A Cloud-Native Application Protection Platform (CNAPP) is an integrated security platform that combines cloud security posture management (CSPM), cloud workload protection (CWPP), cloud infrastructure entitlement management (CIEM), and application security capabilities into a single, unified solution. Gartner, which coined the term, describes CNAPPs as "a unified and tightly integrated set of security and compliance capabilities designed to protect cloud-native infrastructure and applications" across their full lifecycle from development through runtime.
A Cloud-Native Application Protection Platform (CNAPP) is a converged security category that brings multiple distinct cloud security disciplines under one platform. Gartner coined the term around 2021 to describe what the market was already doing: purpose-built cloud security tools were merging, because running a separate tool for cloud posture, one for workloads, and one for entitlements created exactly the noise and blind spots they were meant to prevent.
Before CNAPPs, organizations assembled separate tools for cloud security posture management (finding misconfigurations across cloud accounts), cloud workload protection (protecting running containers, VMs, and serverless functions), and cloud infrastructure entitlement management (controlling permissions across cloud services). Each tool had its own console, its own alert stream, and its own risk model, and the result was a fragmented picture of cloud risk that made it hard to see what actually mattered.
A CNAPP integrates these capabilities so findings from different layers can be correlated. A misconfigured storage bucket matters more when an overprivileged role could reach it, and a container vulnerability matters more when that container is internet-facing. CNAPPs surface these connected risks as one view rather than isolated alerts from disconnected tools.
CSPM continuously assesses cloud infrastructure for misconfigurations and compliance violations across AWS, Google Cloud, Azure, and other providers. It checks whether storage buckets are publicly exposed, whether security groups allow unrestricted inbound traffic, whether encryption is enabled, and whether configurations match baselines like the CIS Benchmarks or the requirements of SOC 2, ISO 27001, and HIPAA.
CWPP focuses on the workloads running in the cloud: containers, Kubernetes clusters, virtual machines, and serverless functions. It covers vulnerability scanning of container images and VM packages, runtime protection that detects anomalous behavior in running workloads, and enforcement of security policy on workload configuration. Container image scanning is a core CWPP function, catching known vulnerabilities before the workload runs in production.
CIEM addresses the permissions problem: identities, both human and machine, that hold more access than they need, inactive accounts with stale permissions, and overly permissive roles that create lateral-movement opportunities if compromised. In cloud environments, excessive permissions are among the most common and highest-impact findings.
Mature CNAPPs extend security into the development pipeline, scanning code, container images, and infrastructure-as-code templates before they reach production. This shift-left capability means the same platform that watches runtime cloud security also catches problems during development, when they are cheapest to fix.
Some CNAPPs include runtime detection and response: monitoring the cloud control plane, detecting anomalous API calls, and alerting or responding when attacker behavior appears in a live environment.
Cloud misconfiguration is one of the most common causes of cloud security incidents. Breach investigations, including the Verizon Data Breach Investigations Report, consistently identify misconfiguration and over-permissive access as primary contributors to cloud-related breaches. The reason is structural: a cloud environment changes constantly, and a configuration that was safe at deployment drifts into a liability as new resources, roles, and services are added. A CNAPP's CSPM layer is the continuous check against that drift, and its correlation across layers is what turns thousands of raw findings into the few that actually expose the business.
A full enterprise CNAPP is a large platform, and for a small team it can be more than the environment warrants. If you run one or two cloud accounts, you may not yet need a runtime workload-protection agent or a dedicated entitlement engine. What almost every team needs first is continuous posture management (CSPM), scanning of container images and infrastructure as code before they deploy, and one place to see and fix the results. The useful question is not whether you need a CNAPP but which CNAPP capabilities you need now. For most lean teams the answer is CSPM, container and IaC scanning, and remediation, with runtime workload protection and full entitlement management added as the environment grows.
Fencer covers the CNAPP capabilities a lean team needs most, and fixes what it finds. It runs CSPM across AWS, Google Cloud, and Azure, scans your container images and infrastructure as code (Terraform, CloudFormation, and Kubernetes manifests) before they deploy, inventories human and non-human cloud identities for review, and applies detection rules to cloud activity, all in the same platform as its application, code, and vulnerability management, with findings correlated and prioritized by real risk rather than raw severity. It is not a full enterprise CNAPP: it does not run a runtime workload-protection agent inside your containers. What it does instead is close the loop a startup actually feels, finding cloud and code risk, prioritizing it, fixing what it can (a direct cloud correction or a pull request), and re-scanning to confirm, without the overhead of a separate tool for each pillar.
CSPM (Cloud Security Posture Management) and CWPP (Cloud Workload Protection Platform) are distinct disciplines that address different layers of cloud security: CSPM focuses on cloud infrastructure configuration (are your S3 buckets private? Are security groups locked down?), while CWPP focuses on the running workloads themselves (are your containers free of known vulnerabilities? Are they behaving normally at runtime?). A CNAPP is the converged platform that integrates CSPM, CWPP, and typically CIEM and application security into a single solution. Rather than running separate tools for each discipline, a CNAPP unifies them so findings from different layers can be correlated and prioritized together.
Not necessarily in name, but in capability. Early-stage startups with simple cloud environments and a handful of services can often start with just CSPM to catch cloud misconfigurations. The case for a CNAPP's full suite grows as the organization adds containers and Kubernetes, expands to multi-cloud or multi-region, scales IAM complexity, or faces compliance requirements that demand demonstrable controls across the full cloud stack. The question that actually matters is whether the tools in use provide connected visibility rather than disconnected alerts. A formal CNAPP or an integrated security platform with equivalent capabilities both solve that problem; what you want to avoid is the multi-tool fragmentation that CNAPPs were designed to replace.
No, though they are related. DevSecOps is a methodology: the practice of integrating security into development workflows so security considerations are addressed throughout the software development lifecycle rather than only at the end. A CNAPP is a product category: a platform that provides cloud and application security capabilities, some of which can support DevSecOps practices (like CI/CD pipeline integration and pre-deployment IaC scanning). A CNAPP can be a useful tool within a DevSecOps approach, but DevSecOps is broader than any single platform, covering team culture, processes, and organizational practices alongside tooling choices.
