OpenSpeedTest™ is a technology-focused company providing a free, open-source HTML5 internet speed testing tool accessible via any modern web browser without requiring plugins like Flash or Java. Established in 2013, the company targets a broad audience including individual internet users, website and app owners, and enterprise infrastructure operators. Their business model centers on offering free tools supported by advertising and self-hosted deployment options.

Security posture is strong with HTTPS enforcement, comprehensive security headers, and no visible vulnerabilities. Privacy compliance is robust, featuring a detailed consent management platform aligned with GDPR requirements.

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

  • DNS health: did not complete in this scan.
  • 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

Business profile

OpenSpeedTest™ occupies a niche in the internet speed testing market by offering an open-source, browser-based solution that appeals to both end-users and businesses seeking embedded or self-hosted speed testing capabilities. Their competitive advantage lies in the use of HTML5 technology, eliminating the need for plugins, and providing flexible deployment options. Revenue is primarily generated through advertising, supported by Google Adsense and related marketing tools. The company maintains active engagement on major social media platforms, enhancing brand visibility and community trust. The absence of physical address or direct contact emails suggests a lean operational model focused on digital delivery. Strategic partnerships with CDN providers and analytics platforms underpin their technical reliability and marketing effectiveness.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented, including HSTS, X-Content-Type-Options, and Content-Security-Policy. The presence of a comprehensive GDPR-compliant consent management platform indicates strong data protection practices. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a published security policy, vulnerability disclosure program, or incident response contacts represents a compliance gap and potential risk in handling security incidents. The site’s reliance on third-party scripts (Google Analytics, Adsense) necessitates ongoing vigilance to mitigate supply chain risks. Overall, the security maturity is good but could be enhanced by formalizing security governance documentation and incident response mechanisms.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency and readiness.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Add a clear Terms of Service page to define user rights and obligations.
  4. Provide direct company contact emails and phone numbers for support and security inquiries to enhance trust.
  5. Regularly audit third-party scripts and dependencies to minimize security risks from external sources.

Technical notes

Notes

The website is built on a modern, standards-compliant HTML5 and JavaScript stack, utilizing Google Fonts for typography and Google services for analytics and advertising. It is hosted behind Cachefly CDN, ensuring fast content delivery globally. The site is mobile-optimized and accessible, with responsive design and good SEO metadata including Open Graph and Twitter Card tags. No CMS was detected, indicating a custom or static site architecture. Performance is fast with asynchronous loading of scripts and deferred JavaScript execution. The technical implementation is robust with minimal technical debt, though opportunities exist to enhance accessibility further and formalize technical documentation for security and 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.
