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, Facebook, YouTube, Google APIs

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

  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 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';…

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Bistro.sk operates as an important entity within the e-commerce sector, focusing on food delivery services in Slovakia. Its business model revolves around aggregating local restaurants and stores to provide consumers with a seamless online ordering experience. The company benefits from being part of the global Takeaway.com Group, which provides strategic advantages such as shared technology infrastructure, brand recognition, and operational expertise. Revenue streams likely include commissions from partner restaurants and delivery fees. The target customer segment includes Slovak consumers seeking convenient food delivery options. The presence of a loyalty program, extensive restaurant partnerships, and active social media engagement indicate a growth-oriented strategy. The company also encourages partnerships and courier recruitment, suggesting a scalable operational model. Overall, Bistro.sk is positioned as a leading player in the Slovak food delivery market with strong parent company backing.

Security posture

The security posture of Bistro.sk is robust, with HTTPS enforced site-wide and multiple security headers implemented to protect against common web vulnerabilities. The site uses strict referrer policies and content security policies to mitigate risks. No exposed sensitive information or vulnerable libraries were detected in the HTML content. The presence of secure forms with proper ARIA attributes indicates attention to secure data collection practices. However, the absence of a dedicated security policy page and explicit incident response contact channels limits transparency. The company does maintain a bug bounty program and an ethics hotline, which are positive indicators of a proactive security culture. Compliance with GDPR is evident through privacy policies and cookie consent mechanisms. Overall, the platform exhibits a mature security posture suitable for its business operations but could improve by publishing more detailed security governance information.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact information, such as security@ or abuse@ email addresses.
  3. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance transparency on data retention policies and user data handling.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

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.
