FAQ
Is costco.com safe?
Based on current analysis, costco.com leans generally safe with a 95/100 trust score. Key trust factors include 29.4-year domain history, public traffic rank, and business infrastructure; mixed review signals should still be checked.
What supports the trust score for costco.com?
Key factors include registrar information (CSC Corporate Domains, Inc.), hosting in US, a domain age of 29.4 years, and presence in public traffic rankings. Major malware and phishing engines did not report active blacklist detections at the time of review, but reputation-related warning signals were still present. The trust score blends security detections, domain and infrastructure signals, on-page behavior patterns, and public review history when available. The overall assessment remains mixed because third-party reputation sources do not point to a fully consistent trust profile.
Is costco.com reliable for online purchases?
Current analysis does not show major malware or phishing threats. Buyers should still review return policies, delivery terms, and recent independent customer feedback before paying.
