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

ID5 Technology Limited operates a professional website focused on providing Adaptive Identity solutions for omnichannel advertising. The company positions itself as a trusted technology provider in the digital advertising ecosystem, offering identity frameworks that enable addressable and measurable advertising across channels. The website demonstrates a modern technical infrastructure leveraging Nuxt.js, Tailwind CSS, and reputable third-party services such as Piwik PRO for analytics and Zoho for marketing automation. Hosting and domain registration are managed via Cloudflare, ensuring robust performance and security. Security posture is strong with HTTPS enforced and clientTransferProhibited domain status, though explicit security policies and incident response contacts are not publicly available. Privacy compliance is partially addressed with a cookie consent banner and GDPR-related consent mechanisms, but lacks a clearly accessible privacy policy and terms of service pages. Overall, the website is professional, trustworthy, and technically mature, serving a specialized audience in the advertising technology sector.

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

5 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 Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 targets digital advertising leaders and professionals seeking scalable identity solutions to address fragmented signals in advertising. Its business model revolves around providing technology platforms that enhance advertising addressability and measurement. The presence of client logos and partnerships with known analytics and consent management providers indicates a strong market position and integration within the advertising ecosystem. Founded in 2016 and based in Great Britain, ID5 Technology Limited maintains consistent domain registration and business information. The company leverages modern web technologies and third-party marketing tools to support its operations and growth. However, the absence of direct contact information and detailed compliance documentation may limit transparency for some stakeholders.

Security posture

ID5.io exhibits a solid security posture with HTTPS enabled and domain status clientTransferProhibited, reducing risk of domain hijacking. The use of Cloudflare as registrar and hosting provider adds a layer of security and performance. The website employs reputable third-party consent management and analytics platforms, indicating attention to privacy and data governance. However, the lack of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. No vulnerabilities or exposed sensitive data were detected in the HTML content. Security headers are implied but not explicitly visible in the HTML source, suggesting potential for improvement. Overall, the security maturity is good but could be enhanced by publishing comprehensive security and incident response documentation.

Recommendations

  1. Publish a comprehensive privacy policy page clearly linked from the website footer or header.
  2. Add terms of service and security policy pages to improve transparency and compliance.
  3. Enable DNSSEC on the domain to strengthen DNS security.
  4. Implement and publicize a vulnerability disclosure policy and security contact email.
  5. Explicitly configure and verify security headers such as Content-Security-Policy and X-Frame-Options.

Technical notes

Notes

The website is built on a modern JavaScript framework (Nuxt.js) with Tailwind CSS for styling, ensuring responsive and performant user experience. Hosting and DNS are managed by Cloudflare, providing robust infrastructure and security benefits. The site integrates third-party services including Piwik PRO for analytics and Zoho for marketing automation, reflecting a mature digital marketing stack. Performance appears fast with optimized assets and asynchronous script loading. Accessibility and SEO optimizations are good, with proper meta tags and Open Graph data present. The technical implementation is solid with room for improvement in explicit security header deployment and enhanced privacy documentation.
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.
