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

7 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 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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, Twitter, LinkedIn, YouTube, Google Ads

      What to do: Document all third-party data sharing in your privacy policy

  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 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

DNSimple operates in the technology sector with a focus on DNS and domain management automation. Their competitive advantage lies in developer-friendly APIs, automation capabilities, and integration with popular cloud providers. The company serves a diverse customer base including SMBs, agencies, and developers. Their ecosystem includes partnerships and integrations with AWS Route 53, Azure, and GoDaddy. Pricing transparency and customer testimonials indicate a mature business model with growth potential.

Security posture

The website demonstrates good security practices such as HTTPS enforcement, CSRF protection, and clientTransferProhibited domain status. However, DNSSEC is not enabled, which is a notable gap for a DNS provider. There is no publicly available security policy or incident response contact, and no vulnerability disclosure or security.txt file was found. The absence of a cookie consent mechanism despite tracking scripts suggests partial privacy compliance. Overall, the security posture is good but could be improved with enhanced DNS security and transparency.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and trust.
  2. Publish a formal security policy and incident response contact information.
  3. Implement a vulnerability disclosure program or security.txt file.
  4. Add a cookie consent mechanism to comply with privacy regulations.
  5. Explicitly configure and document security headers to improve security posture.

Technical notes

Notes

The website uses a modern technology stack including JavaScript frameworks, PostHog and Ahrefs analytics, and Drip marketing tools. The presence of Rails UJS scripts suggests Ruby on Rails backend usage. The site is fast, mobile-optimized, and SEO-friendly with proper meta tags and structured data. No CMS detected, indicating a custom or proprietary platform. The technical infrastructure supports a high-quality user experience with good accessibility and performance. Opportunities exist to improve security headers and DNS security configurations.
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.
