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

OpenTools.ai is a technology platform providing a comprehensive directory and ranking of over 10,000 AI tools, curated by a large community of users. The website targets a broad audience interested in discovering and comparing AI tools, positioning itself as a leading resource with millions of monthly visitors. Technically, the site is built on modern frameworks such as Next.js and React, hosted with Cloudflare DNS and CDN services, and integrates analytics tools like PostHog and Google Tag Manager. The site demonstrates good performance, mobile optimization, and SEO practices. However, it lacks visible privacy and cookie policies, security headers, and direct contact information, which are areas for improvement. The domain is relatively new, registered in 2023 with privacy protection, which is typical for tech startups. Overall, the security posture is moderate with room for enhancements in policy transparency and security best practices.

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

6 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

    • 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

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

OpenTools operates as a community-driven AI tools directory and comparison platform, monetizing through advertising and tool submissions. Its competitive advantage lies in the extensive curated database and active user community. The business model focuses on providing value to AI tool developers and users by facilitating discovery and ranking. The platform's growth is indicated by its 3 million monthly visitors and social media presence. Partnerships and integrations with analytics and advertising platforms support its marketing efforts. The lack of explicit business contact details and policies suggests a lean operational model typical of digital platforms in early growth stages.

Security posture

The website enforces HTTPS and uses domain status locks to prevent unauthorized changes, indicating basic security hygiene. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options reduces its defense-in-depth. No incident response or security policy information is published, limiting transparency. The use of privacy protection for domain registration is justified but obscures registrant details. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Overall, the security maturity is moderate but would benefit from enhanced policies, headers, and incident response readiness.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Implement and publish comprehensive privacy and cookie policies with user consent mechanisms.
  3. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve browser security.
  4. Publish a security policy and incident response contact information to enhance transparency and trust.
  5. Provide clear contact information including company emails or phone numbers to improve business credibility.

Technical notes

Notes

The website uses a modern React and Next.js framework, ensuring good performance and SEO optimization. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. Analytics are implemented using PostHog and Google Tag Manager, enabling detailed user behavior tracking. The site is mobile-optimized and accessible, with a clean and professional design. However, the lack of security headers and privacy policies indicates technical debt in security and compliance areas. No CMS was detected, suggesting a custom or headless architecture. Overall, the technical infrastructure is robust but can be improved with enhanced security and privacy features.
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.
