Your Strategy
Use guest accounts (Entra ID B2B) instead of local accounts. Enforce MFA for externals too and limit access to the absolute minimum (Least Privilege).Best Practices
- ▸Identity: Enforce phishing-resistant MFA (FIDO2) and use Conditional Access.
- ▸Data Flow: Block exfiltration via Tenant Restrictions and DLP policies.
- ▸Governance: Review monthly which partners still require active access and integrate logs into your SIEM.
