- It clarifies exit plans and incident communication for critical services.
Who it applies to
- Companies dependent on cloud, SaaS, and outsourced services.
- Organizations sharing customer data with suppliers.
- Teams facing DORA, ISO 27001, SOC 2 readiness, or GDPR/KVKK expectations.
Why it matters
- Vendor incidents can directly affect customers and business continuity.
- Ongoing monitoring matters as much as pre-purchase review.
- Auditors and customers frequently ask for vendor evidence.
Practical roadmap
- Create vendor inventory with critical services and data access.
- Define review depth and approval flow by risk tier.
- Standardize security evidence, contract clauses, and storage location.
- Set annual review and incident notification routines for critical vendors.
- Document exit plans and alternative service scenarios.
Common mistakes
- Treating vendor risk as a procurement form only.
- Reviewing critical vendors with the same depth as low-risk tools.
- Separating contract, evidence, and operational ownership.
