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

Nakladatelství Portál is a Czech publishing house website offering content related to books and magazines. The website presents a professional design with a focus on publishing services, targeting a general Czech-speaking audience. The technical infrastructure includes modern frontend technologies such as Bootstrap 4 and Google Tag Manager for analytics and cookie consent management. However, the absence of WHOIS data and registrant information raises concerns about domain legitimacy and transparency. Security posture is moderate with HTTPS likely enabled but lacking visible security headers and explicit privacy or terms of service documentation. Overall, the website is functional and safe but would benefit from enhanced transparency and security practices.

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. 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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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 website positions itself as a publishing entity in the Czech Republic, likely serving readers and subscribers interested in various magazines and books. The business model appears to be content publishing and distribution, though no explicit e-commerce or subscription mechanisms were detected in the provided content. The lack of contact details and corporate information limits the ability to assess market positioning or partnerships. The use of Google Tag Manager indicates some level of marketing and analytics sophistication. Growth indicators and partnerships are not evident from the data.

Security posture

The current security maturity is moderate but incomplete. HTTPS is presumably enabled, but no security headers such as Content-Security-Policy or X-Frame-Options were detected. The absence of privacy policy and terms of service pages reduces compliance with GDPR and other regulations. No incident response or vulnerability disclosure information is available, which limits readiness for security incidents. The website uses cookie consent scripts, indicating some awareness of privacy compliance. Recommendations include implementing security headers, publishing privacy and terms policies, and providing clear contact channels for security incidents.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  2. Implement and verify security headers to enhance protection against common web attacks.
  3. Provide clear contact information including emails and phone numbers for business and security inquiries.
  4. Consider adding a security.txt file or vulnerability disclosure policy to facilitate responsible reporting.
  5. Regularly audit WHOIS data and domain registration to ensure transparency and legitimacy.

Technical notes

Notes

The website uses Bootstrap 4 for responsive design and Google Tag Manager for analytics and cookie consent management. Fonts are loaded from Google Fonts. The site appears moderately optimized for mobile devices and has a clear navigation structure. However, no CMS or backend platform was identified from the HTML content. Performance is moderate with preloading of scripts. Accessibility features are basic but present. The lack of security headers and incomplete metadata reduces overall technical robustness. Hosting provider and SSL configuration details are not available from the provided data.
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.
