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

Glassdoor is a prominent technology company offering an online platform for job seekers and employers, focusing on job listings, company reviews, and salary information. The website analyzed is the German localized domain (glassdoor.de), currently presenting a Cloudflare security challenge page that blocks direct content access. This indicates the use of advanced security measures to protect against bots and malicious traffic. The technical infrastructure leverages Cloudflare services including Turnstile CAPTCHA and Google Analytics for traffic analysis. However, the current page lacks visible privacy, cookie, or terms of service policies, and no contact or security incident response information is provided on this challenge page. The security posture is difficult to fully assess due to content blocking, but the use of Cloudflare suggests a baseline of security best practices. Overall, the site is legitimate and consistent with the Glassdoor brand but limited in accessible content for full analysis.

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

8 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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';…

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

Glassdoor operates as a large technology company in the online job and recruitment sector, targeting job seekers, employers, and HR professionals. Its business model revolves around providing job listings, company reviews, and salary data, monetized through advertising and recruitment services. The German localized domain aligns with its international market presence. The company benefits from a strong brand and market position but the analyzed page does not reveal detailed business or contact information. The use of Cloudflare and Google Analytics indicates a mature digital ecosystem, though transparency on privacy and security policies is lacking on this page.

Security posture

The website is protected by Cloudflare's security mechanisms, including a Turnstile CAPTCHA challenge to verify human users, which is a strong defense against automated attacks. However, the absence of visible security headers, privacy policies, or incident response contacts on the challenge page limits the assessment of compliance and security maturity. No vulnerabilities or exposed sensitive data were detected in the accessible content. The security score is limited by the inability to access full site content. The domain registration uses Cloudflare nameservers and privacy protection, which is standard for large enterprises and does not raise suspicion. Overall, the security posture is adequate but could be improved by making security and privacy policies more accessible.

Recommendations

  1. Make privacy, cookie, and terms of service policies clearly accessible on the website to improve transparency and compliance.
  2. Publish contact information and dedicated security incident response channels to enhance trust and incident handling.
  3. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Ensure SSL/TLS configurations are strong and regularly audited to maintain excellent encryption standards.
  5. Consider providing a security.txt file or vulnerability disclosure policy to encourage responsible reporting.

  4. The page is minimal and serves as a bot verification gate.
  5. Use of Google Analytics and Cloudflare Insights for tracking is detected.

Technical notes

Notes

The website uses Cloudflare as a hosting and security provider, leveraging its DNS and WAF capabilities. Google Analytics and Cloudflare Insights are used for traffic monitoring and analytics. The presence of Cloudflare Turnstile CAPTCHA indicates modern bot mitigation technology. The HTML content is minimal due to the security challenge, limiting SEO and accessibility features. No CMS or specific web frameworks are detectable from the provided content. Performance is moderate, constrained by the challenge page. Mobile optimization and accessibility are basic, as the page is primarily a verification gate rather than full content. Technical modernization opportunities include enhancing visible metadata, structured data, and user experience post-challenge.
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.
