Without Premium Support, critical incidents face slower response, reducing availability and delaying containment of security events. Limited Trusted Advisor coverage lets misconfigurations persist, risking data exposure and privilege misuse. Lack of expert guidance increases change risk during production impacts.

Adopt Business or higher for production and mission-critical accounts.

• Integrate Support into IR with defined contacts/severity
• Enforce least privilege for case access
• Use Trusted Advisor for proactive hardening
• If opting out, ensure an equivalent 24/7 support and escalation path
