The adoption of cloud native applications built on containers, microservices and serverless functions has skyrocketed in recent years. This dynamic infrastructure enables faster delivery of new features and better scalability. However, traditional security tools are often inadequate for these modern, complex environments.
This is where the cloud native application protection platform (CNAPP) enters the scene. According to Gartner, the CNAPP market will grow at a CAGR of 46% to reach $2.3 billion by 2025.
So what exactly is a CNAPP, and why should you consider it? This comprehensive guide will cover:
- The growing need for CNAPP solutions
- Core capabilities of a CNAPP
- Its key components explained
- How a CNAPP works
- Implementation considerations
- Evaluation criteria for selecting a vendor
- Future directions for CNAPP
Why You Need a Cloud Native Application Protection Platform
Organizations are quickly migrating business-critical workloads to the cloud and adopting cloud native technologies. However, this rapid cloud adoption has opened up new attack surfaces and risks, such as:
- Misconfigurations of cloud resources
- Overly permissive identities and credentials
- Vulnerable application code
- Increased complexity across hybrid or multi-cloud deployments
The dynamic nature of cloud native apps limits the effectiveness of traditional security tools that rely on more static network perimeters.
Integrating security across separate point solutions is complex, leading to dangerous visibility gaps. Manual processes also cannot keep pace with the rate of change.
This is where a CNAPP comes in – it unifies multiple security capabilities into a single cloud native platform designed specifically for these modern environments.
Key benefits of adopting a CNAPP include:
- Unified visibility and control across cloud workloads, identities and configurations from a single pane of glass
- Early detection of risks across the application lifecycle
- Faster response with automated investigation and one-click remediation
- Simplified operations with consolidated tools, policies and processes
- Reduced risk surface by integrating security seamlessly into CI/CD pipelines
- Optimized cloud investments by preventing security issues that can degrade application reliability or performance
According to an ESG study, 63% of organizations surveyed believe a CNAPP is essential for maintaining a strong cloud security posture.
Key Components of a CNAPP
While CNAPP vendors may differ in their specific approach, most share a core set of capabilities that enterprises need to secure cloud native workloads.
Cloud Security Posture Management (CSPM)
A CSPM continuously assesses cloud configurations against security best practices and compliance frameworks. It can automatically detect issues like open security groups, unprotected data buckets or overly permissive role assignments.
Cloud Workload Protection Platform (CWPP)
A CWPP secures the runtime environment, analyzing traffic, user behavior and activity across containers, functions and VMs to detect threats. It provides next-gen protection against malware or suspicious patterns that indicate compromise.
Cloud Infrastructure Entitlement Management (CIEM)
CIEM manages permissions across cloud accounts and assets to enforce least privilege access. It can identify unnecessary entitlements and stale roles to reduce attack surface.
Data Security Posture Management (DSPM)
DSPM discovers sensitive data across cloud data stores and monitors its usage. It can find stolen API keys in GitHub repos, unprotected personal data buckets, or suspicious queries on a database.
Cloud Detection and Response (CDR)
CDR uses analytics and threat intelligence to turn large volumes of cloud telemetry and events into actionable incidents, risks and alerts. Analysts can quickly understand the context and root cause to respond appropriately.
Cloud Network Security
Cloud network security provides zero-trust protections between services like next-gen firewalls, API gateways, microsegmentation and web application firewalls.
DevSecOps Integration
Another key element is deep integration into CI/CD pipelines to embed security checks that run alongside application code. Infrastructure-as-code scanning also becomes important for early detection of risks.
How Does a CNAPP Work?
Now that we’ve covered the key components, let’s discuss how a CNAPP combines them to secure cloud native environments effectively:
1. Holistic visibility – The CNAPP consolidates and correlates signals from across infrastructure, identities, networks, workloads and data planes. This connects the dots to assess risk context accurately.
2. Continuous compliance – Combining CSPM and CIEM capabilities, it continuously monitors for drift from secure configurations and least privilege access, auto-remediating where possible.
3. Runtime threat prevention – CWPP and cloud network security provide layered defenses around runtime workloads to block sophisticated threats.
4. Rapid detection & response – Powerful analytics spot hard-to-detect threats while CDR enables quicker investigation and one-click remediation.
5. Embedded security – Deep CI/CD integrations shift security left, enabling dev teams to code securely and infrastructure-as-code scanning.
6. Unified controls – Converging these capabilities into a single platform simplifies cloud security ops. Common policies, playbooks and dashboards enable consistency.
The end result is more proactive risk reduction powered by cloud speed and scale.
Evaluating CNAPP Solutions
As the market matures, most CNAPP vendors will converge on a common set of core capabilities. However, key factors to consider when comparing options include:
1. Native cloud support – The degree of visibility, data access and response actions across AWS, Azure, GCP and Kubernetes.
2. Analytics-driven detection – Ability to leverage cloud data at scale to detect subtle but serious risks.
3. Response automation – Built-in workflows to instantly respond to hundreds of alert scenarios.
4. DevSecOps integration – Embedding security within CI/CD pipelines is vital.
5. Holistic coverage – Unified visibility and control for hosts, containers, functions, data.
6. Ease of use – How intuitive and frictionless is it for both security analysts and application teams.
7. Operational overhead – Some CNAPPs have high sensor maintenance or complex management.
As cloud environments keep evolving, the CNAPP that offers the best protection while optimizing operator overhead will provide the best long-term value.
The Future of Cloud Native Security
While still early days, the CNAPP concept represents the future of cloud security – delivering integrated protection designed for modern application environments.
As CNAPP platforms mature, we can expect more advanced risk analysis, greater automation via AI/ML and embedding security earlier into development toolchains.
Support for confidential computing, IoT and edge workloads may also expand the definition of CNAPPs even further.
Conclusion
The acceleration of cloud native adoption requires a new approach to security centered on dynamic applications rather than static networks. CNAPPs consolidate multiple security capabilities into a unified platform to provide comprehensive protection, compliance and governance across cloud workloads.
Core components like CSPM, CWPP and CIEM combine with advanced analytics, automation and DevSecOps integration to enable proactive defense and rapid response.
As modern applications become critical business drivers, CNAPPs provide the cloud native protection they demand while optimizing both security and agility. The time for piecemeal cloud security is over. CNAPPs represent the future.
