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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

  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"

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

Corny.cz operates in the retail sector focusing on food/snack products, specifically cereal bars. The brand has a long-standing market presence since 1984, positioning itself as a quality snack provider in the Czech Republic. The business model centers on product branding and consumer retail sales. The website supports brand awareness and product discovery but does not provide direct e-commerce functionality. The company leverages social media channels for marketing and customer engagement. No direct contact emails or phone numbers are provided on the site, which may limit direct customer support visibility. The absence of WHOIS data suggests domain privacy or registry restrictions, which is common but slightly impacts transparency. No certifications or security frameworks are disclosed. The site is professionally maintained with consistent branding and good content quality.

Security posture

The website enforces HTTPS and uses cookie consent management, indicating attention to privacy and security compliance. However, no advanced security headers such as Content-Security-Policy or Strict-Transport-Security were detected, which could enhance protection against common web attacks. There is no visible security or incident response policy, nor contact channels for reporting security issues. No vulnerabilities or exposed sensitive data were found in the HTML content. The use of third-party scripts like Google Tag Manager and Usercentrics introduces some risk but is standard practice. Overall, the security posture is good but could be improved by adding security headers and incident response information to increase trust and resilience.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  2. Publish a dedicated security policy and incident response page with contact information for security issues.
  3. Add visible contact emails and phone numbers for customer support and security reporting.
  4. Regularly audit third-party scripts and dependencies to mitigate supply chain risks.
  5. Enhance accessibility features to comply with standards and improve user experience for all users.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and flexible content management system. It uses modern front-end technologies including SVG for graphics and asynchronous JavaScript loading for performance. Google Tag Manager and Usercentrics are integrated for analytics and privacy compliance. The site is mobile-optimized with responsive design and includes meta tags for SEO. Performance is moderate, with some potential for optimization in loading speed and accessibility. The absence of visible hosting provider information limits infrastructure analysis. Overall, the technical implementation is solid with room for improvements in security and accessibility.
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.
