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

Mikrosvín Mikulov is a well-established winery based in the Czech Republic, specializing in producing high-quality wines from the Mikulov wine region. The company emphasizes tradition, terroir, and craftsmanship, with a strong focus on heritage and quality. Their website showcases their history, production methods, key personnel, and numerous prestigious awards, positioning them as a reputable player in the regional wine market. The target audience includes wine consumers, hospitality businesses, and distributors primarily within the Czech Republic. Technically, the website uses modern JavaScript libraries such as jQuery, Google Tag Manager, and Google reCAPTCHA v3, indicating a moderate level of digital maturity. The site is mobile-optimized, accessible, and SEO-friendly, with a cookie consent mechanism supporting GDPR compliance. Security posture is good with HTTPS enforced and spam protection on forms, but lacks visible security headers and explicit security policies. The absence of WHOIS data reduces domain trustworthiness, though the website content and social media presence support legitimacy. Overall, the site is professional and trustworthy but could improve 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.

Priority findings

6 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

      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, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Mikrosvín holds a strong market position as an award-winning winery with a rich history and a clear focus on quality and tradition. Their business model revolves around wine production and sales, targeting both private consumers and commercial clients such as restaurants and clubs. The company leverages storytelling and personal narratives to engage customers, enhancing brand loyalty. Their digital presence includes active social media channels and a professional website, supporting marketing and customer engagement. The lack of WHOIS data is a notable gap but does not overshadow the evident operational maturity. The company appears medium-sized with a focused sector in wine production, operating primarily in the Czech Republic. Their partnership ecosystem is not explicitly detailed on the site, and no related or subsidiary domains were identified.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and the use of Google reCAPTCHA v3 to protect forms from spam and abuse. Cookie consent is implemented with granular user preferences, supporting GDPR compliance. However, the absence of visible security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a weakness that could expose the site to certain web-based attacks. No security or incident response policies are published, and no vulnerability disclosure or security.txt files are present, limiting transparency for security researchers. The lack of WHOIS data also raises questions about domain registration legitimacy. Overall, the security posture is adequate but could be strengthened by implementing recommended headers, publishing security policies, and improving domain registration transparency.

Recommendations

  1. Implement standard security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Publish explicit privacy and security policies, including incident response and vulnerability disclosure information, to improve transparency and compliance.
  3. Verify and update WHOIS domain registration information to ensure legitimacy and build trust.
  4. Consider adding a security.txt file to facilitate responsible vulnerability reporting.
  5. Enhance contact information by providing verified company email addresses for customer and security communications.

Technical notes

Notes

The website uses a modern but relatively simple technology stack including jQuery 3.4.1, Google Tag Manager, and Google reCAPTCHA v3. It employs CSS for styling and includes a cookie consent library from Superkoders. The site is mobile-optimized and accessible, with good SEO practices such as meta tags and structured data (JSON-LD) for organization and website schema. Performance is moderate, with preloading of fonts and images to improve load times. No CMS or hosting provider information is directly detectable. The site uses Google services for analytics and spam protection, indicating reliance on third-party platforms for key functionalities. Technical debt appears low, but improvements could be made in security header implementation and domain registration transparency.
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.
