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

DnesniObed.cz is an online platform focused on aggregating daily and lunch menus from restaurants primarily in Prague and its surroundings. It serves as a valuable resource for users seeking up-to-date meal options, restaurant details, and ordering capabilities. The platform also highlights gastronomic events, enhancing its appeal to food enthusiasts. The website demonstrates a solid market position within its niche, catering to a local audience with a medium-sized operational scale. Technically, the website employs a combination of Bootstrap 3.3.7, jQuery, Font Awesome, and lazy loading techniques to deliver a responsive and user-friendly experience. Integration with Google Analytics and Facebook Pixel indicates a moderate level of digital marketing maturity. While the site is mobile-optimized and SEO-friendly, some technical improvements such as updating libraries and enhancing accessibility could be beneficial. From a security perspective, the site uses HTTPS and avoids exposing sensitive data in its HTML. However, the absence of security headers and privacy/cookie policies suggests gaps in compliance and security best practices. The lack of WHOIS data reduces domain trustworthiness, although the website content and external references support its legitimacy. Overall, DnesniObed.cz presents a functional and relevant service with room for improvement in privacy compliance and security posture. Strategic enhancements in these areas would strengthen user trust and regulatory adherence.

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

10 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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

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 · found on this site
  • 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

DnesniObed.cz operates in the hospitality sector, focusing on aggregating and presenting lunch menus from various restaurants in Prague. Its business model revolves around providing a centralized platform for users to discover, compare, and order meals, potentially generating revenue through partnerships or promotional services for restaurants. The platform's competitive advantage lies in its localized focus and comprehensive daily menu updates. The presence of promotional and event subdomains indicates an ecosystem approach to engaging both restaurants and customers. Growth indicators include a sizable restaurant listing and active content updates. The company targets local consumers, including office workers and residents seeking convenient lunch options. Partnerships with restaurants and event organizers enhance its market presence.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and no sensitive data is visibly exposed. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection indicates potential vulnerabilities to common web attacks. The site lacks publicly available security or incident response policies, which may impact its readiness to handle security incidents. Privacy compliance is weak due to missing privacy and cookie policies, raising concerns under GDPR. The use of third-party analytics and tracking scripts is standard but should be accompanied by transparent user consent mechanisms. Overall, while no critical vulnerabilities are evident, improvements in security headers, privacy policies, and incident response preparedness are recommended.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear user consent mechanisms to ensure GDPR compliance.
  2. Add essential security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against web attacks.
  3. Regularly update third-party libraries and frameworks to their latest secure versions to mitigate vulnerabilities.
  4. Develop and publish a security incident response policy and contact channels to improve transparency and readiness.
  5. Enhance website accessibility features to improve user experience for all visitors, including those with disabilities.

Technical notes

Notes

The website uses a moderately modern technology stack including Bootstrap 3.3.7, jQuery 3.2.1, Font Awesome 4.4.0, and lazy loading for images, which supports responsive design and performance optimization. Analytics and marketing tools like Google Analytics and Facebook Pixel are integrated for user tracking and marketing insights. The site is mobile-optimized and SEO-friendly with proper meta tags and Open Graph data. However, some libraries are outdated, which could pose security and compatibility risks. Performance is moderate, with asynchronous loading of scripts improving load times. Accessibility is basic and could be improved. No CMS is detected, suggesting a custom or static site architecture. Hosting provider details are not available. Overall, the technical infrastructure is solid but would benefit from modernization and enhanced security 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.
