Risk levelMedium

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

The website segmentationportal.com is a business-focused platform operated under the Experian brand, offering advanced consumer segmentation and financial behavior analytics primarily targeting marketing professionals and organizations in the UK. It provides detailed insights into consumer demographics and financial profiles to enable targeted marketing and customer engagement. The site integrates multiple trusted technologies including jQuery, Bootstrap, Google Analytics, and Adform tracking, reflecting a moderate level of digital maturity. The presence of cookie consent mechanisms and privacy policies linked to official Experian domains indicates good privacy compliance. Security posture is moderate; while HTTPS is implied and error logging is implemented, some security best practices such as proper password input types and security headers are lacking. The absence of WHOIS registration data for the domain raises concerns about domain legitimacy, although the website content and branding strongly align with Experian's official services. Overall, the site is professional and trustworthy but would benefit from enhanced security measures and domain registration transparency.

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

2 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. 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

Experian holds a strong market position as a leader in consumer intelligence and segmentation with over 30 years of experience. The business model is B2B, providing data analytics and marketing services to organizations seeking to improve customer engagement through segmentation. Key services include consumer segmentation, financial behavior analysis, and cross-channel marketing platforms. The target audience includes marketing professionals and enterprises in the finance sector within the UK. The website reflects a large enterprise scale with consistent branding and professional content. Partnerships with domains like rightmove.co.uk and qas.co.uk indicate a broad ecosystem. The lack of explicit company founding date and some missing WHOIS data suggest areas for improved transparency.

Security posture

The security maturity level is moderate. The site uses HTTPS and includes cookie consent with opt-out for Google Analytics, demonstrating privacy awareness. However, the login form's password field initially uses a text input type, exposing user input, which is a security risk. No explicit security headers such as CSP or HSTS were detected, and there is no visible security policy or incident response contact information. The site lacks a vulnerability disclosure or security.txt file. These gaps could expose the site to common web vulnerabilities and reduce user trust. The absence of WHOIS registration data also impacts domain trustworthiness. Overall, the security posture requires improvements in input handling, header implementation, and transparency to meet higher compliance standards.

Recommendations

  1. Change the login form password field to use input type 'password' to protect user credentials.
  2. Implement and verify security headers including Content Security Policy (CSP), HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Obtain and display valid WHOIS registration data to improve domain legitimacy and trust.
  5. Enhance mobile optimization and accessibility features to improve user experience and compliance.

Technical notes

Notes

The website employs a standard modern tech stack with jQuery, jQuery UI, Bootstrap, and Google Analytics. It uses asynchronous script loading and AJAX for error logging, indicating a dynamic and interactive design. Performance is moderate with some room for improvement in mobile responsiveness and accessibility. The site lacks a detected CMS, suggesting a custom or proprietary platform. External dependencies include trusted domains such as Twitter and Adform for social and advertising functionalities. The site uses cookie consent banners and local storage for user preferences. Technical debt is minimal but security-related technical improvements are needed to reduce risk.
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.
