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

Flounder.online is a small niche service providing a free web interface and log builder for the Gemini protocol network, a privacy-focused internet protocol. The website targets users of the Gemini network who require simple tools to manage Gemini capsules. The business model is based on offering free services with optional donations via Patreon. The site is modest in scale and content but updated frequently, indicating active maintenance within its community niche. Technically, the website uses basic HTML and CSS without advanced frameworks or CMS, hosted likely via Namecheap. The site is mobile responsive at a basic level and has moderate performance. Security posture is minimal with no advanced security headers or policies detected, and no HTTPS configuration details available from the provided data. Privacy and cookie policies are absent, and no contact or incident response information is provided, limiting compliance and trust signals. Overall, the site is functional and relevant for its audience but lacks formal security and privacy documentation.

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

5 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 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

    • 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 website operates in the technology sector, specifically serving the Gemini protocol community. Its competitive advantage lies in providing a simple, free web interface for Gemini capsules, a niche underserved by mainstream web services. Revenue streams appear limited to donations, indicating a community-supported model. The target customers are technically inclined users of Gemini. The site shows consistent content updates and a focused service offering but lacks broader business information or partnerships. The absence of formal policies and contact details suggests a small-scale operation with limited commercial ambitions. The partnership ecosystem is minimal, with no identified related domains or business partners. Strategic observations suggest potential growth by enhancing security, privacy compliance, and expanding service offerings.

Security posture

The current security maturity level is basic. The website lacks security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security. There is no evidence of HTTPS enforcement or SSL configuration details. No vulnerability disclosure or incident response information is published. The absence of privacy and cookie policies indicates compliance gaps with GDPR and other data protection regulations. No analytics or tracking scripts reduce privacy risks but also limit user behavior insights. The site does not expose sensitive data or show signs of vulnerabilities in the provided content. Overall, the security posture is minimal and could be improved by implementing standard security best practices and formal policies.

Recommendations

  1. Implement and enforce HTTPS with a strong SSL/TLS configuration.
  2. Add and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  3. Deploy security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Create a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Provide clear contact information and incident response channels to enhance transparency and trust.

Technical notes

Notes

The website uses a simple technology stack primarily consisting of HTML5 and CSS, with no detected JavaScript frameworks or CMS. Hosting appears to be via Namecheap based on DNS servers. The site is moderately performant with basic mobile optimization and accessibility features. SEO optimization is minimal but includes basic meta tags such as description and viewport. There is no evidence of analytics or tracking technologies. The site structure is straightforward with clear navigation links. Technical debt is low due to simplicity but modernization opportunities include adding responsive design improvements, accessibility enhancements, and security hardening.
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.
