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

Chatgo is a small Czech technology company providing a Messenger live chat widget service tailored for websites and e-commerce shops, enabling brands to communicate with customers via Facebook Messenger. Their solution includes chatbot automation, offline messaging modes, and integration with popular Czech e-commerce platforms such as Shoptet and Upgates. The website is professionally designed using WordPress and the Divi theme, with clear navigation and GDPR compliance features. Technically, the site uses modern web technologies and plugins but could improve security headers and update legacy libraries like jQuery. The security posture is adequate with HTTPS and cookie consent but lacks explicit security policies or incident response contacts. WHOIS data is unavailable, limiting domain trust analysis, but the business presence and partner ecosystem suggest legitimacy. Overall, the site is well-positioned in its niche with room for technical and security enhancements.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

      Third-party services without privacy policy

      Detected services: Facebook, Google APIs

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

  2. 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"

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

Chatgo operates in the technology and e-commerce sectors, targeting website owners and online shops seeking to enhance customer engagement through Messenger chat. Their SaaS business model leverages partnerships with major Czech e-commerce platforms, providing integrations and add-ons to expand reach. The company emphasizes ease of use, GDPR compliance, and customer relationship building via personalized chat interactions. The presence of multiple partner logos and a dedicated support email indicates a professional and established operation. However, the lack of detailed WHOIS data and absence of phone contact may limit some trust signals. The company appears focused on growth within the Czech market with strategic partnerships and product extensions like photo reviews.

Security posture

The website enforces HTTPS and implements GDPR cookie consent, reflecting a baseline security and privacy posture. However, it lacks several recommended security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate common web attacks. The use of an outdated jQuery version may expose the site to known vulnerabilities. No explicit security policy, incident response contacts, or vulnerability disclosure mechanisms are present, which are important for mature security governance. No sensitive data exposure or obvious vulnerabilities were detected in the content. Overall, the security posture is moderate but could be significantly improved by adopting best practices and transparency measures.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Upgrade jQuery and other JavaScript libraries to the latest secure versions to mitigate known vulnerabilities.
  3. Publish a clear security policy and provide incident response contact information to enhance trust and readiness.
  4. Add a security.txt file or vulnerability disclosure page to encourage responsible reporting of security issues.
  5. Consider adding phone contact information and more detailed company registration data to improve business credibility.

Technical notes

Notes

The website is built on WordPress 5.2.23 with the Divi theme and several plugins including ChatGo for live chat and Moove GDPR Cookie Compliance. It uses jQuery 1.12.4, FontAwesome 5.15.4, and integrates external resources from Google Fonts and Cloudinary. The site is mobile optimized with responsive design and includes SEO meta tags and Open Graph data. Performance is moderate with some room for optimization. The technical stack is modern but some components like jQuery are outdated, posing potential security risks. Hosting provider details are not evident from the content. Overall, the technical infrastructure supports the business needs but requires updates and security hardening.
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.
