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

Mousehouse s.r.o. is a Czech-based communication and marketing studio specializing in product development, analysis, solutions, and marketing services for brands, startups, companies, institutions, and campaigns. The company positions itself as a creative partner helping clients build their brand and marketing strategies. The website is professionally designed, targeting business clients primarily in the Czech Republic. Technically, the site uses standard web technologies including jQuery and Google Analytics, with HTTPS enabled ensuring secure connections. However, the absence of privacy and cookie policies indicates compliance gaps. The security posture is moderate with no critical vulnerabilities detected, but security headers and incident response information are missing. Overall, the domain WHOIS data is unavailable, which reduces trustworthiness from a domain registration perspective but the website content and contact details suggest a legitimate business presence.

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

8 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

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

Mousehouse operates as a small marketing and communication service provider focused on the Czech market. Its business model revolves around offering tailored marketing solutions including advertising campaigns, brand identity, PR, and digital marketing. The company targets businesses and organizations seeking to enhance their communication and marketing efforts. The website content is consistent and professional, supporting a credible market position. The lack of WHOIS data and absence of certifications or trust badges suggest opportunities to strengthen business credibility. The company does not appear to have subsidiaries or partners listed on the site. Marketing tools like Google Analytics are used for performance tracking. Growth indicators or founding year are not disclosed.

Security posture

The website employs HTTPS, which is a fundamental security measure. However, no advanced security headers such as Content-Security-Policy or X-Frame-Options are detected, which could improve protection against common web attacks. The contact form includes client-side validation but lacks visible anti-CSRF tokens or CAPTCHA mechanisms. No security policies, incident response contacts, or vulnerability disclosure programs are published, indicating limited transparency in security governance. The absence of WHOIS data is a concern for domain legitimacy verification. Overall, the security posture is moderate but could be enhanced by implementing best practices and publishing relevant policies.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to improve GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance web security.
  3. Publish incident response and vulnerability disclosure information to increase transparency and trust.
  4. Regularly update JavaScript libraries and dependencies to mitigate potential vulnerabilities.
  5. Consider registering WHOIS data publicly or using a verified privacy protection service to improve domain trustworthiness.

Technical notes

Notes

The website uses a traditional tech stack with jQuery 1.12.4 and Google Analytics for tracking. The presence of mod_pagespeed indicates some performance optimization efforts. The site is mobile responsive with good navigation and clear structure. However, accessibility features are basic and could be improved. No CMS or hosting provider information is evident from the source. Performance is moderate with some optimization but could benefit from modern frameworks or CDN usage. SEO is basic with meta description present but no Open Graph or JSON-LD structured data detected. Overall, the technical implementation is solid for a small business site but has room for modernization and enhanced accessibility.
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.
