Decision guide · Cloud Security Posture and CNAPP
Choosing CSPM or CNAPP: consolidating the cloud-security stack
Cloud security stacks historically consist of 3-7 single tools. Gartner coined CNAPP in 2021 as the consolidation category. The tool decision becomes a platform decision with a 5-7 year horizon.
TL;DR
The CNAPP market is consolidating into a manageable number of platforms. For most organisations, cutting tool sprawl weighs more than the last percentage point of depth in any single discipline.
Who owns this decision
CISO with cloud architecture. Application owner and DevSecOps in the steering group.
Key criteria to weight
Multi-cloud depth
AWS, Azure, GCP, OCI, Alibaba; vendors are not equally deep everywhere.
Agentless and/or agent-based
Agentless gives fast coverage. Agents give deeper runtime visibility.
K8s and container maturity
KSPM and container runtime are the fastest-growing sub-segment.
Data security (DSPM)
Data Security Posture Management is becoming mandatory in 2026/2027.
EU data residency and SIEM integration
Findings must not be processed only in the US.
TCO and consolidation lever
CNAPP should replace 3-5 tools.
Step-by-step decision flow
- 1
Cloud inventory and workload map
Which clouds, which workload types, which current tools.
- 2
Use-case definition
Misconfig detection, runtime threat detection, IAM right-sizing, K8s posture, IaC pre-deploy, data discovery.
- 3
Vendor longlist
Wiz, Palo Alto Prisma Cloud, CrowdStrike Falcon Cloud Security, Microsoft Defender for Cloud, Lacework, Sysdig, Orca Security, Aqua Security.
- 4
PoC with real workloads
30-60 day trial in own cloud.
- 5
Memo and consolidation plan
Decision memo plus sunset list of replaced tools.
Compliance note
NIS2 Art. 21 (e), DORA Art. 9, ISO 27002 A.5.23, BSI C5.
Common pitfalls
- CNAPP is introduced but old tools keep running. Double cost.
- Agent strategy unclear. The tool does not cover everything.
- Findings stream into the SOC but no one prioritises. CNAPP fatigue.
- DSPM is ignored. Data risks remain blind.
FAQ
When is CSPM alone enough, when do I need CNAPP?
Single cloud, few workload types, no K8s: native CSPM enough. Multi-cloud, K8s, deep runtime detection: CNAPP.
What role does DSPM play in CNAPP?
DSPM finds sensitive data in cloud stores and rates access and encryption. In 2026/2027 DSPM becomes mandatory in CNAPP.
EU hosting for CNAPP, what do I have to check?
Telemetry endpoint region, finding storage region, key custody, support data access.
