Selecting evidence-heavy delivery without a remediation execution workflow
Deloitte and EY deliver evidence workflows and operating procedures, but buyers should also require a remediation execution path, such as the managed control mapping and remediation translation described by KPMG or Infosys.
Underestimating multi-account rollout governance coordination requirements
Accenture warns that program delivery needs enterprise coordination to keep rollout governance on track, so governance decision cadence and stakeholder roles must be defined before implementation starts.
Assuming orchestration depth is built in when the provider is primarily assurance-focused
PwC frames automation and API-driven integration depth as dependent on the customer security toolchain, so buyers should validate which integrations are delivered versus left to customer tooling.
Ignoring identity mapping needs for finding-to-remediation traceability
IBM and Tata Consultancy Services both connect findings to identity context or tie audit logging into policy-to-remediation workflows, so buyers should confirm the identity mapping and audit-history traceability needed for governance.
Choosing a partner that cannot support SIEM and incident workflow wiring
Wipro emphasizes SIEM-based visibility and managed incident handling, so security operations buyers should verify that incident workflows receive cloud-control context rather than only alerting.
