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

Adzuna Ltd operates a comprehensive job search engine primarily targeting the UK market but with international reach through multiple country-specific domains. The platform aggregates job listings from thousands of sources, providing users with a centralized search experience enhanced by additional services such as CV valuation and automated job applications. The website demonstrates a mature digital presence with a professional design, clear navigation, and mobile optimization. Technically, it leverages modern JavaScript libraries, CDN hosting, and integrates multiple analytics and advertising tools to support its business model. Security-wise, the site enforces HTTPS and employs secure form practices but lacks explicit security headers and a dedicated security policy page. Privacy compliance is well addressed with clear privacy and cookie policies, including GDPR considerations. Overall, the site is trustworthy and professionally maintained, with no signs of blocking or WAF interference.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 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';…

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

Adzuna holds a strong market position as a job search aggregator with a decade of experience and a broad international footprint. Its business model focuses on providing job seekers with comprehensive search capabilities and value-added services, likely monetized through advertising and recruitment partnerships. The company targets job seekers and recruiters, offering tools for both audiences. The presence of multiple country-specific domains indicates a strategic approach to localization and market penetration. The lack of direct contact information on the homepage suggests a focus on self-service and automated interactions. The company appears to maintain a consistent brand and leverages partnerships with major advertising and analytics providers to optimize reach and performance.

Security posture

The website exhibits a solid security foundation with HTTPS enforced and secure handling of user inputs in forms. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency in security governance. The extensive use of third-party tracking and advertising scripts increases the attack surface and privacy considerations but appears managed within compliance frameworks. Overall, the security posture is good but could be enhanced with additional headers and formal security disclosures.

Recommendations

  1. Implement and explicitly declare security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a dedicated security policy page detailing security practices and incident response procedures to improve transparency and trust.
  3. Add a security.txt file at the root domain to facilitate responsible vulnerability disclosure.
  4. Review and minimize third-party tracking scripts where possible to reduce privacy risks and improve performance.
  5. Consider providing clear company contact information for support and security inquiries to enhance user confidence.

Technical notes

Notes

The website is built on a modern technology stack including jQuery, Tailwind CSS, and Swiper.js for UI components, supported by CDN hosting via kxcdn.com for performance optimization. It integrates multiple analytics and advertising platforms such as Google Tag Manager, Facebook Pixel, Bing Ads, and Trackuity, indicating a mature marketing infrastructure. The site is mobile-optimized with responsive design and accessibility considerations. No CMS is explicitly detected, suggesting a custom or proprietary platform. Performance is fast, and SEO is well addressed through meta tags and structured navigation. Technical risks are minimal but include reliance on multiple third-party scripts which require ongoing monitoring for security and privacy compliance.
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.
