Risk levelLow

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

Optum UK operates as a healthcare solutions and services provider focused on improving the UK health and care system through actionable insights and technology. The website presents a professional and consistent brand aligned with Optum Inc., a recognized enterprise in healthcare technology and services. The site highlights key services such as Population Health Management and Medicines Optimisation, targeting NHS and related stakeholders. Technically, the site is built on Adobe Experience Manager with modern marketing and analytics tools, delivering a good user experience with mobile optimization and accessibility considerations. Security posture is solid with HTTPS and consent management, though explicit security headers and published security policies are absent. WHOIS data is unavailable due to domain registration issues, which slightly impacts trust but does not detract from the site's legitimacy based on content and branding.

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

3 findings rated critical or high. Fix these first.

  1. 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

  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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 14 days

      What to do: Renew domain registration before expiration

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 positions itself as an established healthcare technology provider with operational experience in the NHS and international markets. Its business model revolves around delivering data-driven healthcare solutions and services. The website's content and navigation reflect a mature enterprise with consistent branding and trust signals such as privacy and cookie policies. The partnership with EMIS Health is indicated, suggesting a broader ecosystem. The absence of phone contact details may indicate a preference for digital communication channels. The use of Adobe Experience Manager and integrated marketing tools suggests a well-resourced digital infrastructure supporting business growth and customer engagement.

Security posture

The website enforces HTTPS and employs privacy-conscious analytics with PII masking and consent management via TrustArc. However, the lack of explicit security headers such as Content Security Policy and HSTS is a gap. No vulnerabilities or exposed sensitive data were detected in the content. The absence of a published security policy or incident response contact reduces transparency. No vulnerability disclosure program or security.txt file was found. Overall, the security posture is good but could be improved by publishing security governance information and enhancing HTTP security headers.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add HTTP security headers including Content Security Policy, HSTS, and X-Frame-Options to enhance protection.
  3. Establish a vulnerability disclosure program and publish a security.txt file to encourage responsible reporting.
  4. Provide clear Data Protection Officer contact information to improve GDPR transparency.
  5. Regularly audit and update third-party scripts and marketing tools to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses Adobe Experience Manager CMS, leveraging modern JavaScript libraries such as jQuery 3.6.0 and Adobe Launch for tag management. It integrates marketing and analytics tools including Marketo Munchkin and Adobe Target, with TrustArc managing cookie consent. The site is mobile optimized and accessible with good SEO practices. Performance is moderate, with asynchronous loading of scripts and preloading of fonts. The WHOIS failure indicates the domain www.optum.co.uk is not a registered domain but likely a subdomain or alias, which is a technical anomaly but does not affect site functionality. Hosting provider details are not explicitly found. Overall, the technical infrastructure is modern and supports enterprise-level digital marketing and content delivery.
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.
