Orca vs Prisma Cloud when the CNAPP choice is SideScanning or a module stack with runtime agents

Twelve AWS accounts, nobody sure what runs in half of them, and a runtime team that refuses another host agent. That ticket starts most CNAPP evaluations between these two. Both sell agentless posture, vulnerability, identity, and data scanning across AWS, Azure, and Google Cloud. They split on how deep the agentless read goes and where runtime blocking is licensed.

Orca reads runtime block storage out of band through SideScanning and rebuilds each workload without code running inside it, with the Orca Sensor as an optional runtime add-on. Palo Alto Networks sells Prisma Cloud as Foundations for agentless posture, Advanced for host, container, and serverless runtime plus WAAS, and Compute Edition for self-hosting, with Cortex Cloud Posture Management and Cloud Runtime Security as the newer workload-unit packaging.

Buy Orca when agentless coverage of every workload must come first with runtime added only where needed. Buy Prisma Cloud when runtime protection, WAAS, and a self-hosted console must sit in one Palo Alto contract.

Overview

	Orca	Prisma Cloud
Primary use case	Agentless-first CNAPP built on SideScanning plus context-aware risk scoring, attack paths, and reachability across multicloud accounts	CNAPP modules for posture, vulnerability, identity, data, and code scanning, plus runtime workload protection and WAAS on Advanced or Compute Edition
Day-to-day workflow	Connect cloud accounts read-only, review prioritized alerts by risk score and attack path, and scope the Orca Sensor to workloads that need runtime detection	Choose the licensed module, deploy Defenders where runtime is in scope, and work posture, runtime, and WAAS findings in the Prisma Cloud or Cortex Cloud console
Main buying consideration	Sales quote. No public USD SKU on orca.security when checked 10 Oct 2026. AWS Marketplace private offers carry the contract	Prisma Cloud credits for Enterprise modules and Cortex Cloud workload units for Posture Management and Cloud Runtime Security. No public dollar per credit or workload on the license pages checked 10 Oct 2026

We reviewed Orca SideScanning and Orca Sensor documentation and the Lemonade case study, plus Prisma Cloud license documentation for Foundations, Advanced, and Compute Edition and the Cortex Cloud Posture Management and Cloud Runtime Security packaging, on 10 Oct 2026. We did not run either platform in a paid tenant.

Editions and pricing

Neither vendor prints a dollar. Orca quotes a platform; Palo Alto quotes credits or workload units depending on which packaging the order uses.

	Orca	Prisma Cloud
How it is sold	Orca Cloud Security Platform on a sales quote, with the Orca Sensor as an optional runtime component	Prisma Cloud Enterprise credits by module, or Cortex Cloud workload units for Posture Management and Cloud Runtime Security. Compute Edition sold for self-hosted deployment
Figure on the public page	No USD on orca.security when checked 10 Oct 2026	No USD per credit or per workload on Palo Alto license pages checked 10 Oct 2026
What the unit counts	Cloud workloads and assets in scope of the platform quote	Credits consumed per resource type and module, or protected workloads in Cortex Cloud packaging

Agentless scanning and prioritization

Both platforms scan workloads without agents. The documented split is a block-storage rebuild with one risk score versus a module set where agentless is the Foundations tier.

	Orca	Prisma Cloud
Agentless read	SideScanning reads block storage out of band and rebuilds the filesystem for vulnerabilities, malware, misconfigurations, secrets, and sensitive data	Agentless workload scanning in Cloud Security Foundations snapshots volumes for vulnerabilities and compliance findings
Risk scoring	Multi-factor score on severity, exploitability, accessibility, and business impact, with attack paths and reachability	Posture and vulnerability findings with attack path analysis across CSPM, CIEM, and DSPM modules licensed on the order
Coverage beyond workloads	CSPM, CIEM, DSPM, and AI security posture on the same Unified Data Model	CSPM, CIEM, DSPM, AI-SPM, ASM, KSPM, and CI/CD posture in the Posture Management bundle

Runtime protection and deployment

Both now sell runtime. The split is an optional sensor on an agentless platform versus Defenders on a runtime license.

	Orca	Prisma Cloud
Runtime component	Optional Orca Sensor for real-time cloud detection and response on selected workloads	Defenders for hosts, containers, and serverless on Cloud Security Advanced or Cloud Runtime Security
Web application protection	Not part of the Orca platform documentation reviewed	WAAS for web application and API protection on Advanced, Compute Edition, and Cloud Runtime Security
Self-hosted option	SaaS only	Compute Edition is customer-hosted with agentless and agent-based protection

Favor Orca when the documented requirement is SideScanning of every workload without code in the environment, one multi-factor risk score, and an optional Orca Sensor where runtime matters. Favor Prisma Cloud when the documented requirement is Defenders for host, container, and serverless runtime, WAAS, Compute Edition self-hosting, and credit or Cortex Cloud workload-unit packaging.
