How do Third Party Supplier Security Policies Protect Your Business?

An excellent third-party supplier security policy can help to protect your business from threatening risks. Policies can also help you find compliant suppliers and even mitigate the risks associated with working with a non-compliant provider.

Third-party supplier security policies typically fall into one of two categories: risk management and compliance guidance.

Risk management policies identify the risks associated with working with a particular supplier and outline measures businesses can take to mitigate those risks.

Compliance guidance, on the other hand, provides detailed instructions on how to comply with specific regulations and standards.

Both types of policies can be tailored to meet the specific needs of your business. For example, a risk management policy may recommend screening suppliers for prior criminal history, while a compliance policy may provide detailed instructions on adequately documenting and tracking supplies.
