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

4 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 platform's market position is as a privacy-first, tracker-free alternative in the niche of userstyle sharing. Its business model is community-driven and open-source, relying on contributions and community engagement rather than monetization through ads or tracking. Key services include userstyle hosting, browsing, syncing, and integration with Stylus. The project is transparent with open-source code on GitHub and licensed under AGPLv3, enhancing trust and collaboration. The absence of direct contact emails or phone numbers suggests a lean operational model relying on web forms and GitHub for communication.

Security posture

Security practices include enforced HTTPS, no tracking or third-party cookies, and clientDeleteProhibited domain status. However, DNSSEC is not enabled, and no explicit security headers were detected in the provided data. The site lacks a published vulnerability disclosure policy and incident response contact, which are areas for improvement. Overall, the security posture is good but could be enhanced by enabling DNSSEC, adding security headers, and publishing clear incident response procedures.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy and X-Frame-Options.
  3. Publish a vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  4. Provide explicit incident response contact information to improve transparency and trust.
  5. Consider adding verified contact emails or phone numbers for business and security inquiries.

Technical notes

Notes

The website uses a custom-built stack with HTML5, CSS3, and JavaScript. It is hosted under a domain registered with Porkbun LLC and Private by Design, LLC. The site demonstrates fast performance, excellent mobile optimization, and good accessibility. SEO is well addressed with proper meta tags and canonical links. The absence of common CMS platforms suggests a custom solution tailored for the userstyle community. The technical infrastructure is modern and well-maintained, with opportunities to enhance security configurations.
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.
