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

Greenhouse Software, Inc. operates a leading AI-powered applicant tracking system and hiring platform designed to streamline the recruitment lifecycle from sourcing to onboarding. The company targets businesses ranging from early-stage startups to modern enterprises, offering scalable workflows, AI recruiting tools, and comprehensive talent management solutions. Their market position is strong, supported by enterprise adoption and industry awards such as Best Software for Enterprise in 2024. Technically, the website is built on modern web technologies including Webflow CMS, Google Tag Manager, Marketo forms, and OneTrust for cookie consent, ensuring a fast, mobile-optimized, and accessible user experience. The site employs advanced animations and interactive navigation, reflecting a mature digital infrastructure. From a security perspective, the site enforces HTTPS, implements key security headers, and uses secure form handling via Marketo. Privacy compliance is robust with clear privacy and cookie policies aligned with GDPR. However, the absence of explicit security policies, incident response details, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. Overall, the website presents a professional, trustworthy, and business-focused digital presence with high content quality and technical maturity. The missing WHOIS data is a notable anomaly that slightly reduces domain trustworthiness but does not detract from the evident legitimacy and enterprise-grade positioning of the company.

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

6 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  2. GDPR outside view

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

    • 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

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

Greenhouse is positioned as a SaaS provider in the HR technology sector, focusing on applicant tracking and AI-driven recruiting solutions. Their business model relies on subscription services targeting a broad range of business sizes, emphasizing scalability and integration capabilities. The company maintains a strong partnership ecosystem, including event sponsorships and integration platforms, enhancing market reach and customer engagement. Growth indicators include comprehensive resource offerings, community engagement, and a multi-language website catering to international audiences. Competitive advantages include AI-powered tools, a comprehensive platform covering the entire hiring process, and recognition through industry awards. Revenue streams are primarily from software subscriptions and enterprise contracts. The company’s strategic focus on people-first culture and modern enterprise needs aligns with current market trends in talent acquisition and management.

Security posture

The website demonstrates a solid security posture with HTTPS enforcement, modern security headers, and secure form integrations. Privacy compliance is evident through detailed policies and cookie consent mechanisms. However, the lack of a published security policy, incident response contacts, and vulnerability disclosure program suggests gaps in security transparency and incident readiness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The use of third-party marketing and analytics tools is managed with consent mechanisms, reducing privacy risks. Business impact of current gaps is moderate, primarily affecting trust and compliance perception rather than direct technical risk. Enhancing security documentation and providing clear incident response channels would strengthen the overall security culture and stakeholder confidence.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance frameworks.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide direct security contact emails (e.g., security@greenhouse.com) for incident reporting and inquiries.
  4. Regularly audit and update third-party scripts and marketing tools to mitigate potential vulnerabilities.
  5. Enhance accessibility features to meet or exceed WCAG 2.1 AA standards for broader inclusivity.

Integration with marketing automation tools like Marketo and Intellimize supports advanced user engagement and conversion tracking. Hosting via Webflow ensures reliable performance and scalability.

Overall, the technical infrastructure supports the business goals effectively with room for incremental improvements.
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.
