Verdict: LinkedIn has Microsoft-grade security infrastructure but its professional data is extensively scraped and used for phishing. The platform itself collects significant data for its advertising and recruitment businesses.
LinkedIn is the world's largest professional networking platform with over 900 million members. Owned by Microsoft, it holds sensitive career and employment data that makes it a high-value target for scrapers and social engineers.
