TaaS for Multi-Cloud Environments: Testing Across AWS, Azure, and GCP

TaaS for Multi-Cloud Environments: Testing Across AWS, Azure, and GCP

The Multi-Cloud Testing Challenge

Each cloud provider implements security differently. AWS IAM policies use JSON documents with complex evaluation logic. Azure RBAC operates through a role-assignment model with inheritance. GCP IAM uses a resource hierarchy with organisation, folder, and project-level bindings. A misconfiguration in any one of these can expose data across your entire environment—but the misconfiguration looks different in each provider.

Cross-Cloud Attack Paths

The most dangerous multi-cloud vulnerabilities aren't within a single provider—they're between providers. A compromised Azure AD credential that grants access to an AWS-hosted application. An overpermissive GCP service account that bridges to an Azure-hosted API. Testing these cross-cloud paths requires understanding how your providers interconnect.

Why Provider-Specific Expertise Matters

Generic network testers who treat cloud 'like any other infrastructure' miss IAM privilege escalation paths, cloud-specific service abuse scenarios, and cross-account attack chains. Penetrify's cloud-native testing assigns practitioners with deep AWS, Azure, and GCP expertise—testers who understand the nuances of each provider's security model and can test cross-cloud attack paths that bridge your environments.

Unified Reporting Across Clouds

Multi-cloud testing should produce a single, unified report—not separate documents per provider. Findings should be prioritised by actual risk, regardless of which cloud they originate from, and mapped to the compliance controls that apply across your entire infrastructure.

The Bottom Line

Multi-cloud environments multiply the complexity of cloud security testing. Penetrify provides unified testing across AWS, Azure, and GCP with practitioners who understand each provider's specific attack vectors and can map cross-cloud exploitation paths.

Frequently Asked Questions

Do I need separate pentests for each cloud provider?
No. A well-scoped TaaS engagement should cover all your cloud environments in a single engagement, testing within each provider and across providers for cross-cloud attack paths.
Which cloud is hardest to secure?
Each has its own challenges. AWS IAM is notoriously complex. Azure AD integration creates large attack surfaces. GCP's resource hierarchy requires careful policy management. The 'hardest' depends on your specific configuration, not the provider.
