Medium risk. 8 critical or high findings in Security headers, GDPR outside view and 1 other check.

Security score

67/100

Risk levelMedium

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

The website www.mouser.com is currently inaccessible due to a security challenge page implemented via a captcha interstitial from captcha-delivery.com, indicating the presence of a Web Application Firewall (WAF) or bot mitigation system. This prevents extraction of meaningful content, metadata, or business information from the site. The WHOIS lookup for the domain failed to return any registration data, showing 'No match for domain', which is unusual for a well-known commercial entity and suggests either privacy protection or an issue with the WHOIS server response. Due to these factors, a comprehensive analysis of the website's business, technical infrastructure, and security posture is not possible at this time.

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. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

No business intelligence data could be extracted due to the blocked content and missing WHOIS information. The domain is known in the electronics distribution industry, but no direct evidence from the provided data supports detailed insights into market positioning, partnerships, or operational details.

Security posture

The security posture cannot be fully assessed because the site is protected by a WAF or bot mitigation system that blocks content access. No security headers or SSL configuration details are available. The presence of a captcha challenge indicates an active security control to prevent automated access, which is a positive security measure. However, the lack of accessible data limits evaluation of compliance, incident response, or vulnerability management.

Recommendations

  1. Provide access to a non-blocked version or allow authenticated scans to enable full security and content analysis.
  2. Ensure WHOIS data is publicly available or accessible for verification to improve domain trustworthiness.
  3. Implement and expose clear privacy, cookie, and security policies accessible without security challenges.
  4. Publish contact and incident response information to enhance transparency and compliance.
  5. Regularly audit and document security headers and SSL configurations for external verification.
Site observations

Automated reading of the public site. Ratings are indicative.

Generic detected. Website content is blocked by a security mechanism showing a captcha interstitial from captcha-delivery.com, indicating a WAF or bot mitigation in place. These observations may be incomplete. For a fuller analysis, contact guard@offseq.com.

Analytics and tracking

Site quality

Key observations

  1. Website content is inaccessible due to a captcha security challenge.
  2. No metadata, forms, or business content available for analysis.
  3. WHOIS data is missing or unavailable, limiting domain trust analysis.
  4. External scripts are from captcha-delivery.com indicating bot mitigation.
  5. No contact information or policies detected in the provided HTML.
  6. No SEO or accessibility data available due to blocked content.
Technical notes

Notes

The technical infrastructure includes a captcha-delivery.com script and iframe for bot mitigation, indicating use of third-party security services. No CMS, hosting provider, or technology stack details are discernible from the blocked content. The site appears to use minimal HTML with inline styles and scripts focused on security checks. Performance, SEO, and accessibility cannot be evaluated due to content blocking.
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.
