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, Google APIs

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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

The company positions itself as a trusted web design and digital marketing service provider in the Czech Republic, targeting small to medium enterprises, corporations, developers, startups, and educational institutions. Their competitive advantage lies in custom, non-template web design, fast loading times, and comprehensive client support. The business model is service-oriented with revenue likely from project-based web development and ongoing marketing consulting. The presence of notable clients and testimonials indicates a solid market reputation. The company leverages multiple marketing and retargeting tools to enhance client acquisition and retention. No parent or subsidiary companies are identified, suggesting an independent operation focused on the Czech market.

Security posture

The website demonstrates a good security posture with HTTPS enforced and secure multi-step forms that include anti-bot hidden fields. Cookie consent is implemented with granular user controls, supporting GDPR compliance. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a gap that could be addressed to improve protection against common web attacks. No security or incident response policies are published, which limits transparency for security concerns. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security maturity is solid but could be enhanced with additional headers and published policies.

Recommendations

  1. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Add a terms of service page to clarify user agreements and legal protections.
  4. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Maintain and regularly audit cookie consent and privacy compliance mechanisms to ensure ongoing GDPR adherence.

Technical notes

Notes

The website uses a proprietary CMS (MySUITU CMS) and modern web technologies including jQuery 3.4.1, Google Fonts, and Typekit for typography. It leverages CDN-hosted CSS and JavaScript assets for performance optimization. Google Analytics and Google Tag Manager are integrated for analytics and marketing purposes, with additional retargeting scripts from Seznam, LinkedIn, and Bing. The site is mobile-optimized with responsive design and fast loading times due to multiple optimizations. Accessibility is good with semantic HTML and clear navigation. No major technical debts or outdated libraries were detected. Opportunities exist to enhance security headers and publish more comprehensive policies to align with best practices.
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.
