Cloud technology now supports many of the systems businesses rely on every day. Companies use cloud platforms to store data, run applications, manage employees, support customers and connect teams across different locations. As cloud adoption grows, the security responsibilities of businesses also increase. A cloud provider may secure its infrastructure, but the customer still controls many important areas, including user access, application settings, stored data, network rules and third-party integrations.
A single mistake can create serious exposure. A company may leave a storage bucket open to the public, grant unnecessary administrator permissions or allow an external application to access sensitive information. A cloud security assessment helps identify these risks across AWS, Microsoft Azure, Google Cloud Platform and SaaS applications. It combines configuration review, vulnerability assessment and controlled penetration testing to determine whether an attacker could exploit weaknesses in the cloud environment.
Cloud VAPT applies the principles of vulnerability assessment and penetration testing to cloud accounts, workloads, applications, identities and online services.
What Is a Cloud Security Assessment?
A cloud security assessment reviews the systems, data and security controls that an organization manages in the cloud.
Security testers examine cloud accounts, applications, storage services, databases, identities and network configurations. They determine whether an attacker could exploit a weakness to access sensitive information, increase privileges or move between connected resources.
A standard vulnerability scan usually searches for known software flaws. Cloud VAPT goes further by checking cloud-specific risks such as exposed access keys, excessive permissions, public resources and insecure trust relationships.
For example, a company may fully patch a cloud database but still expose it to the internet. A user account may have no technical vulnerability but still hold enough privileges to access confidential information.
A professional cloud security assessment identifies both technical vulnerabilities and configuration weaknesses.
Why Do Cloud Environments Need Specialized Testing?
Cloud environments change quickly. Developers can create servers, databases, storage services and application components within minutes. Employees can also connect external tools to company data without always involving the security team.
This flexibility helps businesses grow, but it also increases the risk of security mistakes.
Cloud providers secure the physical infrastructure and the core services they operate. Customers must secure the resources, applications, identities and data they control.
The AWS Shared Responsibility Model provides a clear example of how a cloud provider divides security responsibilities with its customers.
A cloud provider cannot prevent a customer from assigning unnecessary permissions, using weak authentication or exposing a resource through an incorrect setting. Cloud VAPT focuses on these customer-controlled risks.
What Does Cloud VAPT Cover?
The scope of a cloud security assessment should reflect how the business uses cloud technology.
The testing team may examine cloud accounts, virtual machines, databases, storage services, containers, APIs, serverless functions and cloud-hosted applications. The assessment may also include identity platforms, backups, development environments and connections between cloud and internal networks.
Businesses should first identify which digital assets require security testing. This step helps the provider include the correct accounts, regions, applications and environments.
Testers usually focus on four main areas:
- Identity and access permissions
- Network exposure and segmentation
- Data storage and encryption
- Applications, APIs and cloud workloads
Cloud VAPT combines configuration analysis with controlled penetration testing. Configuration analysis identifies weak settings, while penetration testing shows whether an attacker could exploit them. This reflects the broader difference between identifying vulnerabilities and proving their impact.
Cloud Security Assessment Across Major Platforms
Each cloud platform uses different services, terminology and identity controls. Security testers must adapt their methods to the environment they assess.
| Platform | Main assessment areas | Common security risks |
| AWS | IAM, EC2, S3, RDS, Lambda, VPCs and security groups | Public storage, excessive IAM permissions and exposed access keys |
| Microsoft Azure | Entra ID, virtual machines, Azure SQL, Key Vault and storage accounts | Risky administrator roles, weak Conditional Access and public services |
| Google Cloud | Cloud IAM, service accounts, Compute Engine, Cloud Storage and GKE | Overprivileged service accounts, public resources and inherited access |
| SaaS platforms | Tenant settings, user access, sharing controls and third-party integrations | Dormant accounts, public links and excessive application permissions |
AWS Security Assessment
An AWS security assessment reviews the parts of Amazon Web Services that the customer controls.
Testers closely examine AWS Identity and Access Management. They review users, roles, policies, access keys and cross-account permissions to identify excessive access or possible privilege escalation.
They may also assess EC2 instances, S3 buckets, RDS databases, Lambda functions, VPCs and security groups.
Common findings include public storage, unrestricted administrative ports, missing multifactor authentication and IAM roles with unnecessary privileges.
The assessment focuses on the organization’s AWS resources, not Amazon’s underlying infrastructure.
Microsoft Azure Security Assessment
An Azure security assessment examines Azure subscriptions, Microsoft Entra ID, virtual networks, databases, applications and storage accounts.
Identity security plays a major role because Microsoft Entra ID may control access to both Azure services and Microsoft 365.
Testers look for unnecessary administrator roles, inactive users, weak Conditional Access policies and insecure application registrations. They may also review virtual machines, Azure SQL, Key Vault, public IP addresses and security-monitoring controls.
Google Cloud Security Assessment
A Google Cloud security assessment reviews GCP organizations, projects, identities, workloads and network controls.
Testers pay close attention to Cloud IAM and service accounts. Applications and automated processes often use service accounts to access cloud resources. An attacker may exploit an exposed key or overprivileged role to reach sensitive systems.
The assessment may cover Compute Engine, Cloud Storage, Cloud SQL, Google Kubernetes Engine, firewall rules and audit logging.
SaaS Security Assessment
A SaaS security assessment focuses on the organization’s own users, tenant settings, integrations and data.
Platforms such as Microsoft 365, Google Workspace, Salesforce, Slack and Atlassian may store sensitive business information even though an external provider manages the underlying software.
Testers review administrator accounts, multifactor authentication, guest users, sharing policies and connected applications.
They may discover that a former employee still has access, a user has shared confidential documents through a public link or a third-party application can read company files and emails.
How Does a Cloud Security Assessment Work?
The assessment begins with scoping. The organisation and the testing provider identify which cloud accounts, applications, environments and SaaS tenants the team can assess.
A clear scope keeps the testing authorised and helps the team avoid missing important resources. This becomes especially important when a company uses several providers, regions or development environments.
A properly defined VAPT scope should explain what the assessment includes, what it excludes and which testing methods the organisation permits.
The testing team then reviews the cloud architecture, asset inventory, identities and network connections. Automated tools help identify exposed services, known vulnerabilities and insecure settings.
Security specialists manually validate these findings because scanners may produce false positives or miss relationships between users, roles and connected services.
Where the scope allows it, testers safely verify whether an attacker could exploit a weakness. They may test whether a low-privileged account can access restricted data, assume a more powerful role or reach another workload.
The team follows the same general process used during a professional VAPT assessment, but it adapts the tools and methods to cloud environments.
At the end of the engagement, the provider documents the evidence, business risks and recommended fixes in an actionable VAPT report. The organisation can then address the findings and request retesting.
Common Cloud Security Risks
Cloud security incidents often begin with simple configuration mistakes rather than advanced hacking techniques. These weaknesses can remain unnoticed because the cloud service continues to work normally even when the security settings are unsafe.
Some of the most common risks include:
- Excessive user or service-account permissions
- Publicly accessible storage buckets and backups
- Exposed access keys, passwords and API tokens
- Internet-facing databases or management services
- Weak network segmentation
- Inactive accounts that still have access
- Incomplete logging and security monitoring
Excessive permissions create one of the most serious risks. Businesses often give employees, administrators or service accounts more access than they need. If an attacker compromises one of these identities, they may gain access to sensitive data, security controls or critical workloads.
Public cloud storage also causes frequent data exposure. A misconfigured bucket, file share or backup location may allow unauthorized users to view or download customer records, source code, internal documents or database backups.
Cloud credentials remain another major target. Developers may accidentally store access keys, passwords or API tokens in source code, deployment files, logs or collaboration tools. Attackers can use these credentials to bypass normal login controls and access cloud resources directly.
Weak network rules may expose databases, remote-access services and administrative interfaces to the internet. Even when these services require authentication, public exposure gives attackers more opportunities to guess passwords or exploit known vulnerabilities.
Service accounts and application identities also require careful control. Cloud workloads use these identities to communicate with other services. If a service account has excessive permissions, an attacker who compromises one application may use it to reach storage systems, databases or other workloads.
Limited logging makes these attacks harder to detect. Security teams may record sign-ins but fail to monitor unusual downloads, permission changes, newly created access keys or suspicious API requests.
Attackers often combine several small weaknesses. For example, an exposed access key may provide limited access at first. The attacker may then retrieve application secrets, assume a more privileged role and connect to a production database.
A cloud security assessment helps the organization understand how these weaknesses connect. Instead of treating every issue as a separate finding, testers identify the complete attack path an attacker could use.
How Often Should Businesses Conduct Cloud VAPT?
Most organisations should conduct a comprehensive cloud security assessment at least once a year.
Businesses with rapidly changing environments, sensitive data or critical services may need more frequent testing.
A company should also arrange another assessment after a major migration, new application launch, significant permission change or introduction of a new SaaS platform.
Security incidents and major changes to cloud networks, containers or serverless applications should also trigger additional testing.
Continuous monitoring tools can detect some configuration changes, but they cannot fully replace manual testing. The right schedule depends on the organization’s risk level, rate of change and regulatory requirements.
Our guide to planning the right VAPT frequency explains these factors in greater detail.
How Should You Choose a Cloud VAPT Provider?
A cloud VAPT provider should understand cloud architecture, identity management, application security and penetration testing.
The provider should also have direct experience with the platforms the organisation uses. A company that operates across AWS, Azure and several SaaS applications needs a team that can evaluate how those environments connect.
The provider should manually validate findings, investigate privilege-escalation paths and explain the business impact of each weakness.
It should also protect the credentials and information it accesses, follow relevant cloud-provider policies and offer remediation retesting.
Businesses can use the broader criteria in our guide to choosing a suitable VAPT provider.
Final Thoughts
A cloud security assessment helps businesses identify vulnerabilities, configuration errors, excessive permissions and insecure integrations across AWS, Azure, Google Cloud and SaaS platforms.
It examines more than software vulnerabilities. It also reviews identities, storage, network exposure, access controls and relationships between cloud services.
Cloud providers protect the infrastructure they operate, but businesses must protect the accounts, resources and information they control.
Organisations that need independent testing across cloud infrastructure, applications, networks and SaaS environments can explore our VAPT Services.
Frequently Asked Questions
What does a cloud security assessment include?
A cloud security assessment may include cloud accounts, identities, permissions, storage services, databases, applications, APIs, virtual machines, containers and SaaS tenant settings.
How does cloud VAPT differ from a vulnerability scan?
A vulnerability scan mainly identifies known software flaws. Cloud VAPT also examines permissions, configurations, identities and possible attack paths.
Can testers assess AWS, Azure and Google Cloud resources?
Yes. Testers can usually assess customer-controlled resources within the provider’s policies and the agreed scope. They must not target the provider’s underlying infrastructure or another customer’s resources.
Does cloud VAPT include SaaS platforms?
Yes, when the agreed scope includes them. Testers usually review tenant settings, user access, sharing controls and connected applications.
Can automated tools replace manual cloud VAPT?
No. Automated tools provide useful visibility, but security specialists still need to validate the findings and identify complex risks involving identities and connected services.
