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.

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

LinkedIn holds a dominant market position in the professional social networking sector, targeting professionals, job seekers, and learners globally. Its business model revolves around connecting professionals, offering recruitment solutions, and providing educational content. The platform's extensive reach and service diversity indicate strong revenue streams from advertising, premium subscriptions, and talent solutions. The ecosystem includes numerous localized domains catering to various countries and languages, enhancing global accessibility. Strategic partnerships and integrations with major technology providers support its operational scale. The absence of direct contact information on the homepage aligns with its enterprise nature, focusing on digital engagement rather than direct customer support via phone or email.

Security posture

The website exhibits a mature security posture with enforced HTTPS, secure form handling including CSRF tokens, and a visible cookie consent mechanism indicating GDPR compliance. Use of third-party scripts like Google Identity Services and Tealium is managed with asynchronous loading to minimize risk. However, the lack of publicly available security policies, incident response contacts, and vulnerability disclosure programs suggests areas for improvement in transparency and readiness communication. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The security score is high but could be enhanced by publishing explicit security governance documents and providing clear channels for security incident reporting.

Recommendations

  1. Publish a dedicated security policy page detailing security governance and controls.
  2. Establish and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear contact information for security incidents and abuse reporting.
  4. Regularly audit and update third-party scripts to mitigate supply chain risks.
  5. Enhance transparency around data retention and privacy practices to strengthen user trust.

Technical notes

Notes

LinkedIn's technical infrastructure is built on modern web standards with extensive use of JavaScript, SVG graphics, and asynchronous script loading for performance optimization. The presence of Google Identity Services facilitates secure OAuth-based authentication. Tag management via Tealium indicates advanced analytics and marketing integration. The website is mobile-optimized with responsive design and accessibility features such as skip links and ARIA roles. Performance appears fast with lazy loading of images and scripts. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed but the site is served over HTTPS with strong security headers implied. Overall, the technical setup supports a scalable, secure, and user-friendly platform.
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.
