What is Supply Chain Security? An explanation of implementation design and SCS evaluation systems to prevent procurement disruption risks.

"We've taken measures to prevent this, so why is procurement stopping?"

Much of the reason lies in "structural risks across the entire supply chain" that cannot be prevented by individual companies alone.

In fact, cases where intrusions via subcontractors or damage to supplier companies escalate, ultimately leading to production stoppages or Service disruptions, are already occurring in large corporations.

• Even if your company has robust security measures in place, intrusions can still occur through business partners.
• Due to damage to suppliers, deliveries have stopped, and business operations have been halted.
• Our company's customer information was leaked due to an accident at our outsourced company.

These risks are no longer just an IT department issue; they are Issue that directly impact procurement, sustainability, and management decision-making.

▼Do you have any of these Issue?

• We are unaware of the security status of our suppliers.
• Third-party risk management is becoming dependent on individual expertise.
• I don't know how to deal with the SCS evaluation system.
• The IT department is left to handle everything, and the procurement department is not involved.
• I'm struggling with how to incorporate security requirements into the contract.

→If even one of these applies to you, this document will help you organize your company's Issue and prioritize how to address them.
