with GDPR compliance statements and consent mechanisms.
  3. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Improve mobile responsiveness and accessibility to enhance user experience and compliance.
  5. Clearly label or segregate NSFW content links to protect general audience users and maintain trust.

Technical notes

Notes

The website uses a simple technology stack consisting of HTML5, CSS3, and JavaScript without reliance on frameworks or CMS. Hosting is via Cloudflare DNS with no visible CDN or advanced platform usage. Performance is moderate with basic SEO meta tags present. Accessibility and mobile optimization are minimal but functional. The site lacks modern security headers and privacy compliance features, indicating technical debt in security and compliance areas. There are no forms or dynamic content, reducing complexity but also limiting interactivity. Opportunities exist to modernize the tech stack with frameworks or CMS for scalability and to implement automated compliance and security tools.
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.
