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

ID5 Technology Limited operates a technology platform focused on providing adaptive identity solutions for omnichannel advertising. Their core offering is a scalable identity framework that enables advertisers to address and measure advertising performance across multiple channels, responding dynamically to industry changes and regulatory requirements. The company is positioned as a trusted partner within the digital advertising ecosystem, serving enterprise clients and digital advertising leaders. The website reflects a professional and modern digital presence, leveraging advanced frontend technologies and integrating consent management tools to address privacy regulations. However, explicit privacy policies and terms of service are not directly found on the main site, which could be improved for compliance and transparency. Security posture is solid with HTTPS and Cloudflare infrastructure, but could benefit from additional security headers and published incident response information. Overall, the business demonstrates a credible and mature digital footprint with room for enhanced privacy and security disclosures.

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 an essential technology provider in the digital advertising sector, focusing on identity resolution and measurement solutions. Their business model revolves around providing technology services that enable addressable advertising and measurement across fragmented digital channels. The company targets digital advertising professionals and enterprises seeking to optimize advertising performance in a privacy-conscious environment. The partnership ecosystem includes integrations with major ad networks and marketing automation platforms. The domain age and WHOIS data align well with the company's founding date and business claims, supporting legitimacy. The website content and branding are consistent and professional, reinforcing market trust. Growth indicators include adoption by digital advertising leaders and integration with consent management platforms.

Security posture

The website employs HTTPS with a good SSL configuration and is hosted via Cloudflare, providing a strong baseline for security. The presence of a consent management platform indicates awareness of privacy regulations such as GDPR. However, the absence of DNSSEC reduces DNS security. No explicit security headers were detected in the provided data, and there is no published security policy or incident response contact information, which are important for transparency and trust. No vulnerabilities or exposed sensitive data were identified in the analysis. The security posture is moderate but could be improved by implementing additional security headers, publishing a security.txt file, and providing clear incident response channels.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish comprehensive privacy policy and terms of service pages to improve compliance and user trust.
  3. Add a security.txt file and incident response contact information to facilitate vulnerability reporting and transparency.
  4. Implement additional HTTP security headers such as Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Content-Type-Options.
  5. Enhance accessibility features and provide more explicit contact information for business and security inquiries.

Technical notes

Notes

The website is built using modern web technologies including Nuxt.js and Tailwind CSS, indicating a contemporary and maintainable frontend architecture. Hosting and DNS are managed by Cloudflare, providing performance and security benefits. The site integrates third-party services such as Zoho Marketing Automation and InMobi's Consent Management Platform, reflecting a mature marketing and compliance infrastructure. Performance is moderate with good mobile optimization and SEO practices. Accessibility is basic and could be improved. The technical stack is well chosen for scalability and responsiveness, though some security best practices like DNSSEC and security headers are missing, representing areas for technical enhancement.
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.
