The Supply Chain Threat
Attackers target your vendors because it's easier than attacking you directly. One compromised supplier can expose thousands of downstream customers.
Critical Insight
62% of breaches involve third parties. Supply chain attacks cost 12% more and take 103 days longer to detect than direct attacks.
