Supply chain security risks are escalating as organizations become more dependent on interconnected vendors and third-party digital ecosystems. Supply Chain Cyber Attacks exploit weak links in suppliers, software providers, and service partners to infiltrate larger target organizations, often bypassing traditional security defenses and causing widespread operational and financial disruption.

Strengthening end-to-end visibility across the supply chain has become essential for preventing cascading security failures and ensuring business continuity in highly networked environments.
