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 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 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 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

Letterboxd holds a strong niche position in the media and entertainment sector, leveraging user-generated content and social networking to engage a dedicated audience. Its competitive advantage lies in its specialized focus on film and a robust community. Revenue streams likely include advertising and Pro subscriptions. The company maintains active social media channels across major platforms, enhancing brand visibility and user engagement. The absence of privacy protection in WHOIS data and consistent domain registration details reinforce business transparency and trustworthiness.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, CSRF protection in forms, and integration of reCAPTCHA to mitigate automated abuse. Security headers are implied but not explicitly visible in the provided data, and DNSSEC is not enabled, representing a minor area for improvement. No vulnerabilities or exposed sensitive data were detected. The lack of a published security policy or incident response information suggests room for enhancing transparency and preparedness. Overall, the security measures align well with industry best practices for a social platform.

Recommendations

  1. Enable DNSSEC to enhance domain name system security.
  2. Publish a dedicated security policy and incident response contact information.
  3. Explicitly implement and verify security headers such as Content-Security-Policy and X-Frame-Options.
  4. Consider adding a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Maintain and regularly audit third-party scripts to minimize potential vulnerabilities.

Technical notes

Notes

The website employs a modern and performant technology stack including React, ES modules, and advanced JavaScript features. It uses Cloudflare for DNS and likely CDN services, contributing to fast load times and global availability. Advertising and analytics integrations are extensive but balanced with privacy considerations such as cookie consent and reCAPTCHA. The site is mobile-optimized and accessible, with good SEO practices evident from meta tags and structured data. No major technical debt or legacy technologies were detected, indicating a well-maintained infrastructure.
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.
