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

7 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 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 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

      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

    • 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

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

Business profile

Comerto holds a strong market position in the Czech Republic's digital marketing sector, leveraging a full-service model that includes web creation, e-commerce solutions, SEO, PPC, and social media campaigns. Their competitive advantage lies in a comprehensive service portfolio, a stable team, and a client-centric approach with active communication. Revenue streams likely derive from project-based web development, ongoing marketing campaigns, and consulting/training services. The company maintains a visible partnership ecosystem through social media and local business listings. Growth indicators include a large client base and active content publishing. Strategic observations suggest a focus on quality service delivery and digital maturity, with opportunities to enhance security transparency and incident response readiness.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and a cookie consent mechanism compliant with GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, security headers such as Content-Security-Policy and X-Frame-Options are not explicitly observed and could be added to strengthen defenses. Incident response and security policy information are absent, indicating potential gaps in transparency and readiness. The site uses third-party analytics and advertising scripts, which are managed with user consent. Overall, the security maturity is good but could benefit from formalized policies and enhanced header configurations to mitigate risks.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Regularly audit third-party scripts and dependencies to identify and mitigate vulnerabilities.
  4. Enhance data protection officer visibility or contact details to align with GDPR best practices.
  5. Maintain and update cookie consent mechanisms to reflect evolving privacy regulations.

Technical notes

Notes

The website is built with modern web standards, utilizing SVG graphics for logos and decorative elements, and integrates Google Analytics, Google Tag Manager, and Facebook Pixel for tracking and marketing. The site is responsive and optimized for mobile devices, with good SEO metadata and structured data (JSON-LD) for enhanced search engine understanding. The CMS appears custom or proprietary, supporting complex content structures and forms. Performance is moderate, with potential for optimization in loading times and script management. Accessibility features are present but could be further enhanced. Hosting provider details are not explicitly identified. Overall, the technical infrastructure supports a professional digital marketing agency's needs with room for incremental improvements.
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.
