What is Cloud Security Assessment?

Cloud Security Assessment is a systematic evaluation of your cloud infrastructure, configurations, access controls, data protection mechanisms, and security posture across all cloud service layers—Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Unlike traditional infrastructure assessments, cloud security requires specialized expertise in cloud-native services, identity and access management, serverless architectures, container orchestration, and the unique security challenges introduced by dynamic, elastic, and multi-tenant environments.

GrayXploit conducts thorough cloud security assessments that examine compute resources, storage services, networking configurations, identity management, encryption implementations, logging and monitoring, compliance controls, and third-party integrations. Our methodology combines automated security scanning, manual configuration review, penetration testing, and architectural analysis to provide a comprehensive view of your cloud security posture.
