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

5 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: Google Analytics, Facebook, LinkedIn, YouTube

      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

  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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

ComSource holds a solid position in the Czech IT security market, leveraging deep expertise in cybersecurity, networking, and data analytics. Their business model focuses on service delivery and training, targeting sectors with high security demands such as critical infrastructure and healthcare. The company demonstrates transparency with client references and a clear ownership structure. Their partnership ecosystem includes support portals and industry collaborations. Growth indicators include active content updates, social media engagement, and event participation. The company emphasizes education and innovation, positioning itself as a trusted advisor in IT security.

Security posture

The website and company exhibit a mature security posture with enforced HTTPS, cookie consent compliance, and use of Google reCAPTCHA. However, the absence of explicit privacy policy and terms of service pages, as well as missing security headers like Content-Security-Policy, represent compliance and security gaps. No visible vulnerabilities or exposed sensitive data were detected. Incident response and vulnerability disclosure information are not publicly available, which could be improved to enhance trust and readiness. Overall, the security culture appears proactive but could benefit from formalized policies and transparency.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve compliance and user trust.
  2. Configure Google Analytics properly or remove the plugin to avoid misleading tracking indications.
  3. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear incident response and vulnerability disclosure contact information.
  5. Enhance accessibility features to meet higher compliance standards and improve user experience.

Technical notes

Notes

The website is built on WordPress 6.8.3 with Yoast SEO and CookieYes for cookie management, indicating a modern CMS platform with SEO and privacy considerations. The tech stack includes jQuery, Slick carousel, and Lexybox for UI components. Hosting is provided by Active24, a reputable Czech hosting provider. Performance is moderate with good mobile optimization and responsive design. SEO is well addressed with meta tags, Open Graph, and JSON-LD structured data. Some technical debt is noted in unconfigured analytics and missing security headers. Overall, the infrastructure supports business needs but can be improved for security and 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.
