Hardware Supply Chain Hardening & Attack Surface Reduction
Eliminated supply chain and hardware-level attack vectors by enforcing strict procurement, inspection, and physical hardening controls across all deployed systems.
Situation
The client required assurance that no hardware components introduced risk from compromised manufacturing sources or embedded communication capabilities. Traditional enterprise hardware configurations were insufficient for this threat model.
Solution
A controlled hardware supply chain and physical hardening program was implemented.
OUTCOMES
Challenges
Supply
- •Untrusted manufacturing sources
- •Hardware provenance uncertainty
