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

Captcha, Inc. operates the BotDetect CAPTCHA Generator website, offering a self-hosted CAPTCHA solution designed for privacy-conscious organizations and developers. The company emphasizes compliance with accessibility standards (WCAG, Section 508) and privacy regulations (GDPR, LGPD, CCPA), positioning itself as a privacy-friendly alternative to Google reCAPTCHA. The business model centers on licensing and selling CAPTCHA software with source code access, targeting enterprises and developers needing customizable and compliant CAPTCHA solutions. The website content is detailed, professional, and well-structured, supporting a strong market position in the niche CAPTCHA technology sector. Technically, the website uses a traditional web stack including jQuery and supports multiple backend platforms (.NET, Java, PHP). Hosting is via Hetzner, and the site integrates Google Analytics and Tag Manager for traffic analysis, though it lacks a cookie consent mechanism. Accessibility and SEO optimizations are good, with mobile responsiveness and localization support. However, explicit security headers and a dedicated security policy are absent, representing areas for improvement. From a security perspective, BotDetect's self-hosted approach reduces third-party dependencies and user tracking risks. The site promotes strong privacy and accessibility compliance, but lacks published incident response or vulnerability disclosure policies. No critical vulnerabilities or suspicious elements were detected. WHOIS data confirms domain legitimacy with a long registration history and consistent registrant information. Overall, the website presents a trustworthy, professional CAPTCHA solution provider with a strong emphasis on privacy and compliance. Strategic improvements in security transparency and cookie consent would enhance trust and compliance posture.

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

4 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 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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.

Business context

Business profile

Captcha, Inc. occupies a specialized niche in the CAPTCHA technology market, focusing on privacy, accessibility, and regulatory compliance. Its competitive advantage lies in offering a self-hosted, source-code licensable CAPTCHA solution that avoids third-party tracking and supports multi-language audio CAPTCHAs. The company targets developers and organizations requiring GDPR, LGPD, CCPA, WCAG, and Section 508 compliant CAPTCHA implementations, including government and multinational clients. Revenue streams derive from license sales and upgrades. The company maintains a strong partnership ecosystem with technology frameworks like .NET, Java, PHP, Angular, jQuery, and React. Market presence is supported by over 3000 paying customers and references from major corporations. The website content and product roadmap indicate ongoing development and support, signaling growth and stability in a competitive environment.

Security posture

The security posture of the BotDetect CAPTCHA website and product is solid in principle due to its self-hosted nature, eliminating reliance on third-party CAPTCHA services that track users. The product emphasizes privacy and accessibility compliance, reducing legal and regulatory risks. However, the website itself lacks visible security headers (e.g., CSP, HSTS), published security policies, and incident response information, which are best practices for transparency and trust. The use of Google Analytics introduces moderate user tracking, but no cookie consent mechanism is present, which may pose compliance challenges. No vulnerabilities or exposed sensitive data were detected in the content. Overall, the security maturity is moderate to good, with room for improvement in policy transparency and technical security controls.

Recommendations

  1. Implement and publish comprehensive security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  2. Add a clear security policy page detailing security practices, incident response procedures, and vulnerability disclosure guidelines.
  3. Introduce a cookie consent mechanism to comply with GDPR and other privacy regulations given the use of Google Analytics.
  4. Publish contact information for security incidents, including dedicated security or abuse email addresses.
  5. Enhance SSL/TLS configuration transparency and ensure best practices are followed for encryption and certificate management.

Technical notes

Notes

The website employs a traditional web technology stack with jQuery 1.11.1 and supports multiple backend platforms (.NET, Java, PHP). It integrates with Google Analytics and Tag Manager for traffic analysis. Hosting is provided by Hetzner, a reputable provider. The site is mobile responsive and accessible, supporting multiple languages and localization. However, the site lacks explicit security headers and cookie consent mechanisms. Performance is moderate, with no major issues detected. The site does not use a CMS, reducing attack surface related to CMS vulnerabilities. Overall, the technical infrastructure is stable and mature but could benefit from modernization in security practices and privacy compliance 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.
