Risk levelHigh

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

Mouser.cz is a small Czech IT service provider specializing in custom development and management of enterprise information systems, web applications, and network infrastructure. The company offers services including domain registration, web hosting management, LAN network construction, and computer repairs. The website clearly states it is not affiliated with the global Mouser Electronics company, reducing brand confusion. The technical infrastructure is based on PHP, MySQL, HTML5, and JavaScript, hosted likely with WEDOS, a Czech hosting provider. The website is basic in design and content, with minimal SEO and accessibility features. Security posture is weak, with no detected HTTPS or security headers, and no published privacy or cookie policies, indicating compliance gaps. Contact information is clearly provided, but no forms or social media presence is evident. Overall, the site is functional but lacks modern security and privacy best 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.

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

10 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

  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 Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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.

Dark web exposure

Add-on

Leaked records that mention mouser.cz, from OffSeq Breach.

Technical appendix

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

Business context

Business profile

Mouser.cz operates as a local IT service provider targeting businesses needing tailored software and network solutions. Its competitive advantage lies in offering a broad range of IT services including custom software development and network management on Windows platforms. The business model is service-based, focusing on direct client engagements rather than e-commerce or product sales. The domain age of over a decade supports business stability. The explicit disclaimer about no affiliation with Mouser Electronics suggests awareness of potential brand confusion and a proactive approach to transparency. The absence of advanced digital marketing or analytics tools indicates a modest digital maturity level. Growth potential may be limited by the small scale and basic online presence.

Security posture

The website's security posture is currently weak. There is no evidence of HTTPS usage or SSL certificates, which is a critical security flaw. No security headers are present to mitigate common web vulnerabilities. The absence of privacy and cookie policies indicates non-compliance with GDPR and related regulations. No incident response or vulnerability disclosure information is provided, limiting transparency and preparedness. The site does not appear to collect user data via forms, reducing some risk, but also limiting engagement capabilities. Overall, the security maturity is low, exposing the business to potential risks including data interception and regulatory penalties.

Recommendations

  1. Implement HTTPS with a valid SSL certificate to secure all website traffic.
  2. Publish comprehensive privacy and cookie policies to ensure GDPR compliance.
  3. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Establish a vulnerability disclosure policy and provide incident response contact information.
  5. Improve website design for better mobile optimization and accessibility to enhance user experience.

Technical notes

Notes

The website uses a traditional LAMP-like stack with PHP and MySQL, combined with HTML5 and JavaScript for frontend. Hosting and domain registration are managed by WEDOS, a Czech provider. The site is basic in design and lacks modern CMS or frameworks. Performance is moderate but could benefit from optimization and mobile responsiveness improvements. No analytics or tracking scripts were detected, indicating minimal data collection. The absence of security headers and HTTPS is a significant technical risk. The site does not use any known CMS or frameworks, suggesting custom or minimalistic development. Technical debt appears moderate given the dated platform references (Windows Server 2012 R2, Exchange 2016). Modernization opportunities include adopting HTTPS, improving frontend responsiveness, and implementing security best practices.
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.
