Their business model focuses on providing customized marketing support and web solutions, including website creation, e-commerce platforms, and web applications. The company emphasizes quality and cost-effective solutions, supported by client testimonials and references, positioning itself as a reliable local service provider in the technology sector. Technically, the website is built on Drupal 7 with jQuery 1.10.2 and integrates Google Analytics for visitor tracking. The site includes a cookie consent mechanism compliant with GDPR principles, although explicit privacy and terms of service pages are not found. The technical infrastructure is moderate in performance and mobile optimization, with room for modernization and security improvements. From a security perspective, the site lacks visible security headers and uses an outdated JavaScript library version, which could pose vulnerabilities.

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

8 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, Google APIs

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

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

Internet Stream s.r.o. operates in the technology sector, focusing on SEO and web application development services for businesses and individual clients. Their competitive advantage lies in customized solutions tailored to client needs, emphasizing cost efficiency and quality. The company leverages client references and testimonials to build trust and attract new customers. Their market presence appears localized within the Czech Republic, targeting small to medium-sized enterprises seeking digital marketing and web development support. The business model is service-oriented with revenue streams from project-based engagements. Partnerships with client websites and references indicate a collaborative ecosystem, although no formal subsidiaries or parent companies are identified.

Security posture

The current security maturity level is moderate with basic security practices such as cookie consent and HTTPS usage implied but not fully verified. The use of Drupal 7 and an outdated jQuery version introduces potential vulnerabilities. The absence of security headers like Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No explicit security or incident response policies are published, and no contact channels for security incidents are provided. GDPR compliance is partially addressed through cookie consent but lacks comprehensive privacy policy documentation. Overall, the security posture requires enhancements to meet modern standards and reduce risk exposure.

Recommendations

  1. Implement and enforce modern security headers including CSP, HSTS, and X-Frame-Options.
  2. Upgrade jQuery and other JavaScript libraries to current secure versions to mitigate vulnerabilities.
  3. Publish a comprehensive privacy policy and terms of service to improve transparency and compliance.
  4. Add explicit contact information for security incidents and data protection officer if applicable.
  5. Verify domain WHOIS registration details and ensure domain registration transparency.

Technical notes

Notes

The website is built on Drupal 7 CMS with jQuery 1.10.2 and uses Google Analytics for visitor tracking. The site includes multiple CSS and JavaScript resources, including Colorbox for UI elements. Performance is moderate with basic mobile optimization and accessibility features. The site uses a cookie consent mechanism with detailed user controls, indicating attention to privacy compliance. However, the use of an older CMS version and outdated JavaScript libraries suggests technical debt and potential security risks. No hosting provider information is detected. SEO optimization is good with proper meta tags and structured navigation. Opportunities exist to modernize the tech stack and improve 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.
