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

ReadMe is a technology company specializing in API documentation and developer experience tools. Their platform enables teams to create, manage, and publish interactive API documentation with features such as Git-style workflows, branching, versioning, and integrated AI assistance. The company targets developers, technical writers, and engineering teams, positioning itself as a mature and established player in the API documentation market. The website reflects a high level of digital maturity, leveraging modern web technologies including React and Next.js, and integrates multiple marketing and analytics tools to optimize user engagement and business insights. Security posture is solid with HTTPS enforced and reputable DNS hosting via Cloudflare, though there is room for improvement in publishing explicit security policies and enabling DNSSEC. Overall, the site is professional, well-designed, and trustworthy, but lacks visible privacy and cookie policies which may impact compliance. Strategic recommendations include enhancing privacy compliance, publishing security and incident response policies, and enabling DNSSEC to strengthen DNS security.

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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

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 a SaaS business model focused on API documentation and developer tools, serving a medium-sized market segment of developers and technical teams. The company benefits from a long-established domain (since 1998) and consistent branding. Their platform offers key competitive advantages such as integrated AI tools, Git-backed documentation workflows, and detailed analytics. The presence of multiple integrations with marketing and analytics platforms indicates a mature marketing ecosystem. No direct contact information or physical addresses are published, which is common for SaaS companies but may affect direct customer trust. The company appears to maintain strong partnerships with major technology providers and uses Cloudflare for DNS and likely CDN services, enhancing performance and security.

Security posture

The website demonstrates a good security posture with HTTPS enforced and domain status set to clientTransferProhibited, preventing unauthorized transfers. DNS is managed by Cloudflare, a reputable provider offering security and performance benefits. However, DNSSEC is not enabled, which is a recommended best practice to prevent DNS spoofing. No explicit security headers were detected in the provided content, and there is no visible security policy or incident response information published on the site. The site uses multiple third-party scripts for analytics and marketing, which increases the attack surface and requires careful management. No vulnerabilities or exposed sensitive data were found in the HTML content. Overall, the security maturity is good but could be improved by publishing security policies, enabling DNSSEC, and adding security headers.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing attacks.
  2. Publish a comprehensive privacy policy and cookie policy with consent mechanisms to improve GDPR compliance.
  3. Add explicit security and incident response policies accessible from the website to increase transparency and trust.
  4. Implement and publish security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Regularly audit third-party scripts and tracking tools to minimize security risks and ensure privacy compliance.

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.
