Supply Chain Risk Management: Protecting Your Organization from Third-Party Breaches
Third-party relationships now touch every layer of your operations—from cloud and SaaS to logistics and outsourced IT. This ebook shows how vendor risks enter, spread, and can be contained with real-time visibility, segmentation, and accountable leadership—so a partner’s compromise doesn’t become your breach. (See the table of contents and chapter overviews on pp. 2, 4–16.)
