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 services that enable addressable and measurable advertising across multiple channels. The website content is well-structured, visually appealing, and targets advertisers and publishers seeking scalable identity frameworks. Technically, the site leverages modern frameworks such as Nuxt.js and Tailwind CSS, with Cloudflare as the registrar and DNS provider, ensuring good performance and security. The presence of a cookie consent mechanism indicates awareness of privacy regulations, although explicit privacy and terms of service documents are not found, which is a compliance gap. Security posture is solid with HTTPS and reputable third-party integrations, but lacks published incident response or vulnerability disclosure policies. Overall, the domain registration data aligns well with the business claims, supporting the legitimacy of the site.

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

6 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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

ID5 is positioned as a medium-sized technology company founded in 2016 in Great Britain, specializing in identity solutions for digital advertising. Their business model revolves around providing technology that adapts to industry changes, regulatory shifts, and signal loss to maximize advertising performance. The company targets digital advertising leaders and has partnerships with major ad tech providers like InMobi and Zoho. The website reflects a professional brand with consistent messaging and trust indicators such as client logos and a cookie consent banner. The lack of direct contact information and detailed legal policies may limit some user trust but does not detract significantly from their market presence.

Security posture

The website demonstrates a good security posture with enforced HTTPS, use of Cloudflare DNS and registrar, and integration of a consent management platform. However, it lacks explicit security headers visible in the HTML, published security policies, incident response contacts, or vulnerability disclosure mechanisms. No vulnerabilities or exposed sensitive data were detected in the content. The cookie consent mechanism is comprehensive, indicating compliance efforts. To improve, the company should publish security policies, incident response contacts, and consider a security.txt file to enhance transparency and readiness.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the main navigation or footer.
  2. Add explicit security headers such as X-Frame-Options and X-Content-Type-Options to enhance protection.
  3. Provide clear incident response and vulnerability disclosure contact information, possibly via a security.txt file.
  4. Enhance transparency by including direct company contact emails and phone numbers for support and security.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is built on a modern technology stack including Nuxt.js (Vue.js SSR framework) and Tailwind CSS, ensuring responsive design and good performance. Hosting and DNS are managed via Cloudflare, providing robust infrastructure and security benefits. The site uses third-party consent management and marketing automation tools from InMobi and Zoho, indicating integration with industry-standard services. The HTML is well-structured with proper meta tags for SEO and social sharing. No CMS like WordPress or Drupal is detected, suggesting a custom or framework-based site. Performance and mobile optimization are excellent, with accessibility features present. Technical risks are minimal but could be further reduced by adding missing security headers and formalizing security policies.
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.
