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. 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

  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"

      • 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';…

  3. 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

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

The company leverages a multi-faceted business model offering various proxy IP services tailored to different customer needs, including API access and tools for integration. The presence of multiple partner domains and friendly links indicates an active partnership ecosystem. The website content and structure suggest a mature digital presence with clear market positioning in the technology sector. Revenue streams likely include subscription and usage-based billing for proxy IP services. The company provides customer support via phone, email, and online chat, enhancing customer engagement and trust.

Security posture

The website enforces HTTPS and integrates advanced bot detection and captcha services, indicating a moderate to good security posture. However, the absence of visible security headers and explicit security policies, as well as missing incident response and vulnerability disclosure information, highlight areas for improvement. The use of multiple third-party analytics and tracking scripts increases the attack surface and privacy considerations. No critical vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security posture is adequate but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement comprehensive security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options to strengthen defense against common web attacks.
  2. Add explicit cookie consent banners and privacy notices to improve GDPR and global privacy compliance.
  3. Publish a dedicated security policy and incident response contact information to enhance trust and preparedness.
  4. Regularly audit and update third-party scripts to mitigate risks from external dependencies.
  5. Consider obtaining recognized security certifications to boost business credibility and customer confidence.

Technical notes

Notes

The website uses a modern frontend technology stack including Bootstrap, jQuery, and layui frameworks, ensuring responsive design and good user experience. Integration of advanced fingerprinting and bot detection tools demonstrates technical maturity in security monitoring. Performance is moderate with room for optimization. SEO practices are good with proper meta tags and structured navigation. However, no CMS or hosting provider information was detected. Accessibility features are basic and could be improved to meet wider standards. Overall, the technical infrastructure supports the business needs effectively but can be enhanced for scalability and security.
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.
