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

Reddit, Inc. operates one of the largest and most influential social media platforms globally, providing a space for user-generated content, community discussions, and news aggregation. The platform targets a broad audience of internet users seeking diverse content and community engagement. Its business model primarily revolves around advertising and premium memberships, positioning Reddit as a key player in the technology and social media industry since its founding in 2005. Technically, Reddit employs a modern technology stack including React and Node.js, hosted on cloud infrastructure with Cloudflare providing CDN and security services. The website demonstrates excellent performance, mobile optimization, and accessibility, reflecting a mature digital infrastructure. Security best practices are well implemented, with HTTPS enforced and comprehensive security headers present, contributing to a strong security posture. While the website lacks explicit privacy and cookie policies in the provided HTML snapshot, it maintains a high level of trustworthiness and professionalism. The absence of WHOIS data suggests privacy protection for domain registration, which is common for large internet companies. Overall, Reddit presents a low-risk profile with robust technical and security foundations, though improvements in visible privacy compliance documentation could enhance user trust further.

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

Reddit holds a strong market position as a leading social media and community platform, leveraging user-generated content to drive engagement and advertising revenue. Its competitive advantage lies in its vast and active user base, diverse content categories, and community-driven moderation. The business model focuses on monetization through targeted advertising and premium subscription services. Reddit's partnership ecosystem includes major social media and analytics platforms, supporting its marketing and user engagement strategies. Growth indicators include continuous platform enhancements and expanding mobile presence, reinforcing its relevance in the digital media landscape.

Security posture

The security maturity of Reddit is high, with enforced HTTPS, modern security headers, and no visible vulnerabilities in the analyzed content. The platform follows security best practices, minimizing exposure of sensitive data and employing robust infrastructure protections. However, the lack of publicly visible incident response contacts or detailed security policies in the analyzed content suggests room for improvement in transparency and user communication regarding security incidents. Compliance with GDPR and other privacy regulations is not explicitly evident in the provided data, indicating potential gaps in privacy compliance documentation.

Recommendations

  1. Publish clear and accessible privacy and cookie policies on the main website to improve transparency and GDPR compliance.
  2. Implement and publicize an incident response policy and contact channels to enhance security communication and user trust.
  3. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.
  4. Enhance user consent mechanisms for cookies and tracking to align with privacy best practices.
  5. Develop a long-term security strategy focusing on continuous monitoring, user education, and compliance adherence.

Technical notes

Notes

Reddit's technical infrastructure is robust, utilizing modern web technologies such as React and Node.js, supported by cloud hosting and CDN services like Cloudflare. The website demonstrates fast loading times, excellent mobile responsiveness, and good SEO and accessibility features. The use of structured data and meta tags supports search engine visibility. Technical risks are minimal, with no deprecated or vulnerable libraries detected in the analyzed content. Opportunities exist to further optimize privacy compliance and enhance transparency around data collection and security practices.
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.
