2. Cybersecurity posture
3. Financial health
4. Reputational risk
5. Operational capabilities

When selecting due diligence software for third-party risk management, it is essential to choose a tool that is scalable and capable of handling recurring tasks such as preparing, sending and reviewing due diligence assessments efficiently.
