Is zillowgroup.com a Scam? Security Check Results - Zillow Group

zillowgroup.com Security Report Summary

zillowgroup.com received a security score of 69 out of 100 in Guard's comprehensive security analysis, classified as "Moderate Risk". This report covers Zillow Group's website security posture. Zillow Group operates in the real estate industry in United States.

The website demonstrates a moderate overall security posture with no critical issues found, but several high and medium severity gaps that pose significant risks. Key vulnerabilities include missing essential security headers, lack of GDPR compliance measures such as cookie policy and consent mechanisms, and absence of comprehensive security governance aligned with NIS2 requirements. While network security and email security are strong, deficiencies in incident response, security policy documentation, and vulnerability disclosure processes expose the business to operational and regulatory risks. The presence of mixed content and weak HSTS configurations could lead to data interception and man-in-the-middle attacks. Non-compliance with GDPR and NIS2 frameworks may result in regulatory penalties and damage to brand reputation. Immediate remediation will reduce exposure to cyber threats and enhance customer trust. Overall, addressing these gaps is critical to aligning security practices with business continuity and regulatory expectations.

The security scan identified 25 findings across security headers, SSL/TLS, DNS health, email security, GDPR compliance, and NIS2 compliance analysis modules.

Technologies detected: WordPress, jQuery, Bootstrap 4, Google Analytics (gtag.js), Google Tag Manager, Site Kit by Google, Google Analytics, Istio Envoy.

Technical Analysis

Comprehensive security assessment findings

Additional Findings

Critical technical findings include missing X-Frame-Options and Content-Security-Policy headers, which expose the site to clickjacking and cross-site scripting attacks. The absence of a cookie policy and consent banner violates GDPR requirements, risking regulatory penalties. Lack of documented security policies, incident response procedures, and security contact points contravenes NIS2 mandates, impairing effective security management and incident handling. Mixed content issues undermine HTTPS protections, potentially exposing data to interception. Weak HSTS settings with a short max-age reduce the enforcement of secure connections. DNS security is weakened by the absence of DNSSEC, increasing vulnerability to DNS spoofing. Together, these issues elevate the risk of exploitation, regulatory non-compliance, and reputational damage.
