Cloud Application Testing Services

What is cloud application testing?

Most organisations now rely on cloud services in some form, whether through public cloud platforms, SaaS applications, identity providers, APIs, storage services, serverless functions, containers or infrastructure-as-code deployments. This creates a complex attack surface where misconfigurations, excessive permissions and weak identity controls can expose sensitive systems and data.

Cloud application testing is the security assessment of applications, services and infrastructure that run in or integrate with cloud environments.

It goes beyond traditional application testing by assessing the cloud services, permissions, identities, storage, APIs, networking and deployment pipelines that support the application.

A cloud application may rely on managed databases, object storage, serverless functions, containers, Kubernetes, API gateways, queues, secrets management, identity providers, CI/CD pipelines and infrastructure-as-code templates. Weaknesses in any of these areas can create exposure.

Cloud application testing helps identify whether cloud-hosted applications are securely designed, configured, deployed and operated. It also helps determine whether an attacker could exploit misconfigurations, excessive privileges or weak integration points to access sensitive data or compromise the wider environment.

When you need cloud application testing services

Cloud application testing is valuable whenever your organisation hosts applications, data or business-critical services in the cloud.

You may need cloud application testing before launching a new cloud-hosted application, after migrating workloads to Azure, AWS or Google Cloud, following changes to identity and access management, or when introducing new APIs, storage services, serverless components or container platforms.

Testing is also important after infrastructure-as-code changes, CI/CD pipeline updates, cloud network redesigns, supplier integrations or the deployment of new SaaS or identity platforms.

For regulated organisations, cloud application testing can support audit, compliance and risk management by providing evidence that cloud controls, access permissions and application security risks have been assessed.

Common cloud infrastructure security risks

Cloud environments introduce different security risks from traditional infrastructure.

Common issues include overly permissive identity and access management, exposed storage buckets, public-facing services, weak API authorisation, insecure secrets handling, insufficient logging, insecure security groups, misconfigured firewalls, unencrypted data stores and poorly restricted management interfaces.

Hybrid environments can add further complexity. Cloud platforms often connect to on-premise networks, corporate identity systems, SaaS platforms and third-party suppliers. A weakness in one area can create an attack path into another.

Identity platforms are particularly important. Services such as Microsoft Entra ID, AWS IAM, single sign-on and privileged access management often provide authorisation across the organisation. Weak configuration, excessive permissions, poor conditional access, insecure application registrations or unmanaged service principals can create significant risk.

Infrastructure-as-code can also introduce security weaknesses at scale. Misconfigured templates, permissive policies, insecure defaults or exposed secrets can repeatedly deploy the same vulnerability across multiple environments.

Cloud application testing helps identify these risks before they are exploited.

Our cloud application testing methodology

Cyndicate Labs tailors each cloud application test to your platform, architecture and risk profile.

We begin by understanding the application, cloud provider, identity model, data flows, user roles, APIs, integrations, deployment processes and supporting services. This helps us define a scope that reflects how the environment actually works.

Testing may include application assessment, API testing, cloud configuration review, identity and access testing, storage review, network control validation, secrets management review, logging and monitoring assessment, serverless testing, container review and infrastructure-as-code analysis.

For infrastructure-as-code reviews, we assess templates and configuration files for insecure defaults, excessive permissions, exposed secrets, weak network rules, missing encryption and other risks that could be deployed into live environments.

Our approach combines manual expertise with appropriate tooling and cloud-native analysis. We focus on exploitable weaknesses, attack paths and practical remediation rather than long lists of low-context configuration issues.

Testing across cloud providers

Cyndicate Labs provides cloud application testing across the major public cloud platforms, including Microsoft Azure, Amazon Web Services and Google Cloud Platform.

In Microsoft Azure, testing may include Azure subscriptions, resource groups, storage accounts, App Services, Azure Functions, Microsoft Entra ID, managed identities, role assignments, conditional access, application registrations and hybrid identity integrations.

In AWS, testing may include IAM policies, roles, S3 buckets, EC2, Lambda, API Gateway, security groups, CloudTrail, Secrets Manager, EKS, ECS and cloud network configuration.

In Google Cloud Platform, testing may include IAM roles, service accounts, Cloud Storage, Cloud Functions, Cloud Run, GKE, VPC configuration, logging, secrets and organisation policy controls.

Many organisations operate across more than one provider. We can assess multi-cloud and hybrid environments, helping you understand where identity, networking, APIs, data flows and operational controls create risk across platforms.
