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

Mrkev media s.r.o. operates a professional web design and development agency based in the Czech Republic, specializing in custom websites tailored to client needs. The company has a solid portfolio with over 400 projects since 2009, serving individuals, small businesses, non-profits, and universities. Their services include website creation, online marketing, domain management, and ongoing support. The website is built on WordPress with modern technologies such as Google Analytics, Google Tag Manager, and Facebook SDK integrated for marketing and analytics purposes. The site is mobile-optimized and presents a professional user experience with clear navigation and relevant content. Security posture is good with HTTPS enforced and use of reCAPTCHA on forms, but lacks some security headers and published security policies. WHOIS data is unavailable, which raises concerns about domain registration transparency. Overall, the website is trustworthy and professional but would benefit from improved privacy compliance and security disclosures.

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

11 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

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • OWASP A04:2025
      • ASVS V3.4.1
    • High

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

Mrkev media s.r.o. positions itself as a reliable and experienced web design agency with a focus on custom solutions and long-term client relationships. Their competitive advantage lies in comprehensive service offerings from design to marketing and maintenance. The business model is service-based with revenue likely generated from project fees and ongoing support contracts. The target customers range from individuals to educational institutions, indicating a diverse client base. The presence of multiple client references and portfolio examples supports credibility and market presence. The company operates in the technology sector, specifically digital services, and appears to be a small-sized enterprise with a local market focus. There is no indication of parent or subsidiary companies. The website content and branding are consistent and professional, supporting a positive market reputation.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is properly implemented, and Google reCAPTCHA is used to protect the contact form from spam and abuse. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces the overall security posture. No security or incident response policies are published, and no vulnerability disclosure or security.txt files are present. The lack of WHOIS transparency also detracts from trust. There are no visible vulnerabilities or exposed sensitive data in the HTML content. Compliance with GDPR is not clearly demonstrated due to missing privacy and cookie policies. Incident response readiness and security culture indicators are not evident from the website content.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to improve GDPR compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  3. Publish a security policy and incident response contact information to demonstrate security maturity and readiness.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Verify and update WHOIS registration information to improve domain legitimacy and trustworthiness.

Technical notes

Notes

The website is built on WordPress CMS with jQuery 2.2.4 and integrates Google Analytics, Google Tag Manager, and Facebook SDK for analytics and marketing. The site uses modern SEO practices with Yoast SEO plugin and includes structured data in JSON-LD format for enhanced search engine understanding. Performance is moderate with minified CSS and JS files, though no explicit hosting provider information is available. The site is mobile-optimized and uses responsive design. Accessibility is basic but could be improved. The absence of security headers is a technical risk. Overall, the technical infrastructure is solid for a small web agency but could benefit from security and privacy enhancements.
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.
