Cloud security is essential for ensuring the safety and integrity of data and applications in the cloud. Organizations often face a choice between using cloud service provider (CSP) proprietary security solutions and third-party security solutions. Understanding the differences and benefits of each can help in making an informed decision.
As cloud ecosystems gain complexity, organizations face critical decisions regarding their security strategies. Two primary options exist: leveraging security solutions provided by cloud service providers (CSPs) or adopting third-party cloud-native security solutions from specialized vendors. Exploring the differences, advantages, and challenges of both approaches helps in making an informed decision.
With cloud services come CSP proprietary tools that offer deep integration with respective cloud platforms. In addition to providing seamless user experiences, they often include advanced features tailored to the capabilities of the cloud service provider, which makes them highly effective for users invested in a single cloud ecosystem. CSP tools ensure tight security, compliance, and monitoring capabilities, leveraging the native infrastructure to its fullest potential.
AWS Security Hub, Azure Security Center, and Google Cloud Security Command Center are examples of CSP proprietary tools. Each of these are designed to integrate tightly with their respective cloud platforms:
While these tools leverage the specific capabilities and integrations of their respective cloud platforms, most third-party cloud-native tools offer cross-platform compatibility.
In contrast to CSP-built security tools, third-party cloud-native tools enable users to manage and secure applications across multicloud and hybrid cloud environments.
CNAPP solutions, for instance, provide comprehensive security capabilities that span multiple cloud environments, giving organizations consistent protection and visibility across diverse cloud infrastructures. Designed to protect cloud-native applications throughout their lifecycle, CNAPPs encompass multiple security functions — continuous visibility, threat detection and response, compliance management, identity and access management (IAM), workload protection, automated remediation, and more. They also integrate with DevOps tools to embed security into the software development lifecycle (SDLC), ensuring continuous protection from code to cloud.
While CSP proprietary tools excel in seamless integration within their cloud environments, third-party tools like CNAPP provide broader coverage, allowing organizations to adopt a multicloud strategy without sacrificing security and compliance.
CSP proprietary security solutions provide seamless integration within their ecosystems, leveraging native infrastructure to deliver enhanced security, compliance, and monitoring capabilities. Users benefit from a cohesive experience, as these tools are designed to work harmoniously with other services offered by the cloud provider.
Third-party cloud-native security solutions offer cross-platform flexibility, enabling organizations to manage and secure their applications across multiple cloud environments. This flexibility reduces vendor lock-in and allows for a more versatile security strategy, catering to organizations that adopt a multicloud or hybrid cloud approach.
CSP security solutions come with built-in security controls optimized for their environments. These controls ensure that users can easily implement security best practices and maintain compliance with regulatory requirements.
Third-party security solutions often provide advanced features that go beyond the capabilities of native tools. These features include comprehensive visibility, threat detection, and compliance management across diverse cloud infrastructures. By integrating with various other security tools and technologies, third-party solutions offer a holistic approach to cloud security.
The challenge of a multicloud ecosystem comes in many forms — identity, data flow, comprehensive context for risk prioritization and attack path analysis.
Consider the complexity of cloud identity and access management (IAM) frameworks. In the best of circumstances, it poses significant challenges for security practitioners. In public cloud environments, the aim remains to enforce least-privileged access to reduce the attack surface. CSP proprietary tools, however, often fall short in effectively identifying and managing net-effective permissions.
CSP proprietary tools, like AWS Security Hub, Azure Security Center, and Google Cloud Security Command Center, offer prebuilt privileges and managed permissions to help organizations get started with IAM policies.
Despite these initial conveniences, these tools require organizations to manually assess raw permissions, such as allow, deny, service control policies (SCP), and boundaries. The manual assessment becomes a daunting and error-prone task, especially when external identity providers (IdPs) and single sign-on (SSO) providers, such as Okta and Azure Active Directory, add another layer of complexity.
The integration of IdPs can create gaps in visibility and make it difficult to accurately determine user access, increasing the risk of security breaches and regulatory noncompliance.
CIEM tools address these limitations by auto-calculating net-effective permissions across cloud and multicloud environments. CIEM tools, such as Prisma Cloud, provide a centralized platform for managing and monitoring access rights. They offer features like near real-time monitoring, automated workflows, and intelligent graph visualizations, making it easier to identify and remediate overly permissive access.
By unifying multicloud IAM policy models and mapping external IdPs to the CSP IAM framework, CIEM tools simplify the enforcement of least-privileged access. Organizations using CIEM tools can effectively reduce their attack surface and enhance their cloud security posture, ensuring consistent security across all cloud environments.

In practice, an organization using CSP proprietary tools might secure data within a single cloud platform effectively but struggle to maintain the same level of security across multiple clouds. Sensitive data, for instance, might be securely stored and monitored within AWS, but when transferred to Azure for analytics, CSP tools lack the capability to track and secure the data in the new environment. This limitation increases the risk of data breaches, as well as compliance violations.
Data security posture management (DSPM) solutions continuously scan all cloud environments to identify where sensitive data resides, classify it based on its risk level, and monitor how it’s accessed and processed. Complete visibility enables organizations to enforce consistent security policies and detect potential vulnerabilities that CSP tools miss.
Data detection and response (DDR) goes a step further by providing near real-time data monitoring and response capabilities, allowing security teams to detect suspicious activities or data exfiltration attempts as they happen. By integrating DSPM and DDR, organizations gain the ability to proactively manage data security risks, respond swiftly to incidents, and protect sensitive data across all cloud environments, regardless of the underlying CSP.
CSP security solutions are typically cost-efficient, as they’re designed to work within the existing cloud service provider’s ecosystem. Users can take advantage of bundled pricing and streamlined billing processes.
Investing in third-party security solutions may involve additional costs, but these solutions can offer significant value through specialized features and cross-platform capabilities. Organizations must weigh the potential benefits against the costs to determine the best fit for their needs.
CSP security solutions are optimized for their native environments, providing users with tools that are specifically designed to work within the cloud provider’s infrastructure. This optimization ensures efficient performance and ease of use.
