Vendor / Third-party Exceptions: Managing Risks from External Partners
SMEs increasingly rely on third-party vendors cloud services, payment processors, contractors, and software providers. Each of these relationships can introduce exceptions, especially when vendor practices don't align with internal policies.
Common Third-Party Exceptions
- Vendors using weaker authentication methods.
- Outsourced IT providers needing admin access.
- Cloud services not meeting all regulatory requirements.
- Contractors using personal devices for work.
Risks of Ignoring Vendor Exceptions
Third-party exceptions expand the attack surface.
If not managed, they create risks SMEs cannot directly control. Regulatory frameworks such as GDPR and PCI DSS also hold organizations accountable for vendor-related risks.
Managing Vendor Exceptions
1. Vendor Risk Assessments
Before approval, assess vendor security controls. Document any gaps as exceptions.
2. Contractual Controls
Include clauses requiring vendors to remediate exceptions within defined timelines.
3. Monitoring and Reviews
Track vendor exceptions as part of your regular exception register.
4. Exit Plans
If a vendor consistently requires high-risk exceptions, consider alternatives.
Practical SME Approach
Simple Solutions for Limited Resources
Even with limited resources, SMEs can use simple checklists or shared registers to track vendor exceptions. The key is ensuring exceptions are not forgotten once contracts are signed.
Strategic Benefit
By managing third-party exceptions, SMEs demonstrate maturity to clients, regulators, and insurers. This builds trust while ensuring that external partnerships don't become weak links in security.
