Cloud assessments require deep AWS/Azure/GCP expertise, IAM/identity testing competence, and familiarity with platform-specific misconfigurations including S3, IMDS, and serverless attack vectors. US buyers should look for FedRAMP 3PAO accreditation for federal cloud work, PCI QSA for payment-handling environments, and SOC 2 audits for SaaS clients.
