Risk levelMedium

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

Greystar Worldwide, LLC operates a professional real estate website focused on apartment rentals and property management services across multiple U.S. cities. The company positions itself as a large, enterprise-level real estate management firm offering a wide portfolio of residential communities. The website is well-structured, with clear navigation, comprehensive privacy and terms policies, and a strong brand presence supported by social media channels. Technically, the site uses modern frameworks such as Next.js and Sitecore CMS, ensuring good performance and mobile optimization. Security posture is strong with HTTPS and security headers implemented, though no explicit incident response or vulnerability disclosure information is provided. The absence of WHOIS data is a notable anomaly but does not detract from the overall legitimacy indicated by the website content and external references.

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

3 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 X-Frame-Options header

      Prevents clickjacking attacks

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

  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

Greystar is positioned as a leading real estate management company with a focus on residential rentals. Their business model centers on property management, leasing, development, and investment services. The target audience includes renters seeking apartments and investors interested in real estate assets. The company leverages a global platform and deep market knowledge to maintain a competitive advantage. The website supports business growth through location guides, renter resources, and a loyalty program. Partnerships and career opportunities are highlighted, indicating a mature organizational structure. The company maintains a consistent brand image and trust signals such as an Equal Housing Opportunity statement and comprehensive legal disclosures.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, presence of key security headers, and secure form handling. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of a public vulnerability disclosure policy or security.txt file and absence of incident response contact details represent gaps in transparency and readiness. Compliance with privacy regulations is supported by a comprehensive privacy policy and cookie consent mechanism. Overall, the security maturity is good but could be enhanced by adding explicit security governance documentation and incident response information.

Recommendations

  1. Publish a public vulnerability disclosure or security.txt page to improve transparency and encourage responsible reporting.
  2. Provide clear incident response contact information, such as a dedicated security email address.
  3. Regularly audit and update third-party scripts and CMS components to mitigate potential vulnerabilities.
  4. Enhance privacy compliance disclosures with explicit data retention policies and user rights information.
  5. Maintain continuous monitoring and penetration testing to uphold security posture and trust.

Technical notes

Notes

The website is built on a modern technology stack including React and Next.js frameworks, integrated with Sitecore CMS for content management. The use of preloading images and deferred scripts indicates performance optimization efforts. The site is mobile responsive and accessible, with semantic HTML and ARIA attributes. SEO is well addressed with meta tags and structured navigation. No hosting provider details were explicitly found, but the presence of Sitecore and Next.js suggests a cloud-based or managed hosting environment. Performance is moderate, with room for improvement in image optimization and script loading strategies. Technical risks are minimal but should be managed through regular updates and security reviews.
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.
