A cloud-native application protection platform (CNAPP) is a security product that brings several cloud security capabilities together in one platform, so teams can find and fix risks in cloud applications and infrastructure from development through to production. At its core it combines cloud security posture management (CSPM), which checks cloud account configuration, with cloud workload protection (CWPP), which secures the servers, containers and functions that run applications. Many CNAPPs add identity, code and data checks on top.
At a glance
- A CNAPP consolidates cloud security tools that were often bought separately, with posture management and workload protection as the common core.
- It typically covers infrastructure in public clouds such as AWS, Azure and Google Cloud, often across several at once.
- Many products connect related findings, such as a vulnerable workload that is internet-exposed and has broad permissions, to prioritize risk.
- Coverage beyond the core varies by vendor: identities, infrastructure code, container images, data and APIs are common add-ons.
- It secures what you build and run in cloud infrastructure; it does not on its own secure SaaS application settings.
What problem it solves
Organizations moving to the cloud often end up with a pile of separate tools: one for misconfigurations, one for workload vulnerabilities, one for container images, one for cloud permissions. Each produces its own alerts, and nobody can easily see that a single virtual machine is unpatched, open to the internet and able to read a sensitive storage bucket. That combination is what attackers look for, but separate tools report it as three unrelated low-priority findings.
A CNAPP aims to replace that sprawl with one view. By correlating configuration, workload and identity data, it can show which issues create a real path to sensitive data and which are noise. It also helps shift security earlier, by checking infrastructure code and images before they reach production, which matters when developers deploy changes many times a day in cloud-native environments.
How it works
Connection. The platform connects to your cloud accounts, usually through read-only access to cloud provider APIs. Depending on the product, it may also scan workload disks without agents, deploy lightweight agents for runtime protection, or both.
Posture checks. It compares cloud settings against security best practices and compliance frameworks, flagging issues such as public storage, missing encryption or overly broad network rules.
Workload and code scanning. It looks for vulnerabilities, malware and secrets in virtual machines, containers and serverless functions, and often in container images and infrastructure-as-code templates before deployment.
Identity and data. Many CNAPPs analyze cloud permissions to find excessive access, and some include data security posture management (DSPM) to locate sensitive data.
Prioritization and response. Findings are combined into a risk view, often shown as attack paths, and pushed to ticketing or developer tools. Runtime components may alert on or block suspicious activity.
When it matters for buyers
- When cloud usage grows past a few accounts. Manual reviews stop scaling, and misconfigurations multiply.
- When running more than one cloud. A multi-cloud footprint benefits from one policy and one view rather than each provider’s native tools separately.
- When consolidating security vendors. Replacing several point tools with one platform can cut cost and alert fatigue, if the platform’s weaker modules are good enough.
- When compliance requires evidence. Continuous posture reporting can support audits that cover cloud infrastructure.
- When clarifying responsibility. Under the shared responsibility model, configuring your cloud securely is your job, not the provider’s.
Questions to ask vendors
- Which capabilities are included in the base price, and which are separate modules?
- Which clouds, regions and services do you support, including Kubernetes and serverless?
- Is scanning agentless, agent-based or both, and what does each give us?
- How do you prioritize findings, and can you show the attack paths behind a high-risk alert?
- Do you scan infrastructure code and container images before deployment, and integrate with our developer tools?
- How is pricing calculated: per workload, per cloud account or by cloud spend?
- What read and write permissions do you need in our cloud accounts?
How it differs from CSPM
CSPM checks how cloud accounts and services are configured and flags misconfigurations. A CNAPP includes posture management and adds workload protection plus, depending on the vendor, identity, code and data checks, then correlates the results. In short, CSPM is one component; a CNAPP is the broader platform. For securing data in SaaS applications rather than cloud infrastructure, see SaaS security posture management (SSPM).
