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

Manpower UK operates as part of the global ManpowerGroup, a leading workforce solutions company with over 75 years of experience. The website serves job seekers and employers in the UK, offering staffing, recruitment, and career development services across sectors such as transport, logistics, engineering, and customer service. The company positions itself as a trusted partner with a large talent pool and a network of local branches. Technically, the site is built on modern frameworks including React and Sitecore CMS, with integrations for analytics and authentication via Microsoft Azure B2C. The site demonstrates strong mobile optimization, accessibility, and SEO practices. Security posture is robust with HTTPS, security headers, and secure form handling, though no explicit public security policy or incident response contacts are published. Overall, the site reflects a mature enterprise digital presence with good privacy compliance and trust indicators. The absence of WHOIS data for the exact domain is due to Nominet UK domain naming rules, but the site content and external references confirm legitimacy.

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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  2. 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 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';…

  3. 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

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

Manpower UK is a key player in the UK staffing and recruitment market, leveraging the global ManpowerGroup brand. Its business model focuses on flexible staffing solutions, direct hire, and workforce management, supported by training and development programs. The company targets a broad audience including job seekers and employers across multiple industries. The website's content and structure emphasize diversity, equity, and inclusion initiatives, reflecting current market trends and corporate responsibility. The presence of multiple subsidiary brands and a comprehensive branch locator indicates a wide operational footprint. The company maintains a strong partnership ecosystem and digital marketing presence, enhancing its competitive advantage.

Security posture

The website exhibits a strong security posture with enforced HTTPS, modern security headers, and secure authentication mechanisms via Azure B2C. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a public vulnerability disclosure policy or security.txt file and lack of incident response contact details represent areas for improvement. Privacy policies and cookie consent mechanisms are well implemented, supporting GDPR compliance. The use of third-party scripts like Google Tag Manager and HubSpot forms is managed with appropriate event tracking. Overall, the security maturity is high but could benefit from enhanced transparency and incident readiness.

Recommendations

  1. Publish a dedicated vulnerability disclosure or security.txt page to encourage responsible reporting.
  2. Provide clear incident response contact information to improve security communication.
  3. Include references to security frameworks or certifications to enhance trust.
  4. Regularly review and audit third-party scripts and dependencies for vulnerabilities.
  5. Enhance user education on privacy and security through visible notices or FAQs.

Technical notes

The website is built using React and Sitecore CMS, indicating a modern and scalable architecture. Integration with Google Tag Manager and Google Maps API supports analytics and location-based services. Authentication is handled via Microsoft Azure B2C, providing secure user management.

The use of canonical and Open Graph meta tags supports SEO and social media sharing. No critical technical debt or deprecated technologies were identified, suggesting good maintenance and modernization practices.
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.
