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

MVKM s.r.o. is a Czech Republic based marketing agency specializing in performance marketing, PPC campaigns, SEO, social media management, and video production. The company targets businesses seeking measurable marketing results and ROI, positioning itself as a small but professional agency with over 20 satisfied clients and a high client satisfaction rate. The website is modern, well-designed, and mobile-optimized, reflecting a mature digital presence. Technically, the site uses modern frameworks like Next.js and React, with service workers for enhanced performance. Security posture is good with HTTPS and secure forms, but lacks explicit security headers and published security policies. Privacy compliance is limited, with no dedicated privacy policy page found, though a cookie consent banner is present. WHOIS data is unavailable, likely due to privacy protection, which slightly reduces trust but is common for this business type. Overall, the site is professional and trustworthy, with room for improvement in privacy and security transparency.

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

9 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

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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

      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';…

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

MVKM operates in the digital marketing sector, focusing on data-driven marketing strategies to help clients increase revenue and ROI. Their business model revolves around service offerings including PPC campaigns, SEO, social media management, marketing strategy, web development, and video content creation. The company emphasizes measurable results and transparency, supported by client testimonials and aggregate ratings. The target market includes small to medium enterprises in need of marketing growth. The company appears to maintain partnerships with web developers and designers (e.g., matyasherman.cz). Revenue streams likely come from service contracts and consulting. The firm is relatively young, founded in 2020, and maintains a localized presence in Prague, Czech Republic.

Security posture

The website enforces HTTPS and uses secure form inputs, indicating a baseline security posture. However, it lacks visible advanced security headers such as Content-Security-Policy or X-Frame-Options, and does not publish a security policy or incident response contact information. No vulnerabilities or exposed sensitive data were detected in the content. The absence of a privacy policy and security.txt file suggests gaps in compliance and incident readiness. Overall, the security maturity is moderate, suitable for a small marketing agency but with opportunities for improvement to enhance trust and compliance.

Recommendations

  1. Publish a comprehensive privacy policy page detailing GDPR compliance and data handling practices.
  2. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide a security policy and incident response contact information to improve transparency and readiness.
  4. Consider publishing a security.txt file or vulnerability disclosure policy to encourage responsible reporting.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, enabling server-side rendering and optimized performance. It uses service workers for offline capabilities and preloads fonts and images for faster loading. The site is mobile-optimized with responsive design and accessible navigation. SEO is supported by comprehensive meta tags, Open Graph, and Twitter card metadata. No CMS is detected, suggesting a custom or framework-based solution. Hosting provider details are not explicit. Performance is fast with minimal blocking scripts. The technical implementation is robust for a marketing agency website, though adding advanced security headers and privacy features would enhance the overall technical maturity.
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.
