What Are CSPM Tools?
CSPM (Cloud Security Posture Management) tools are a type of software that helps organizations manage and secure their cloud environments. Their main goal is to reduce the attack surface of cloud environments by discovering vulnerabilities and detecting misconfigurations.
CSPM tools typically work by scanning an organization’s cloud environment for potential security issues and alerting the organization to any issues that are found. They commonly also provide recommendations for how to address those issues and help automate the process of resolving them.
Some examples of the types of security issues that CSPM tools may help identify include:
- Misconfigured cloud resources, such as servers or storage systems that have been set up with weak security controls.
- Software vulnerabilities discovered in packages, services, or libraries used in the cloud environment, and managing the process to remediate them.
- Unsecured data, such as sensitive information that is stored in the cloud without proper encryption.
- Permissions monitoring, to identify users or applications that have been granted access to cloud resources without proper authorization.

Why Are CSPM Solutions Important?
In a cloud computing environment, the provider is responsible for ensuring that the hardware and underlying infrastructure are secure, while customers must secure their own applications and data. This means that both the provider and the customer must work together to ensure that the cloud environment is secure. This is known as the shared responsibility model.
CSPM solutions are important because they help organizations manage and secure their cloud environments. Here are some security problems that CSPM solutions can help solve:
- Lack of visibility: Without proper visibility into their cloud environments, organizations may not be aware of potential security risks or vulnerabilities that could be exploited by attackers. CSPM solutions provide organizations with visibility into their cloud environments, helping them understand what resources they have deployed and how they are configured.
- Complexity of cloud security: Cloud environments can be increasingly complex, spanning multiple clouds, with many different resources, users, and applications that need to be secured. CSPM solutions can help organizations automate the process of identifying and addressing potential security issues, making it easier to manage the security of their cloud environments.
- Compliance challenges: Organizations may face challenges in meeting regulatory requirements and industry standards for security and privacy in their cloud environments. CSPM solutions can help organizations identify and address potential compliance issues, making it easier to meet their obligations.
- Lack of control: Without proper controls in place, organizations may not have the ability to manage who has access to their cloud resources and how that access is granted and managed. CSPM solutions can help organizations enforce access controls and manage user permissions in their cloud environments.
CSPM Key Features and Functionality
Cloud Security Posture Management provides discovery and visibility, misconfiguration management and remediation, continuous threat detection, and DevSecOps integration, as follows:
Discovery and Visibility
CSPM provides discovery and visibility into cloud infrastructure assets, creating an inventory of all cloud assets and their vulnerabilities.
Users can access a single source of truth across multi-cloud environments and accounts. Cloud resources and details are discovered automatically upon deployment, including misconfigurations, metadata, networking, security and change activity. Security group policies across accounts, regions, projects, and virtual networks are managed through a single console.
Misconfiguration Management and Remediation
CSPM eliminates security risks and accelerates the delivery process by comparing cloud application configurations to industry and organizational benchmarks so violations can be identified and remediated in real time. Misconfigurations, open IP ports, unauthorized modifications, and other issues that leave cloud resources exposed can be fixed with guided remediation. Storage is monitored so the proper permissions are always in place and data is never accidentally made accessible to the public.
Continuous Threat Detection
CSPM proactively detects threats across the application development lifecycle by cutting through the noise of security alerts with a targeted threat identification and management approach. The number of alerts is reduced because the CSPM focuses on the areas adversaries are most likely to exploit, vulnerabilities are prioritized based on the security context, and vulnerable code is prevented from reaching production.
CSPM reduces overhead and eliminates friction and complexity across multi-cloud providers and accounts. Cloud-native, agentless posture management provides centralized visibility and control over all cloud resources. Security operations and DevOps teams get a single source of truth, and security teams can stop compromised assets from progressing through the application lifecycle.
The CSPM should also integrate with DevOps tool sets that are already in use, which will enable faster remediation and response within the DevOps tool set. Reporting and dashboards provide a shared understanding across security operations, DevOps, and infrastructure teams.
Cloud Vendor CSPM Tooling
Cloud Security Posture Management (CSPM) tools are essential for organizations utilizing cloud services, as they help maintain a strong security posture and ensure compliance with industry standards. The leading cloud providers, such as AWS, Azure, and Google Cloud, offer built-in CSPM solutions that cater to different aspects of cloud security.
For example, AWS offers AWS Security Hub, a CSPM service that centralizes alerts, performs security checks, and facilitates automated responses. It provides a comprehensive view of an organization’s security state in AWS and helps track compliance with best practices and standards. The tool collects and centralizes security findings from AWS services, accounts, and supported partners. Key benefits of AWS Security Hub include centralized findings, automated security checks, and fast response.
Azure’s CSPM solution, Defender for Cloud, is a service that covers Azure, on-premises, and multi-cloud resources. It addresses crucial needs for managing security, such as providing a security score, offering recommendations for improvements, and sending alerts for real-time protection. Defender for Cloud continuously assesses an organization’s security posture and offers guidance for security hardening.
Google Cloud’s Security Command Center (SCC) is a security management platform that assists organizations in identifying, understanding, and responding to security threats. It provides a centralized platform for managing security across an organization’s Google Cloud infrastructure, as well as on-premises and hybrid environments. Features of SCC include threat detection, vulnerability management, compliance management, and incident management.
Each CSPM tool offers unique capabilities tailored to the specific cloud provider’s environment. However, they all have similar limitations, because they are limited to a specific cloud provider’s environment and lack some advanced security capabilities.
The Limitations of Cloud Vendor CSPM Tools
There are a few potential limitations of cloud vendor tools that organizations should be aware of:
- Cloud platform specific: One potential limitation is that organizations may become dependent on the vendor for the availability and functionality of the tools. Most companies use more than one cloud provider, making cloud vendor CSPM tools insufficient to manage their overall cloud security posture.
- Limited control: Organizations may have limited control over the configuration and customization of cloud vendor tools. This can make it difficult to customize the tools to meet the organization’s specific needs and requirements.
- Complex: CSPM tools are often built from several solutions, making them complex to deploy and maintain.
- Compatibility: Cloud vendor tools may not be compatible with other systems or tools that the organization is using, which can limit their effectiveness.
Overall, while cloud vendor tools can provide many benefits, organizations should carefully consider the potential limitations and ensure that they choose tools that meet their needs and requirements.
What Are Next-Generation CSPM Tools?
