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

linkinbio.fun is a niche SaaS platform launched in 2023 that provides a specialized link-in-bio tool tailored for OnlyFans and adult content creators. The service aims to simplify content promotion and maximize revenue through features like OnlyFans integration, fan engagement tools, NSFW-friendly URLs, analytics, and monetization options. The website is built on WordPress and leverages modern plugins and technologies such as Yoast SEO, Rank Math, Google Tag Manager, and React for enhanced user experience and analytics. Hosting is provided by Hostinger with domain privacy protection enabled. From a security perspective, the site enforces HTTPS and uses Cloudflare DNS but lacks DNSSEC and important security headers, which could be improved. Privacy compliance is basic, with only a minimal privacy policy reference and no cookie consent mechanism. Contact information is limited to a newsletter subscription form, with no direct email or phone contacts visible. No incident response or vulnerability disclosure information is provided. Overall, the website presents a professional and functional platform with good content quality and technical implementation. However, privacy and security practices could be enhanced to improve trust and compliance. The domain registration is privacy protected but consistent with the business launch timeline and industry norms. The site is accessible without WAF or blocking mechanisms, allowing full content analysis.

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

3 findings rated critical or high. Fix these first.

  1. 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

  2. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

linkinbio.fun targets a specialized market segment of adult content creators and influencers, particularly those on OnlyFans. Its competitive advantage lies in offering integrated fan engagement and monetization tools within a mobile-optimized link-in-bio platform. The business model is subscription or freemium SaaS, focusing on maximizing creator revenue and simplifying marketing. The platform integrates with popular social media and content platforms, enhancing reach and monetization potential. Growth indicators include active use of marketing tools like newsletter subscriptions and analytics tracking. The company operates independently with no parent or subsidiaries identified. Strategic observations suggest focusing on expanding privacy compliance and direct contact channels to build greater trust and market credibility.

Security posture

The security posture of linkinbio.fun is moderate. HTTPS is properly configured, and domain transfer is restricted, which are positive indicators. However, the absence of DNSSEC and security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security robustness. No explicit security or incident response policies are published, and no vulnerability disclosure or security.txt files are present. The site uses modern JavaScript libraries and WordPress plugins, but no known vulnerable versions were detected in the provided data. Privacy compliance is minimal, lacking cookie consent mechanisms and comprehensive privacy policies. The limited contact information and lack of security contact channels may hinder incident response effectiveness. Recommendations include implementing security headers, enabling DNSSEC, publishing security policies, and enhancing privacy compliance to strengthen the security posture.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements and implement a cookie consent mechanism.
  4. Add explicit contact information including security and abuse contacts to improve incident response readiness.
  5. Enhance website accessibility features and navigation clarity to improve user experience and compliance.

Technical notes

Notes

The website is built on a modern WordPress platform using a combination of popular SEO plugins (Yoast SEO, Rank Math), analytics tools (Google Tag Manager), and user engagement plugins (Newsletter Optin Box, Contact Form 7, BetterLinks). The tech stack includes jQuery, React, and MobX, indicating a hybrid approach combining classic and modern JavaScript frameworks. Hosting is provided by Hostinger with Cloudflare DNS servers, suggesting a reliable infrastructure. Performance is moderate with mobile optimization considered good. SEO is well addressed with canonical tags, Open Graph metadata, and structured data in JSON-LD format. However, the site lacks advanced security headers and cookie consent mechanisms, which are technical debts that should be addressed. Overall, the technical infrastructure supports the business goals but has room for security and privacy improvements.
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.
