Agentless coverage and time to value
Weight 18%
Defender: Agentless VM, secrets and Kubernetes scanning exist, but only in the paid Defender CSPM and Defender for Servers Plan 2 tiers.
Cortex Cloud: Posture, vulnerability and attack-surface modules work from cloud APIs, but the pages we reviewed lead with a runtime agent and do not name agentless workload scanning.
Runtime protection depth
Weight 16%
Defender: Server runtime protection comes through Defender for Endpoint EDR across Azure, AWS, GCP and on-premises machines.
Cortex Cloud: Formed by merging Prisma Cloud with Cortex CDR; a performance-optimized agent stops attacks as they execute.
Risk prioritization and attack paths
Weight 18%
Defender: Attack path analysis, cloud security explorer and internet exposure analysis sit in Defender CSPM.
Cortex Cloud: SmartScore and SmartGrouping rank findings by real exposure, with attack path analysis across identities and data.
Code-to-cloud and AppSec
Weight 14%
Defender: Code-to-cloud mapping and agentless code-to-cloud container assessment are included in Defender CSPM.
Cortex Cloud: Application security is one of the platform's four pillars, aimed at stopping risk before it reaches production.
AI workload security
Weight 12%
Defender: AI-SPM in Defender CSPM plus Defender for AI Services, billed per 1,000 tokens.
Cortex Cloud: AI-SPM maps models, datasets and agents, flags model poisoning and supply chain risk, and classifies data used for RAG.
Ecosystem and integrations
Weight 12%
Defender: Native to Azure and Microsoft's security stack, with AWS and GCP resources covered and billed alongside Azure.
Cortex Cloud: Sits in the Palo Alto Networks Cortex portfolio next to its security operations products, and Prisma Cloud customers move onto it.
Pricing transparency
Weight 10%
Defender: Foundational CSPM is free, paid plans bill per resource with a public cost calculator, and there is a 30-day free trial.
Cortex Cloud: No public price list; Palo Alto Networks includes CNAPP at no additional cost for Cortex Cloud Runtime Security customers.
Scores are 0 to 5. The marker leans toward the stronger vendor; a gap of 1.5 or more pins it to the end. How to read these bars
