ReadMe is a well-established technology company specializing in API documentation and developer experience platforms. Their website offers comprehensive interactive API documentation tools, targeting developers, technical writers, and engineers. The company has a strong market position with enterprise-level clients and provides key services such as API reference hosting, developer portals, API key management, and integrated AI tools for documentation assistance. Technically, the website is built on modern frameworks like Next.js and React, leveraging Cloudflare DNS and various marketing and analytics tools. The site is performant, mobile-optimized, and professionally designed, offering a high-quality user experience.

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

2 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

  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

ReadMe operates in the technology sector, focusing on API documentation and developer tools. Their business model revolves around SaaS offerings for API documentation and developer portals, serving enterprise clients including notable companies like Kalshi, Notion, and Nvidia. The platform supports collaborative documentation workflows and interactive API testing, enhancing developer onboarding and engagement. The company maintains a strong digital presence with customer stories and a blog, indicating active marketing and community engagement. The absence of explicit contact information on the main site suggests a focus on self-service and enterprise sales channels. The use of multiple analytics and marketing tools reflects a mature marketing strategy. No direct partnerships or subsidiaries were identified from the data.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and domain status set to clientTransferProhibited, reducing risk of unauthorized domain transfers. However, DNSSEC is not enabled, which could improve DNS security. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are present, which are important for transparency and trust in enterprise environments. The site uses multiple third-party scripts for analytics and marketing, which increases the attack surface and requires careful management. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Security headers were not explicitly identified, suggesting potential for improvement. Overall, the security posture is good but could be enhanced with published policies and DNSSEC.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies with GDPR compliance details.
  3. Add a dedicated security policy page including incident response contacts and vulnerability disclosure information.
  4. Implement security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  5. Review and minimize third-party scripts to reduce attack surface and improve privacy.

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.
